convert instrumental mp3 to midi

[hue03]

i have several instrumental mp3s/wavs/etc with the only instrument being the piano. i want it to convert them to midis, but how do i configure everything in conversion softwares? i've read in these forums that midi conversion is rather difficult, but would instrumentals make it any easier?

midi to audio: easy
monophonic audio to midi: workable
polyphonic audio to midi: forget it

it's very hard to program a soft in a way that it can understand when a particular pitch is really played or if it's only a harmonic component of a complex tone...

example: play 2 sine wave that are at a harmonic major 12th apart. nobody nor no soft can tell you if it's a single sound or two note played separatly.

There exists a software application named Digital Ear which converts WAV to MIDI. If you can get it to work, do explain how.

Again, it's for monophonic audio...

[Adraeus]

That's what he asked for, right? He said he has several instrumental music files containing data for a single instrument: piano.

Piano is polyphonic!

Unless the recordings in question are of a one fingered pianist
playing "chopsticks for amputees", then the conversion is currently impossible. Maybe technology will develop down the line to accomplish this, but so far nothing can analyse a polyphonic audio source and regurgitate it as midi. The only way to do this would be to pay someone with a good ear to transcribe the material for you.
