I haven't fully tested my assumptions yet. But it appears from reading the manual *and the addenda* that both Peformances and OTS have "holds." There's a lot of overlap among parameters between the two sets of holds. This could be why some people swear there are bugs in the performance workflow.

My plan is to have the Performances hold everything EXCEPT the Arranger Type (e.g. chord recognition mode.) So using the pedal to momentarily select an alternate performance will only change the chord fingering. It will work like the Shift key on a typewriter or computer keyboard. Releasing the pedal will restore the default Intelligent mode chord recognition.

I'm hoping to use OTS to change everything EXCEPT the chord recognition. Essentially this is the inverse of what I'm doing with performances. So selecting a different OTS will change the part voicing, Melody Intelligence, etc. In some cases also the selected style variation, triggering a fill-in, etc. The only thing this OTS-based approach WON'T allow me to do, is to easily use two different styles for the same song (because the OTS is contained WITHIN its parent Style.)

My intention is to choose the most appropriate ROM style for a song in my playlist. Save a copy of that style to the USB stick, named for the song. Customize the tempo, OTS, and rhythm part voicing appropriately. Save the edited OTS, and then save the whole style again to the same location (overwrite.) In some cases multiple songs might be based on the same ROM style. Hopefully I'll be able to customize the styles enough to prevent obvious repetition.

Regarding ease of access, I guess my thought was to save the custom styles in sub-folders on the USB stick. Right now I don't play that many different songs. Perhaps eventually I'll have to organize them by genre, or alphabetically.

With over 1500 ROM tones to choose from, I think I can find some that are suitable. Most of the time my part voicing will be selected by the OTS (which hopefully also save the FX.) But when I'm practicing, experimenting, etc., having some Favorite ROM tones handy will make things fast and fun.

I suppose my approach is different from most people's, and not strictly what the programmers intended. But the beauty of these instruments is that they are customizable, which allows them to acommodate a variety of work-flows and levels of playing skill.
