MIDImult – Route a single MIDI source from the top input jacks to four separate MIDI devices. Includes MIDI 5pin DIN jacks and accompanying (polarity switchable for TypeA and TypeB) 3.5mm jacks on Input and Outputs 3/4, allowing connection to Eurorack and other modern MIDI gear. This is a simple implementation of a 74HC14 MIDI Thru 1 x 4 circuit in Eurorack format. This unit is available on my Store fully assembled or as a kit, note the SMD parts are small but doable for an experienced builder.
