I just installed VSL Bosendorfer, on my brand new Mac powerbook with 10.7.4, and when I play certain notes, the notes come out wrong, and when I depress the sustain pedal, the entire tuning of the keyboard changes. This happens whether I use either of my midi keyboards, or if I use my mouse on the on-screen keyboard. Does anyone have any idea how I can fix this? I can't find anything about it on this site or in the manual. Help, anyone?
