Changing Ensembles with CC or SysEx?

[m00dawg]

I've encountered a bit of a problem I haven't figured out how to solve when scouring the docs. Basically I have a song where I use a Multi patch and set things up so that MIDI channel 1 is the bass (left SID) and channel 2 is an arp (right SID).  Doing this requires I setup an Ensemble patch. No problem there. The problem comes when I need to switch the ensembles, say, during a live show.

 

I usually make patch changes in my DAW and want to eventually replace that with a MIDIO128. In either case, I can't find a CC or SysEx to actually change the ensemble. I seem to recall the SID panel for CTRLR can do it, so it seems like there is a SysEx solution, though it wasn't clear to me when reading the SysEx implementation.

 

Any ideas?
