SIGNAL GENERATION METHOD, SIGNAL GENERATION SYSTEM, ELECTRONIC MUSICAL INSTRUMENT AND PROGRAM

To generate acoustic signals with various acoustic characteristics in response to operations by a user with simple processing.SOLUTION: A signal generation system 30 comprises: a signal generation unit 72 that generates acoustic signals V in response to operations on a plurality of keys including a first key and a second key; and an operation control unit 73 that controls generation of the acoustic signals V in response to a reference position, which is a position of the first key at a time point of the operation on the second key, when the second key is operated during the operation on the first key.SELECTED DRAWING: Figure 4 【課題】利用者による操作に応じた多様な音響特性の音響信号を、簡便な処理により生成する。【解決手段】信号生成システム３０は、第１鍵と第２鍵とを含む複数の鍵に対する操作に応じた音響信号Ｖを生成する信号生成部７２と、第１鍵の操作中に第２鍵が操作された場合に、第２鍵に対する操作の時点における第１鍵の位置である参照位置に応じて、音響信号Ｖの生成を制御する動作制御部７３とを具備する。【選択図】図４
