Hi r/ableton . Sharing a small free open-source Windows utility I built. Solves a fairly painful gap between Ableton and Bluetooth MIDI keyboards on Windows.

The problem: pair a BLE-MIDI keyboard with Windows and Ableton just doesn't see it in MIDI preferences. Cause is that Windows only natively exposes BLE-MIDI through the WinRT API, which Ableton doesn't poll. The classic answer is MIDIberry + loopMIDI, which works but is fragile (the 20-second-disconnect bug bites a lot of people).

The app does the BLE side directly and routes the keyboard through the new Windows MIDI Services loopback so Ableton just sees a normal MIDI input.

I built it for my Roland FP-90X (which is what I've personally tested). Should work with the rest of the BLE-MIDI ecosystem, but I haven't confirmed.…
