Is this possible? I mean, I know it's possible but is there a good convertor? Can you tell me one that you've tried and seemed good?

MIDI to MP3 is possible, but MP3 to MIDI? I don't see how that's possible.

Trying to make a bundle on ringtones?

You have to understand what MP3 and Midi are before asking such a question. A midi file is an electronic representation of notes to play to achieve a song. The notes are coded into something called a wavetable that has become relatively standard overtime.

MP3 on the other is a waveform that is compressed to take less space and is not considered a series of notes, it's the exact sound (or nearly) that must be sent to the magnets forming the speaker.

To be able to transform mp3 to midi, you'd need to analyse the MP3 at several points and detect the tone of the notes played and transfer them to an electronic midi note which is almost impossible. Reverse is possible though!

If your goal is to make ringtones like the previous poster said, then you should think about the newer ringtone formats that are not MIDI files but waveforms (highly compressed but nevertheless, they are waveforms)

Thanks for the help guys.
I know what MP3 and MIDI are. By saying that I know it's possible I meant - there are converters. But as we know, they aren't very good. So I was just hoping that there is a good one. And that's why I asked you.
I had an idea for a software, but I needed the music to be stored in a MIDI file or somthing of that kind. I needed it becouse it's 'an electronic representation of notes to play to achieve a song'. I don't need the sound itself.

Have you tried looking at what the Linux commands, ffmpeg or ecasound, can do for you?

Hmm... I'm not much of a Linux fan, but I'll have a look. Thanks.

I would recomend whomever is thinking of such thing to clear that ideia from his/her head.

That question is kind of like : "picture of a house to blueprint". It's not mathematically impossible, but it doesn't make real world sense, at all.
