Thanks for coming back to this.
I use it a fair bit on CDJ’s during build-ups and breakdowns and other creative uses of white noise. I’ve tried it at various db’s and its pretty much unusable because of how it transitions way to sharply. You have to ride the upfader to get it anywhere near usable.
Ive even compared it side by side in my studio with my DJM900NXS2 and its pretty horrible to be fair. So smooth on the Pioneer mixers.
Setting it via channel trim knob rather than in the utility menu is pretty much common sense too imho. Really hope something can be done about it.
