Replacing the chip in the Mute Synth 4.0.
Make sure that the notch and dot point upwards! Otherwise your chip will die. Be gentle and take it easy, make sure all legs go in the holes straight. They have been straightened before shipping so do not need any pressure, just put the chip in the socket and push down gently.
The music is straight from the Mute 4.0 with Radical Chip.
