Why MIDI and not MP3
files for audio?
There are a number of reasons for choosing MIDI over MP3 for
jam tracks, but the main one is simply load time. In MIDI format,
a 2-3 minute trio jam track is perhaps 30 to 50 kilobytes in
size, like downloading a small photo. In MP3 format, the same
file might be as large as 3 megabytes, which obviously takes
much longer to download, regardless of high or low access speed.
MIDI is also a FAR
more flexible medium, in that the user can download the audio
file, then make personal changes regarding tempo, key, instrumentation,
etc, in even the simplest of MIDI sequencing programs.
