Hexinverter Électronique Mutant Brain

Easy to use web app for create your own mappings, I'm using with Bitwig, Octatrack and Pioneer Squid for sequence eurorack and works exactly as advertised. Powerful module for make Midi and eurorack talk.

I only returned this because I got into Expert Sleepers FH2, which allows to extend the CVs. But for basic use (pitch + pitchbend summed, sending 7bit CCs) - it is wonderful. Just decided on upgrade so preferred Fh2, but I just need more and higher bit outputs. Other than that - no glitches, and no settings load need when buffering eurorack - this is a pain with Fh2, for which I have to load configuration every start.

Very robust and straightforward design. Perfect to get the Eurorack to dialogue with other types of gear. A must-have!
Only tricky part is to configure it. You need a midi interface to communicate with your computer, so you can send the messages to program it. Tricky, but manageable, and absolutely worth the effort!
