I've searched at VersionTracker but I can't find anything that fits the bill. It seems possible to convert a midi file to mp3 or aiff but not the other way around.

no way man.

that is like converting a rendered image into a wireframe.

Really? Isn't a midi file just a specific type of audio file or is there something special about it?

MIDI is the combination of notes required to play a song, things like note, duration, instrument, etc. MP3 is a representation of the waveform that those notes generated when played.

It's not possible. When you learn what a MIDI file is, you'll understand why.

MIDI doesn't record actual audio; it's data that tells a computer to play certain notes and instrument sounds. It's basically like sheet music for your computer.

actually it IS possible.

maybe it's possible, maybe it's not. it if is then it probably won't be very accurate. an app that turns audio into midi is only guessing.
a MIDI file is, basically, a text file that says "play note A sharp 3rd octave at this point in time." it is NOT an audio file. it's a set of instructions that tells a synthesizer - software synth, hardware synth, cellphone - what noises to make and when to make them in relation to other noises.

Exactly

In case the explanations above are a bit confusing:

MIDI is the sheet music.

mp3 is the finished recording.

The only way to go from the latter to the former is by manually transcribing every note.

Melodyne CAN do this (and made a huge splash when it hit the market because of it), but ONLY for monophonic (single-note) signals. The minute an instrument plays two notes or you add a second instrument, Melodyne fails. (Note that creating a MIDI file from an audio signal is not Melodyne's intended primary purpose; that's more of a side-benefit to the way the software works.)
