I would add a couple of things...
Option to have Bass Inversion ("on bass") via the footswitch as a MOMENTARY function. Press and hold the footswitch, bass line follows the lowest note played. Release the footswitch, now you can play chords any inversion and bass follows the root of the chord. If I choose to turn Bass Inversion on in the middle of a song, I don't want to press the pedal a 2nd time to turn it off. It should be momentary!
Chord Sequencer: YES!!
And finally... Roland's style control parameters are very sparse compared to the competition. Look at manuals for Yamaha and Korg. Search for terms like NTR, NTT, Close, Parallel, Retrigger, Repitch, Tension, etc. Nothing like this on a Roland! Some Roland styles sound very good. IF these parameters exist within the styles, they are hidden from the style creation workflow. Roland should make these details visible and give more control to the user!
