The huge success of the M1 lies primarily in the quality of its sounds.

The M1 was so popular that it was produced until the end of 1995, long after its successor T-series (the more advanced T1/T2/T3 workstations) was discontinued. The volume of M1's sales allowed Korg executives to buy back Yamaha's share of the company, a deal which had originated in the mid-1980s (though Yamaha kept making keyboard assemblies for Korg, the entire keybed is the same in M1, DX7 and several other Korg and Yamaha synths). In its six-year production period, an estimated 250,000 Korg M1 synthesizers were sold, making the M1 Korg's most successful synthesizer until the release of the Korg Triton. Outselling the Yamaha DX7 and Roland D-50, the M1 became the top-selling digital synthesizer of its time. The M1 featured a MIDI sequencer and a wide palette of available sounds, which allowed for the production of complete musical arrangements. The Korg M1 is a 16 voice, 8 part multitimbral, music workstation, manufactured by Korg, from 1988 to 1995.
