Note:	These days most film songs and popular recorded music is written and performed using electronic keyboards and other MIDI-equipped musical instruments. Recently MIDI has begun to be used to generate ring tones in mobile phones. MIDI ring tones sound far better because they are polyphonic  and because they use music synthesizers which produce a wider variety of sounds than possible before.
	Karaoke music produced by ragatracks is played in music synthesizers and then it is edited directly in computer using music software like Cubase sx3. Music synthesizers are attached to computer using usb interface. Later we can mix our voice  with the karaoke music and  our  own CD is ready.
