Here’s another classic video – this time of classic Korg synth action:
The theme music at the beginning was composed using the PS-3100 as the only sound source, without any effect or EQing.
The polyphonic PS-3100 Analogue Synthesiser had one dedicated VCO, VCF, VCA, and EG for each of the keys on the keyboard, for a total of 48 synthesizer circuits.
