Well this is really puzzling. I've tried all of the keyboard shortcuts that relate to muting & selecting parts, and the shortcuts that relate to volume controls. They all work fine EXCEPT for CTRL+ALT+A and CTRL+ALT+S - increase/decrease master volume.
I've done a return to factory option (twice) and still these two options don't work.
Two further questions: is there (somewhere) an override box to check or uncheck to permit these settings?
When you use the two above shortcuts, should it show a change in the individual patch volume numbers? (0-127)

Barry, when I try the 2 culprit shortcuts, there is no change in volume at all, and I've tried both through the computer to an amp, and just through my keyboard.
