This document provides instructions for circuit bending a CASIO VL-TONE keyboard. It lists the necessary tools, components, and gives step-by-step directions for performing various bends, including attaching wires to pins on chips to create new sounds, cutting resistors and adding potentiometers to control pitch, and adding a line out jack. Safety tips are provided and it is noted that batteries should always be used instead of the mains power when the case is open.
