PURPOSE:To make it possible to apply prescribed delay time to plural sound sources even if these sound sources are not discretely provided with delay circuits without impairing a location feel by providing this controller with delay lines which successively delay the musical tone signals of respective systems. CONSTITUTION:An adder A1 adds the musical tone signal from a sound source circuit A and an initial value 0. Adders A3, A5 respectively add the signals from sound source circuits B, C and delay circuits D13, D35. Delay circuits D13, D35, D50 respectively delay the signals from the adders A1, A3, A5 by prescribed delay time DLA, DLB, DLC. Multipliers M1, M3, M5, the delay circuits D13, D35, DF50 and the adders A1, A3, A5 form the musical tone signals for a left (L) channel. Multipliers M2, M4, M6, delay circuits D24, D60 and adders A2, A4, A6 form the musical tone signals for a right (R) channel. |
