You can view an online version here. This is a very in depth article explaining Musical Instrument Digital Interface, otherwise known as MIDI. It was developed over 20 years ago now, as a way for synthesizers from different manufacturers to be able to communicate easily.
Before reading this article, I didn't realize just how much there actually was to MIDI. Sure I had heard the term and understood that it was a digital music communication tool and even learnt a little bit about it in another unit I studied, but I never really took much notice of it!
I particularly like the fact that you can play around with the tempo with a MIDI and this wont affect how the music sounds. If you slow down or speed up a normal audio recording you end up with music that sounds like its from another planet. MIDI's can be slowed, or sped up, with no alteration to the pitch, which is fantastic!
I think that most people would think that MIDI is sounds or audio that travels through the MIDI cables, however this it not true. MIDI is really a system of sending instructions between MIDI devices. So if you play a 'C' on a keyboard, an instruction is sent that the c key has been pressed and the same when you stop pressing the key. The simple "note on" and "note off" instructions tell the output device what to do. Even how hard you press the key is detected and the information sent through to the device via a 5 pin MIDI cable.
