【Arturia Keylab MKII】knob's CC is not smooth

[soundest]

When I turn the knob slowly, the CC information I write is not smooth, and sometimes it jumps back a little bit on Analog Lab 4.

Thanks

Hi and welcome to Arturia forums.

Do you have the same behavior with other software than Analog Lab?

Do you have this issue with all the encoders?
It's a behavior a malfunctioning encoder can have. I would test the midi output to see if the encoder send out jumpy values like this.
