MIDItoOSC helps you monitor MIDI events and get OSC equivalent commands quickly for M32/X32 use cases.

What the app does

• Detects available MIDI inputs on your Mac
• Lets you select the MIDI source to monitor
• Shows incoming MIDI messages in real time
• Proposes equivalent OSC commands
• Lets you copy OSC lines directly from the app

Quick start

1. Open MIDItoOSC.
2. Select your MIDI input in the left panel.
3. Click Refresh devices if needed.
4. Move a fader or press a button on your mixer.
5. Copy the OSC command from the log.

Troubleshooting

No MIDI events appear

• Verify your mixer/interface is connected and sending MIDI.
• Check that the correct MIDI source is selected.
• Click Refresh devices after reconnecting hardware.

OSC line is not what you expect

• Confirm your mixer MIDI mode/channel configuration.
• Confirm expected X32/M32 mapping.

Copy works but target app rejects the command

• Confirm the destination app expects the same OSC format.
• Check value format (decimal separator, command style).
