Loopmidi Windows 11: Patched

You will now see the familiar interface. Click the + icon at the bottom to create a virtual port (e.g., "loopMIDI Port 1").

You're looking for information on LoopBe1, a popular MIDI loopback device for Windows, and its compatibility with Windows 11.

LoopBe1 is a free, virtual MIDI cable that allows you to create a MIDI loopback connection between applications on your computer. It's a useful tool for musicians and producers who use software synthesizers, drum machines, and other MIDI-based instruments.

Regarding Windows 11 compatibility, there have been some issues reported with LoopBe1. The software was originally designed for earlier versions of Windows, and some users have experienced problems getting it to work on Windows 11.

However, there are a few possible solutions and workarounds:

To confirm, here are the system requirements for LoopBe1:

If you're still experiencing issues with LoopBe1 on Windows 11, you may want to consider alternative MIDI loopback software, such as:

Please be aware that you should only download software from trusted sources to ensure your system's security and stability.

Virtual MIDI Ports The primary feature of loopMIDI on Windows 11 is the ability to create an unlimited number of virtual MIDI ports. 💡 Key Feature: Port Persistence

Create Ports: Users can add and name custom MIDI ports instantly.

Seamless Routing: Allows internal MIDI data transfer between different applications. loopmidi windows 11 patched

Automatic Start: Ports are automatically recreated upon Windows startup.

Zero Latency: Provides high-speed, "patched" connections without physical cables.

Feedback Protection: Built-in detection to prevent MIDI data loops from crashing your system. 🛠️ Use Case Example DAW to DAW: Route MIDI from Ableton Live to FL Studio.

Controllers: Send MIDI from a software controller to a hardware synth emulator.

Legacy Support: Bridges older MIDI software with modern Windows 11 environments.

Troubleshooting loopMIDI on Windows 11: Fixes and the New MIDI 2.0 Patch

Recent Windows 11 updates, particularly the rollout of Windows MIDI Services (incorporating MIDI 2.0), have caused compatibility issues with third-party virtual drivers like loopMIDI. Users have reported that loopMIDI ports often become invisible or "grayed out" in DAWs like Ableton, Studio One, and Cubase. Why loopMIDI Broke in 2026

The primary cause is a conflict between the legacy loopMIDI driver and the new Windows MIDI Service introduced in preview updates such as KB5074105 and KB577181. This new stack introduces native multi-client support and loopback capabilities, which can supersede or block existing third-party virtual cables. Immediate Workarounds

If your loopMIDI ports have disappeared, you can often restore them without a patch by manually resetting the Windows MIDI service:

Stop and Start the Service: Open Windows Tools → Services, find Windows MIDI Service, click Stop, and then Start (avoid "Restart," as users report it is less effective). You will now see the familiar interface

Order of Operations: Start loopMIDI first to create the ports, then cycle the Windows MIDI Service, and finally open your music software.

Uninstall Preview Updates: If the issues persist, uninstalling preview update KB5074105 has been confirmed by users to restore legacy MIDI functionality. The Official "Patched" Solution

Microsoft has acknowledged these breakages and is rolling out permanent fixes.

Official Patch Rollout: A fix designed to ensure compatibility for loopMIDI and similar dynamic ports began rolling out on April 30, 2026 via the 30-day Controlled Feature Rollout (CFR) process.

Early Access Fix: For users who cannot wait, a "proper fix" for loopMIDI and rtpMIDI that removes startup order requirements is available on the Microsoft MIDI Discord in the #early-preview-releases channel.

Native Replacement: Windows 11 now includes Native MIDI 1.0 Loopback endpoints. You can manage these via the new MIDI Settings app (available in the SDK runtime), which performs the same function as loopMIDI but is built directly into the OS.

Microsoft has confirmed a official "piece" of software to fix this—a phased rollout starting the last week of April 2026—but until that is fully deployed, several community-verified patches and workarounds exist. Immediate Patches & Workarounds

If loopMIDI is currently broken for you, use these steps found in Steinberg and Microsoft Community discussions: Restart the MIDI Service (Most Effective "Quick Fix"): Open Command Prompt as Administrator. Type net stop midisrv and press Enter. Type net start midisrv and press Enter.

Note: Ensure loopMIDI is open before you restart the service for the ports to re-register correctly. Clean Hidden Devices:

Open Device Manager, go to View, and select Show hidden devices. To confirm, here are the system requirements for LoopBe1:

Uninstall any greyed-out MIDI devices and re-install loopMIDI as an Administrator. Disable the New MIDI Stack:

For some users, disabling the new Windows MIDI services in the registry or settings until the final patch arrives has restored loopMIDI functionality. The "New" Piece: Windows MIDI Services Loop Midi hidden in Windows 11 25H2 fix - Page 2 - Cubase

This report analyzes the current status of loopMIDI on Windows 11 as of April 2026, focusing on compatibility issues caused by the new Windows MIDI Services rollout and available "patches" or workarounds. 1. Executive Summary

LoopMIDI is currently facing significant operational issues on Windows 11 due to a major overhaul of the OS's MIDI stack (Windows MIDI Services). While loopMIDI itself has not received a formal "patch" to solve these architectural changes, Microsoft has acknowledged a bug where third-party dynamic ports (like those from loopMIDI) become invisible to applications. A formal system-level fix from Microsoft is expected in late April or May 2026. 2. Current Technical Status

Version Info: The current stable version of loopMIDI is v1.0.16.27 (released May 2024).

Core Conflict: Windows 11 update KB5074105 (and subsequent previews) introduced a new MIDI 2.0-ready service. This service often fails to recognize dynamic ports created by loopMIDI unless specific startup sequences are followed.

The "Invisible Port" Bug: Users report that loopMIDI appears to run correctly, but its virtual ports do not show up in DAWs or other MIDI software. 3. Known Issues & Official Acknowledgments

Microsoft developers have confirmed that dynamic ports (loopMIDI, loopBE, teVirtualMIDI) are not always visible in the new MIDI stack.

Good news: The developer hasn't abandoned us. Tobias released a patched version (often labeled v1.1.0 or higher, or specifically "loopMIDI v1.1.0 signed") that uses the new Microsoft signing process.

This patched version works seamlessly on Windows 11 without needing to disable Secure Boot or mess with bcdedit test mode.
