[sdiy] MIDI Clock sync advice

[Mike Bryant]

MIDI-2 is transport agnostic, but USB was one of the transports considered - i.e. all forms of USB.  There's a chart somewhere showing what you get for each USB speed.

But the timing issue that people keep mentioning here as a problem with MIDI over USB totally goes away with MIDI-2.  That was always going to be an issue trying to kludge something designed for a specific transport onto USB.

No idea on Apple but there is a full pre full-release support for MIDI-2 from Microsoft on Github.  Apple, Google and Microsoft worked together on Network MIDI-2 so no technical reason there shouldn't be.

MOTU are a full MIDI member so will have been involved all the way, and have already put some MIDI-2 features in Digital Performer.

Interesting.

I had the impression that MIDI 2.0 was completely independent of USB. Although I noticed a *lot* of press about MIDI 2.0, I never saw many details (other than some mention of two-way protocols that would allow editors to know that a specific synth is attached to the other end of the MIDI 2.0 cable).

I am also unaware of any new USB-MIDI specification ... it's still pre-USB 2.0
I there a new USB-MIDI spec on the USB.org site?

Are there any USB-MIDI products shipping that have this new MIDI-2 with proper USB? More importantly, does Apple macOS have USB Class compliant drivers for such interfaces?

Finally, how does MIDI-2 USB compared to MOTU MTP? Were MOTU involved in consulting on the new specifications?
