Actually, form what I've read, I don't think MIDI 2 requires any (or very many) changes to Portmidi as Portmidi wraps the various OS-level MIDI APIs and gives you raw bytes. The actual MIDI protocol interpretation is handled in the Pd core.
MIDI 2 is basically an extension of the MIDI 1 protocol and MIDI 2 messages can contained embedded MIDI 1 messages. There is an additional query communication where a device can ask about the capabilities of another device. Overall, it seems to be designed to work seamlessly with older MIDI 1 devices/software.
Short answer is: I don't think anyone is doing this, but it can probably been done by modifying MIDI handling in s_midi.c.

Hi all,
Is there any plan to support MIDI 2.0? I know this is more of a question about PortMidi, but I was wondering if anybody knows anything about it.
Cheers, Mario

Hi Dan,
Thanks for getting back to me. Yap, I had a look at the protocol and is like you said about retro-compatibility. I'm glad to hear that probably can be dealt with making some changes in s_midi.c, work that of course I know still takes some efforts. My question though, was more related to the new msg introduced by MIDI 2.0, with a different structure and resolution. But I suspect what you said is valid for that as well, right?
Cheers, Mario

Mmm my initial thought is that the existing objects can simply send out a more finer grained number. Design-wise, I think we would want to utilize as many of the existing objects as possible, ie. input/output MIDI 2 range, maybe add messages or creation args for special MIDI 2 modes. This could also require some sort of new object as well. The best design would not affect patching between MIDI 1 and MIDI 2, if possible.
For now, though, I think MIDI 2 could be implemented at the patch level using the raw MIDI bytes from [midiin] and [midiout]. It would probably take some doing, but MIDI 1/2 are basically just raw bytes and the notion, ctlin, etc objects a result of interpreting the protocol.
