You can choose a characteristic of the channel fader curve on rekordbox.
Open Preferences; Controller>Mixer>Channel Fader Curve.

Hi!
DDJ-RR is a great controller, but mine have an issue.
Both chanel faders are glitchy. It is a new unit, not used. The midi data they send is slightly jumping up and down then faders are moved. Tested with different software, same problem.
Since I live in a remote part of the world, it is a problem to return it by warranty. So I need to solve the problem by myself.
Q: Is it ok to use Deoxit FaderLube or other lubricating liquid on these faders? Could it solve the problem?

Thanks, but it is not solving the problem. Then the fader is slightly moved up or down, the volume in the software is trembling like crazy. It looks that there is a mechanical defect.
Could you tell me if the faders are conductive plastic or carbon compound?
I am asking to know what lubricant to apply.
