Poly Cinematic Forum

Just got my Poly Cinematic and I love it. But it kind of 'crashed' really quickly. I fed it a sequence of notes via midi and a slow LFO into the Filter Freq CV from my Batumi module. When I switched to High filter on the toggle the noise became very bitcrushed, thin and squelchy. But when I switched back nothing changed and the knobs didn't seem to do anything. I unplugged the filter CV but I still couldn't get back my lower frequencies. I had to switch it off and on. Has anyone else experienced this?

What is the CV range for the Filt Freq input? And what about CV range of the other inputs?

Thanks
