PURPOSE:To provide a mixer circuit for an electronic instrument capable of freely selecting and using an incorporated effect circuit even as a system effecter and even as an insert effecter. CONSTITUTION:After sound source signals supplied to input terminals IN1 to IN16 are level adjusted by various volumes, they are supplied to a transmission bus BS. The transmission bus BS synthesizes the level adjusted sound source signals with output signals of the effect circuits E1 to E4 connected by switches SB1-1 to SB4-4, and supplies the synthesis output to the inputs of the effect circuits E1 to E4. Further, the outputs of the effect circuits E1 to E4 are connected to an output bus BE by the switches SC1-1 to SC4-2, and after they are synthesized by the output bus BE to be outputted from output terminals OUT1, OUT2. |
