Mixer Functions for composers
So working with pieces with many instruments the playback becomes a bit overwhelming. When you add an instrument to a large stack it would be very helpful to have streamlined mixer functions on the left side like a daw. I suggest three buttons: Mute, Solo, and Partial solo.
Mute: cuts that track from playback.
Solo: cuts all other tracks from playback.
Partial solo: plays all other tracks at 50% Volume.
Partial solo would be very helpful to allow the new lines being added to be inspected individually so any clashing sounds don't get buried in the big sound of the work.
