On at least a couple ‘real’ desks I’ve worked on there is a ‘solo memory’ kind of thing.
ie. you can hit the global ‘S’ button and cancel all solos but then, instantly get back to the solo selected tracks that you were just using.
One more time: you can toggle instantly between all solos off and a particular selection of soloed tracks.
And on one board (RAMSA?), it even had something like 3 or 4 ‘solo memories’ so you could instantly ‘channel surf’ between your last 3 or 4 soloed selections…
Kind of like the ‘Last’ button on a TV Remote.
I would find this -very- useful.
Maybe Cubase already can do something like this?
