Korg M1
The Korg M1 is a 1988 sampling-based music workstation with 16-note polyphony, 16-bit PCM sample playback, built-in effects including reverb, delay, chorus, tremolo, EQ, distortion and Leslie simulation, and an eight-track MIDI sequencer. It uses sampled attack transients, loops, sustained waveforms and percussive samples. It was the bestselling synthesizer ever at that time, selling over 250,000 units. None of its features was unique, but their integration was unprecedented.
