Issue 3: LoopMIDI disappears after reboot
| Tool | Pros | Cons | |------|------|------| | loopMIDI | Free, ultra-stable, low latency, unlimited ports | Basic interface, no built-in filtering | | MIDI-OX | Powerful filtering and mapping, great for debugging | Complex UI, not primarily a router | | CopperLAN | Network-ready, supports audio+MIDI | Not updated often, may cause crashes on Win11 | | Windows MIDI Services (Preview) | Native Microsoft solution, future-proof | Still in preview, limited app support |
For most Windows 11 users, loopMIDI remains the gold standard.
Absolutely. It’s a testament to good software design: simple, reliable, and universally compatible. Since upgrading to Windows 11, I have used loopMIDI daily for routing between Ableton Live, Reaper, MIDI‑OX, and various standalone instruments. Not a single crash or blue screen.
The only caveat is that it’s MIDI 1.0 only—but unless you own next‑gen MIDI 2.0 hardware (like a Roli Seaboard Rise 2 or a Korg Keystage), you won’t miss anything.
loopMIDI is a free, lightweight, open‑source tool that creates virtual MIDI cables inside your computer. Think of it as a patchbay: you create one or more “ports.” Any MIDI data sent to an output port is immediately available as an input port in another application.
For example:
On Windows 11, loopMIDI works exactly as intended because Microsoft preserved the underlying MIDI APIs (WinMM and MIDI Services). The tool hasn’t needed a major rewrite—it just works. loopmidi windows 11
A pop‑up will ask: “Do you want to install this device software?” Click Install. This creates the virtual MIDI driver.
The main window is minimalist but powerful:
Important: Ports are not persistent by default. If you close loopMIDI, the ports disappear. To keep them: check “Enable port creation at startup” in settings, or create a Windows Task Scheduler rule to launch loopMIDI minimized on boot.
If you are a music producer, streamer, or hobbyist running Windows 11, loopMIDI is not optional—it is required software.
Don't let the retro interface fool you; under the hood, it is a precision tool that solves a complex problem with elegant simplicity. It runs perfectly on Microsoft's latest OS and remains the gold standard for virtual MIDI routing.
Recommendation: Download it immediately and put a shortcut in your Startup folder so it's always ready when you open your DAW.
For years, loopMIDI by Tobias Erichsen has been the gold standard for creating virtual MIDI ports on Windows. However, the landscape for loopMIDI on Windows 11 is shifting due to major operating system updates. While loopMIDI remains a critical tool for many, Microsoft is now integrating native "loopback" capabilities directly into Windows 11 through its new Windows MIDI Services. What is loopMIDI?
loopMIDI is a lightweight utility that creates virtual MIDI-ports to route data between different software applications.
Primary Use Case: Interconnecting applications that require hardware-style MIDI ports (e.g., routing a software sequencer to a standalone synth or DAW). Issue 1: “The device does not exist” error
Key Advantage: It is simple to configure, allows up to 16 virtual ports, and is completely free for non-commercial use. Using loopMIDI on Windows 11: Challenges & Fixes
Recent Windows 11 updates (specifically version 25H2 and later) have introduced a new MIDI 2.0 stack that can sometimes cause loopMIDI ports to become "invisible" or stop working in certain DAWs like Cubase or VST Live. Common Troubleshooting Steps
If your loopMIDI ports are not appearing in your music software, try these community-vetted solutions:
Correct Startup Order: Always start loopMIDI before opening any other music applications.
Restart the Windows MIDI Service: If ports are hidden, go to Services.msc, find the Windows MIDI Service, stop it, and then start it again (avoid using "Restart").
Check for Windows Updates: Ensure you have the latest cumulative updates, as Microsoft is actively releasing fixes for the new MIDI infrastructure. The Future: Native MIDI Loopback in Windows 11
Microsoft is gradually rolling out Windows MIDI Services, a complete rewrite of the Windows MIDI system. This new service includes built-in loopback endpoints that function similarly to loopMIDI but are integrated directly into the OS. Loop Midi hidden in Windows 11 25H2 fix - Steinberg Forums
