Eurorack Zero Crossing VCA

'Persephone' is a VCA (Voltage Controlled Amplifier) using a discrete JFET as the gain element. The JFET can be tastefully (or violently) overdriven for saturation/distortion effects.

Persephone also includes a zero-crossing detector, which can be used to restrict gain changes to zeros in the audio waveform, preventing clicks and pops that can occur with very fast envelopes, especially on lower pitched sounds. In fact, with the zero-crossing circuit engaged, you can use a simple gate as the CV input without clicks.

Persephone draws up to 33mA on the +12V rail, and 26mA on the -12V rail. It does not use the 5V rail.
