DIY 5th-order analog Leapfrog low-pass filter (based on MSK007)

DIY Eurorack Low Pass Filter module based on the unique core design of the North Coast Synthesis MSK007 Leapfrog VCF. This highly complex, all-analog filter features a 5th-order Leapfrog topology, delivering an incredibly sharp 30dB/octave slope. It offers manual and CV control over cutoff frequency and resonance, independent linear and exponential FM inputs with attenuators, and a built-in attenuverter for flexible modulation. It maintains low-frequency power even at high resonance and can track 1V/Oct for clean self-oscillation as a sine wave generator. This version is a custom build with a unique, clean front panel design.
