Polyend Synth Ground Noise>\?

[lsober]

I opened a thread here regarding USB whining noise on polyend synth:

Electrical Noise / Possible USB Whine

Current Situation: Polyend Synth is off Connected via headphone out stereo split into two TRS into Digitakt II L and R Out from Digitakt II into Octatrack MK2 Result: there is an incredible amount of electrical noise from the Polyend Synth. I’ve tried many different combinations of cables and they all net the same result. Other machines don’t create the issue, even when using the same cables to connect. Not sure if anyone else has come across this issue?

Maybe you mean this?
