Atari Punk Console with CV inputs

Control Voltage (CV) inputs for experimentation with sequencers

Here is an Atari Punk Console with control voltage (CV) inputs.  The CV inputs could be driven by 4017-based sequencers.  

 

VR1 is a, Audio 100k potentiometer.  VR2 and VR3 are 500k Linear potentiometers
