Introduction
'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.
The module's signal and CV paths are 100% analogue (there is a little discrete logic involved in the zero-cross circuitry).

Without zero-cross detection, fast envelopes or gates cause clicks when the signal level suddenly jumps up or down.
With zero-cross detection, the clicks are removed.

The actual tone of the Persephone is glorious … Overall, and I do not say this lightly, the Persephone is probably the best small‑format VCA I have come across in Eurorack

Waveform magazine (issue 10) said
Persephone has some really excellent features and might just well set the standard for how a VCA sounds and acts
