River Creative Technology Crux VCA

 

river creative technology crux vca

documentation and demos here: crux

the kit comes with SMT parts pre-assembled on the PCB

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) and modulation (bipolar) CV inputs
smart normalization of unused envelope inputs to allow for full-range bipolar modulation
 

"After overlooking VCAs for many years, I began to appreciate the huge range of functions they can serve up. They’re really everywhere, in simple loudness contouring circuits, tremolo effects, tone controls, filters, overdrives, mixers, amplitude modulators, panners, cross-faders, and CV performance controllers. I also learned that VCAs put their subtle signature on the overall sound of an instrument. 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!"
