Hello Oziasjavier,
the Akai APC40 MK1works perfect with Watchout. You hav to keep in mind, that
all faders and encoders sends Midi-Control and the buttons sends Midi Note On/Off.
And the controller is working on several Midi-Channel, per default channel 1-9
For example: the first row on the left side is completely channel 1from top to bottom:
First 6 buttons, note 54,55,56,57,52
Switch , controller 23
3 toggle buttons, note 50,49,48
Fader, controller 7
Next column is channel 2, same notes and controllers.
And i think, the MK2 will work nearly the same way.
Have fun,
Heiko
