ABSTRACT:
In response to the data input from a keyboard, a tone clock generator generates a tone clock signal. The tone clock signal is counted by a waveform step counter. The output of the counter is used for making an access to a waveform memory. The waveform memory stores first and second waveform data of which the periods respectively are divided into a different number of addresses. One of the first and second waveform data read out from the waveform memory by the output of the counter is selected, according to the key-in data.
