So I checked the article
I wasn’t familiar with the issue, but now I see It says that it may happen after a disconnect because the old API doesn’t handle disconnects gracefully. That I do know.
If you’re not unplugging USB devices, I would think it’s possibly a virtual device connection, like VEP, that is being released before Cubase tries to send the closing SysEx to it.
For WinRT MIDI, it may be you’re out of MMCSS threads (incoming MIDI data uses them in the WinRT API). Steinberg has an app to apply the registry change to increase the number of threads.
WinRT MIDI and the new Windows MIDI Services (Overview | Windows MIDI Services ) both provide device disconnect notifications, so this will eventually go away when apps move to the new APIs.
