How to Convert an MP3 to a MIDI Online
Using free online resources you can convert your MP3 files to MIDI files to be used to mix your own music or just to entertain your friends.
MIDI files, once a staple of online and computer-based music, are not as common as they used to be. Finding a free online conversion utility that can change MP3 files to MIDI format can be difficult. When you do convert your MP3 file to MIDI format, don't expect it to sound the same. For most tracks, the MIDI may sound like a cat prancing on a piano, regardless of what instruments were used to make the original recording.
