Dark Ambient Music created by a pair Yamaha TG-33’s. I got my pair of TG-33 sound modules in 1990, which makes them 30 years old this year, so it’s was good time to compose for them. The Tenebrous Geomancy of Diophantine uses only this 12-bit digital synthesizer as it’s sound source. Its 256 FM vector voices, along with its AWM, 32 note polyphony and joystick sound controller made this project a joy to create.
