I've noticed that the volume goes down slightly when activating Pitch.
The Roll effect is still not right either.
When activated it sort of stutters before rolling as it should -as if it skips a beat.
It prevents me from using that effect because it sounds crap when activated.
Happens every time and on every track.
I think it's a rekordbox software bug in Performance mode as The DJM mixers I've had (in Export mode) never had this issue.
