Hi everyone,

I’m hoping someone here might have some advice! My Kontrol S4 Mk1 has developed a strange issue where the tempo fader just seems to have a mind of its own—it jumps around randomly, causing the BPM to fluctuate even when I’m not touching the controller. I’ve tried everything I can think of: recalibrating, double-checking all my software settings, and even giving it a good clean with a compressed air duster, but no luck so far.

It’s really frustrating since it’s messing up my mixes, and I’d love to get it back to normal. Has anyone else had this issue or found a fix? Any advice, tips, or things to try would be greatly appreciated!

Thanks so much!
