I think this would be quite a useful feature. It could be done in the same way that you increase/decrease the octave or key of a highlighted pattern through the menu that pops up when you right click. It would probably be quite useful if you have various different volumes in the volume column and want to increase/decrease the overall volume of the pattern. (for easier channel/volume mixing)
Example:
C-4 01 6
C-4 01 8
D-4 01 4
E-4 01 7
F-4 01 A
G-4 01 B
would change to:
C-4 01 7
C-4 01 9
D-4 01 5
E-4 01 8
F-4 01 B
G-4 01 C
When highlighted and "increase volume" is selected on the right-click menu, or
You can do it now, kinda. You have to select the volume column (easiest by going with the keyboard to the top of the column and pressing Shift+End) then Shift+Scroll Up or Down depending on the direction you want to go. It's a bit roundabout, so having a dedicated option for it would be easier, but it would still be slightly unwieldy if you want to go more than one step.
EDIT: Also, this belongs in the "Bug Reports & Requests" forum. This forum is more for talking about the development of the program itself, less about feature requests.
Sorry about posting this in the wrong subforum, I guess I wasn't thinking straight :P
I can't seem to get it to work by doing it the way you suggested, not sure what the problem is.
I still think it would be a nice option, though. For instance, say you wanted to increase the volume of two channels up to even a whole frame, having an option in the right-click menu would make things easier. Also, it would just fit up in there nicely with octave changing and key changing. (that's probably more just my subjective opinion talking, though.)
