If that’s the case with mix control, then maybe i’ll give it another go, thanks for the insight.
I’m trying to set things up so that I can process a vst with an external fx unit (eg KP3), and to process hardware instruments with vst effects, (which works fine now). I think I understand the theory of the mixer, but get lost in the practice.
Anyway, back to the manual…thanks again for the help.

One last thing , is it usual for the unit to get so hot?
I could probably cook on egg on it!!
