Rithmatic vs Aural Studio

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. FREE AND PRIVATE Every feature is free; tips are optional and unlock nothing. Rithmatic works offline and collects no personal data: no account, no analytics, no ads. KORG and volca are trademarks of Korg Inc. DX7 and TX are trademarks of Yamaha Corporation. Rithmatic is an independent app and is not affiliated with or endorsed by either.

Press play. Then make the sound your own. Aural Studio starts you inside a complete soundscape, not at an empty editor. Open one of four presets and listen. When a layer catches your ear, open the soundscape, reshape it, and save your version to keep exploring. MEET RESONANT TIDE A deep brown-noise bed rolls beneath two pink-noise breakers. White-noise foam brightens the surface, with a subtle binaural current underneath. Hear the whole five-layer soundscape first; then open it up. FOLLOW WHAT CATCHES YOUR EAR Mute Rolling Waves and notice what drops away. Reorder the stack or duplicate a layer before an experiment. Add sine, triangle, square, and sawtooth tones, plus white, pink, and brown noise. The controls change with the kind of layer you choose. SEND A WAVE ACROSS STEREO Give Rolling Waves a repeating path between left and right. Compatible tone and noise layers can hold a stereo position or move along a repeating path. Stereo headphones are recommended for the intended separation. DRAW HOW THE SOUND UNFOLDS Choose a value available for the layer and draw a curve across its duration. Scrub to a moment, then listen as playback follows the same rise, dip, or turn. DARKEN OR BRIGHTEN THE TEXTURE For tones and noise with filtering, choose low-pass or high-pass and adjust cutoff and resonance while you listen. LET ONE WAVE SHAPE TWO MORE When Rolling Waves swells, Sea Foam rises and the Binaural Current's beat shifts with it. In Resonant Tide, the changing volume of one layer can drive those two values. Shape one source instead of redrawing the same movement. Your original settings remain ready if you change course. KEEP YOUR VERSION Save and reopen the soundscape. Duplicate it before a new direction. Import or export editable Aural documents. Your documents stay on your device unless you explicitly export them. Aural Studio is free on the App Store. No account. No subscription. Built for iPhone; requires iOS 26 or later. Aural uses limited TelemetryDeck product analytics. See the Privacy Policy for the current data disclosure. No ads or cross-app tracking. Stereo headphones are recommended for binaural and stereo-motion playback. Listen at a comfortable level, stop if you feel discomfort, and do not listen where reduced attention could create risk.
