Hi Tom,

It does start to look as if there's some conflict between PT and the A-33. Certainly, if PT enters notes ok using the mouse and a re-set on the A-33 cures things for a while, that's what I'd guess. Have you got access to any other keyboard just to try it? If it works ok, then we start to look at what problems the A-33 might have.

I'm not a Band In A Box user, so maybe someone else can pick this up?

ROG.
