If I'm not mistaken, FBV express doesn't use an app to convert signals into MIDI, it sends MIDI data itself, you just use the app to configure what type of MIDI messages are sent.  iRig Blueboad seems to have different behaviour and works as you described.

I can confirm after buying IK Multimedia iRig BlueTurn AND BlueBoard that they don't work in Windows...
The confusion (or hope) came with the "windows" program to update firmware... so you can do that on a PC but then there is no way you can pair the device in the system!
I got a credit when returning the stuff so I think I will Buy AirTurn products from the same store.
I thought I could have a 4 pedal device that looks nice for under 200$ but that was a dream!
