microKORG Patch Usage

Select any preset on the microKORG, then send the sysex data from the patches here using a MIDI system exclusive utility for your computer. The patch should load in “audition” mode on the microKORG. Play and tweak as needed, then save the new sound using the “Write” button.

If nothing happens when transmitting the sysex data, try setting the microKORG to receive on a different MIDI channel.

Thank you ! This is a really great sound. To turn it into something more “polyvalent” (a consistent bass with lighter keys in the middle-high), I’ve made it polyphonic and inverted the filter key track (-15). Sounds very good too I think.
