MIDI 2.0 driver support coming with Linux 6.5
As a composer software engineer: all I can <i>personally</i> say is that MIDI is a pretty terrible protocol that's borderline unusable for everything except very limited applications. It's fine to use it for keyboard (piano, organ, celeste, harpsichord etc). For literally anything else it's useless and I see nothing in 2.0 that fixes it.
