Dual-Tone Generator A dual-tone melody generator is included to generate 2-channel music songs with a pleasant square-wave-like timbre. The pitch range of each tone generator is as wide as 4 octaves (48 different notes totally). The output of dual-tone generator can be mixed with the output of voice synthesizer to achieve voice playing with BGM (background music).
