Hi-Hat (Erica EDU Extended)

A DIY Eurorack hi-hat module, built based on the Erica Synths mki x es.edu series designs and thoughtfully expanded. The module is based on an analog noise source featuring bandpass filtering and VCA envelopes. Unlike the original, this version offers both Open Hi-Hat (OH) and Closed Hi-Hat (CH) modes, significantly increasing patching flexibility. There are two separate outputs, each with its own decay control, and the CH signal chokes the OH sound. The pots control the volume levels.
