In a a recent blog post on the Windows Developer Blog by Pete Brown - hes the guy we spoke to last year about new audio and MIDi capabilities in Windows 10, we're told that MIDI over Bluetooth is now possible with the Windows 10 Anniversary update. its in the form of Bluetooth LE MIDI, a standard that Apple are also adhering to. Its been added as a new transport referenced in the MIDI APi, which means that there are no code changes required to access it.
Presumably this will mean we will see more MIDI applications coming to light as had happened in Apples proliferation of Bluetooth MIDI support, most notably, perhaps now we'll see hardware such as the new Korg NANO and MICRO units. Whats also interesting is that this will be able to access any Bluetooth LE enabled Windows devices - phones, tablets, PCs etc.
When paired, the Bluetooth LE MIDI peripheral will show up as a MIDI device in the device explorer, and will be automatically included in the UWP MIDI device enumeration. This is completely transparent to your application.
We don't pretend to know the full ramifications at a coding level for these developments, but what it does show is the intent of the Windows 10 team to continue to encourage audio and MIDI application development by third parties and make it simpler where possible.
