MIDI addresses a broader category of problems where there might not necessarily even be an audio stream. Not unusual now, I have an analog desktop synthesizer module with a MIDI-to-CV control interface, and I simply want to connect a MIDI keyboard to it to be able to play it. My application is unconcerned with digital audio streams. Actually, I have a bunch of synthesizers, some analog and some digital. I use a hardware sequencer to sequence them. Some use their own internal sequencers, so they simply use the start/stop/clock real-time messages to stay on beat. The point at which any of this becomes an audio stream is if I start my PC and record from the mixer output. MIDI 2.0 at least opens up to some improvements to synchronization with fine grained event timestamps. Using that together with timestamped audio buffer delivery at least allows for jitter mitigation.
