Hello there!
I have completed a build of Natural State. I am having a problem with channel 1. all the controls work perfectly including the cv ins, except the "open" fader. The cutoff frequency is always high (unless closed with negative cv voltage, or the internal LFO), and the open fader has no effect at all.
What does the "open" fader interact with in the circuit on Channel 1?
Many thanks. Channel 2 sounds great!

Stefan,
Thanks for your help. R41 was the issue. One side was not sufficiently soldered.
On to making music.
