The module is, just like in the old video games, a linear feedback shift register that uses very little hardsware. It generates 12 sounds ranging from simple square wave to white noise with all other classic arcade sounds inbetween.
A 1V/octave input allows fr playing the oscillator tonally. Instead you can also use an external clock to drive the shift register´s tempo and thus the oscillatros´frequency.
Tone CV input, 1V/octave input. oscillator output
3U Eurorack module, 4HP wide, 26mm deep.
Current draw: less than 50mA@+12V and less than 5mA@-12V
