KORG M1 Workstation Synthesizer

The M1 features a 61-note velocity- and aftertouch-sensitive keyboard, 16-note polyphony, a joystick for pitch-bend and modulation control, an eight-track MIDI sequencer, separate LFOs for vibrato and filter modulation, and ADSR envelopes. Data can be stored on RAM and PCM cards.[6] The M1 has a ROM with four megabytes of 16-bit PCM tones — a large amount at the time — including instruments that had not been used extensively in mainstream music. The sounds include sampled attack transients, loops, sustained waveforms and percussive samples. The timbres include piano, strings, acoustic guitar, woodwinds, sitar, kalimba, wind chimes, and drums. Fact described the sounds as "wonderfully, endearingly wonky ... each one managed to sound simultaneously realistic and synthetic all at once".[6][4] The M1 also features effects, including reverb, delay, chorus, tremolo, EQ, distortion, and Leslie simulation, an innovative inclusion at the time. According to Sound on Sound, none of the M1's features was unique, but each was implemented and combined in a new way
