Audio Mixer within AB
So you have several different apps as inputs to AB.
And each has it's own nominal volume levels, and you could jump between apps and adjust each one in the app.
You could just set them all to max, and then click the "mixer" tab in AudioBus, and just level everything out right there.
And if those mixer faders were able to be controlled by midi CC, that would be even sweeter.
To me this would take this app to a whole new level of playability in live environments.
Right now I'm trying to find a workaround using the mixer in BS-16i, but that limits me to only using that one app.
I'd much rather have access to more apps on the fly.
