Basically, we just need to add a setting screen to H9 Control that will allow you to select a Core MIDI device, have the app read from the MIDI port and write out the data over Bluetooth. As you said, everything else is already there for the H9 to receive MIDI over Bluetooth. It's just one piece that is missing. And as I mentioned in my previous post, we are planning on adding this and it should be in the next release (unless something comes up and we have to do a quick bug fix release in between for some reason).
