Has anyone used intelliscore (itelliscore.net)to convert MP3 files to 
MIDI? Could make for a lot of great piano solos.

I just downloaded the demo version of it and tried it on a couple of
tracks- Stevie Wonder's "You are the Sunshine of my Life" and on a
recording I made from my DKV of one of Terry Smythe's roll transfers "Five
Foot Two".

CAVEAT: I have not tried configuring the program, other than using their
wizard. It is quite likely that better results can be achieved than I got
in my quick test.

Anyway, the first was a disaster. Stevie would not be able to recognise
the song at all.

The second was a bit better, so I've uploaded a portion of the mp3 and the
resulting midi file. You can just about recognise it.

Automatic polyphonic transcription is still being heavily researched. It
is a very very hard problem, IMO and unlikely to be solved well any time
soon. At least humans have a roll in music for a little bit longer :)

These should have been:
http://www.jamesfry.com/music/fivefoottwo.mid  - midi file
http://www.jamesfry.com/music/fivefoottwo.mp3  - mp3 file

My apologies!

Here is another one to try. Hopefully a good version can be found to 
capture all that is recorded other than on rolls.

As Midimagic says, this is really a fantasy. This kind of task is
extremely difficult and is the subject of much research. Nobody really
knows how the human ear can identify all the different notes and
instruments that are playing at any one time in a piece of music which
makes it quite hard to try and model.

Some approaches work to a degree, but not very well yet. If you have a
relatively good model of each instrument you can analyse the frequencies
present to work out which notes are playing, but this is hard. You can
also perform things like independent component analysis, but this is
really only any good for separating out individual parts from a mix and
requires you to know how many signals were used to begin with.

Sadly, it isn't going to happen any time soon. The best way to capture
performances from audio recordings (at the moment) is to sit there and
transcribe them.

Listening to music, then writing it down (transcription) is like knowing how
to read then developing an interest in grammar.  MIDI also gives us some
very powerful tools to aid this process in that it is like a word processor
for music.  I started to learn how to do music transcription myself last
year and found reading the book, "How to Play the Piano Despite Years of
Lessons", available from www.amazon.com to be an excellent primer on the
structure of music.  You can use your ears to find the bass line in a song,
then use a software program like Band In A Box with its intuitive chord
mapping to create a MIDI file.  I am looking forward to the coming year and
finding more time to play with this!
