Available as an assembled Module and as a DIY project.

This Module is discontinued.

dual discrete core VCA

Features:
* dual VCA around discrete transistor OTA core
* switchable linear or exponential VCA response
* switchable between Audio (AC) and CV (DC) use
* starts to pleasantly saturate beyond levels of 10Vpp (clips at 20Vpp)
* envelope (unipolar) 0 to +5V CV input
* modulation (bipolar) -5V to +5V CV input
* smart normalization of unused envelope inputs to allow for full-range bipolar modulation

The VCAs in the Crux are built around newly designed operational transconductance amplifier (OTA) circuits, built from discrete transistors. If you need a super-accurate VCA, this is not for you. However, if you appreciate the warm and lively nature of discrete electronics, the Crux will serve you well.

A phrase often used among modular musicians is “you can never have enough VCAs”. Probably followed by “I need more rack space”. That’s why the Crux is a compact module, simple and straight, a short signal path, and no frills. As there are no frills, there’s little fancy text here. It can do what a VCA does. It can do it twice. It can do it linearly or exponentially, and does it on audio or CV. And that’s it!
