The MIDI Bus is designed to add MIDI inputs and outputs for the Eurorack system, and more specifically for the TRAX sequencer.
It provides MIDI input/output/thru thanks to the three included 3.5mm to 5-pin DIN MIDI cables. These MIDI cables conform to the TRS MIDI B Spec Class, currently supported by Arturia, Novation, and 1010 Music devices. Beware, other companies such as Korg and Make Noise have products that use similar looking 3.5mm to 5-pin DIN MIDI cables, however their cables are wired in a way that is not compatible for use on the MIDI BUS.
It uses the power bus cable to receive and transmit MIDI-Data. In order to do this, the module repurposes what the eurorack standard defines as the INT GATE line of the power bus for MIDI IN signals, and the INT CV line of the power bus for MIDI OUT signals.
