I’m just curious how this is supposed to work. It looks like you can do it, but maybe it has to do with the way the MnM deals with CCs? Bank MSB sounds like it is simply just CC#0, so using CC#0 should work to change which Multi you’re using.

In any case, I emailed Waldorf, so hopefully they can point me in the right direction in how I can control which Multi is selected via MIDI. I’ll chime back in once I hear from them.
