Wave files (mp3s) are digitised sound waves. Midi files are sequences of
notes which are fed into a synthesizer, usually your soundcard, which 
reproduces the music. No doubt you already know this...

I have seen and used software (some time ago) which attempts to convert 
wave files to midi data, however it only produced one channel of midi
which
is essentially useless unless you are a composer trying to extract a 
sequence of notes from a small piece of music.

I think you will find it very difficult to find an application which
does 
this properly, let alone a python module.
