Bounce is a full music studio in your pocket — start from a prompt, a sample, a song you want to flip, or a blank session, and every piece stays yours to edit. SHARE IT — NEW Turn any project into a link anyone can open and play — no app required. They tap to listen, then "Open in Bounce to remix" drops the whole editable project on their timeline. Export a vertical video for TikTok/Reels in one tap, with a reactive visualizer. Invite a friend and you both get credits. START BY TYPING A VIBE — NEW First launch: describe what you want — "dark drill in F minor," "sunny afrobeats" — and a full, editable project is waiting for you. FLIP IT — NOW IN TEMPO Pick any song and Bounce pulls it apart: vocals, drums, bass, and the rest, each an editable track. New in 2.9: Bounce detects the song's tempo, so the stems land in time and follow the project's BPM. (Flip music you have the rights to use.) PLAY & CHOP — NEW SAMPLER The Perform pads got a redesign: a waveform strip shows your sample, drag the chop points wherever the hits are, and each pad lights its slice as you play. SPARK — FROM PROMPT TO PROJECT Type what you want and Spark builds a full, editable project in seconds. Re-roll any part and it stays in key and in harmony — even after you close the app. TALK TO YOUR PROJECT "Make it darker." "Re-roll the drums." "More reverb on the melody." Every change undoable in one tap. BOOTH — RECORD VOCALS Lyrics on screen, takes, comping, punch-in, vocal tune, one-tap vocal chains. PLUS THE FULL STUDIO • Multi-track recording, tempo-synced loops, cycle playback • A real mixer with honest meters + auto-mix that listens • AUv3 instruments and effects, Bounce Sampler • Generate a Sound & Sing a Hook (editable AI clips, credits) • Export a finished mix, stems, a social video, or a shareable link What you make is yours.
