Turn your game controller into a musical instrument & create full songs with JoySynth! JoySynth is a Windows music application that transforms a USB game controller into a complete playable instrument. Use the analog sticks to select chords and notes, press the shoulder buttons to play, add drums with the D-pad, and build complete songs using the built-in loop recorder. JoySynth is designed to make creating music immediate, visual, and fun—even if you’ve never played a traditional keyboard.
