I've seen quite a few adverts for MIDI2 keyboard controllers now, so has anyone
tried interfacing with this yet?
If so, what sort of problems have you had to resolve.

Hey Will,
tl;dr: it should work without issues, just don't expect DAW/plugin
support for MIDI 2.0-only features yet :)
ALSA has pretty good support for USB MIDI 2.0 from Linux 6.6 on
(rawmidi + seq) [1][2], translating transparently between MIDI 1.0 and
2.0/UMP. Obviously you'll loose precision and maybe a few features
translating from MIDI 2.0. So far I only tested with a RasPi Zero 2
acting as a mock MIDI 2.0-only device [3], I'd expect "real" MIDI 2.0
controllers will present as both legacy USB MIDI and USB MIDI 2.0, so
you'll see duplicate ports in your DAW on recent kernels and legacy
only on < 6.5 kernels.
Regarding everything above ALSA:
- JACK doesn't have a special port type for UMP and using the existing
MIDI ports for that feels weird (byte buffer vs. packets etc.), so
let's wait for/make that happen
- no free DAW yet with MIDI 2.0 support
- VST3 and CLAP already allow high resolution parameters and note
expression by their own event abstractions, however this is useless
without DAW support
- CLAP plugins can also interface MIDI 2.0 directly
- LV2 currently limited to MIDI 1.0
- WINE doesn't implement the new Windows MIDI Services yet

Sorry, quick correction
you'll see duplicate ports in your DAW
was wrong, as the kernel doc explains:
When a device supports MIDI 2.0, the USB-audio driver
probes and uses the MIDI 2.0 interface [...] as default instead of the MIDI 1.0 interface

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
