PURPOSE:To generate a profound sound with a simple program by adjusting the entire amplitude level being the result of mixture of plural channel sounds. CONSTITUTION:Output sounds generated from waveform generators 61-66 of channels 1-6 are subjected to D/A-conversion by attenuators 71-76 and the sound volume is adjusted to a level depending on the channel ON/sound volume register of register array sections L1-L6 and the result is shared to right/left attenuators 10a1, 10b1, 10a2, and 10b2-10a6 and 10b6. The sound volume is adjusted to a level depending on the content of right/left sound volume registers and the result is mixed as the entire sound individually to the right/left. The sound volume of the left entire sound is adjusted by the left main attenuator 11a and the right entire sound is adjusted by the right main attenuator 11b based on the content of the main sound volume register 3. Thus, a profound sound is generated. |
