Syntakt Noise Issue via Overbridge in Ableton

Hello Elektronauts,

I have a Noise Issue with my Syntakt using it with Overbridge in Ableton.

Round about in the Frequency Section between 3k and 10k.

I want to record the analog Kick of the Syntakt via individual track (Track 9 - not the main out).
I set the gain in the mixer of the Syntakt down already. With that setting I do not hear any noise. But the gain is pretty low (peaks at round about -23 db in Ableton). So I insert a Utility in the channel increasing the gain so it peaks at around -6 db. But then I hear the Noise again pretty clearly.

Is this normal? Anybody with the same problem? How do you record the individual tracks of your Syntakt without Noise Issues?

Thanks in advance for your help!
Patrick
