I want to map a knob on my control surface to control filter cutoff of a synth. I know I can right click and assign the function to the knob and everything works great. Problem is that when I change to another track with a different synth, that knob still stays assigned to the original synth on track 1. I have to undo the assignment from track/synth 1 and reapply it to track/synth 2. This is such a hassle. Is there an easier way? Do I need to make a combinator and assign my knob to that to get it to automatically switch very tracks without having to reassign it?
