I know you are, my friend. I keep reminding myself that I am a WEIRD, unusual user with many specific needs, and not many manufacturers make what I want, right out of the box. The kb sounds are wonderful, but as a vocalist ...I need more control, or it's not going to replace my Korg.
I found that the only mode that works ok for me, is the "bassist" mode. That setting controls the harmonies best [RH], and gives me flexibility to play my own bass lines, which I love doing anyway. The transposer is bugging me a lot ... many bass samples disappear on the low C, if I go down more than 2 steps, and that's frustrating. I understand sound ranges, but no other kb seems to have that issue.

We'll talk after your break ... ALOT!
