Basically all MIDI is is Note On at X time on foo channel, Note Off at Y time on foo channel. Duration would not work as a property of the Note On, as MIDI has to function in real time - when a piano player hits a note you have no idea when he/she will release it. The easiest way to see this is to run aseqdump and then play at a MIDI keyboard. You can see in real time what the MIDI representation of anything you do is. Lee
