While deep in its soul there’s a standard VCA with exponential response that can be used as such, in its heart pulses an AD envelope with a sharp attack and a variable decay internally connected to the VCA control input. When it opens its mouth it can whisper in your ear but don’t let this soft demeanour fool you, if driven to the extreme it will show its teeth and gnarly bite and chew on your cochleas with all its might. The AD envelope has a fixed short Attack, just enough to avoid the typical “click” that happens when using a Gate signal to control a VCA, while the envelope Decay can be controlled via its knob or voltage controlled using the CV input and attenuverter. We named it Percussion VCA as most percussion instruments have sharp attacks with variable decays just as its AD Envelope however it can be used for any purpose where a VCA is needed including for CV signals due to it’s DC coupled signal path. Furthermore it also allows to be driven from a simple Gate signal while controlling its decay. This way it’s easy to plug a noise source, vco or any audio and turn that source into a percussive element. Width: 5HP Depth: 40mm Power: 80mA @ +12V / 80mA @ -12V
