Most midi files were created in Guitar Pro 3,
a real groovy tablature proggie for cyber-jammers
(I could list all the problems it has, but it's still cool).
Older midi files were created note for note in Cakewalk
(no actual instruments were used in their construction).
The parameters of midi provide for exact reference in time
but sadly tend to deny the listener of the actual experience
~ as most cool rock sounds have yet to be fully incorporated
and most cool rock tunes aren't even close to in perfect time ;o)
Therefore, any resemblance to actual music, carnival noize, or even video games
is purely coincidental `n probably a property of your web-browser's midi plugin =o?
