Hello,
First, I would like to thank you for this external.
However, I recently found that it doesn't identify my Morph with a Bluetooth connection.
It does identify it with the micro USB cable, but not with Bluetooth.
I tested this with Pd-0.51-4 and Purr Data and none seem to work.
I'm running this on a 2012 macbook with macOS 10.13.6
Also, MIDI over Bluetooth works just fine with an overlay.
