Re: [linux-audio-user] midi definition

I would like to have a better knowlege about the midi protocol, to understand better what is stored in a midi file and how it is stored. I am not that much interested in bits and bytes, but in how a description of a note works in midi, i.e. is a note defined by a start point and a duration ( and the end point is a consequence) or is midi a start and an end point ( and the duration is a consequence). What is a pause? Is it a silent note? How does a notation application calculate ties or what remains of tied notes? The duration only? And so on... If anyone of you knows some URL where to find usefull information about the theme in question, I would like it very much to see it posted here. If it is in german, even better ;-)
