Korg PS-3100

The Korg PS-3100 is a polyphonic analog synthesizer released by Korg in 1978. It was the first polyphonic analog synthesizer to feature a built-in sequencer. It was used by many famous musicians, including Jean-Michel Jarre, Tangerine Dream, and Gary Numan.

The PS-3100 is a subtractive synthesizer, meaning it uses oscillators, filters, and envelopes to create sound. It has two oscillators, two filters, two envelopes, and a noise generator. It also has a built-in sequencer, which allows users to record and play back sequences of notes. The PS-3100 also features a built-in arpeggiator, which can be used to create complex patterns. Additionally, the PS-3100 has a built-in chorus effect, which can be used to add depth and texture to the sound.
