Abstract

PURPOSE: To effectively utilize a waveform memory and obtain many sound source waveforms which are rich in variation by optionally setting the start address and end address of each loop section and the read order of loop sections. CONSTITUTION: This musical instrument is equipped with a means which selects plural data sections out of a series of waveform data stored in a waveform information storage means and sets their start addresses and end addresses and the read order of the sections and a means which reads stored waveform data out according to the set order. For example, a current address register 1, a pitch data register 2, a loop start address register 3, an offset data register 4, a loop end address register 5, and a cross-fade level register 17 are each of 8-stage constitution. Consequently, plural loop sections are selected out of a waveform from the waveform information storage means, and a user can optionally set the start address and end address of each loop section and the read order of the respective loop sections.
