[BUG] Loopback MIDI Transport not installed with Feb Insider Canary Customer Preview 1

[Psychlist1972]

The loopback MIDI transport, which allows end users to create loopback endpoints, was not installed with Customer Preview 1. The files are there, but the required registry entry in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows MIDI Services\Transport Plugins is not.

If you want to use Loopback endpoints:

1. Create an entry in the Transport Plugins registry key. Call it Midi2LoopbackMidiTransport
2. Inside that, add a string value named CLSID
3. Right-click that and choose modify
4. Set the value data to this string {942BF02D-93C0-4EA8-B03E-D51156CA75E1}
5. Add a DWORD property named Enabled. Double-click it as above, and set the value to 1
6. Open the Services app
7. Find the Windows MIDI Service
8. Right-click and restart the service
9. If you have the SDK runtime installed type midi enum transports and verify the LOOP transport is present
