My ? is...is there a way to momentarily toggle mute, solo while in a live mixing process? In logic 9 i am in expert view in the control surface assignment window. I have assigned solo buttons on 8 tracks to my midi keyboards white keys starting at c1. The on/off toggle works fine. Press key down once to turn solo on, and then press again to toggle off. I would rather hold key down to toggle on, then release to toggle off. Does anyone know if this can be achieved in logic 9? Thanks!
