Please help me with my LoopMidi issue, i'm desperate

Good afternoon everyone,

If you search on Google for Windows 11 25H2 and LoopMIDI, you will find at least four posts from me. Unfortunately, I still haven’t found any answers or any solution.

Here is a brief summary: I am running the latest official version of Windows 11 25H2 and I use LoopMIDI with a Stream Deck. Without making any system changes, yesterday morning the LoopMIDI virtual driver disappeared again from Device Manager. It is as if LoopMIDI was never installed.

This has been happening for months now and the situation is becoming unmanageable, because I have no idea what is causing the problem. The last time it happened, I rolled back to the official Windows version and removed all updates. Everything worked correctly until yesterday morning: I turned on the PC and LoopMIDI was gone.

I have the new Windows loopback ports enabled, but they do not work with the Stream Deck to operate as Mackie Control.

What I have done:

Reinstalled the official version of Windows

Completely removed everything from the PC and cleaned the registry from any trace of previous drivers

Installed MIDI Settings, but LoopMIDI is not recognized, so stopping and restarting the MIDI service has no effect. The device is simply not detected by the system

Installed SBVMidi, which only caused crashes and system reboots

Deleted MIDI entries from the registry using the dedicated tool, but with no success

The only thing that changed was an NVIDIA update. I reinstalled the Studio drivers, set power management to maximum performance, disabled overlays, never install the audio drivers, and performed a clean installation — still no success

I am desperate. I don’t know where else to look, and the most frightening part is that this happens suddenly from one day to the next.

Is there anyone who can help me?

Thank you very much.Screenshot 2026-02-19 172932

Yes! God bless you for the YT video, Xavier. It solved my problem immediately. For anyone looking for the quick fix for loopMIDI stop working in March 2026: Win+R -> services.msc -> Windows MIDI Service -> Restart. Working again. Repeat as many times as needed, since it's a current Windows issue.

    Hello Roberto Tafuro, welcome to Microsoft Q&A forum.

    I understand your frustration—months of this happening with no clear cause is incredibly stressful.

    Have you seen this article from the Windows MIDI dev team? https://devblogs.microsoft.com/windows-music-dev/windows-midi-services-rollout-known-issues-and-workarounds/

    The Windows dev team is currently making significant changes to the MIDI stack. Because of this rollout, issues with virtual MIDI drivers like loopMIDI are expected, and they're actively monitoring and communicating about them.

    The article covers several known bugs and workarounds. I've looked through it, and unfortunately your specific symptom—the driver completely vanishing from Device Manager—doesn't appear to be directly addressed. That said, you might still find one of the workarounds helpful.

    Note that the Q&A forum is mostly peer-to-peer support from normal users like yourself. Since the issue involving the new MIDI architecture and is quite technical, I'd recommend raising it on Microsoft's MIDI GitHub: https://github.com/microsoft/MIDI/issues

    The GitHub repo is where Microsoft developers and technical contributors are actively working on these exact issues. They'll be better equipped to investigate your case in depth.

    I hope this points you in the right direction.
