Abstract
A morphing method and an apparatus for creating musical accompaniments from a combination of musical data selected from stored patterns or tables belonging to accompaniments of different musical styles. Musical data relating to a pattern of a first style and musical data relating to a second style, as well as the desired combination of morphing degree are selected from a plurality of stored data patterns. The musical morphing of the new arrangement is created by conjointly reading in real time one or more data tracks of two or more selected patterns, relating to different families of musical instruments, and combining the read tracks in a new virtual pattern that can be stored and/or played in a musically significant manner, by making the musical measures and the temporal lengths of the tracks of the new pattern, conform with the musical measures and temporal lengths of the tracks relating to one of the patterns selected or creating the new musical arrangement.
Description
BACKGROUND OF THE INVENTION
The invention relates to a method and an electronic apparatus for the creation of new arrangement of melodic and/or rhythmic parts of musical accompaniments from patterns of different styles and namely by transforming the musical morphology of at least a first style into a second style according to a pre-programmed scheme of data replacement and degree, in order to obtain one or more new intermediate styles by means of a musical procedure hereafter referred to as musical “style morphing”. For the purpose of the present invention “musical morphing” means the construction of a new arrangement or pattern of an intermediate style, by an appropriate combination of musical data pertaining to different tracks of base patterns relating to two or more base arrangements of different styles, while the morphing degree depends from the number and/or type of tracks of the base patterns combined in the new pattern of new or intermediate style.
This invention represents an improvement of the electronic apparatus for the automatic composition and reproduction of musical data, of a previous patent U.S. Pat. No. 5,679,913, which is regarded as an incorporated part of the present description, although some useful parts thereof will be resumed to better describe the present invention.
PRIOR ART
As it has already been reported in the previous patent U.S. Pat. No. 5,679,913, in an electronic musical instrument which uses an automatic apparatus capable of recording and reproducing data, the various musical pieces, being either “patterns” or tables relating to accompaniments of different musical styles, are generally written in digital form and memorized on several tracks to be subsequently reproduced in such a way that a performer is able to control them in an interactive manner and in real time.
At present, “arrangers” or similar apparatuses capable of recording and reproducing accompaniments relating to various musical styles, which can be combined together during the execution thereof, make use of a data recording and reproducing method that is substantially based on multi-track system, in which the lengths of individual tracks must be identical to one another and must be a whole multiple of a “bar” or of a same musical measure; moreover, also the “time signature” must be identical for the tracks relating to the various instrument families of each data pattern to be recorded and/or reproduced.
Therefore, with the currently known apparatuses, it is not possible to create accompaniments of different styles by collecting data from tracks having different lengths and/or time signature because, otherwise, it would not be possible to obtain a musically consistent synchronization when reading the various tracks. Systems of this kind are described, for example, in U.S. Pat. No. 4,685,370.
From a subsequent patent U.S. Pat. No. 5,457,282, an automatic accompaniment apparatus is also known, by which a plurality of original accompaniment patterns, relating to various styles, may be used to compose new patterns or new arrangements by collecting together the desired pattern parts which may be combined to create a new accompaniment.
This patent U.S. Pat. No. 5,457,282 merely proposes a different system for composing accompaniment patterns, without providing the performer with any possibility of selecting musical pieces or parts thereof among the several groups of track relating to the available accompaniment patterns, or of modifying the “style” of a song and/or accompaniment in its rhythmic part in real time, while maintaining a synchronized and musically consistent performance.
The apparatus described in the previous patent U.S. Pat. No. 5,679,913 tackled this problem and the present invention stands for an improvement thereof. This patent proposes an electronic apparatus for the composition and reproduction of musical data codified in numerical form, by means of which the performer is able to freely compose and reproduce pre-stored musical patterns or patterns provided on purpose by the same performer, or by using accompaniment patterns of different styles, which can be selected, combined and reproduced in real time in a musically significant manner while being automatically performed.
The previous patent U.S. Pat. No. 5,679,913, to which the present invention is referred, describes only the technical means to carry out a style modification in a universal manner; practically the previous patent makes a transformation process possible between two styles, which are different and are not similar (for example, having different time signatures—3/4, 4/4—and different measures). In the previous patent, moreover, the possibility is described to exchange tracks between two styles without mentioning at all the consistence of the musical result, unless such operation is made by an expert musician (“collage”).
OBJECTS OF THE INVENTION
The general object of the invention is to provide a method for creating new musical styles and, in particular, new arrangements of melodic and/or rhythmic pats of musical accompaniments on the basis of pre-stored base styles, and by going through one or more musical morphing steps, which make it possible to migrate from at least one style into another one in a musically consistent and significant manner, so as to obtain a remarkable higher number of automatic accompaniments than the pre-stored ones, while keeping a same original memory size of an electronic musical apparatus. This way, new intermediate arrangements can be created between two styles, by gradually and selectively moving, through subsequent morphing steps, from a musical arrangement of a first base style into an arrangement of a second base style.
Another object of the invention is to provide a method as described above, by which it is possible to automatically change the morphing degree during the transition from a first current style into a second style, according to a pre-determined substitution or combination scheme for the musical data that can be changed by a performer each time.
Another object of the invention is to provide a method for creating arrangements of new musical styles, by suitably combining musical data of two or more musical patterns of different styles, to generate a new virtual pattern that can be stored and/or played in a musically consistent manner.
Yet another object of the invention is to provide an apparatus for creating musical arrangements by morphing musical accompaniments of different styles according to the method referred to above, such apparatus being an integral part of an electronic musical instrument.

DETAILED DESCRIPTION OF THE INVENTION
The general features of the electronic apparatus for the creation of musical arrangements by morphing different base styles according to the invention, will be now described by making reference to the
FIGS. 1 and 2
.
As shown in
FIG. 1
, the apparatus comprises several functional blocks connected with a data processing and control unit
10
, such as a CPU, which includes a block
11
comprising a reader having a number of pointers for reading out data tracks and information contained in the other functional blocks of the apparatus.
In addition to the block
11
for pointing and reading the data contained in the tracks of the several musical base patterns relating to the various musical styles that are already stored in a memory unit, the apparatus comprises a first ROM memory
14
, namely a read-only memory, in which patterns of musical data for a plurality of accompaniments relating to different musical base styles have been stored, whereby such data can be either read directly by the ROM memory
14
or transferred into a RAM memory
15
, a random access memory, for their composition.
The apparatus comprises also a pattern selecting block
12
including some buttons for selecting pre-stored patterns relating to the various musical styles, this block
12
being associated with a control panel
13
, which is provided with the necessary switches to start the different functions and select the parameter values in a completely usual manner.
As shown in
FIG. 2
, the control panel
13
is also provided with two buttons, A and B, to assign the pre-stored patterns relating to the various accompaniment base styles; by means of these two buttons several functions can be activated like, for example, that assigning automatically two accompaniment styles (style A, style B) whose musical data can be exchanged by morphing the homologous tracks of the selected patterns, or that defining the morphing degree depending on the type and number of homologous tracks to be replaced when changing from one style into the other, or that allowing the performer to freely choose the styles whose musical data have to be morphed by transferring the homologous tracks of the patterns belonging to different styles that the performer could even freely program in the RAM memory
15
, as it will be explained further on.
Beside the A and B buttons for the style assignment and the selection of the morphing degrees of musical patterns belonging to different styles, the control panel
13
includes also a display
16
, on which indications about the selected base styles appear as well as some lit graphic representations showing the selected morphing degree, that comprise a number of lit bars,
17
A and
17
B, divided into two rows, one close to the other and each one in relation with the corresponding button, A or B; the lit graphic bar rows,
17
A and
17
B, are hence meant to visually indicate the various degrees of either transformation or approximation by musically morphing the style A into the style B, and vice versa, as it is schematically represented in the
FIGS. 3 through 10
of the enclosed drawings and in the table shown further ahead.
The patterns of musical data relating to the several accompaniment base styles, that have been either pre-stored by the manufacturer in the ROM memory
14
, or freely created by a performed in the RAM memory
15
, can be read by an external device by means of a MIDI OUT serial port, referred to as
18
, by sending adequate control signals or by means of a MIDI IN serial port, referred to as
19
, which receives musical data coming from external control devices or sources, like for instance, a musical keyboard, a floppy disk and the like.
In addition, the apparatus comprises some counters, C, D and E, for counting the clock pulses emitted by a pulse generator inside the block
20
, which are intended to perform various functions; more precisely it comprises a counter C, which counts the clock pulses used to determine the distance between two successive musical events in each track of a musical pattern; this counter, in practice, at the speed set by the clock signals, decreases the value of the number of the clock or CPT signals of the data patterns contained in the memories
14
and
15
, read by the reading block
11
, when the counting down reaches the value zero. Furthermore, the apparatus comprises a counter D for counting the clock pulses used to determine the distance of the musical event read first in a bar, from the start point of the next musical bar, as well as a third counter E for counting the clock pulses used to synchronize the readings of the various data patterns that are selected dynamically. All this matter is explained in greater detail, with specific reference, in the previously mentioned patent U.S. Pat. No. 5,679,913.
As previously mentioned, the ROM memory
14
contains a plurality of musical patterns in a separate area, whereby each of these patterns comprises a set of parallel tracks including the musical data relating to the various instrument families, which make up that particular musical accompaniment style.
Beside the memory means
14
and
15
, the CPU
10
is also provided with program means including program instructions, that in a pre-defined manner, are capable of selecting and combining every musical pattern of one base style with the musical patterns of a different base style, such patterns being similar with one another and being chosen among a plurality of musical patterns by using appropriate selection means, namely either the buttons A or B on the control panel or any other adequate means.
Beside the instructions for selecting and combining patterns of styles that are different but musically similar, the programming means, including the ROM memory, contain program instructions for selecting the musical morphing degree, that results from subsequent replacements of one or more musically homologous tracks between data patterns relating to the style A, and data patterns relating to the style B.
A replacement of a different type and number of tracks in a manner that is either pre-determined by the manufacturer in the ROM memory or programmed by the end user in the RAM memory, corresponds with each morphing degree.
The above will be clarified in more detail herein below with reference to the remaining
FIGS. 11
to
18
of the enclosed drawings, in which different musical morphing degrees have been depicted between two patterns A and B each having eight homologous tracks pertaining to different musical families.
According to a particular aspect of the invention it is possible to provide the program means with the instructions necessary to set different morphing degrees for each pair of selected patterns. For example, taking the following indications into consideration:
ADR stands for the track related to drums;
ABS stands for the track related to bass;
AC
1
-AC
6
stand for the tracks relating to the various instrument families of orchestral accompaniments.
Considering also that the apparatus is capable of reading the ADR and ABS tracks individually and of reading all the tracks from AC
1
through AC
6
simultaneously or just some of them, the six different morphing degrees shown in the table below are made possible:

In the above table, the first column shows the various morphing degrees, the second column shows the musical tracks of the pattern A, the third column shows the musical tracks of the pattern B that are read in substitution of the homologous tracks belonging to the pattern A, while the fourth column shows the FIGS. from
3
through
10
that appear as lit graphic representations providing an immediate overview of the morphing degree obtained during the transition from the base style A into the base style B and vice versa.
Of course, other morphing degrees can be provided by combining the reading sequence of the tracks in a different manner; it is also possible for the user, by means of the buttons A and B and of proper program means, to select patterns of styles that are different from the pre-determined ones, changing the morphing degrees and types and taking his own choices.
The method for musical morphing between different styles according to the present invention can be clarified more in detail by referring to a specific example like that shown in the FIGS. from
11
through
18
, that represent the various morphing degrees that are possible when transforming a base style A into a base style B.
The various figures shown the base pattern of the style A with its corresponding tracks of musical data, the base pattern of the style B with its corresponding musical tracks, as well as the new pattern of the style AB that is virtually obtained by morphing the two previous patterns. Between the two patterns of the styles A and B and the combined patterns of the style AB, there is a grill diagram indicating the various combinations that have been pre-determined by the manufacturer, wherein the black dots stand for the various logical switches under the condition in which the reading pointers are activated for each of the tracks, namely the current reading locations and addresses for each track to obtain the desired morphing degree, during the transition from the style A into the style B and vice versa.
In particular,
FIG. 11
represents the morphing degree 0, in which the style AB fully corresponds with the style A; this condition is also shown by the lit graphic representation of FIG.
3
.
FIG. 12
represents the morphing degree 1, in which the style AB is obtained by combining the track ADR of the style B, that replaces the homologous ADR track in the style A, with the remaining tracks in the style A (ABS, AC
1
through AC
2
); this condition is also shown by the lit graphic representation of FIG.
4
.
FIG. 13
represents the morphing degree 2, in which the ABS track in the style B is combined with the ADR and AC
1
˜AC
6
tracks in the style A, and replaces the homologous ABS track in the style B; this condition is also shown by the lit graphic representation of FIG.
5
.
FIG. 14
represents the morphing degree 3 indicated in the above table, in which the tracks from AC
1
to AC
6
in the style B are combined or read simultaneously with the ADR and ABS tracks in the style A, thus obtaining the style AB; this condition is also shown by the lit graphic representation of FIG.
6
.
As indicated in the above mentioned table, the following figures shown the remaining morphing degrees between the style A and the style B in a similar way.
According to a possible variant of the method compliant with the present invention, by means of a special control button the user can save at least one musical pattern, resulting from morphing different styles with the desired morphing degree, in the RAM memory of the apparatus so as to be able to have it immediately available to use later on.
So, according to the present invention, thanks to the replacement of homologous tracks (bass with bass, drums with drums, orchestral instruments with other similar ones, etc.) it is practically assured that a consistent, anyway creative and pleasant musical result can be obtained, even though such operation is carried out by a beginner musician. This is all the more true according to this typical application, wherein when a style A is chosen, it is automatically coupled with a style B, that is musically similar to the former, for example under the point of view of musical tempo, performing speed, style family. Furthermore, it is to clarify that if the user wishes to choose a style B other than the pre-set one, the user just has to keep the B button pressed and simultaneously press a different style within the “Pattern selection” section in the control panel.
In the previous examples of
FIGS. 11
to
18
, a method has been described for creating arrangements of melodic and/or rhythmic parts of musical accompaniments by musically morphing between two patterns of different styles. As previously stated the musical morphing between the patterns A and B, is obtained by conjointly reading a number of data tracks pertaining to different musical families of a first pattern (either A or B), and a number of homologous data tracks pertaining to different musical families of the other pattern (either A or B), corresponding to the remaining data tracks, of said first pattern; to this purpose, the reader of the reading block
11
should be provided with a corresponding number of pointers for reading the maximum number of tracks allowed or comprised in the base patterns stored in the apparatus.
According to the present invention morphing is also possible among more than two musical patterns having a same or different number of data tracks, by using the same morphing procedure.
More precisely, in the event that the musical morphing should be performed among three or more base patterns having a same or different number of musical tracks, according to the invention it is possible to select different data tracks from each of the patterns and conjointly reading-out or combining, in a consistent musical manner, the selected tracks of the involved patterns to create a virtual new pattern in which each data track comprises the musical data of a homologous data track of one of the base patterns, still making uniform the musical measures and temporal lengths of all selected data tracks.
