Hi Azar,

Your question is, how to transfer mp3/audio to midi? Not midi to audio which is easy.
The short answer is no. here is why. But only partly, I hope it helps. The information in a midi file is note-on and note-off. THis note-on note-off is sent to channels on your synthesiser. These channels have sounds asigned to them. Piano, Organ, symbals drums and any other instruments your synthesiser or sound card have installed. So the midi signal information is sent to channel 7 on your sound/card or synthesiser. If you have a trumpet on channel 7, then the trumpet sounds. If you have a Drum sample, then the note-on information will sound the drum. The note-off signal stops the sound. Midi is sent via serial communications. The trouble is that it appears almost imnpossible to transfer the audio content which is waveform into a useable midi signal. There may be some clever software to do this, but where it is, how effective it is, are 2 questions to which I know not the answers. If you want a more in depth response, write me off list and I'll either help, or put you in touch to folks who really know what they are talking about on the subjects of MIDI and audio.
