Expert Sleepers Persephone, a new JFET based VCA module for Eurorack that brings clean and musical overdriven tones to your system.
Most people know Expert Sleepers for their super flexible audio/MIDI/CV interface modules but also for the deep Disting multi-function series. For some time now, Andrew Os from ES has also been making very clever analog modules. Much simpler than his previous works, but all with unique twists.
Shortly before the end of the year, ES has another newcomer with the Persephone, a unique VCA module with an overdriven characteristic.
Expert Sleepers Persephone
Persephone is a new 8HP all-analog VCA (voltage-controlled amplifier) that uses a discrete JFET as the gain element. These are very suitable for musical saturation and distortion effects thanks to the ability to overdrive them.
The module also includes a zero-crossing detector. This 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. A very handy functionality. If this circuit functionality is on, you can use a simple gate as the CV input without a click.
On the connection side, Persephone has two audio inputs (2 to 1 sum) and two CV inputs where the first has a dedicated attenuator. Then, it has a mono audio output and a CV output. Clever, you can work with the pre and post knobs to bring in the overdrive timbre while controlling the output level. With the asymmetry switch, you can add another character to the saturation.
At first glance, a very tempting module. I like it a lot that it’s not just another VCA again but one with a special character and design.
Expert Sleepers Persephone is available soon for $185 USD
