I don't have any experience with the WidiBud yet, but it seems like everything you've described should work. If you go to "About your PC" in Windows 10, what version are you currently running? I just want to make sure you are running a more recent version, as some of the MIDI functionality in Windows (for applications that use Microsoft's UWP MIDI framework like MobileSheets) depends on later updates. Just to verify - you said you are seeing MIDI messages being sent and received when you use the Widi Plus application? What about if you use a simple MIDI monitor in Windows (like MidiOX)?

If we can't get MobileSheets to connect over USB to the WidiBud, another thing we can try is setting up a virtual MIDI port through which MobileSheets communicates using an application like loopMIDI.

Thanks,
Mike

It works fine now, just forgot to set up midi parameters on my Line 6 Helix.
