Back of envelope: With running status, a note on message is two bytes on a 31250 baud connection. That means the latency from transport is on the order of half a millisecond. If you’re feeling latency, it’s in the gear, not the protocol. MIDI implementation quality has long been wildly inconsistent, and I don’t see a reason to believe that will change with MIDI 2.0.
