Good point - but running status (by definition) only works when you happen to deal with multiple events with the same status. (That is, same event type and same channel.) In real life, that means you get 3 bytes for the first note in a chord, and (if you're lucky), 2 bytes for each of the following notes. Though this can save bandwidth and reduce latency slightly at times, you can't really rely on it in any truly useful way in this context. //David Olofson - Programmer, Composer, Open Source Advocate .- Audiality -----------------------------------------------. | Free/Open Source audio engine for games and multimedia. | | MIDI, modular synthesis, real time effects, scripting,... | `-----------------------------------> http://audiality.org -' --- http://olofson.net --- http://www.reologica.se ---
