ADDAC System has announced an all-purpose VCA with an envelope section offering special versatility for percussion-based sounds.
ADDAC’s latest Eurorack module has been named Percussion VCA since most percussion instruments have sharp attacks with variable decays just as its AD Envelope. However, this can be used for any purpose where a VCA is needed including for CV signals due to its DC coupled signal path.
While deep in the Percussion VCA’s soul there exists 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 if driven to the extreme it will show its teeth and gnarly bite and chew on your cochleas with all its might.
On the Percussion VCA, 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. Meanwhile, the envelope decay can be controlled via its knob or voltage-controlled using the CV input and attenuverter, lending an enormous degree of sonic versatility.
Finally, the Percussion VCA can also be driven from a simple gate signal while controlling its decay, making it easy to plug a noise source, VCO, or any audio signal and turn that source into a percussive element.
The ADDAC816 Percussion VCA is priced €110 EUR. The module will also be available as a full DIY kit.
