I for one would like to see you offer TWO versions:
1) Basic Patch Selector for the SD2. No Auto-Accompaniment feature and offered at a lower pricepoint for the performing musician who just needs to access those patches in the fashion you have done.
2) Full Featured with AutoAccompaniment.
There is a need for both, I think. Guys like me don't typically want nor need autoaccompaniment but we do need access to the SD2 sounds in the organized fashion you are doing.
