Reply to can the modifier in Traktor pro make the controller back to default when switching?

The post about the modifier (midi mapping in Traktor pro) made my apc 40 a beast now that I can map twice as much buttons, however, I still have a question. Is it possible to make the functions reset to default when you press or release your 'shift' (modifier) button. I ask this because I want to map a knob to the EQ and to the dry/wet amount of an effect. It messes up your mix when you switch to the EQ and realize that the low frequencies are all blocked/boosted (because the knob was in that position when I used the effect).

As I fear, this might not be possible because a lot of controllers with knobs don't work with LED's and the knobs won't turn back to their default position on their own and the Traktor mapping is designed for all controllers. The Akai Apc40 can do this though..

Thanks,
