Access Key: METAHACK2026 Live: https://mixray.vercel.app/?key=METAHACK2026 Mixray: point at a sound, hear it alone, learn to play it. Drop in a song or a video, then pick one sound out of the mix by drawing around it in the video, typing its name, or tapping a chip Muse Spark suggests. Mixray separates it, reads its tempo, key, chords and notes, and teaches it on any MIDI keyboard: the rest of the track keeps playing while you fill in the part, every bar is scored, spoken commands slow it down or loop a bar so your hands never leave the keys, and a coach points at your weakest bar. If a sound isn't in the audio, Mixray says so instead of making one up. Everything exports as MIDI, the separated audio and a suggested starting patch. I built it because I've loved EDM since 2017 and most of the evenings I spent trying to play a melody I loved ended before I played a single bar.
