Overdrive, Filter, Bit-Crusher/Sample & Hold Module

OVERDRIVE:
Discrete analog overdrive circuit inspired by the mini Moog mixer section. Tonal characteristics vary depending on the amplitude of your source signal. Ranging from soft-saturation to full-blown transistor overdrive and distortion. Use the second pair of in/out to feed the signal back into itself for a wild “sub-octave” effect . Or, send your overdriven signal into the neighboring filter and then back into the overdrive for untamed feedback effects. This circuit is designed to be pushed to the max! For line-level signals, it's recommended to scale up to Eurorack levels for best results.

FILTER:
Classic OTA-style analog high-pass/lowpass resonant filter. The filter can be soft and sweet, or, add a little resonance and prepare for some angry screams. For both lo & hi pass configurations, the filter is capable of self-oscillation that can be used as a dirty sine wave oscillator. Volt per octave pitch tracking, and CV modulation with attenuator included for full control over the shape of your sound.

SAMPLE & HOLD:
A precision sample & hold circuit with a low droop rate. Fully analog. Normalled internal clock is configured for audio rate decimation effects to mid-speed sample & hold. However, the external clock input allows you to use this S&H section as a traditional sample and hold (semi-random/stepped voltage source, sample rate reduction)
