I want a method to adjust the base/treble balance on my Bose speaker amps for ALL songs both Midi and RT. I am using a Roland SD50 for Midi and a Focusrite for RTs feeding into a mixer. I have been playing around with the mixer tone control on the master slot but it doesn't seem to make any difference to the Bose sound.
What is the best way to do this so that I can adjust and save one overall master setting for each song.
