Old Blood Noise Endeavors MTET MIDI To Expression Translator

Language is hard: let’s start at the start. Communication is complex, beautiful a real thorn in our sides. Many languages, dialects, standards. Some similar, some vastly different. A linear sweep, a barrage of Bits.

Music, of course, is meant to be the universal language, but our devices don’t see it that way. One could argue even we don’t see it that way – tonal and microtonal, EAST+WEST, free jazz and bubblegum pop. But we’re not here to argue. We’re here to blame the devices.

The MIDI To Expression Translator (MTET) does exactly what it says on the tin. It receives MIDI messages from external MIDI devices and uses those MIDI messages to create four separate Expression outputs for use with external expression enabled devices.

MTET uses a 50k digital pot, wired for TRS connection with the tip active (connected to the wiper). It is assumed the external expression-enabled unit will apply to the sleeve and reference voltage to the ring. It is configured to communicate with other devices using this standard. Its primary purpose is to interface with Old Blood Noise Endeavors pedals and serve as a communicator between them and a MIDI controller. However, it will work with many other units that use the same expression setup as OBNE.
