Digitone USB host issues with older OSX

Hi,

I recently upgraded my Digitone to 1.31. In my studio I still work with Mac OSX 10.9.5 for a number of reasons. Ever since the Digitone upgrade my computer doesn’t see the Digitone in the Audio/Midi settings. If i connect the Digitone to my newer Macbook with OSX Big Sur (11.3.1) it pops up in the Midi Devices window immediately when connected.

My question: is it possible for older OS versions to still recognise the Digitone 1.31 as a Midi Device?

If not, i would maybe have to downgrade my Digitone, something I’m not looking forward to.

(Small sidenote, I also upgraded my Analog Rytm, and the Rytm is still visible as a Midi Device)
