Abstract

PURPOSE: To produce the musical tone changing in voice surely with time by addressing waveform memories by touched key pitch signals and selecting and multiplying the weights abruptly changing with the time of parameter memories.
CONSTITUTION: The code signals corresponding to touched key pitches by a frequency memory 2 and cumulator 3 become address signals, by which the waveform signals are read out from waveform memories 4, 5. In addition, accoding to the outputs of a comparator 9 to which reference values are applied, selectors 10, 11 select and generate the weight signals changing abruptly with time outputted by weight parameter memories 12 and 14, 13 and 15 respectvely. Then, multipliers 6, 7 multiply the respective waveform signals by different weights in the front and last halves of the one period of the waveforms and even when the touched key pitches are low, the musical tone waveform signals of the waveforms surely changing with time are produced from an adder 29. Hence, the musical tone resembling to that of natural musical instruments of surely changing timers with time may be produced.
