Expandable ATtiny85 synthesizer, which acts as a basis for a mini modular setup.
The ATBase is the next level ATtiny Punk Console with an extended frequency spectrum into the bass range. Three red 3.5mm jacks now replace the body contacts. These can be used to manipulate parameters from the outside with control voltages of 0-5V. The trick with the red marked jacks is to lead out the supply voltage and simultaneously lead back the modulation signal via a stereo cable. This allows you to test your own CV circuits (e.g. super simple with 2 components: a resistor + light sensor) or connect noisio CV modules.
