Have you tried the controller with a different software? i.e. Virtual DJ?
In my case, I have the same problem as you, but strangely it only manifests in DJay Pro, not in Virtual DJ.
Moreover, there are also other users with the same problem with different controllers, i.e.:
https://community.algoriddim.com/t/play-pause-stops-working-and-sticky-scratch/26833?u=mrbig1964
I’m not here to defend or attack Algoriddim or Reloop.
I only want my problem solved.
But most of the evidences I collected until now points towards DJay having some kind of intermittent bug…
