So I need 6 Knobs for Gain, can I use the Solo Buttons from EQ Mode? Are they different from Track Mode? Or can I use shift or Ctrl Button with them?
i was already thinking about how you would integrate this best (without cutting other functions).
Yes, Solo buttons in Channel-mode could be used. Although currently they still control Solo (also in Channel-mode) but this is not so important. I use it sometimes, if tweaking e.g. EQ or Comp in Soloed State, and want to quickly un-solo, to hear it together. But anyway, they could be used with Shift or Ctrl.
Disadvantage i see: you have to switch to Channel-mode, and there you are missing Scrubbbing/Shuttle-functions, which would surely be helpful while editing.
I would think/suggest it this way: why 6 buttons? if you have to switch modes, it´s more cumbersome to use, than to have it directly accessible.
What about just 2 Buttons, which do +/-1dB ? To do +3dB is just 3 presses of this button (but without additionally mode-switching). In current layout there is even a very nice free place for this: Ctrl+Bank <>
I think this could be a comfortable way - what do you think?
