Here’s a song I made with the Korg 707 from 1987. The Korg 707 is a digital FM synthesizer with 8 voices of polyphony.
”707” by The William Salmela Project
No other sound sources were used. The Korg 707 doesn’t have any built in effects, so the sound was further processed with the following equipment:
Boss CE-300 Super Chorus
EHX Small Stone phaser
Korg SDD-1200 (used this heavily for chorusing the sounds)
Roland SDE-2000 delay
TC-Electronic Powercore reverbs
