I see that there is a prototyping development system for MIDI 2.0 systems, along with the A2B which provides for thirty-two digital audio channel connections. The prototyping system is called ProtoZOA. ( One of those cutesy industry sort of names. )
I posted about the use of A2B for MIDI 2.0 in the MIDI 2.0 thread.
ADDED : Looking at the AmeNote ProtoZOA web page, i’m not seeing specific mention about A2B. So i am a little confused, as it is mentioned in the Synth and Software article. Perhaps there will be clarification on this after the NAMM announcement. The ProtoZOA is available to the public in Q4 2022, and to members of the MIDI Association and the AMEI now.
