[LAD] Re: MIDI 2

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 [1] ALSA details: https://docs.kernel.org/sound/designs/midi-2.0.html [2] General overview (ADC 23): https://adc23.sched.com/event/1PueB (video not up yet) [3] https://gist.github.com/cbix/97a341c2857fd4f55d0cd19ccf6c354b Flo / cbix Am So., 17.
