high pitched whine with USB connection.

Recommended Posts

Hi all, I've recorded a video showcasing a really high pitched whine I can't get rid of whenever I hook up the XW-PD1 to my computer with the USB cable.  The whine is present even when monitoring the XW-PD1 directly with headphones.  I've tried nearly everything: different computers, different audio interfaces/mixers, different outputs from the XW-PD1, the whine occurs even when the XW-PD1 is powered off.  Watch the vid please and you'll hear what I mean.  In my opinion, it renders the unit useless for DAW control.  Is there any way to overcome this?

Hi.  It's a USB ground loop. Normally I recommend simply swapping over to standard MIDI connectors, but of course the Trackformer has none. So....  Do an online search for "usb ground loop" and you"ll see solutions like USB ground isolators.

Hey Brad, you're right on the money.  Thanks for pointing me in the right direction.  I didn't know what I should be searching for, but now I do.  I found several USB ground loop isolators on Amazon.  I saw that you had posted something else earlier and deleted it perhaps.  I was wondering if something like a Kenton USB Midi to DIN Midi might isolate the noise as well, but that might be less guaranteed.  In any case, I appreciate the response.  I'll probably update the thread once I confirm the issue has been resolved.

Yeah, I deleted a reply I typed up when I looked at the video and realized you were talking about the XW-PD1, not the XW-P1.  I read it wrong.  :facepalm:
