2hp VCO

Compact Eurorack oscillator module

The 2hp VCO is an analog voltage-controlled oscillator built around the reissued Curtis CEM3340 chip. It outputs triangle, sawtooth, and square waveforms simultaneously, with pulse-width modulation, linear FM, and hard sync. Accurate 1V/octave tracking across more than ten octaves suits both melodies and dramatic pitch sweeps.
