PURPOSE: To make processing timing between each processing system close and to enable omitting a register for delaying data. CONSTITUTION: P data out of LFO output outputted from an envelop generator 24 is given to an address generator 22, and an address for reading a waveform memory 8 is made by synthesizing with pitch information. F data of the LFO output is synthesized with FE data of an EG output, and is used as a filter coefficient at the time of filter operation processing of a waveform operation section 23. A data of the LFO output is synthesized with the other parameter by level synthesizing operation, and used at the time of ch-cumulative total processing. Compressed waveform data read out by the made address is expanded by a decoder, but interpolation processing can be performed with the prescribed timing in the waveform operation section 23 by using a register in the decoder as a delay means. |
