Korg Forums

The software editor of the microkorg xl includes the converted patches of MS2000, MS2000B and the original microkorg. FYI

I usually use MIDI CC automation (not the parameter control), but same here. Looks like ableton can only show up to 128 parameters on the "parameter control" selection menu, and Mono/Poly seems to have more parameters than that. I think its an ableton matter.
Hope that helps.
