AJ,
I'm talking "single push" increments. One digit at a time. In the main window .... select the button next to ... the bass part, for example. If you don't hold the button down, it won't change the value no matter how many times you tap it. I sometimes need very small volume changes, and I like to get to them fast. Are we saying the same thing? Is the track select, the buttons at the side of the window?
Anyway .... I support your decision to take a full refund, and start from scratch. The next wave of 2000's will hit soon, and you can try them out then. Until they arrive - start auditioning other possibilities ..... maybe a used X1? That'll give you a good harmonizer and a backup hard drive/arranger too.
