Cubitton Tshirt 5000

Cubitton Tshirt 5000 is a tiny music studio that fits in a browser tab. Pick a starter track, hit play on any clip and build a song by launching loops in time: every clip starts on the next bar, so it always sounds right.

Click squares to paint drum beats, draw basslines and melodies that stay in key whatever key and scale you choose, and shape every sound with knobs. Then perform it like a DJ: an FX unit, a three-band EQ on each deck, beat roll and a crossfader between two sides of the mix.

Every sound is synthesized live, so there is nothing to download, and your project saves itself as you go. Five studio looks, a guided tour for first-timers, undo and redo. Headphones recommended.
