USB Whining noise

Hi there,

my Polyend Synth produces constant usb whine after triggering any audio from synth - its always like it rings out after triggering audio from synth, so it is just audible while some other sound from Synth is audible - i tried to switch from Power Adaptor to Powerbank and also used different USB Cables -how can this be adressed?

I really cant stand it :frowning:
