Housed in an early surround sound mixer made by Victor, this synthesizer is based on the stepped tone generator designed by Forest Mims, also known as the atari punk console.
X (up and down) controls the frequency and Y (left and right) controls the pulse length. The original volume control is used. The large white button (also salvaged) is power and lights up when on. It runs off an internal 9v battery and has a standard 1/4″ inch output.
