Can't get MG server to see windows native MIDI ports

MetaGrid Talk

I was able to install Windows loopback from the link provided (you need to enable developer mode in settings), but MG server does not see it. I disabled LoopMidi and rebooted and there was still no selection for Windows Midi. DO I need to configure something in MG server so that they use windows not loopmidi?

What Windows version do you have?

W11 home, 10.0.26200 Build 26200

I did install manually the new midi services from the link provided above from github.

For the new MIDI Services you need to have installed the KB5074105 (build 26200.7705) security update. Can you please check if you have got it on your computer?

I did a forced update, and this is now my version, which looks like a later build number, and it is not helping. No local windows selections only LoopMidi. which does work. but it would be nice to have it native.

As a note, I have both Loopmidi and MG Server launch on startup, however, MG server seems to start before Loopmidi and I need to stop MG Server and restart to see LoopMidi connections. I also get the Loopmidi error even if it is using Loopmidi! (error is in the first image above)

But no luck on Windows native midi. I did install Midi 2.0 also.

OKay, getting somewhere, I installed the packages that are linked from the MG server app, but that did not do it. I did a little digging on chatgpt and came up with this:

in a comman prompt window

winget install Microsoft.WindowsMIDIServicesSDK

I needed to make the midi remote surface again, but now it is working using native midi loop.

Hurray!

Brett - can you summarize your experience - that would be a great asset for the users.

OKay, so this is what I did to get native windows midi to work, you may not need all steps, but this is what i did and it worked:

  1. I switched windows to developer mode in ‘system advanced’ (you can do a search for developer mode to bring it up), there is a menu for developer mode, switch it on

  2. In windows update, if you don’t have ‘install all updates as they roll out’ checked, then do the optional install to get the latest build

  3. Then, as the MG server suggests, I went to Releases ¡ microsoft/MIDI ¡ GitHub and downloaded and installed Midi 1.0 Basic Loopback

  4. THen I went to Release Network MIDI 2.0 Spring 2026 · microsoft/MIDI · GitHub and installed windows.midi.services.midi2.0.preview…

  5. Then this is what brought me to the finish - I did this in a command prompt window ‘winget install Microsoft.WindowsMIDIServicesSDK’

  6. Then finally, run services.msc scroll down to windows midi services, and right click properties. Set it to ‘Local System Account’, this is important!

I would probably reboot each step, but it might not be necessary. Definitely at the end though!

Thank you so much for this - that will land in a dedicated post here and we will add it to the Help Guide.
