" If I had had several generated MIDI tracks in there, would I have had to go through the same procedure four or five more times?"

No, just above the the 'specific DXi synth' option is one that will 'assign all midi tracks to Forte DXi' or whatever synth you have selected, so you would select the synth you want most of the midi tracks to play, then use the 'assign all midi to that synth' selection then go change the new track to whatever you want to hear.

Making adjustments in a DXi and not saving it as a preset will result in lost data sometimes.
There is likely a way to write that message (rotator on) with a control change, but if you haven't done it the 'send previous controllers' will not owrk. Somehow you have to save the rotator on message..

I do not work here, but the benefits are still awesome
