Moduleur VCF

Diode ladder character with lowpass and highpass inputs, two CV inputs with logarithmic attenuverters and a fine adjustable maximum resonance. Optional EMC shielding is part of the design. Part of the Shmoergh Moduleur, a full DIY analog synth whose modules also work standalone in any Eurorack case. Split into a core PCB and a UI PCB; the core is mostly 0603 chip parts with JLCPCB gerbers and pick-and-place files, so the surface mount side can be fab assembled.
