This is precisely the problem that by Tobias Erichsen was designed to solve. loopMIDI is a lightweight, free, and incredibly popular tool that creates virtual "loopback" MIDI cables on your system, allowing you to route MIDI data between different applications as if they were connected by a physical cable.
Imagine you have a MIDI controller—like a keyboard, a pad controller, or even a smartphone app. You want to use it with . Maybe you want to control a synthesizer in your DAW (Digital Audio Workstation) while also sending the same data to a notation program or a visualizer. On Windows, that's not how MIDI normally works. By default, a physical MIDI port can only be used by one piece of software at a time.
He downloaded the tool, and within seconds, a small, unassuming window appeared on his taskbar. He clicked the '+' button, and like magic, a new port named "loopMIDI Port 1" was born. loopmidi windows 11
In the Windows environment, a single hardware MIDI device can typically only be accessed by one application at a time. This limitation prevents you from, for example, using a MIDI controller to drive a DAW and a standalone synthesizer editor simultaneously. loopMIDI solves this by creating . These act as "invisible cables" that allow you to send data from one app (the output) and receive it in another (the input). How to Install and Set Up loopMIDI Setting up virtual ports on Windows 11 is straightforward:
Here is everything you need to know to install, configure, and optimize loopMIDI on Windows 11. What is loopMIDI and Why Do You Need It?
The new port will instantly appear in the upper ports list and become available system-wide. Removing a Port To help tailor this setup to your specific
So, what should you do?
Virtual routing is fast, but adding "plumbing" can add roughly 10–13ms of latency if used with complex Bluetooth workarounds.
When you play notes or run a sequence in the sender app, the data travels smoothly through the virtual loopMIDI cable straight into your DAW instrument. Troubleshooting Common loopMIDI Issues on Windows 11 You want to use it with
Locate "loopMIDI Port 1", turn the input , and enable "Track" or "Remote" depending on your needs.
Playing a standalone software synthesizer or standalone sampler using a separate MIDI sequencer or tracker.

: Built directly into the Reaper DAW for internal routing.
Ensure your DAW is using a dedicated ASIO driver (like your audio interface's native driver or ASIO4ALL) instead of the standard Windows MME or DirectSound drivers. Summary of loopMIDI Advantages System Footprint Extremely low CPU and RAM usage. Port Customization
