myMIDI Bridge

myMIDI Bridge turns your Mac into a MIDI-over-UDP gateway. It creates a pair of virtual CoreMIDI ports that any DAW, controller, or instrument can see, and forwards MIDI traffic to and from a UDP socket on your local network.

Use it to send MIDI between two Macs, between a Mac and an iPad, or between a Mac and any custom hardware or software that speaks plain MIDI over UDP — no extra drivers, no extra hardware, no RTP-MIDI session setup.

KEY FEATURES

• Two virtual CoreMIDI ports
  – “MIDI→UDP Bridge” — route MIDI from your DAW out to the network
  – “UDP→MIDI Bridge” — incoming UDP datagrams appear as MIDI in any app
• Bidirectional, low-latency UDP transport
  – Configurable send host and port
  – Configurable listen port
  – Raw MIDI 1.0 byte format — simple to interop with
• Built for macOS
  – Live packet counters and human-readable activity log (Note On/Off, CC, Pitch Bend, Clock, SysEx, etc.)
  – Local IPv4 address shown in Settings so remote peers know where to send
• Zero configuration to start
  – Defaults to your Mac’s primary IP on send port 51230 and listen port 51231
  – Settings persist between launches; changes apply on the fly

WHO IT’S FOR

Musicians, producers, lighting designers, MIDI hobbyists, and developers who want a no-fuss way to move MIDI between machines without RTP-MIDI sessions, network MIDI services, or extra cables.

HOW IT WORKS

The app exposes virtual CoreMIDI endpoints the moment it launches. Pick “MIDI→UDP Bridge” as a MIDI output in your DAW and every message you send is forwarded as a UDP datagram to the host you configure. Pick “UDP→MIDI Bridge” as a MIDI input and any datagrams arriving on the listen port are emitted as MIDI to your DAW or instrument.

This is plain MIDI over UDP — not RTP-MIDI. Pair it with another copy of myMIDI Bridge on the receiving Mac, or with any peer (custom script, microcontroller, OSC-to-MIDI tool, etc.) that speaks the same simple format.
