The present disclosure relates generally to musical instruments, and more particularly to switching systems for musical instrument pickups.
A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly. Most electric guitars and electric basses use magnetic pickups. Acoustic guitars, upright basses and fiddles often use a piezoelectric pickup.
A typical magnetic pickup is a transducer (specifically a variable reluctance sensor) that consists of one or more permanent magnets (usually alnico or ferrite) wrapped with a coil of several thousand turns of fine enameled copper wire. The magnet creates a magnetic field that is focused by the pickup's pole piece or pieces. The permanent magnet in the pickup magnetizes the guitar string above it, creating a magnetic field around the string that is in alignment with the magnetic field of the pickup magnet. When the string is plucked, the magnetic field around it moves up and down with the string. This moving magnetic field induces a current in the coil of the pickup.
The pickup is connected with a patch cable to an amplifier, which amplifies the signal to a sufficient magnitude of power to drive a loudspeaker (which might require tens of volts). A pickup can also be connected to recording equipment via a patch cable. The pickup is most often mounted on the body of the instrument, but can be attached to the bridge, neck and/or pickguard.
Single-coil pickups act like a directional antenna and are prone to pick up mains hum—nuisance alternating current electromagnetic interference from electrical power cables, power transformers, fluorescent light ballasts, video monitors or televisions—along with the musical signal. Mains hum consists of a fundamental signal at a nominal 50 or 60 Hz, depending on local current frequency, and usually some harmonic content.
Mains hum can be overcome by using a humbucking pickup. A humbucking pickup is composed of two coils, with each coil wound reverse to the other. Each set of magnetic poles is also opposite in polarity. Since ambient hum from electrical devices reaches the coils as common-mode noise, it induces an equal voltage in each coil, but 180 degrees out of phase between the two voltages. These effectively cancel each other, while the signal from the guitar string is doubled.
When wired in series, as is most common, the overall inductance of the pickup is increased, which lowers its resonance frequency and attenuates the higher frequencies, giving a less trebly tone (i.e., “fatter”) than either of the two component single-coil pickups would give alone. An alternative wiring places the coils in buck parallel, which has a more neutral effect on resonant frequency and reduces the output while extending high frequency response.
A side-by-side humbucking pickup senses a wider section of each string than a single-coil pickup. By picking up a larger portion of the vibrating string, the higher frequency harmonics are cancelled in the signal produced by the pickup, resulting in a “fatter” tone. Humbucking pickups in the narrow form factor of a single coil, designed to replace single-coil pickups, have the narrower aperture resembling that of a single coil pickup. This results in less cancellation of harmonics and a brighter sound, more like a single coil pickup.
Most electric guitars have two or three magnetic pickups. A combination of pickups is called a pickup configuration, usually notated by writing out the pickup types in order from bridge pickup through mid pickup(s) to neck pickup, using “S” for single-coil and “H” for humbucker. Typically the bridge pickup is known as the lead pickup, and the neck pickup is known as the rhythm pickup.
Every pickup coil has two basic properties that affect how they will sound when they are combined with others. These properties are called phase and magnetic polarity. Phase is the direction current travels through the pickup, and polarity is the orientation of the magnetic field. With both properties, there are only two options. Phase can either be “top coming” or “top going”, determined by winding direction of the coil, or “counter-clockwise” or “clockwise”, indicating the direction of rotation of the spindle of the winding machine. Magnetic polarity can either be “south” or “north.”
A typical application of these principles is with single coil pickups. One property of single coils is that depending on their phase and polarity, it may be possible for them to be hum cancelling when combined. The key to a strong, full tone with hum cancellation is to combine single coil pickups that have opposite phase (or “wind”) and opposite polarity with respect to one another. If one pickup is north polarity, top coming, the other must be south polarity, top going.
Humbuckers all operate on this principle. The two coils have opposite wind and opposite polarity. When combined in series mode, it produces a fat, meaty tone and no hum. Splitting a humbucker will, of course, bring back the hum, but give a brighter, cleaner sound with more high frequency content. Combining the two coils in parallel mode maintains hum-cancellation and produces a brighter tone than series mode, but with less output and less brightness than split mode.
When single coil pickups are mismatched, either hum or phase cancellation occurs. Phase cancellation occurs when two pickups interfere with each other's frequency responses to produce a “thin” or “hollow” sound. When this happens, the pickups are said to be “out of phase”. While this is something that most performers might try to avoid, others might like the unique sound in certain situations, and some may use an out-of-phase tone by choice. In some situations, performers may want to switch between an in phase tone and an out of phase tone during a performance.
For two single coil pickups to be in phase, both the magnet polarity and the wind direction must either be identical, or both parameters must be opposite. In other words, two pickups with the same wind direction and magnetic polarity will be in phase, and so will two pickups that have opposite magnetic polarities and wind directions with respect to one another. If the two pickups have the same wind directions but different magnetic polarities, or the same magnetic polarities but different wind directions, they will be out of phase with one another.
The most common reason for two single coils to be out of phase is that one of them is wired backwards. The lead that was supposed to be connected to ground is connected to the output, and vise versa. If phase cancellation occurs when combining two single coils, the easiest cure is to swap the lead wires on one of them.
For two coils to be in phase and hum cancelling, one of them (only) will need to be reverse wind, reverse polarity (or “RWRP”). However, one problem is that different manufacturers may have different phase and polarity standards, making them a challenge to mix and match. However, if one knows in advance (or figures out upon installation), the problem can be overcome by rewiring the pickups.
As previously mentioned, many if not most instruments will use multiple pickups to capture sound. These pickups are hard wired to a toggle switch, the configuration of which determines which pickup or combination of pickups are used to transfer the string vibrations into an electrical signal. Each pickup is wired to the toggle switch with each pickup coil having a specific desired setting (e.g., in phase, or out of phase). In traditional electric guitars, for example, the audio signal coming from pickups has historically been controlled using mechanical switches that must be manually activated or operated to change the tone of the pickups. Adjustability between in phase and out of phase tones is highly desirable because it can produce many different tones, which increases the versatility of the instrument. Wiring a pickup requires skill and, even when wired correctly, results in fixed coil settings that require a change to the wiring to be modified. This process can be cumbersome and is not easily modified even with the right tools and knowledge. Thus, a need exists for a switch system that allows players to change their coil settings quickly and easily, enables many different tone combinations, and works seamlessly with pickups from different manufacturers.
Disclosed herein are wireless switching systems for use with stringed musical instruments (e.g., guitars) to enable a user to seamlessly change pickup coil settings without having to adjust the wiring between the switch and the pickups. In one example aspect, a system includes a musical instrument having one or more pickups attached thereto, a switch device or mechanism mounted on the musical instrument and in electronic communication with the one or more pickups, a computing device configured for wireless communication with the switch, and a switch management software application program (or “app”) stored on and executable by the computing device, in which a user is able to use the switch management app to remotely change the pickup coil settings of the user's instrument without having to rewire the switch device.
In some embodiments, the switching system of the present disclosure is an analog signal switch device and conditioner that can be controlled and programmed remotely, using radio waves, in communication with a software app on a computing device such as a smart phone, smart watch, tablet computer, desktop computer, and/or a laptop computer. The switching system of the present disclosure reduces or removes the need of skill in that pickups of any kind are directly connected to the switch in a standard way, and the switching system manages the wiring, signal conditioning, and all the needed connections to enable easy changing of the coil settings.
The switch device can be remotely connected to a smart phone or any other suitable computing device with wireless communication capability, offering an immediate preview of the sound differences between various pickup coil settings. Once the desired coil setting configuration is saved, the switching system can work in a standalone mode, simulating a normal mechanically operated guitar switch. The use of radio waves to exchange data removes the need to use any kind of cable or to open the instrument to program or rewire the switch device, and enables remote programming of the device in real time.
Additionally, the switching system of the present disclosure may accept inbound data to control the instrument signal path, may be used to collect the data coming from the instrument (lever position, potentiometer position, accelerometer, buttons, etc.), and may also be used to control other wireless-enabled peripheral devices.
Among other things, the switching system of the present disclosure boasts the following useful features.
In some embodiments, the data transfer and data exchange are wirelessly supported by radio waves. Controlling the analog signal path wirelessly enables easy access to the switch device and/or mechanism, with no need to remove instrument covers, plug in connector, or use special adapter to change the coil settings. Moreover, the use of radio standards such as WiFi, Bluetooth, and Bluetooth Low Energy (BLE) enable the use of the switching system with a wide number of common computing devices, such as smart phones, tablets, laptops, etc. to program and control the switch device remotely. Wireless control of the switch device enables it to be programmed in real time on a stage or in any situation where using a cable is impractical. Using radio waves can enable the transfer of the MIDI (Musical Instrument Digital Interface) protocol over the air, making it easy to connect the instrument to a sequencer or control peripheral devices from the musical instrument itself. This may be particularly useful during a live performance to control (and/or be controlled) without returning in a predefined place.
In some embodiments, the switching system of the present disclosure includes a simple user interface (UI) including touch screen interface. The UI converts complex wiring parameters in simple colors and is designed to be easy.
In some embodiments, the switching system of the present disclosure may use a proprietary serial communication protocol with a dynamic byte length and a closed loop check to ensure data consistency.
In some embodiments, the switching system of the present disclosure uses advanced power handling techniques to reduce the power consumption. Power is a necessary and important component of a wireless switching system. Traditionally, the existing switching systems are passive arrays of contacts mechanically actuated and require no power. The switching system of the present disclosure includes firmware designed to keep the processor always sleeping, using low level programming approach. To achieve this result, a wakeup protocol is executed before the operating system boots up, and then the CPU is forced back to sleep when the user is finished.
In some embodiments, the switching system of the present disclosure implements a true analog signal path without bypass capacitor or bias resistor in the signal path to ensure a wide frequency response and preserve the signal phase. This removes even unwanted capacitive loads.
In some embodiments, the switching system of the present disclosure may capture, record, and/or otherwise use lever position information (e.g. for electric guitars), analog audio streams that may be present on the instrument, and/or information of other sensors that may be present on the instrument or on the switch device itself (e.g., potentiometers, accelerometers, position sensors, buttons, etc.), and transmit the captured, recorded, or otherwise used data to the user's computing device or other computing systems, for example to control other peripheral wireless-enabled devices using a MIDI protocol or any other serial protocol.

It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. The wireless switching system for musical instruments and related methods disclosed herein boasts a variety of inventive features and components that warrant patent protection, both individually and in combination.
Disclosed herein are pickup configuration switching systems for use with stringed musical instruments (e.g., guitars) to enable a user to seamlessly switch between pickup configurations without having to adjust the wiring between the switch and the pickups. In one example aspect, a system includes a musical instrument having a plurality of pickups attached thereto, a switch device mounted on the musical instrument and in electronic communication with the plurality of pickups, a computer or computing device configured for wireless data communication with the switch device, and a switch management software application program (or “app”) stored on and executable by the computing device, in which a user is able to use the switch management app to remotely change the pickup configuration of the user's instrument without having to rewire the switch device.
In some embodiments, the interactive switch management app 18 may be embodied in a non-transitory computer-readable storage medium and may comprise a set of instructions that when executed by a processor cause the computing device 16 to perform the various functions described herein (e.g., present selectable display icons to a user on the user interface of the computing device 16 that represent pickup coil configurations on the user's stringed instrument, receive input from the user via the user interface regarding the user's desired coil configuration, and wirelessly communicate with the switch device 12 mounted on the user's stringed instrument to implement the desired coil configuration as selected by the user).
In some embodiments, the system 10 may include a data processing system 20 in communication with the computing device 16 and/or the switch device 12. The data processing system 20 can include one or more computing devices in a computer system or communication network accessible via the Internet (also referred to as “the cloud”), e.g., including servers and/or databases in the cloud.
In some embodiments, the computing device 16 and/or app 18 may receive other data from the instrument, for example lever position, potentiometer position, accelerometer position, buttons, digital audio streams, etc.
In some embodiments, the switching system 10 of the present disclosure may be configured for use with a variety of musical instruments, for example stringed instruments. By way of example, the stringed instruments may be fretted (e.g., guitars, banjoes, mandolins, etc.) or non-fretted (e.g. violins, violas, cellos, and the like).
The interactive switch management app 18 of the computing device 16 associated with the switch device 12 provides a user interface to allow the user to manage his/her switch configuration, as well as other data captured from the instrument.

Once the onboard processor has been programmed via the app, the switching system can operate totally independent of the app, enabling the app and Bluetooth communication to the turned off, thus conserving power.
In some embodiments, the switching system of the present disclosure includes a simple user interface (UI) 70 (See, e.g.,
By way of example only,
For example, the processor 46 can include a central processing unit (CPU) or a microcontroller unit (MCU). For example, the memory 48 can include and store processor-executable code, which when executed by the processor 46, configures the control unit 40 to perform various operations, e.g., such as receiving information, commands, and/or data, processing information and data, transmitting or providing information/data to another device (e.g., computing device 16), and controlling the MUX 42, for example using Musical Instrument Digital Interface or MIDI protocol. In some implementations, the control unit 40 can transmit raw or processed data to a computer system or communication network accessible via the Internet (referred to as ‘the cloud’) that includes one or more remote computational processing devices (e.g., servers in the cloud). To support various functions of the data processing unit, the memory 48 can store information and data, such as instructions, software, values, images, and other data processed or referenced by the processor 46. For example, various types of Random Access Memory (RAM) devices, Read Only Memory (ROM) devices (e.g., including but not limited to electrically erasable programmable read-only memory (EEPROM)), Flash Memory devices, and other suitable storage media can be used to implement storage functions of the memory unit 48. The I/O 50 of the control unit 40 can interface the control unit 40 with the wireless communications unit 52 to utilize various types of wired or wireless interfaces compatible with typical data communication standards, for example, which can be used in communications of the control unit 40 with other devices via a wireless transmitter/receiver (Tx/Rx) unit, e.g., including, but not limited to, Bluetooth, Bluetooth low energy (BLE), Zigbee, IEEE 802.11, Wireless Local Area Network (WLAN), Wireless Personal Area Network (WPAN), Wireless Wide Area Network (WWAN), WiMAX, IEEE 802.16 (Worldwide Interoper-ability for Microwave Access (WiMAX)), 3G/4G/LTE cellular communication methods, NFC (Near Field Communication), and parallel interfaces. The I/O 50 of the control unit 40 can also interface with other external interfaces, sources of data storage, and/or visual or audio display devices, etc. to retrieve and transfer data and information that can be processed by the processor 46, stored in the memory unit 48, or exhibited on an output unit of the computing device 16 or an external device.
In some embodiments, the multiplexer 42 is a signal routing device having a plurality of electronic switches that are operable to control the open circuit pathways between the pickups 14 (via the pickup inputs 54) and the output 56 (e.g., amplifier and/or recording device). The MUX 42 opens and closes the pathways in response to instructions received from the processor 46, which in turn receives configuration instructions (by way of the wireless communication unit 52) from the computing device 16, as selected by the user. See, e.g.,
In some embodiments, the user may save pickup configurations as presets within the app 18, which may be selected at a later time period to save time.
By way of example, the pickups 14 are hard-wired into a terminal block 66 (e.g.
In some embodiments, the control unit 40 may be in electric communication with one or more tone controls 60a, 60b, which each comprise a tone capacitor wired in series with a tone control on the instrument. In some embodiments, by interacting with the app 18, the user is able to change the tone control capacitor values for one or both tone controls (e.g., in a dual-tone guitar). This may be accomplished by allowing a new capacitor value to be switched in series with the existing one on the instrument (e.g. cutting the capacitor value by up to about half). Additionally, the app 18 provides the user with the ability to select which tone controls 60a, 60b are active on any dual tone instrument. This gives more flexibility to the user in creating new tonalities not possible previously. By way of example, this flexibility may be in the form of (at least) four different available tone options (e.g. on a dual tone instrument) achievable by a) adjusting a single tone control on the instrument, b) adjusting both tone controls on the instrument, c) changing the tone capacitor values of one of the tone controls on the instrument using the app 18, and d) changing the tone capacitor values of both of the tone controls on the instrument using the app 18.
In some embodiments, the various electrical components described herein may be arranged on a single rigid printed circuit board (PCB) 64. In some embodiments, the various components may be arranged on two or more PCBs, including one or more rigid portions 68a, 68b (e.g., motherboard 68a and daughterboard 68b) and one or more flexible portions 69, as shown by way of example only in
In some embodiments, the PCB 64 may be arranged so that the pickup inputs 54 are located on the right side of the PCB 64 and the output connector 56, ground connector 58, tone control connectors 60a, 60b, and battery or battery connector 62 may be located on the left side of the PCB 64, with the control unit 40 and MUX 42 located in or near the middle of the PCB 64. This configuration makes the wire routing more direct and reduces crossovers. In addition, this configuration enables the tone controls 60a, 60b to be pre-harnessed and plugged directly into the PCB 64 rather than having to insert individual wires into screw terminals.
In some embodiments, the battery and/or battery connector 62 may include polarity protection, which may prevent destruction of the 3V regulator and other key active components if the user accidently hooks up the battery backwards.
In some embodiments, the rigid portions 68a, 68b may be arranged in a stacked configuration as shown by way of example only in
In some embodiments, a user may want to configure a humbucker pickup 14 having a first coil (or Coil 1) 34 off and a second coil (or Coil 2) 36 also off, as shown by way of example only in
In some embodiments, a user may want to configure a single coil pickup 14 in which the single coil 38 is off, as shown by way of example only in
In arranging the pickups initially, the user need only decide what type of pickup he or she wants to place in which part of the instrument, and then hard wire the pickups to the switch device 12 (e.g. connecting to the terminal block 66) in an initial configuration. The user may operate the switch device 12 mechanically during performances to toggle between selected sounds, as is current practice. Subsequently, if the user wants to change the phase arrangements or other configurations of the pickups 14, instead of removing the cover from the instrument and physically changing the wiring of the pickups, the user need only to access the switch management app 18 on the computing device 16, and use the user interface 70 (See, e.g.,
In some embodiments, the processor 28 converts complex wiring parameters into selectable color-coded display icons presented on the UI 70 that are designed to be simple and easy. In some embodiments, each coil (e.g., the coil of a single coil pickup, and coils 1 and 2 of a humbucker pickup) may be represented by a display icon 72 that is color-coded to visually indicate to the user the phase setting of the represented coil in the selected coil setting. By way of example, a first color (e.g., black) may be displayed to indicate that a particular coil will be off if that particular setting is selected. A second color (e.g., blue) may be displayed to indicate that a particular coil will be in phase if that particular setting is selected. A third color (e.g., red) may be displayed to indicate that a particular coil will be out of phase if that particular setting is selected. A fourth color (e.g., green) may be displayed to indicate that the two coils of a humbucker have been connected in parallel mode.
Thus, in the coil configuration shown by way of example in
In some embodiments, the first oval 101 of the example protocol 100 may represent an initial UI screen that the computer presents to the user in response to the user opening the app 18 on the user's computing device 16 (e.g. the home screen 404 of
In some embodiments, once the computer or computing device 16 has received the data from the switch device 12, the computer 16 may populate the UI 70 (Protocol box 110) with the relevant information (see, e.g., the home screen 404 of
The above-described protocol 100 represents an example set of instructions embodied in the interactive switch management app 18 that the computing device 16 implements to connect with a switch device 12, recognize the current settings of the switch device 12, receive user inputs for changes to the current settings of the switch device 12, communicate the user's instructions to the switch device 12, and confirm that the communicated instructions were implemented by the switch device 12. Some examples of user selections or automatic processes that may be included in the protocol 100 are Refresh Device 120, Disconnect 130, Bluetooth Timeout 140, Switch Reverse 150, Presets 160, Device Info 170, Pickup Settings 180, and Firmware Upgrade 190. By way of example, in nearly each case, the protocol 100 includes a quadrature check sequence.
For example, in some embodiments, the user may select a Refresh Device 120 option (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.). In response, the computer 16 sends instruction to the switch device 12 (box 122). After implementation of these instructions, the switch device 12 sends, and the computing device 16 receives, status change data confirming that the change requested by the user has been implemented (box 124). At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 24 with the new selection (e.g. by reloading the home screen 404 or start screen 400).
In some embodiments, the user may choose a Disconnect 130 selection to disconnect the computing device 16 from the previously connected switch device 12. In this case, the computer 16 may break the connection without requiring confirmation from the switch device 12.
In some embodiments, the interactive switch management app 18 may perform an automatic Bluetooth (or other wireless connection) timeout 140, for example upon expiration of a preset period of time (e.g., 30 seconds, however any duration of time may be programmed as the timeout period) during which there is no data communication between the computing device 16 and the switch device 12. Once the preset period time has expired, the computer 16 sends instruction to the switch device 12 (box 142) to sever the wireless communication (e.g. Bluetooth) connection. After implementation of these instructions, the switch device 12 sends, and the computing device 16 receives, status change data confirming that the connection is ending (box 144). At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 28 with the new status (e.g. by indicating on the home screen 404 or start screen 400 that the Bluetooth has timed out and is no longer connected).
In some embodiments, the user may select a Switch Reverse 150 option (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.), to change the assignment of pickup locations for the switch device 12. By way of example, selecting this option for a five-way switch device 12 installed on a guitar having neck, middle, and bridge pickups reverses the assignment of said pickups, for example where a particular guitar design requires that the five-way switch installation be physically reversed. In response the computer 16 sends instruction to the switch device 12 (box 152). After implementation of these instructions, the switch device 12 sends, and the computing device 16 receives, status change data confirming that the change requested by the user has been implemented (box 154). At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 28 with the new selection (e.g. by reloading the home screen 404 or start screen 400).
In some embodiments, the user may select a Presets option 160 (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.), to load a preset pickup configuration stored in the memory 30 of the computing device 16. In response, the computer 16 first retrieves the selected preset configuration and loads it into the app 18 (box 162). Then the computer 16 sends instruction to the switch device 12 to load the selected preset configuration selected by the user (box 164). After implementation of these instructions, the switch device 12 sends, and the computing device 16 receives, status change data confirming that the change requested by the user has been implemented (box 124). At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 28 with the new selection (e.g. by reloading the home screen 404 or start screen 400).
In some embodiments, the user may select a Device Info 170 option (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.). In response the computer 16 sends instruction to the switch device 12 (box 172) to check and display the device info. After implementation of these instructions, the switch device 12 sends, and the computing device 16 receives, status change data confirming that the change requested by the user has been implemented (box 174), namely, to retrieve and present information pertaining to the switch device 12 and/or stringed instrument that the switch device 12 is mounted to. At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 24 with the new selection (e.g. by reloading the home screen 404 or start screen 400).
In some embodiments, the user may select a Pickup Settings 180 option (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.), for example to change the active pickup settings on their stringed instrument. In response, the computer 16 causes the Settings page to be displayed on the display device 24 (box 182) and receives the input from the user regarding the new configuration (box 184). Next, the computer 16 may determine whether the user pressed or tapped the Save icon (box 186). If No, then the computer 16 resets to the beginning of the Pickup Settings option (box 180). If Yes, then the computer 16 sends the saved pickup configuration to the switch device 12 (box 188) for implementation. At this point, the computer 16 follows the protocol 100 to box 110 and populates the display 24 with the new selection (e.g. by reloading the home screen 404 so that it displays the new pickup configuration).
In some embodiments, the user may select a Firmware Upgrade 190 option (e.g. by tapping on an activated area of a touch screen interface or by selecting the option using a mouse, trackpad, etc.), or the app 18 may check the app store for available updates, and then upgrade automatically when appropriate. In response the computer 16 sends instruction to the switch device 12 (box 192) that an upgrade is in progress. Once the update is completed, the computer may disconnect from the device (box 194), and reset the app protocol 100 to begin at the start screen (box 101).
As shown in
If the reset button has not been pressed, or alternatively if the answer to the query of whether the boot was from wakeup was no (box 206), then the processor 46 proceeds to determine the lever 44 position (box 222), create a switch image (box 224), save the computed image to both the memory 48 (e.g. EEPROM) and real-time clock (RTC) memory (box 226) so that the switch image is accessible even if the processor 46 is on standby. The processor then loads the switch image from the memory 48 (box 228) and activates a muting feature (box 230) to eliminate any pops and clicks during the switching period, making switching totally silent. After muting has been activated, (following path B from
Once the initial pickup configuration or switch image has been implemented, the processor 46 determines whether the wakeup was triggered by the Auto Off function (box 236). If the answer is yes, then the processor 46 proceeds to clear the deep sleep reset (box 238), change the wakeup reason to flag 255 (box 240), turn off the MUX and mute (box 242), and then may reboot the system.
If the answer is no, then the processor 46 determines whether a firmware update is flagged (box 244). If the answer is yes, then the processor 46 starts the update server and clears the update flag (box 246), and then determines if the radio button (or wireless communications module 52) is on (box 248), to enable wireless communication. If the radio button is on, then the processor will cause the system to reboot (box 250) and the process begins anew. If the radio is not on, then the processor will determine whether the firmware update has been downloaded (box 252). If the answer is no, then the protocol reverts to box 248 to check that the radio is on. If the answer is yes, then the processor 46 proceeds to load the new firmware (box 254) and then performs a check to ensure the new firmware is good (box 256). If the new firmware is determined to be good, then the processor 46 proceeds to reboot the system (box 258). If the new firmware is determined to be not good, then the processor will reload the previous firmware (box 260) and reboot (box 258).
If the answer to the query of box 244 (e.g. is a firmware update flagged) is no, then the processor 46 determines whether the communications module 52 (or radio) is on (box 262). If the radio is not on, then the processor 46 forces the switch device 12 back to sleep (box 264). If the radio is on, then the processor 46 advances the protocol 200 to the main active query loop (box 266), and then proceeds to determine the lever position (box 268). Next, the processor 46 will determine whether the newly determined lever position has changed since the last determination (box 270). If the lever position has not changed, then the processor 46 again ascertains whether the radio is on (box 262) in an attempt to force the switch device 12 to sleep. If the lever position has changed since the last determination, then the processor 46 create a switch image (box 272), save the computed image to both the memory 48 (e.g. EEPROM) and real-time clock (RTC) memory (box 274) so that the switch image is accessible even if the processor 46 is on standby. The processor then loads the switch image from the memory 48 (box 276) and activates a muting feature (box 280) to eliminate any pops and clicks during the switching period, making switching totally silent. After muting has been activated, the processor 46 then sends I2C instruction (box 282) to change the open pathways through the MUX 42 to implement the pickup configuration embodied in the loaded switch image for the current lever 44 position. After the switch has concluded, the processor 46 turns the muting feature off (box 284).
Next, the processor 46 sends data to the computing device 16 via the wireless communications module 52 (e.g. via Bluetooth) to confirm that the desired switch has been made (box 286). The processor 46 then checks for incoming data from the computing device 16 (box 288). If there is no more incoming data, then the processor 46 again ascertains whether the radio is on (box 262) in an attempt to force the switch device 12 to sleep in order to conserve power.
If the answer to the query of box 288 is yes and there is more data being sent wirelessly from the computing device 16, then the processor 46 parses the data to determine the specific instructions sent (box 290), and then proceeds to implement the instructions received from the computing device 16 (box 292). For example, the instructions to be implemented may include but not be limited to saving the current pickup configuration (box 293), testing the current pickup configuration without saving (box 294), communicate the status of the switch device 12 (box 295), write the pickup kind used (box 296), provide generic memory 48 (e.g. EEPROM) access (box 297), select or indicate a switch model (box 298), turn on the firmware update (box 299), reverse the switch direction (box 300), save or write a pickup configuration as a preset configuration to the memory 48 (box 301), request the switch device 12 identification (box 302), toggle the auto-off feature (box 303), and/or determine the occurrence of a wireless connection timeout event (box 304), which would ultimately cause the processor 46 to return the device to sleep. By way of example only, each of the instructions, when implemented, may cause the processor 46 to revert the protocol 200 to various relevant points in the main loop (e.g., box 266 and thereafter).
By way of example only, the example sleep protocol 310 provided herein begins upon movement of the lever 44, which causes the processor 46 of the switch device 12 to “wake up” (box 312). The first thing the processor 46 does is to determine whether the wakeup source=255 (box 314), which if yes requires a system reboot (box 316). If no, then the processor 46 feeds the auto off timer (box 318) and determines the time from the last strum increment (box 320). If the time from the last strum increment is greater than 3 seconds, then the processor sets the strum counter to 0 (box 322) and determines the lever position (box 324). If the lever position is determined to be in one of the end positions of the multi-position switch 12 (e.g., position 1 or 5 of a 5-way switch as described by way of example only herein throughout) (box 326), then the processor 46 will activate the increment strum counter (box 328). If the strum counter is greater than 3 (box 330), then the processor 46 will determine if the strum counter incremented within the last 3 seconds (box 332). If the time from the last strum increment is less than 3 seconds, then the protocol proceeds to the system bootup protocol by setting up registers (box 202,
By way of example, if the lever position is determined to be in a non-end position of the multi-position switch 12 (e.g., positions 2, 3, or 4 of a 5-way switch)(box 326), or if the lever position is in an end position and after the strum counter has been set to 0 (box 332), the processor 46 loads the switch image corresponding to the lever position from the memory 48 (box 336) and activates a muting feature (box 338) to eliminate any pops and clicks during the switching period, making switching totally silent. After muting has been activated, the processor 46 then sends I2C instruction (box 340) to change the open pathways through the MUX 42 to implement the pickup configuration embodied in the loaded switch image for the current lever 44 position. After the switch has concluded, the processor 46 turns the muting feature off (box 342).
By way of example, after the pickup configuration has been set, the processor determines whether the wakeup was triggered by the Auto Off function (box 344,
In some embodiments, wiping the lever 44 back and forth through two or more cycles may activate the wireless communication module (e.g., turn on the Bluetooth radio, for example). If nothing else happens in a set period of time (e.g., 30 seconds), for example if the user somehow accidentally activated this feature, then the wireless communication module will turn off the communication radio to conserve power. This feature is advantageous in that it reduces the number of parts and materials to be placed into the instrument cavity, thereby reducing bulky wiring issues and also reduces the costs associated with the system.
By way of example, the computer may present a first-time user with a signup screen, where the user may create an account using one of email, phone number, Google ID, Facebook ID, or Apple ID, and by choosing a password. Upon entering these credentials, the computer may present the user with a set of Terms & Conditions, which the user must agree to before their account is activated. Once the user agrees to the Terms & Conditions, the computer may present the user with a password verification screen, in which the user enters their chosen password. If the entered password matches the registered password, then the computer advances the user to the next screen, which may be an optional Profile Completion screen. By way of example only, in this screen the user may be able to enter their name and attach a photo, among other things. Once the user has completed the profile (or skipped the opportunity), the computer may prompt the user to wirelessly connect their switch device 12, for example using Bluetooth or similar wireless data transfer technology.
By way of example, a registered but logged out user may be presented with a login screen, which may include a name field for the user to input their name, username, email address, Facebook ID, Google ID, or Apple ID, and a password field for the user to input their password to gain access to the software. The computer verifies the authentication data against a list of registered users and if the authentication data matches, the computer advances the user to the next screen.
Once the user has successfully created an account and/or logged into the interactive switch management app 18, he or she is directed to the home screen 404 (e.g.
By way of example, if the user wants to change the configuration of one or more pickups 14 (e.g. to change the sound produced by the stringed instrument) for any lever position, the user may select or tap the corresponding pickup configuration icon 72a, 72b, 72c, which by way of example only causes a the computer 16 to shift the pickup configuration to the next configuration on the right on the status indicator bar 86. For example, tapping on pickup icon 72b would cause the computer 16 to change the corresponding pickup indicator 86 from “standard” to “reverse” since “reverse” is one step to the right of “standard”. Tapping on the pickup icon 72b a second time (or twice in succession) causes the computer 16 to change the pickup configuration to “off”, and so forth. In some embodiments, pressing and holding one's finger on the tappable icon causes the computer 16 to display a pickup menu 406 with the configuration options (e.g. standard, reverse, parallel, off) for that particular pickup at the selected lever position (See, e.g.
By way of example only, the computer may display additional display icons (which may be interactive) on the user interface 70, including but not limited to a menu icon 78, which when tapped or otherwise activated by a user causes the computer to present the user with a popup menu, as shown for example in
By way of example only,

In some embodiments, clicking or tapping on the “Device Settings” option 444 causes the computer 16 to present the user with a variety of options to configure the switch device 12. In some embodiments, clicking or tapping on the “Application Settings” option 446 causes the computer 16 to present the user with a variety of options to configure the app 18, including but not limited to updating or resetting the user's password, instructing the processor 24 to check for available updates to the app 18, toggling notifications on or off, toggling sleep mode on or off, and troubleshooting options. In some embodiments, tapping or clicking on the “My Account” option 448 causes the computer 16 to present the user with a variety of options to change information associated with the user's account including but not limited to (and by way of example only) the user's name, nickname, photo, email address, social media IDs, and the like. In some embodiments, tapping or clicking on the “Tutorials” option 450 causes the computer 16 to present the user with a variety of tutorial options that the user can explore to become familiar with using the app 18 and/or switch device 12.
In some embodiments, tapping or clicking on the “Load A Preset” option 452 causes the computer 16 to present the user with a list of the user's previously saved preset pickup configurations. The user may then tap or click on one of these presets to load into the home screen 404 for a particular lever position. In some embodiments, tapping or clicking on the “Save My Preset” option 454 may save a pickup configuration to the list of presets, much like tapping or clicking on the “Save Preset” button 92 of the home screen 404.
In some embodiments, tapping or clicking on the “Device Info” option 456 causes the computer 16 to present the user with information concerning the connected switch device 12, as well as any other devices that have been saved within the app 18. In some embodiments, tapping or clicking on the “Firmware Upgrade” option 458 causes the computer 16 to check for available firmware upgrades, and to initiate the upgrade process if found. In some embodiments, the “Factory Reset” option 460 causes the computer 16 to reset the app 18 and/or the firmware stored on the switch device 12 to the original configurations as received from the factory. This allows the users to experiment with various sound configurations without having to worry about permanently “ruining” their instrument or product. The “Factory Reset” options 460 provides an option of simply starting over.
In some embodiments, the switching system 10 of the present disclosure may use a proprietary serial communication protocol with a dynamic byte length and a closed loop check to ensure data consistency.
In some embodiments, the switching system 10 of the present disclosure implements a true analog signal path without bypass capacitor or bias resistor in the signal path to ensure a wide frequency response and preserve the signal phase. This removes even unwanted capacitive loads.
In some embodiments, the switching system of the present disclosure may capture, record, and/or otherwise use lever position information (e.g. for electric guitars) information of other sensors that may be present on the instrument or the switching system itself (e.g., potentiometers, accelerometers, position sensors, buttons, etc.), and/or the analog sound streams that may be present on the instrument, and transmit the captured, recorded, or otherwise used data to the user's computing device or other computing systems, for example to control other peripheral wireless-enabled devices using a MIDI protocol or any other serial protocol.

The memory 504 stores information within the computing device 500. By way of example only, the memory 504 may be a volatile memory unit, non-volatile memory unit, or another form of computer-readable medium, such as a magnetic or optical disk (for example).
The storage device 506 is capable of providing mass storage for the computing device 500. In one implementation, the storage device 506 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. A computer program product can be tangibly embodied in an information carrier. The computer program product may also contain instructions that, when executed, perform one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory 504, the storage device 506, or memory on processor 502.
The high-speed interface 508 manages bandwidth-intensive operations for the computing device 500, while the low speed interface 512 manages lower bandwidth-intensive operations. Such allocation of functions is by way of example only. In one implementation, the high-speed interface 508 is coupled to memory 504, display 516 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 510, which may accept various expansion cards (not shown). In the implementation, low-speed interface 512 is coupled to storage device 506 and low-speed expansion port 514. The low-speed expansion port may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet) and may be coupled to one or more input/output devices, such as a keyboard 518, a printer 520, a scanner 522, or a networking device such as a switch or router 524, e.g., through a network adapter.
The computing device 500 may be implemented in a number of different forms. For example, it may be implemented as a standard server, or multiple times in a group of such servers. It may also be implemented as part of a rack server system. In addition, it may be implemented in a personal computer such as a laptop computer. Alternatively, components from computing device 500 may be combined with other components in a mobile device, such as device 550 (

The processor 552 can execute instructions within the computing device 550, including instructions stored in the memory 554. The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. Additionally, the processor may be implemented using any of a number of architectures. For example, the processor 552 may be a CISC (Complex Instruction Set Computers) processor, a RISC (Reduced Instruction Set Computer) processor, or a MISC (Minimal Instruction Set Computer) processor. The processor may provide, for example, for coordination of the other components of the device 550, such as control of user interfaces, applications run by device 550, and wireless communication by device 550.
The processor 552 may communicate with a user through control interface 562 and display interface 564 coupled to a display 556. The display 556 may be, for example, a TFT (Thin-Film-Transistor Liquid Crystal Display) display or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface 564 may comprise appropriate circuitry for driving the display 556 to present graphical and other information to a user. The control interface 562 may receive commands from a user and convert them for submission to the processor 552. In addition, an external interface 566 may be provided in communication with processor 552, so as to enable near area communication of device 550 with other devices. External interface 566 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.
The memory 554 stores information within the computing device 550. The memory 554 can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. Expansion memory 568 may also be provided and connected to device 550 through expansion interface 570, which may include, for example, a SIMM (Single In Line Memory Module) card interface. Such expansion memory 568 may provide extra storage space for device 550, or may also store applications or other information for device 550. Specifically, expansion memory 568 may include instructions to carry out or supplement the processes described above and may include secure information also. Thus, for example, expansion memory 568 may be provided as a security module for device 550, and may be programmed with instructions that permit secure use of device 550. In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner.
The memory may include, for example, flash memory and/or NVRAM memory, as discussed below. In one implementation, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, cause performance of one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory 554, expansion memory 568, or memory on processor 552 that may be received, for example, over transceiver 560 or external interface 566.
Device 550 may communicate wirelessly through communication interface 558, which may include digital signal processing circuitry where necessary. Communication interface 558 may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver 560. In addition, short-range communication may occur, such as using a Bluetooth, WiFi, or other such transceiver (not shown). In addition, GPS (Global Positioning System) receiver module 572 may provide additional navigation- and location-related wireless data to device 550, which may be used as appropriate by applications running on device 550.
Device 550 may also communicate audibly using audio codec 574, which may receive spoken information from a user and convert it to usable digital information. Audio codec 574 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of device 550. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on device 550.
The computing device 550 may be implemented in a number of different forms, some of which are shown in the figure. For example, it may be implemented as a cellular telephone. It may also be implemented as part of a smart-phone, personal digital assistant, or other similar mobile device.
Additionally computing device 500 or 550 can include Universal Serial Bus (USB) flash drives. The USB flash drives may store operating systems and other applications. The USB flash drives can include input/output components, such as a wireless transmitter or USB connector that may be inserted into a USB port of another computing device.
Various implementations of the systems and techniques described here can be realized in digital electronic circuitry, integrated circuitry, specially designed ASICs (application specific integrated circuits), computer hardware, firmware, software, and/or combinations thereof. These various implementations can include implementation in one or more computer programs that are executable and/or interpretable on a programmable system including at least one programmable processor, which may be special or general purpose, coupled to receive data and instructions from, and to transmit data and instructions to, a storage system, at least one input device, and at least one output device.
These computer programs (also known as programs, software, software applications or code) include machine instructions for a programmable processor and can be implemented in a high-level procedural and/or object-oriented programming language, and/or in assembly/machine language. As used herein, the terms “machine-readable medium” and “computer-readable medium” refer to any computer program product, apparatus and/or device (e.g., magnetic discs, optical disks, memory, Programmable Logic Devices (PLDs)) used to provide machine instructions and/or data to a programmable processor.
To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a back end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front end component (e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), peer-to-peer networks (having ad-hoc or static members), grid computing infrastructures, and the Internet.
The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network.
Any of the features or attributes of the above described embodiments and variations can be used in combination with any of the other features and attributes of the above described embodiments and variations as desired.
