Maybe I’m missing something here, you know I’m a Roland man LOL, but can’t you just PLAY the chords into the chord sequencer on the newer Yamaha SX series, and save that as a file? That would give you the advantage of breaking it up into verse, chorus, solos etc., and allow you to restructure the whole thing at will….

The chord sequence still drives a style, so you can vary different styles when you feel like it, stick fills in where you feel like it, go to the ending when you feel like it etc. but it strikes me that this method you have doesn’t allow for restructuring the song unless I am missing some thing…

If you are one of the lucky Yamaha SX series owners or have a Genos, I have a feeling that using the chord sequencer may turn out to be a more flexible solution.
