I have always wanted something -slightly- different. I would like to be able to hit a Ctrl-Shift-S or -whatever- and that the selected channels(s) instantly solo—regardless of whatever else is going on.
And by that I mean that I often am already soloing a bunch of channels and then decide I need to hear -just- one track. I want to be able to have a ‘temporary solo’… WITHOUT ‘forgetting’ the solo or mute states I had going.
