Hi H9 GW people,
I was just setting up the scenario where my H9 is being remote controlled by my Gtr Wing.
The setup includes the H9 control app on my iPad with Blietooth MIDI LE running on the iPad.
Afaik the H9 pedal needs an iOS device or a computer to serve as the Bluetooth MIDI host and the pedal and the Gtr Wing are clients.
Hope this helps… Google searching is a must for my success!
