You cannot decompose an .mp4 file. The only thing you can do is trim the sound clip to pieces.

Using .mp4 it is impossible. Have you thought of using midi? – Nikos M. Nov 13 '13 at 14:02
.mp4 is not compulsion. i can use any format..please tell me if its possible with any other format. – Sakhare Nikhil Nov 13 '13 at 14:05
