Audible VCO signal Without Touching any Keys

Thank you JayBee808, The ribbon cable right under the envelope was the ticket, just pushed mine back a little, no more crosstalk, both line and hp jacks are clean now.  Took me awhile to find this thread, but the fix - 10 minutes.

Just wanted to say that I also had this problem.  Took it back to the place of purchase, and got a new one.  Tried it at the shop, and everything seemed fine.  Once I got home, I noticed that I still had the bleed, but only when I turned up the ultrasaw.  I can live with that.  Although it is a little annoying.

I'm a little paranoid about opening up the microbrute to fix the issue.

In my experience, analog synths will always require some maintenance.   I've owned many over the years and opened every one at some point.

That being said... I think this fix for the Micro is extremely easy. It is really a matter of removing a BUNCH of screws on the bottom panel, gently pulling it off and then pushing the ribbon cable.  Easy to reassemble. Honestly I trust this method of repair way more than shipping the board in for the same repair. You might even end up with a used replacement, who knows how Arturia is dealing with this.

I am guessing after time and movement (mine travels a lot) this ribbon will move and become a problem again. I'm just expecting to make this adjustment on occasion.

I am also trying to figure out if there might be a way to shield that ribbon so that there isn't the crosstalk problem. Any ideas would be great!

I realize this seems like a wrong but I truly believe part of owning any keyboard is the maintenance of it. The MicroBrute is no exception. It is a wicked synthesizer and I am not concerned in the slightest.

Let me know if you have questions, glad to help out!

I have the same problem but only from the main out any suggestions on how to fix it? I already used my warranty without asking them to fix that!

  I'm super happy that you guys figured out the ribbon cable was the problem. I opened up the back of mine last night and moved the ribbon cable that crosses over cirucuit board near the envelope section and the noise went away. I taped it with some electrical tape to the bundled cable right next to it so that it wouldn't fall close to the circuit board again. It's like brand new again.
I feel so relieved that this was an easy fix.

Thanks to JayBee808 for opening up his and letting us know!
