Claims
- 1. An electronic musical instrument having a plurality of keyboards each with keys for playing notes having note names, comprising:
- a frequency number memory (190) for storing a frequency number for each note name of each key and a frequency number for modulation for each note name for providing at least one of a vibrato and a glide effect;
- frequency modulated data generating means (100, 110) for selectively generating one of glide and vibrato data;
- a key assignor (140) for generating key depression information and keyboard information;
- the frequency number memory storing therein the frequency number for each note at an address using the key depression information as a function and the frequency number for modulation for each note name at an address using, as functions, frequency modulated data from the frequency modulated data generating means (100, 110) and the key depression information, the frequency number memory additionally storing therein the frequency number corresponding to each note name at an address using the key depression information and the keyboard information as functions;
- an address signal for the frequency number memory being divided into a high-order address (L8) by high-order bits and a low-order address (L6) by low-order bits;
- means (180, 130) for addressing the high-order address by the key depression information and the low-order address by the frequency modulated data; and
- a data converter (15) connected in a signal path of the low-order address (16) for converting the output of the frequency modulated data generating means (100, 110) in relation to the keyboard information, the converted output being used as the low-order address of the frequency number memory (190).
- 2. An electronic musical instrument according to claim 1, wherein an adder (200) is provided in a path of the address signal for the frequency number memory for adding a pitch control signal to the address signal, the output of the adder being used as a new address signal for the frequency number memory.
