Digital signal controller

A digital signal controller is like a special computer that can do really cool things with music and other sounds. It takes in electrical signals (like from a microphone or guitar) and uses fancy math to change them into something that sounds better or does a specific task (like changing the pitch or volume). It's kind of like a special tool that helps music makers create and control sound in a more precise and fun way.
