I recently bought a Denon DJ MC4000 controller and tried it with DJAY Pro for Windows.
Pre-cueing is not working (the button is not even lighting up).
You can see an image of the current settings:
Strange thing: if I change the action Note D#1 to “Cue Monitor” the CUE button is lighting up but no sound comes out from the pre-cue channel.
I’d love to buy a DJay Pro licence, but this issue is blocking me.
