Overview
Korg's M1, released in 1988, became the best-selling synthesizer of all time, with over 250,000 units sold. This AI (Advanced Integrated) synthesis workstation combined sampled waveforms with digital filters and effects, establishing the template for 1990s music production. The M1's factory presets defined the sound of late 1980s and early 1990s popular music.
The instrument featured 16-voice polyphony, a 16-track sequencer, and comprehensive effects processing. Famous sounds like "Universe," "Piano 16," and "Slap Bass" appeared on countless hit records. The M1 demonstrated that sample-based synthesis could achieve both authenticity and creativity.
Korg produced the M1 through 1995, with rackmount and expanded versions extending the product line. The M1's influence on music production cannot be overstated—it was the defining workstation of its era.
