I’m not sure how relevant this is to people, but it occurs to me that having a second mute and a second volume both of which would not be automatable but still visible on the mixer would be very useful.
I find myself using Free-G a lot because it’s a simple and quick way of scaling the volume of track that already has volume automation on it; the trimmer could be used, but sometimes you don’t want to play with the gain there. I could also in principle use the mute on it to create an absolute mute that isn’t subject to Nuendo’s automation. But it would make so much more sense to have both of these on the mixer where they can be enabled disabled and visible at all times.
The volume is a more complex proposition, but the mute could simply be a click + modifier key that enables a global mute that nothing can alter but the same (it could even use the same button but turn it a different color).
