Korg M1
The M1 was and still is a popular and widely used digital synthesizer and music workstation. The M1 features built-in AI Synthesis for full digital generation and processing using 4MB of PCM sampled and synthesized waveforms which can be shaped using analog-style editing. The M1 is capable of creating acoustic instruments with clarity, nice digital sounds and good buzzy techno sounds. The M1 is sort of like a workstation-version of the Roland D-50.
In addition to its acclaimed sound, it has a somewhat sophisticated 8-track sequencer. It holds 10 songs and 100 patterns and up to 7,700 notes, and offers full quantizing and editing. Full MIDI implementation suites the M1 ideally for studio production and MIDI system use. Up to 8 parts of multitimbrality with the 8 track sequencer makes for a powerful machine. Add to that a host of digital multi-effects and you've got one of the most widely and professionally used Korg synthesizers around.
UPGRADES: The EXK-M1 optional ROM expansion kit doubles the PCM waveform memory to 8MB (275 multisampled sounds) for even greater sonic possibilities. The EX-M1R is the same upgrade but designed for the M1R (rack version). That's right, there's a rack version of the M1 available as the M1R as well.
The M1 has been used by 808 State, Banco De Gaia, Ken Ishii, Depeche Mode, Fluke, The Cure, The Orb, The KLF, Plastikman, Bomb The Bass, Gary Numan, Robert Miles, Mike Oldfield, Kitaro, Rick Wakeman, Rod Argent, Joe Zawinul, Patrick Moraz, Pet Shop Boys, Vangelis, the Cranberries, Sin and Jellyfish.

The PCM samples have been used on countless hits. From the pan flute in incidental music to the piano and organ stabs within many house dance tracks. And so many many others.
The keyboard action was fabulaous too. light and playable.
Grab a M1LE and go down memory lane.
Still think it sounds good even today.
put this off!!! be patient with programming the 2 osc, try the cutoff at high rates. you'll hear much better sounds. the inner distortion fx is great when driving it to the open end, the m1 reaches its limit which sounds very interesting.
after having replaced the battery you have to initialize the factory presets again by midi dump.
don't forget to save all your prog, combi, seq, sysex midifiles before you do the battery change.
Does anyone know anything about where the internal battery is located on the Korg M1 Workstation? I opened it and looked but could not find the little 'coin shaped' battery.
Happiness to all of you helpers!!
