The physical layer operates at 3125 bytes per second which just isn't enough for anything more than a single instrument The typical MIDI 'instruction' requires 3 bytes. So, 1000 non-intense instructions per second. Not good enough for intense controller mods, but if the played 'instruments' do most of the work, that's over 80 ips (notes e.g.) for each of 12 voices. (Also that's 3125 bytes per MIDI input, of which you're welcome to use many.) Perfectly adequate most of the time ... and one reason that the original, genius design lasted this long. NOT to say that it isn't insanely great to hear this news.
