Monomachine SFX60 MKII: 2 Unresponsive Buttons

On my Monomachine the buttons Trig13 and Track4 are broken. Most of the time they don’t work at all and when they do, they both work and the respective LEDs light up as expected. That to me sounds like its not the buttons themselves but some chip along the signal path handling the input. I opened up the unit but didn’t find any obvious issues. I only have very basic knowledge of electronics and some soldering experience.
I’d appreciate any of the following help:

  • tips for narrowing down the problem,
  • chips or components that might be the problem, or
  • a recommendation for a repair service in Germany (preferably Berlin).

Here’s a video showing the problem on reddit.


I’d write to Elektron.

Good luck!

Also try the testmode at startup, which can give some clues into what is working and what is not.
