The Mutant Brain is the central nervous system of a modern eurorack modular setup!

The Canadian company Hexinverter has today unveiled their first product for the Superbooth. Mutant Brain is a new straightforward MIDI to CV/Gate interface that features 16 Eurorack compatible outputs. An big advantage of this new module is the simple design of the module that doesn’t feature complicated menu diving. Also a good point is that you can all outputs can be configured with a wide range of different functions.


The Mutant Brain is the central nervous system connecting your modular analog eurorack system to MIDI gear, especially for percussion, polyphonic notes and sync duties! It packs 16 eurorack compatible outputs into a tiny, super affordable 8HP package. The 4 CV outputs and 12 Gate/Trig outputs are all universally reconfigurable. Triggers, gates, clock divisions and sync signals, polyphonic keyboard playing, velocity, sequencer transport, LFOs – you name it!

Configuring your patch is easy – just assign each output as you like in the Mutant Brain Surgery configuration utility, then send the MIDI SysEx file to the module and forget about it – the Mutant Brain remembers it all for you. We supply a convenient download pack of pre-configured, ready to use Mutant Brain patches for some select sequencing and drum machine devices on the market today, easily turning those sequencers and drum machines into a modular control powerhouse!

Designed with live and studio performance in mind, the Mutant Brain does away with wasted panel space and complex menu-diving interfaces, while freeing you from the limited “auto-learn” type MIDI interface. An auto-learn interface sometimes doesn’t play well with the limitless combinations of different gear setups which today’s modular performers play live with.


No menu diving, need to be tethered to a computer program, or accidental changes once the device is setup! Just turn on your Mutant Brain, play back your MIDI SysEx patch and the Mutant Brain remembers it for you until you want to change it. The 16 eurorack compatible outputs are all configurable as a plethora of different functions, with 4 CV outputs and 12 digital Gate/Trig outputs available to assign as you please.

  • All 16 outputs are capable of having different MIDI channels and/or note ranges assigned to them!
  • 4 CV Outputs (0V to 8V) can be
    • Notes (Mono or Polyphonic, V/Oct or V/Hz)
    • Pitch Bend, Velocity or Aftertouch
    • MIDI CC values (LFOs, modulation, etc.)
    • Fixed Voltage Values
  • 12 GATE Outputs (0 to 5V) can be
    • Note Gates and Triggers
    • Drum Triggers, Retriggers
    • MIDI Transport (Start, Stop, Run, Resets)
    • MIDI Clock Ticks (Divisions)
    • CC Value Above/Below Threshold
