che io sappia non alla perfezione...
ho trovato questa guida per˛

NO program can do this properly..
Read on:

Basically, an mp3 file contains real, recorded audio. A MIDI file is just a sequence of instructions telling a player what notes to play, a lot like the little metal roll inside a music box.

There are programs that attempt to convert pre-recorded sound into MIDI data, but they only work well on individual melody lines, not full song mixes.

MIDI files of commercial songs are created by musicians and engineers who are skilled at re-interpreting a song into MIDI form, and it's not a process that can be done automatically.

A midi file can contain eight or more individual tracks with different instruments.
A stereo mp3 file contains only two tracks with multiple instruments mixed down from the original multi-track recording.
They cannot be separated into the individual tracks required by the multi-track midi format nor can the mp3 format be accurately converted to midi format.


Audacity 1.3 has a convert to midi function but don't expect perfection. I haven't tried this so what you get is what you get.

Download and install Audacity to your computer. There are separate download links for Mac and Windows computers, so be sure to click the correct one. Make sure that the version you download is at least version 1.3.6, as that is when MIDI export capability was added.

Launch Audacity on your computer. Click "File" and select "Open" to open up your MP3 file in Audacity.

Click "File" and then "Export" once the MP3 file is open. This will open the "Edit Metadata" dialog box. Click "OK" to move to the next screen.

Locate the "Format" field and click on the pull-down menu. Select "Other uncompressed files" as your output type. Click the "Options" button to the right of this field. Select your MIDI output type and click "OK," then click "Save" to convert the file. A screen will pop up as it converts, and you will see a progress bar on the screen. Once the conversion is complete, the screen will disappear. Look for the MIDI file in your Audacity folder.
