PURPOSE:To reflect user's will on the effect giving mode in real time by controlling the feedback level of the output of an effector by the controlled variable of a performance operator. CONSTITUTION:In the case of giving of a delay effect, two delay effect giving parts are provided for two effects independently of each other, and two delay circuits 71 are provided. Waveform data are delayed by delay time parameters DRTIME and DLTIME and are read out from delay circuits 71, and the outputs are multiplied in multipliers 72 on the feedback by repeat parameters DRRPT and DLRPT and are added to input signals by adders 73, and results are inputted to delay circuits 71. The outputs are multiplied in multipliers 74 by parameters DRDPTH and DLDPTH, which determine the depth of delay, and are added to input signals by adders 75 to obtain the outputs. That is, input signals are delayed by delay circuits 71 having feedback loops and are added to input signals again, and thus, delay effects are given. |
