Bumping this up. Since this is a hidden gem for DJs!
Prime GO and GO+ users this feature is a great for layering loops (check the YT video in the thread), no other competitor has this type of feature. You can loop 2 tracks and play two other track on top making the Prime GO a pseudo 4 deck unit with automation!!
IMHO the Roll FX should be expanded from the current 2 beat to 16 beat or ideally back to the original 32 beat so it can be usable for DJs. 2 beat Roll isn’t usable for this feature.
You can vote here to get the Denon team to look at this feature again. Let’s get this going!
