Indeed, right now there is no production release of Virtual MIDI ports on Snapdragon.
Microsoft is in the midst of a complete re-write of the MIDI drivers which will include ARM (Snapdragon) support. This is in alignment with their MIDI 2.0 development effort.
As I understand, Microsoft has a preview build for developers (Canary) and I believe they are planning on releasing for general availability later this year. Once the new drivers are available, we plan on testing and potentially integrating with Bome MIDI Translator Pro .
