Bounce vs Rithmatic

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.

Rithmatic is an FM synthesizer with 36,118 classic DX7 voices built in, and an AUv3 plugin for GarageBand on iPad and your DAW on the Mac. Browse them by family and by character, learn how FM works by watching it shape each one, build and blend your own, and play them from the on-screen keys or a MIDI keyboard. No account, no ads, nothing locked. IN YOUR DAW • Put it on a track in GarageBand on iPad, or in an Audio Unit host on the Mac such as Ableton Live. • Its window is the app's own Patches screen and Patch Builder, with your library. • Your bank appears as the plugin's presets, and Brightness, Attack, Decay, Release and Feedback can be automated. The patch is saved with your project. A LIBRARY THAT SHIPS FULL • 36,118 unique DX7 voices come with the app: no download, no account, no network. • Start with Essentials: the famous sounds and the songs they're on. • Browse by family, or by character: percussive, plucked, metallic, bright, sustained, swell, evolving, mellow. Or search by name. • Patch of the day: one classic voice each day, in the app and in a widget for iPhone, iPad and Mac. • Every voice is credited to the archive it came from, and to its designer where a bank names one. PLAY IT • A DX7-compatible synthesis engine runs inside the app, so every patch plays with nothing plugged in. • Play from the on-screen keys, your Mac's keyboard, or any MIDI keyboard you connect. • Pitch bend, mod wheel, breath, sustain and aftertouch, with aftertouch set to vibrato, tremolo or swell. • Velocity from a MIDI keyboard, or turn it off and choose how hard every note plays. • An arpeggiator (up, down, up and down, random or as played, over up to three octaves) and a latch that holds each key. • Record what you play and share it as a WAV. • Five tunings: equal, just, and Wendy Carlos's Alpha, Beta and Gamma scales. • Light or dark, as your device is set or as you choose. Drag the keys taller or shorter. • Keys, shortcuts and every synth term, explained under Help. SEE THE SOUND The waveform follows what you play: each operator's envelope, how hard you hit, the pitch, the LFO's wobble, and a chord as one layer per note. Resize it, go full screen, or watch the output itself in the Scope look. PATCH BUILDER: LEARN HOW FM WORKS FM is famous for being hard to program. The Patch Builder shows you why a sound sounds the way it does. • All six operators on a graph, each cable carrying its wave: see a modulator reshape its carrier as you drag. • Draw a cable and the builder snaps to the nearest of the 32 algorithms, so you learn routing by doing it. • Plain words beside the jargon. Edit each operator's ratio, level, envelope and tuning, the LFO and pitch envelope, or use FEEL: thickness, touch and brightness. BLEND Pick two patches and Rithmatic blends them into eight new ones. Play each, and keep the ones you like. YOUR BANK AND FILES • Gather patches from anywhere into your bank, then drag pads to swap or reorder them. • Export the bank as standard DX7 .syx files. Open .syx banks, or a .zip of them, from Files, Mail, AirDrop or the Finder. • Share a sound as a short clip of it playing, with a card and a code that brings the patch into anyone's Rithmatic. WITH A SYNTH, IF YOU HAVE ONE Hardware is optional. Choose your synth in Settings: • Korg Volca FM2 (firmware 1.10 or later, over MIDI): read its current patch, write to any of its 64 memory slots, back up and restore all 16 sequencer patterns, and capture the whole instrument to a snapshot. • DX7 family: send patches and 32-voice banks to a DX7 (mkI/II), TX7, TX802 or the original Volca FM over standard Yamaha voice dumps.
