I can't even think straight right now. For days I've been trying to send midi out to an external midi plugin (Scaler, Cthulhu, etc...) and have it come back into maschine MK3 so I can record the MIDI. I found nothing on the internet, or in the manuals. The onboard Maschine arpeggiator is useless because it has no trigger settings, and the harmony feature doesn't allow inversions, or any type of chord manipulation features whatsoever. I'm at the point where I just want to return this thing and be done with it. Sorry if I sound upset but I just can't imagine why this is so difficult or impossible to do this.
