microKORG / MS2000 m4l device

microKORG / MS2000 m4l device

this is basically a device to control a microKORG / MS2000 from ableton.


nb: this device should theoretically work w/ a MS2000 though i don’t have one to try.

the microKORG is an often overlooked “beginner” synth but is in fact a MS2000 in disguise.

what it lack mainly is its bigger brother’s front panel controls, so programming it can be hassle (esp. due to lack of visual feedback). that’s the main reason why folks don’t go very far w/ it.

this device aims to solve this issue + allow params to be automated and controled w/ push.

what sets it appart from existing ones is:

  • automatic param value lookup on PGM change (via SysEx)
  • bidirectional editing: you can tweak params from ableton or the synth panel or both at a time
  • load / save program. supports both raw SySex (.syx) & KORG’s own format (.prg). saved files can also be dropped directly onto the device.


ableton w/ m4l, microKORG / MS2000, a decent midi interface


on the microKORG, set the value of MIDI > LOCAL to EXTERNAL or AUTO. the default value (ON ) may cause glitches in the SysEx communication.

if you use a MIDI channel other than 1, modify the value of the CHAN. control in the lower right corner of the device.

This rules, I haven’t powered up my microkorg in ages because I can’t stand programming it


for the few of you that might have downloaded the device, i’ve just released a new corrective version.

there was a bug when changing the selected timbre (for multitimbral patches).

I need to dig mine out again; there’s some patches on there that are particularly fun and I have no idea how I made them.

be sure to back them up (using the save button)!

new release, link updated in the first post.

new features:

  • can now edit program name, that gets stored when saving current program into a file. AFAIK this name doesn’t appear on the microKORG screen but may appear on the MS2000’s.


  • i had amp and filter envelopes mixed up
