Hey Product Hunt! 👋 I’m Eric, the creator of JoySynth. I built JoySynth because I wanted to see whether a familiar game controller could become a genuinely playable musical instrument—not just a novelty button mapper. The analog sticks select chords and notes, the shoulder buttons play them, the triggers bend pitch, and the other controls handle drums, instruments, effects, scales, and recording. JoySynth has grown into a complete standalone Windows music app with layered looping, custom samples, microphone effects, live audio inputs, a sound-board mixer, and performance recording. The first public version is currently free to download. I’d especially appreciate feedback about controller compatibility, how intuitive the controls feel, and what features or sounds you would want added next. Thanks for checking out JoySynth!
