Dont let the name fool you, this module is quite a bit more than just an envelope. ePatch in a gate and your output will behave as a normal sustain- release envelope, staying high while the gate is high and slowly decaying once it goes low. Patch in audio and you have an envelope follower, extracting amplitude data from whatever signal is coming in. Patch in any positive control voltage and you have a slew, adding glide whenever the incoming voltage falls. All three modes boast voltage control over the release / response time and can use the on board input mult to either daisy chain multiple envelopes or to extract amplitude data from an audio input and then send the audio somewhere else. Possibly Mystic Circuits' most useful 0HP module yet.

Whether you need some extra utilities for your studio behemoth or you need to save space on the road, 0HP gives you options. Mystic Circuits' modules come as a small circuit board mounted to a colorful piece of laser cut plexiglass, with a small chance to get one of Mystic Circuits' fabulous rare colours. 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.
