Could really use the ability to control the level of each output through a software mixer, not just the cue mix. Or, if that's not possible for routing analog inputs to outputs, at least to control the internal level of each USB output (like you can in the cue mix).
Feeding most headphone amps with the analog outs results in distortion due to the very high output gain. I need to lower the output of the USB channels so the signal won't distort down the line.
