Abstrkt, I don’t work for Soundmachines either. I was able to do the patches in the manual with no problem. I assume you have played with all the knobs, turning the VOLUME OUT and INITIAL up, turning the filter FREQ up, and so on. You are able to hear the filter self oscillate, so the sound output is getting out okay.
My one thought is that sometimes it’s hard to tell which pin is which. Maybe you connected the oscillator to the CV of the filter? That’s something I could imagine myself doing. See my post “Make your nanosynth easier to patch” for how I marked the pins to make it easier to see what’s what – for me, anyway. Or look at my avatar.
Good luck. Maybe it is a hardware problem. I hope you get yours working, or get one that works.
