MIDI broke again this week despite having stopped Windows updates - and seemed like nothing got automatically updated without my OK. Seems like its all due to the Windows 11 MIDI 2.0 updates - issues with are discussed here: https://devblogs.microsoft.com/windows-music-dev/windows-midi-services-rollout-known-issues-and-workarounds/ On that discord discussion a recent update allows for rolling back the MIDI 2.0 to legacy while still keeping Windows up to date: https://microsoft.github.io/MIDI/kb/how-to-change-api-mode/ I've updated Windows and set the MIDI API Mode to Legacy, and all is well. Somewhere on the Discord was mentioned that a big drop is expected in November which may address the bug with the Helix and other devices that aren't 'Class Compliant'.

Was working for me fine yesterday, then not today. MIDI over the MIDI cable was fine. All other MIDI USB controllers I have were fine. Triple checked the settings on the Helix. Using MIDI tester: https://hardwaretester.com/midi in case it was my DAW or its settings. Rebooted the PC and restarted the Helix. None of it did anything to help. Until I rolled back the latest security patch from yesterday: KB5101650 Now it works fine. (Until the next patch?)
