SynthStation transforms your iPhone, iPod touch or iPad into a portable music production studio for mobile music creation. SynthStation gives you three powerful synthesizers for creating and modifying sonic textures used for melodies, chords, and bass lines. Built around Akai Professional’s history in synthesis and drawing on the newest MINIAK synth, SynthStation sounds great and offers wide-ranging sonic flexibility with its virtual analog synthesis. From the moment you start SynthStation, you'll know your way around. It is jam-packed with tools to help you create music with the convenience of your touch screen and each section works the way you work. With SynthStation, you can create and save sequences and complete songs. The app contains three different three-oscillator synths and a range of drum kits you can sequence and mix right in the SynthStation. For creating melodic and accompaniment parts, the SynthStation contains an arpeggiator with preset patterns, built-in effects and filters, and an XY touch control interface for expressive control of key parameters. PERFORM Play with keys, XY and arpeggiator controls. This is perfect place to make magic happen because it gives you access to all the common controls you’ll need in a performance or creation setting. SYNTH Complete synthesis controls from oscillators to LFOs, envelopes, and more. You can control a wide range of filters to dial in exactly the sound you need. Choose from Sine, Triangle, Square or Sawtooth on your VCO and start creating your own signature sounds from scratch. Filter Cutoff and Resonance are just two taps away. DRUMS In addition to SynthStation's three synthesizers, we've included drum kits and a visual representation of the most iconic beat making tool in the world - MPC pads. Just pick your kit and start tapping beats anywhere, anytime. Includes: Drum Kit – select the drum kit and play it with onscreen pads. Drum Edit – tune, mix, and customize your drums. SEQUENCER Keyboard grid – see your keyboard sequencing and edit notes easily. Drum grid – build and modify drum tracks with a visible sequencer grid. SONG/SEQUENCE Select and save your Song/Sequence projects. You can recall your Songs and work on them later, and even export them for further editing in your desktop audio applications. CONTROL XY – two axes of control for hands-on, real-time control. Just like a joystick, the XY controller can snap back to the zero point. Tempo – control tempo and even tap in the tempo you want. MIXER The Mixer in SynthStation includes touch-controlled faders for each of the three synthesizers and the drum section as well as FX send for each. Mixer – mix all the levels of the parts and effects. Just like a hardware mixer, there are faders, mutes, and effect routing. Effects – select and control FX type and parameters. SynthStation Studio enables you to create and produce music anywhere on your iPhone, iPod touch or iPad.

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.

Verdict
The clearest difference is price: Rithmatic at Free against SynthStation's $1.99. Rithmatic also leads on rating (4.0 vs 2.3) and update cadence (every 2 days vs every 3 months). SynthStation's advantage is ratings volume (178 vs 4) and iOS requirement (4.3 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
