Patchsynth vs FUJI Drum AUv3

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.

A drum machine cut from light. FUJI renders a shader, gives each of its sixteen pads a different band of the same moving image, and turns what that band sees into a drum. The sky is your hats, the horizon your snare, the ground your kick. Change the picture and the whole kit changes with it. Under the picture is a complete, serious drum machine. EVERY PAD IS A DRUM SYNTH • Three ways to read the image: BODY plays it as a wavetable, SCAN plays the pixels as a waveform, SPECTRAL reads it as a spectrogram • 26 knobs per pad: pitch envelope, sub, snap transient, zero-delay-feedback filter with its own envelope, drive, crush, shape • Per-pad delay and reverb sends, choke groups, and four sidechain buses so the kick can duck the rest • Load your own sample onto any pad and shape it with the same controls THE DICE • Nine genres: 80s Miami, 90s Acid, Boom Bap, Trap, Jungle, Warehouse, Lo-Fi Tape, Industrial, Ambient • A style isn't a preset: it sets the range every value is drawn from, so two rolls of 90s Acid are two different kits that both sound like 90s Acid • It picks the picture, the palette, the tempo and the swing to match • The pattern dice plays the style's signature beat, varied every roll • Freeze any pad and it survives every roll • 91 factory kits to start from, and endless ones from there THE SEQUENCER • 64 patterns of up to 64 steps, each with its own length • Parameter locks, 2/4/8 ratchets, velocity and probability on every step • Record live from the pads, snapped to the grid • Switch patterns mid-play and the change lands on the bar SONG MODE • Paint the arrangement: rows are patterns, columns are slots, and repeating a pattern is painting it wider • 64 slots, played on the bar, in time with your DAW or Ableton Link PLAYED, NOT DIALLED IN • A Kaoss-style XY pad on the whole mix: filter, stutter, crush, gate, delay, space • Draw a path on it and the effect walks it in time with the beat • Fullscreen, with the pattern bank under your other hand • Master rack: tape, flutter, lo-fi, shape, chorus, delay and reverb SHAPE THE SOUND WITH LIGHT • Two shaders, blended: morph the entire kit from one picture into another • 33 color palettes that change the tone, not just the look • A stackable VFX chain that reshapes the pixels every pad reads BUILT FOR YOUR WORKFLOW • AUv3 plug-in AND standalone app, on iPhone, iPad and Mac • Follows your DAW's tempo and transport; pad and master knobs record as automation • Pattern out as MIDI, or export any pattern as a .mid file • MIDI Learn on nearly every control, plus presets for 20 controllers • Ableton Link in the standalone app • Projects save the kit and the pattern bank together, synced over iCloud • Three themes, including SUMI: black ink on washi, every knob drawn by hand • Optional on Mac: let an AI agent drive FUJI over a local connection. Off by default, and nothing leaves your Mac
