Sometimes a MIDI OUT signal needs to be fed to a number of devices at the same time. This unit allows a MIDI signal to be fed to 4 devices. More devices can be used by combining distribution units.


The MIDI 4-way unit design utilizes:

  •  a MIDI 5-pin DIN input socket
  •  4 off MIDI 5-pin DIN output sockets
  •  Active electronic Schmitt trigger inverters, which clean-up the MIDI  signal
  • An opto-coupled MIDI input.
