Procedure to adjust digital gain needs to be added to the manual for firmware version 1.6. there seems to be no mention of it anywhere. Fortunately a good friend (Giancarlo Dellapina) pointed me in the right direction, otherwise i may have groped around... 


Also, it would be good to have the digital trim value show up when the Channel is selected, instead of the fader gain value... As it is now, unless you move the Select knob around, the Fader value does not change to show the trim value. Valuable info is hidden away until you actually CHANGE the trim level...

Jim, there's a short-cut for increasing the scene (by setting - either number or character) - push headphone+FF.

For editing the scene name more: push headphone+menu to get into the files/takes, and from there select "edit".


EDIT: I was writing from memory, but just checked and realized that there is one or two more step from there. I agree that it would be great to have a shortcut that takes you right to the edit scene name in one step.
