Tried searching but can’t find the same issue however there are similar drift issues seen with ohter controllers…
Windows 11 Laptop OS Version 24H2
13th Gen i7-13620H (2.4Ghz) 16GB RAM
NVIDIA GeForce RTX4060 GPU 8GB
DJPro 5.6
Rane Performer Controller V1.3.0.13 - display V1.3.0.1 - DSP V1.3.0.5 - Motor V5.1.0.0
The issue I’m having is when I have different sized loops running, say 4 beats and 8 beats, the speed of one of the loops will be about 0.4% off. The issue doesnt appear to happen when the loops are equal length. BPM will be the same but one drifts as soon as loop size is changed.
To reproduce it, set 2 loops of the same BPM with platters running. Sync them up with sync or by ear. Turn off sync if you used it. When they are the same length (8 beats) they stay synced once setup. If you change one to 4 beats, they will slowly drift apart. With sync on they stay synced but that doesn’t help as I play along side other DJs song for song and chasing drift constantly while looping gets tiring after a few hours of playing or when we are doing a longer mix together.
The same issue occurs if I stem split a track and have it playing without sync on as well.
Things I’ve tried…
- Different orientation of slip mats
- Changing “Tempo Change Detection” on or off
- Re-analyzing tracks
- Meticulously setting my own beat grids
Obviously I would expect tracks to stay relatively synced up once bpms are matched and matched by ear or at least after using sync then turning it off as that should sync the bpms exactly up.
I noticed the 0.4% difference mixing in with another DJ and I would consistently have to be -0.4% of his BPM with my shorter loops to keep synced up. When playing we are all on different controllers as well.
I have included a video for reference
Hope all that info helps and can get us to a resolution.
