Debugging Bluetooth MIDI note drops on Windows 11: A developer's journey with the Roland FP-90X
By
Erwin Mayer
Summary
A developer documents their frustrating experience with Bluetooth MIDI on Windows 11 after buying a Roland FP-90X digital piano. They discovered three separate bugs causing silent note drops between the piano and their DAW: Windows Bluetooth LE MIDI driver issues, MIDI SysEx message handling problems, and timing/queue bugs. Unable to find a working solution, they built and open-sourced a free MIT-licensed bridge application (Perfect-Bluetooth-MIDI-For-Windows) using Avalonia and .NET 10 that resolves all three issues. The post is a detailed debugging narrative.
