Release notes:

Network MIDI 2.0 Spring 2026 Preview

No functional changes. This is a recompile to work with current shipping MIDI Service.

This preview does not have the entire Network MIDI 2.0 protocol implemented yet. It is of early preview / alpha quality, but may be used for testing and demonstration. Feel free to log/report bugs you run across. Please do so directly on GitHub.

Disclaimer

There is little/no customer support for this implementation of Network MIDI 2.0. Network MIDI 2.0 may impact the stability of MIDI on your PC. There may be breaking changes, including configuration file incompatibilities, introduced in future releases of Network MIDI 2.0 Only run if you are comfortable using early preview technology.

Required Service Permissions

To use Network MIDI 2.0, you must set the Windows MIDI Service to use "Local System" rather than "Local Service". This will be reset with each monthly MIDI update.

When we ship this in-box, we will have the minimum required permissions already set up.

Required Firewall Rules

Secondly, if you are running Network MIDI 2.0 for the first time, you will need to let the Windows MIDI Service through the firewall on your public and/or private network as appropriate. https://microsoft.github.io/MIDI/kb/network-midi-firewall/

Network MIDI 2.0 uses UDP ports on your PC.

MIDI Settings App

Please use the RC4 release of the MIDI Settings app. https://github.com/microsoft/MIDI/releases/tag/rc-4
