The MX4 Buffered MIDI Multiple by 1010music serves a very simple but useful purpose: it takes in a single MIDI input and repeats it in real time to four MIDI outputs. The end result is you can now control four times as many devices from a single MIDI source.

The MX4 uses TRS minijacks for handy connection directly between the following devices:

- All 1010music modules, including MX4, bitbox, and fxbox
- The Arturia BeatStep Pro
- Novation products, including the Launch Pad Pro

The MX4 includes two MIDI adapters to connect with any equipment using the MIDI standard, 5-pin DIN connector, two TRS cables for MIDI patching and a standard power ribbon cable for connecting to your Eurorack.
