Abstract
An electronic musical instrument comprising first and second musical tone signal synthesizing circuit arrangements including voltage waveform generators adapted to control first and second tone signals to be generated by the first and second musical tone signal synthesizing circuit arrangements. First and second memory groups including a plurality of waveform parameter controlling information memories are provided for control of the voltage waveform generators in the first and second musical tone signal synthesizing circuit arrangements. A memory selector includes the same number of preset switches as that of the memories in each of the first and second memory groups. When two preset switches are actuated, one corresponding memory in the first memory group and the other corresponding memory in the second memory group are selectively enabled according to a preselected preference order to couple waveform parameter controlling information to the first and second musical tone signal synthesizing circuit arrangements.
