David,
OK...As I thought...on the Yamaha the registration changes must be able to be set/changed via the sequencer (midi type 0 file).
On the Korg we would have to change STS, but there is only 4 per song?? Maybe that's enough. It would also be nice to use song position pointer so we could go back to a certain section...will have to look into that...not sure it's suppoted on current instrument.

The Stagea Organ in my posts actually supports 16 registrations at any one time, quite nice.

What I would like is for someone here at SZ to do something like one of these songs (or similar). The brand of arranger doesn't matter. It's the technique we are after.
