I use a CME WIDI master, which works brilliantly and powers from the roland ax-1 batteries
few pointers
download and install the CME WIDI app
make sure you rename the device here otherwise when it reboots it will default to the default name
Set BLE role force peripheral (to computers)
set other to as I’ve done or to preferred settings
open Gp and select the Names Bluetooth(ax-1 in my case)
I have all my keyboard’s MIDI blocks in the global and pass them through the global out to Rackspace. I set each device to a different midi and then use the constrainer’s to map them internally to any channel I want via widgets.
once in the local rackspace, I remap via widgets to any of the 6 synth slots I’ve set up so I can have song variation switch keyboard splits and synth maps to suit.
hope this helps others.
I’m also using the CME WIDI Uhost for my BBC2 breath controller and WIDI Master for FCB1010 foot controller, naming them in the WIDI app makes it easy to manage.

Damian
