Extreme noise on new Korg Minilogue

Hi all

I'm running in a problem with my new Korg minilogue. As soon as the synth is connected via USB there is unwanted background noise (like ground loop noise).

My setup:
- Lenovo T460s
- Focusrite Scarlett 2i4 2nd Gen
- Korg Minilogue

The same problem exists with the Moog Minitaur. Is there any solution?

Thank you guys!

Try different cable.
Try different USB port.
Try using a USB hub, preferably a powered one.

This seems to happen sometimes with USB.

Thank you guys. I guess it is my usb hub. Sometimes it works, sometimes not. I will get a new one and if i still get a noisey sounds out of the korg, i'll buy an usb isolator.

Hey Memfixx,

Did you end up fixing this? I've tried loads - new USB cables, no hubs, direct into mac and I'm still getting a humming noise. I also purchased the Behringer Hum Destroyer (HD400), but this didn't fix.

What I've noticed is it only happens when the USB cable is plugged in, even if the Minilogue is OFF - there's still a hum!

I called Korg but they couldn't help me :( has anyone experienced this and solved the problem?

Thanks in advance

GuitarHero, and anyone else reading this thread... I too had horrible, horrible grounding feedback when connecting my Minilogue via USB. Here is the product I used which eliminated it: HiFimeDIY USB Isolator Only £23, absolutely did the trick. I still have some grounding noise but that's coming from the audio interface / is present with or without the Minilogue. Need to stump up for a high-end isolator that can handle 192khz bandwidth then it'll be plain sailing!

For anyone with this issue still, I noticed it goes when I unplug the laptop power supply. Not really a solution but could be useful.
