I think I found a link to my personal tweaked out Fantom XR Cubase Profiles.
They’re pretty basic, but have been adapted to include bank changes. Some differentiation between GM and GM2 sounds. Clues as to how many tone generators a patch uses, etc.
While I install my XR as an external rack instrument in Cubase Pro, I do NOT designate the MIDI connection. This way I can easily swap between the multiple profiles for a given track.
I didn’t do anything too fancy with the sysex stuff. Merely an option to toggle between Solo, Multi, or General MIDI modes if one wants to do that.
