Topic: Pitch drifting with DVS
Is this normal when using DVS? i need to constantly nudge the platters or hit sync to keep a mix in time.

Or is something else wrong, like my turntables not working properly?

i use 1200s and keep them on quartz lock, only adjusting the software with sync; but tracks do not stay synced for very long.

Are there settings to compensate for this?

i don't want to mess with the 1200s unnecessarily.

DVS implementation aside, pitch fluctuation are expected for motorized turntables because of their mechanics (wow and flutter), so having to make adjustments will always be a thing. Quality of the needles would also cause issues as well.

Once a mix is "locked" however from from a physical pitch adjustment and DVS processing + speed determination perspective (which could take longer due to settings), I've been able to leave a mix for about 40 seconds or a little more without having to intervene before.

What's the value of timecodePitchSliderIgnoreBend? That is a setting that that could delay speed processing, and I now normally leave that off, but unfortunately that does result in slightly more busy BPM readouts. Try on and off for the setting and see what works better for you.
If you are using Phase in DVS mode and its calibrated correctly/all goes well with phase behaving properly, it does perform pretty well as the needle + tonearm is out of the problem causing equation too.

Please note, other than that setting I mentioned before, there isn't the equivalent "antidrift" setting as people from Serato are accustomed to.

IMO it's not a major loss given DVS reaction time and processing quality is good enough to approach behaviour when playing a real record (which also doesn't have "antidrift"). However if you still have issues and can provide a video where you show the problem explaining where you think things could be better then the devs can look at it and see what can be done.
 

Appreciate that reply bro!

i understand the wow and flutter is unavoidable; 40 secs sounds good enough for me to keep it synced up.

i don't touch the pitch control on the turntables at all.

not using phase, i have ortofon Concorde MKII MIX they work for my scratching pretty well

timecodePitchSliderIgnoreBend is set to off, i will experiment with it.

Maybe we need anti drift in vdj lol


I accept dvs will not be rock solid, but i somehow think it could be a little better that what i currently experience in terms of the drifting .......everything else is great.
 

I'm with you on the potential for improvement here. Let us know if that setting helps though 🍺
