Ableton microKORG editor w/ bidirectional editing.
On the microKORG, set the value of MIDI > LOCAL to EXTERNAL or AUTO. The default value (ON) may cause glitches in the SysEx communication.
Use a quality MIDI interface, not a 5$ no-name one. Cheap interfaces will scramble (if not filter entirely) SysEx and NRPN 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. Ableton is smart enough to override the channel value for standard midi messages (e.g. when using the Ext. Instrument device) but will have no clue on how to do so for the proprietary SysEx messages.
- Vocoder support
- allow editing RO parameters (by forcing a complete SysEx dump onto the microKORG)
SysEx parsing implemented using the official microKORG MIDI implementation specs.
Some additional information can be found in the Owner's Manual.
Based on Microkorg editor 1.0 by @dru93, itself a fork of Korg MS-2000 2.0 by @grymmjack (gh).
SysEx parsing code heavily inspired by @Jeremy's Building a Synthesizer Editor with JavaScript, Part 3 article.
