Title:
MUSICAL SOUND SYNTHESIZING DEVICE
Document Type and Number:
Japanese Patent JP3404756
Kind Code:
B2
Abstract:
PURPOSE: To provide the musical sound synthesizing device which express timbre like a fixed formant.
CONSTITUTION: This musical sound synthesizing device is provided with a waveform memory 6 stored with the waveform data of plural cycles which have a waveform value '0' at the start point and end point of each cycle and are marked at the start point of each cycle, address generators 61a-61d which generate multi-layered phase data varying at a constant rate to values corresponding to the end point from a value corresponding to the start point of each cycle by giving mutual delay by a time corresponding to pitch to be sounded, reads waveform data of one cycle starting with the marked waveform data out of the waveform memory 6 in parallel according to phase data corresponding to the respective phases, and reads out the waveform data of a cycle following the cycle read yet in response to the supply of the phase data corresponding to the start point of the cycle, and an accumulator 75 which adds and outputs the waveform values of the respective read waveform data and outputs a waveform value of an amplitude '0' in a period wherein the waveform data are not read out.
