Does anybody know if Axoloti supports Midi 2.0? Among other things, one of the most attractive qualities of MIDI 2.0 are bidirectional communication and continuous controllers with several bytes of accuracy (not just 128 different values, instead now there are thousands)
Does Axoloti support this natively? Or if not, is there a way to get this to work?
As far as I know it does not support midi 2.0.
Last Axoloti release was April 2018, midi 2.0 is only just getting out.
Axoloti is also slowly entering a new 2.0 stage, with a lot of updates, but didn't see midi 2.0 in there unfortunately. Who knows maybe midi 2.0 will be added in the future 
ProtoZOA by AmeNote is the official MIDI 2.0 spec development board from the MIDI Association. Featuring a dual Raspberry Pi Pico combined with a CME WIDI Core it is supported by a suite of open-source firmware and software. https://amenote.com/?page_id=74
