Erica Synths Hexinverter Mutant Hihats

Hi-hats generator module - eurorack format

• Analog hi-hat circuit capable of open and closed TR-808 "vanilla" (also simultaneous)
• External audio input to synthesize hi-hats from almost any source
• Modern VCAs (OTAs) instead of the original lo-fi VCAs
• Dedicated VCA DRIVE for open and closed: from soft metallic to overdriven crunch
• Exclusive switch to define interaction between open/closed when triggered together
• Internal resonant bandpass filter with cutoff and on/off control
• Mutual accent input (0-5V CV) + very tolerant trigger input
• Reissue redesigned by Erica Synths in collaboration with Hexinverter

Erica Synths Hexinverter Mutant Hihats

A classic of electronic percussive synthesis, reborn as something completely different. Starting with the famous 808 "super electro" circuit, Hexinverter has transformed it into a creative tool for modular synthesis: an analog hi-hat generator capable of classic open and closed sounds, but with controls and flexibility designed for sound design.

TR-808, but with more control and range

The Mutant Hihats can simultaneously generate open and closed hi-hats in TR-808 style, but it goes far beyond "vintage cloned": the original low-fidelity VCAs have been replaced by modern OTA-based VCAs, while the audio chain has been redesigned in a hi-fi key with op-amps and low-noise OTAs. Voltage controls take advantage of non-invasive analog optocouplers, so you can also get fully vintage sounds when you want them.

Drive, resonant filter and open/closed interaction

Each hi-hat has a DRIVE control on the VCA: you can switch between soft metallic hi-hats and extremely saturated, "crunchy" timbres. The internal resonant bandpass filter (on/off) adds additional sculpting, with cutoff frequency control. A unique switch lets you choose how open and closed interact when triggered at the same time, expanding rhythmic and timbral possibilities.

External input and accent CV for ever-changing patches

The external audio input allows you to synthesize hi-hats from almost any source in your system (noise, oscillator, digital textures, etc.). In addition, the "mutual" accent (0-5V CV) allows dynamic variations at a modular level, while the trigger input accepts virtually any trigger signal, making the module easy to integrate into very different setups.

Reissue with Erica Synths Support.

After the closure of Hexinverter Électronique's operations (announced in September 2022), Erica Synths chose to continue production and support of some iconic modules. While maintaining functionality, the hardware has been redesigned in close collaboration with Hexinverter and support is guaranteed for reissue versions.
