Show HN: Perfect Bluetooth MIDI for Windows
Erwin, a developer, created a free open-source tool called Perfect Bluetooth MIDI for Windows to enable reliable Bluetooth LE MIDI keyboard connectivity with Windows 11's MIDI Services stack. The utility resolves issues preventing DAWs and Web MIDI apps from recognizing or communicating with Bluetooth MIDI devices like the Roland FP-90X. It uses a loopback system to bridge WinRT BLE-MIDI input to Windows MIDI Services and includes a channel detection feature to fix silent note reception.

On my Windows 11 PC, pairing succeeded, but my DAW couldn't see the keyboard, and notes I sent from the PC never made the piano sing. After a regrettable number of evenings, I'd separated this into three independent bugs stacked on top of each other.The first one is the famous one: Windows only natively exposes BLE-MIDI through the WinRT API, which almost no DAW polls. So even when pairing succeeds, MIDI apps still don't see the device.
