Abstract
An electronic musical instrument of a waveshape memory type comprising: a plurality of waveshape memories for storing waveshapes of different tone color, and means for variably mixing the outputs of the plurality of waveshape memories for generating tone signals of varying tone color. The mixing ratio of the different waveshapes may be varied with the lapse of time or according to the touch of the key operation or to the tone pitch.

An electronic musical instrument of a waveshape memory type comprising:
- a plurality of waveshape memories for storing waveshapes of different tone colors and reproducing waveshape signals of said different tone colors;
- means for mixing the waveshape signals from said plurality of waveshape memories;
- means for controlling the mixing ratio of said waveshape signals, and in which
- said control means includes a function-of-time generator for generating a function-of-time signal, arithmetic means for achieving different arithmetic operations on said waveshape signals with said function-of-time signal to produce varying partial tone signals of said different tone colors and said mixing means is an adder for adding said varying partial tone signals.
An electronic musical instrument of a waveshape memory type comprising:
- a plurality of waveshape memories for storing waveshapes of different tone colors and reproducing waveshape signals of said different tone colors;
- means for mixing the waveshape signals from said plurality of waveshape memories;
- means for controlling the mixing ratio of said waveshape signals, and in which
- said electronic musical instrument includes a keyboard and said control means includes a touch-responsive signal generator for generating a touch-responsive signal having a level responsive to the touch of key depression in the keyboard and arithmetic means for achieving different arithmetic operations on said waveshape signals using said touch-responsive signal.
An electronic musical instrument of a waveshape memory type, comprising:
- a plurality of waveshape memories for storing waveshape of different tone colors;
- means for variably mixing the outputs of said plurality of waveshape memories for generating tone signals of varying tone color, and in which
- said instrument is a keyboard musical instrument having keys for playing tones and the mixing ratio of the outputs of said plurality of waveshape memories is varied with the touch of said keys.
