The Erica Black CV Expander is the satellite module to the HADSR envelope generator. It allows each envelope parameter to be controlled via external control voltage CV.
With this module you get unpredictable, complex envelopes that are ideal for random drones. It is internally patched to the Black Envelope generator via a ribbon cable, supplied with the module.
It can also be used with the Black Hole DSP (v1) in order to add attenuators to its CV inputs!
Power: 15mA @ +12V / 15mA @ -12V
