Hexinverter Mutant Hi-Hats

A classic electro percussion synthesis design reborn as something completely different.

Hexinverter wanted to recreate a classic hihat synthesis design as something new and exciting, so they took the super electro 808 circuit and transformed it into a powerful creative tool for modular synthesis.

Features
Analogue hihat circuitry capable of synthesising vanilla TR-808 open and closed hihat sounds (simultaneously)
External audio input lets you synthesise hihats from virtually any sound source (Jupiter Storm, vcNOIZ, etc.)
Lo-fidelity original VCAs replaced by OTA-based modern VCAs
VCA DRIVE control for each hihat allows you to dial in anything from soft metallic hihats to extremely overdriven, crunchy hihats
Exclusive switch lets you select how the two hihats (open/closed) interact with eachother when triggered at the same time
Cutoff frequency control for internal resonant bandpass filter
Resonant filter can be switched on/off
Modular level mutual accent input (0-5V CV)
Trigger input accepts almost anything as a trigger signal
Non-invasive analogue optocouplers used for voltage control, thus, completely vintage sounds can still be had if that's what you're after!
Completely redesigned, hi-fi signal chain spares no expense by replacing cheap transistor amplifiers with low noise opamp and OTA equivalents

Redesigned by Erica Synths in close collaboration with Hexinverter.
