I am trying to put 9 different synths on 9 tracks and assign their individual volumes to the 9 individual sliders on my m-audio axiom 49 controller. the idea is to use logic live and be able to slide the volumes up for the synths i want to use when i want to use them. This also would allow me to layer 2 or more synths at the same time. when I assign the volume of track-1 to slider-1, it works fine, but when i switch to track-2, slider-1 only changes the volume of track-2. If this isn't possible, I would settle for assigning buttons on my controller to toggle up and down tracks(button-1 toggles up a track and button-2 toggles down a track). I'm running logic 9 on my macbook pro 2011 if it matters. thanks for any help you might have.
