Regarding your Qs regarding triggering and MIDI messaging, have you reached out to your local Support Team yet? It seems like they'd be the best to handle your predicament as they can walk through the DTXM12 in real-time and see if they can get the functionality you're trying to access to work. Their contact info is here

Thanks, and best of luck!
