Thanks RKL!

You've given me the way forward.

I expect I could either freeze the non-melody/ solo tracks once I put in the bank/ program select ... or simply save the song. Saved songs don't 'regenerate,' do they?

I've also noticed that you can click on the patch names in the drop down list in the '+' window. Pretty cool for 'call and response' to a melody line. I'm hoping that those 'changes' could also be written or midi recorded.

I'd already checked out putting in the bank/program change in a song, exporting it as midi and then dragging it into my sequence, Cubase, hooked up to the same synth. The changes were written to the midi file.

I'm seeing some great 'eazy arrangement' possibilities.
