Mystic Circuits 0hp And Gate / Vca

The 0HP VCA/ AND acts like a faucet: When a high control voltage is present, the input is allowed to flow to the output. When there is a low control voltage, the flow is restricted and nothing is present at the output. Using a high speed optocoupler, the module accepts audio at all inputs so audio-rate amplitude modulation is possible for pseudo-ring modulation effects. When used with gates at both the input and the CV input, the module acts as a logical AND gate (an AND gate outputs a high voltage when both of the inputs are high.) A built in trigger converter outputs spike whenever the main output transitions from low to high.

Whether you need some extra utilities for your studio behemoth or you need to save space on the road, 0HP gives you options.  Our modules come as a small circuit board mounted to a colorful piece of laser cut plexiglass, with a small chance to get one of our fabulous rare colors.  With a robust line of modules planned in the future, full DIY kits and an open hardware licence we aim to make modular synthesis accessible and fun for the veteran and new user alike.

This can be purchased as a kit which includes all needed parts and face plate.
