Uh oh, that ongoing oscillation even without sound sources sounds serious. While reseating boards was a good first step, the noise persisting even with them removed points to a deeper issue possibly in the power supply or mainboard. Suggesting specific fixes without further diagnosis is risky. I hig...

I haven't encountered that specific issue on the Matriarch myself, but don't worry, your service center approach is definitely wise. However, here are some additional things you could try in the meantime: Double-check cable connections: While you mentioned checking cables, ensure they're secure and ...

It's normal to hear more noise when hard syncing oscillator 2 or 3 with oscillator 1 on a Moog One, especially at higher notes. This is because hard sync involves forcing oscillator 2 or 3 to reset its waveform every time oscillator 1 completes a cycle. This can cause aliasing, which is a type of di...

I recently purchased a Little Phatty without USB and discovered that SW19 (OSC 2 LEVEL) is unresponsive. Despite attempting to clean the buttons, the issue persists. Even after removing the buttons from the PCB, the SW19 switch pad remains nonfunctional, although I can interact with other PCB switch...

Yes, it is possible to replace the cutoff potentiometer in the Matriarch. It is not a complicated process, but it does require some basic soldering skills. There are a few threads about it on the Moog forum. Here is a brief overview of the process: Remove the bottom panel of the Matriarch. Locate th...
