Hey guys,
I’ve been using my OP-1 as both a MIDI controller and as a sound generator, but when I plug both into my computer I get the high whining sound you hear at the beginning of this video: Ambient Video Entertainment Network - YouTube
Does anyone else have this? Have you fixed it?
ground loop isolator fixes this
its a common issue when plugging USB and AUDIO between two devices
turning off USB charging on OP1 is supposed to fix this
but it doesn’t always work…u could try that too
How do I turn off USB charging? Worth a try at least.
Didn’t work, but thanks for the tip!
I use a dongle on the audio cable to cut the whine. Even better is to use the USB cable for both audio and midi.
yea ground loop isolator will def cure what ails u
has worked for me for years
something like this

Ordered it! Will try.
Though, right now it seems a lot of the whine is coming from when I open up my streaming software too.
like my good man @mistercharlie suggests
if u update to the new firmware which opens up USB AUDIO streaming
by making the OP1 an audio interface
u can also get AUDIO and MIDI over the USB without any need to traditional audio cables and such
this would also prolly eliminate your ground loop
If the thing that @docshermsticks linked doesn’t work (it didn’t for me), try this:

It’s a miracle device!
The Design Isolator did work. The major whine came from the OBS software feeding back.
nice! glad u got it sorted.
fwiw the USB isolator linked above is the same thing as the AUDIO one i linked.
just isolates the USB instead of the AUDIO
the results would be the same.
i have both and have used both with much success
