I still think you're confused. This thing is a 16 part mutitimbral software module. It's just like any Roland HW module. It has a performance mode. Each part of this performance is assigned a MIDI Channel #. Within each channel you can choose different patches.
If channel #5 in the Edirol is trumpets you'd set RB MIDI Channel to Channel 5. If you want PATCH 6 within that Trumpets category you select PATCH 6 for that track.There is absolutly no way that the MIDI CHANNEL in RB can change. There is no MIDI parameter for that. The only thing that can change is the patch.
In summary the track you created should be CHANNEL#5 & PATCH # 6 (or whatever)
This thing is pretty much the same as the TTS-1 but geared toward orchestral sounds. Same layout & operation.
