Analog Hi-Hat / Noise-Generator

HH is an analog Hi-Hat and Noise generator with an internal VCA and decay envelope.

The Module can be triggered by a trigger signal at the TRIG Input. Using the DECAY potentiometer you can open and close the Hi-Hat. The ST Modular logo will flash according to the decay envelope.
This may also be voltage controlled with any CV signal at the CV input. The voltage changes the internal VCA offset, but does not affect the decay envelope. The incoming voltage can be attenuated using the dedicated attenuator potentiometer. An LED indicates the current state of the voltage.

Additionally you may also change the color of the noise being generated with the COLOR pot. Fully counter-clockwise the noise will equal Brown Noise with reduced high frequencies. At noon it will sound like Pink Noise, which is a bit louder at the low-frequency end of the spectrum, and softer at the high end. Almost fully clockwise it will be White Noise, broadly spread across the sound spectrum, sounding like a waterfall. Fully clockwise the noise will be boosted on all frequencies to have a more present noise spectrum.

HH is a very simple, but handy little module that completes any modular drum rack.
