concept1: reactive music video player

[concept]

The player processes music video automatically when I input codes of music.
music code's FORM is borrowed from an online game.
That code is used in the game as a music score to play.

The form of code is:

a~g: la~sol musical scale
r: pause
#: sharp
numeral: length od the note
<,>: octave moving

I'll use this strategy to incode a music.
