Patchsynth vs TONAUT

Patchsynth is a Eurorack-style modular synthesizer for iPhone and iPad — and a place to actually learn how modular synthesis works, one patch cable at a time. Instead of a fixed synth engine with knobs, you build your own instrument by dragging cables between modules: oscillators into filters, envelopes into amplifiers, LFOs wobbling anything you point them at. If you've ever wanted to understand what a Eurorack rig actually does, this is the fastest way in. LEARN BY PATCHING, NOT BY READING 28 hands-on Lessons cover every module, from your first oscillator to full generative patches — some just explain, others build a real patch step-by-step in front of you as you tap "Next." No prior synthesis knowledge required. TRAIN YOUR EAR 15 Challenges hide a patch and play it for you — your job is to rebuild it by ear, with hints if you get stuck. A genuinely fun way to internalize how filters, envelopes, and modulation actually sound. 21 REAL MODULES Oscillator · Filter · VCA · ADSR Envelope · LFO · Noise · Delay · Reverb · Mixer · Sequencer · Arpeggiator · Clock · Attenuverter · Quantizer · Slew Limiter · Sample & Hold · Logic · Ring Modulator · Sampler · Keyboard · Output (with a live oscilloscope) Record your own sounds with the Sampler, or use the built-in factory drum kit. Quantize any CV to a musical scale. Chain multiple clocks for polyrhythms. It's a real modular rig, just without the cables costing $30 each. 70+ FACTORY PATCHES From simple bass and pad sounds to sprawling, 20+ module "flagship" patches — browse them, load them, take them apart to see how they're wired, then make them your own. PLAY IT WITH REAL GEAR Full MIDI support over Bluetooth or USB — plug in any MIDI keyboard or controller and play your patch's Keyboard module directly, no setup beyond pairing. BUILT FOR TOUCH, NOT PORTED FROM DESKTOP Every interaction — dragging cables, turning knobs, panning and zooming a big patch — is designed for a phone screen from the ground up. A dedicated Patch Bay view even gives you a spreadsheet-style matrix of every connection when patches get complex. Undo and redo everything. Save as many patches as you like. No ads, no in-app purchases, no internet connection required — just synthesis.

Tonaut is a synthesizer, drum machine, sequencer and eight-track tape recorder in one instrument, made to be played rather than programmed. Pick a sound, tap out a pattern and record it to tape, all on one panel that feels more like hardware than an app. IPHONE DUO • Folded, one octave on the outer screen. Half folded, the screens above the keys. Open, the whole instrument. Folding never stops the music SOUNDS • Nine synth engines: virtual analog, six-operator FM, wavetable, pulse, modeled string, a seven-oscillator swarm, grains, a classic analog poly and a sampler • Every engine has a 3D screen that moves with your playing, or a classic view • Over 500 sounds, from warm pads to glassy bells and growling bass, including 147 sampled instruments • Edit every sound in depth, save your own, and star your favorites • Load DX7-style SysEx banks into the FM engine • Four effects on every sound from sixteen types, from tape echo and huge reverb to distortion, pump, phaser and lo-fi • A master effect, a master EQ and an EQ on every lane DRUMS • 43 kits on three drum engines: kits made from real recorded drums, synthesized kits where every pad is its own drum, and slice kits • Knock and Cinder kits drawn in 3D, moving with every hit • A groove player: hold any pad and the whole kit plays one of sixteen grooves • Make kits from your own recordings or from audio files, one per pad KEYS AND CHORDS • Pick a key and scale and its keys light up; LOCK keeps every note in key, per lane • CHORDS plays a whole chord from one key, and works with the arpeggiator and the sequencer • Chord pad: seven chords from your key and a stick that turns each into a 7th, 9th, sus, dim and more, with strum and bass, also from a MIDI keyboard SEQUENCER • Eight lanes, each with its own sound and sixteen patterns of up to 64 steps • Write step by step or record live, with chords, slides, ratchets and chance • STEP REC: each note or chord you play fills a step, with rest and tie, also from MIDI • Pattern Play: queue the next pattern and every lane moves on together • Copy, swap and transpose patterns, and reorder lanes • An arpeggiator on every synth lane PLAY IT LIVE • A Perform page with TONE and SPACE for every lane, which glide back when you stop • An X/Y pad that bends pitch and moves the sound under one finger • One-tap mutes, tap tempo, click and count-in TAPE • Eight tracks of 20 minutes each, or six tracks of 30 minutes, chosen per project • Record every lane to its own track, or several onto one • Loop, reverse, stutter, brake and catch the last 30 seconds you played • A tape mixer, and pinch to zoom from a few bars to the whole song SAMPLING • Sample with the microphone, a USB interface, or Tonaut itself • Link your sample folders once, tap a file to hear it, and load it onto a pad or into the sampler • Drag audio files in from other apps onto a drum pad or the sampler MIDI • Play Tonaut from USB or Bluetooth MIDI keyboards and controllers, on the selected lane or with each lane on its own channel • Send any lane to your own synths and drum machines, with clock and start/stop SHARE AND EXPORT • Share a loop from the tape as a vertical video or as audio, ready to post • Send a whole song, samples and all, as one file a friend opens in Tonaut • Export a stereo mix, separate stems as WAV files, or MIDI files of every lane • Optional iCloud sync between your iPhone and iPad One purchase covers iPhone, iPad and iPhone Duo, each with its own layout, in six looks: Light, Dark, TN-1, TN-1 Dark, TN-XY and TN-SIGNAL. No subscription, no account, and Tonaut collects no data. Your music stays yours. REQUIREMENTS • An iPhone with an edge-to-edge screen: iPhone XS, XR or newer, iOS 17 or later.
