Noise for high-hat sounds

The Liquid High Hat is a voltage controlled noise module designed by Ryk John Miller Thekreator. It is capable of producing high-hat sounds, but is also usable for other noise generation via control voltage. It is designed to run on 9/12/15V split supply, so should work with most any modular setup. It is comprised of very common parts, so there is no need for hunting down obscure/rare parts.

Hex Inverter Electronics has designed a circuit board for this cool project, to make it available for everyone. ?
