I would have thought this would be a pretty necessary function that merely requires an 'enable' button as well as a 'solo' button. I mean, sometimes I might have 11 tracks solo'd, but then want to quickly listen to just one. To keep muting the other tracks is just unnecessarily tedius.
Oh well, thanks. I'll try the workarounds in Nuendo.
P.S. If Steinberg are trying to avoid adding too many buttons, the simple solution would be to offer optional buttons, like in other programs. Is Reaper any better on this front? I'm becoming increasingly tempted to give it a go!
