Just got myself a Chocolate, too.
Nice little toy and quite nice for that ridicoulously low price.
I have an addition to the great instructions by @SrMouraSilva :
A little change in the section “Control an effect with the MIDI and the Mod Dwarf Footswitch” makes it possible to use both controls independently:
Set the CV logic Operator to “XOR” instead of “OR”.
(This means output is “on” only when exactly one of the two “Control to CV” is on and the other is off, and output is “off” when both Control to CV are “on” or both are “off”.)
Now any press of either the Dwarf footswitch or the Chocolate Switch will toggle the state of the controlled plugin.
Of course the problem of missing visual feedback remains, but we had that before anyway…
