Abstract
In an electronic musical instrument of a keyboard type wherein waveshapes with different tone colors read out from waveshape memories are mixed together at a mixing ratio according to a control signal and the resultant signal is converted to a corresponding musical tone, the control signal is varied with lapse of time and also is controllable in response to the initial speed at which a key of the keyboard is depressed and to the strength of pressure of the key being depressed, in addition to time lapse. Thus, the pattern of tone variation can be variously controlled.
