Korg M1 Digital synthesizer

The Korg M1 is a digital workstation keyboard that has featured on so many hit records, they were mass produced and are probably, the best-selling keyboard that Korg has produced to date. It has a 61-note keyboard with velocity and aftertouch plus multi-layer and split modes which is great.

It is capable of re-creating “real” instruments as well as synthesized sounds with good results, it has 4MB of sampled PCM’s and synthesized waveforms on board. It’s a unique sounding instrument that has been recreated quite well as a VST software plugin, also released by Korg initially as part of their legacy collection that also included: Korg Wavestation, MS-20, Polysix, Arp Odyssey and the Korg Monopoly!

The workstation like features include patterns up to 100, an eight-track sequencer, 10 full songs, and it has a load of onboard effects that sound good! It has been used by some top acts like 808 State, Pet Shop Boys, Gary Numan etc…

You can also get a rackmount version called the M1R by Korg if you are tight on space, and need the extra sounds that are doubled to 8 Megabytes worth, I know these days with things like the Komplete collection we are talking hundreds of gigabytes these days but hey, these were state of the art in the late 80’s and 90’s for music!

 

 

FINAL WORD:

If you can repair them they are super cheap and if not, no matter they are still cheap on the second hand market, but they are rather large and heavy, so expect to pay a lot in shipping costs if you can’t collect!
