Hello Dan,
Would you consider implementing Bluetooth MIDI support?

If this is possible , it would be very useful for using iPad as controller etc.
without having to use Wifi or cable.
Bluetooth LE works very well with virtually no latency.
It is possible, there are many Bluetooth Midi Apps
for iOS, Android and WinPhone.
I am waiting for my Yamaha UD-BT01, which will make any of my USB midi controllers/keyboards wireless. The problem is that Yamaha has not written a driver for Windows. If vArranger 2 supports the new Windows Bluetooth midi protocol, it will make connections more simple and flexible.
Windows 10 has added support for MIDI Bluetooth, but not available for standard windows programs. Only on their new "Universal" apps.
It should be possible to use a Windows Store app that receive the midi bluetooth, and send it back to a virtual midi cable like this one :

I tried out the Yamaha UD-BT01 with my Windows 10 machines. No Windows driver for the UD-BT01. I used the two bridge apps Dan mentioned. Too much latency as before when I had tested at different times. Then I paired the UD-BT01 directly with the built in Bluetooh of my Windows machines, which was picked up by Sonar in the new Windows MIDI protocol. The latency was as bad.
So far, only the Korg BLE devices/keyboard controllers with its own Windows driver worked the best. Or any BLE transmitter paired with the WIDI Bud worked very well with no discernible latency.
