Hello there!
I've had a Mopho x4 for 2 years now, and I have noticed that even with no LFO set to it, the LPF frequency is not always the same: when I set the resonance quite high, and for example a sequencer to repeat the same note, the frequency that is amplified changes slowly, back and forth. I have tried synchronizing the oscillators and setting slop value to 0, doesn't work. Actually even with both oscillators off (using only noise), the slow oscillation of the LPF freq is still there. It is not much, it would represent only a few steps on the 1-128 scale. When I visualize the LPF freq value, it stays the same over time, so it's not a pot thing.
Any help, any idea would be much appreciated.
A good day to you all!
