Linux’s sound subsystem maintainer Takashi Iwai has recently published Linux driver patches for MIDI 2.0 support for the USB Audio and Raw MIDI drivers, expected to be included in the upcoming Linux 6.5 cycle. The new MIDI 2.0 driver supports higher resolution and better articulation, as well as an easier way to transport MIDI messages with the Universal MIDI Packet feature. The patches were reviewed quickly by Takashi himself, and have already been queued up for the Linux 6.5 merge window opening at the end of the month. MIDI 2.0 is a major change to the widely-used MIDI protocol, and the patches are expected to premiere later this summer.
