Eurorack Envelope Generator ADSR DIY Kit/PCB

This module is part of my Eurorack series. It is an envelope generator based on the 7555 timer integrated circuit. An envelope generator creates a control voltage that is usually used to shape a sound over time, e.g. in a voltage-controlled amplifier or filter. It sounds more natural than just turning a note on and off.
