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.

He typed: "Can you understand me?"

: Virtual ports only exist while the loopMIDI application is running. If you close the app, the "cables" are effectively unplugged.

While Microsoft’s new built-in loopback endpoints are designed to replace tools like loopMIDI, the native service is still in a "controlled rollout" phase as of early 2026.
