The MUSIC MACHINE cartridge you have purchased allows you to play your Commodore 64 computer like a musical instrument, using the music synthesizing capability of this computer. Your computer keyboard is
transformed into a synthesizer keyboard, complete with percussive accompaniment.

The cartridge has been designed with flexibility in mind. Rather than having the variety of musical tones being one of a number of preset selections, there are a number of parameters you can mix and match, allowing you many combinations of sound type, special effects, and keyboard playing style.
