Tone signal generation device

摘要

A waveshape memory stores waveshape data representing plural waveshapes each having plural periods. A reading sequence controller designates ones to be read out among said waveshape data from the waveshape memory and the readout order thereof. This order may either be a random order or a predetermined one. By performing the readout of the waveshape data, repetitive reading of the same waveshape data is basically avoided, and a periodical noise and monotonousness in the tone color which tend to arise from such repetitive reading are eliminated.
