When using loop/slice A button, we have the following screen in help mode which is very helpful.
From my short experience the best chance to screw everything up is in envelope mode, especially when having samples on A7 and A8 and messing with A7, A8 knobs and faders. Knob 7 and 8 being vicious because they doesn t seem to be linked to values displayed on the screen.
So thinking about the following users waiting for the boat, I think it could be a lifesavior to have a “recommended fader and knob position” visual help in the envelope editor screen.
