Patchsynth vs QuickTrack

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.

QuickTrack is a multitrack music studio for iPhone, iPad, and Mac. Record ideas, shape songs, mix with native DSP, and deliver independently verified audio while your Original media stays protected. RECORD AND ARRANGE: - Record vocals and instruments with metronome, count-in, cycle recording, route status, and latency compensation - Build audio, MIDI, and drum-pattern tracks with sections, markers, snap, zoom, and project-local Undo and Redo - Split, move, trim, fade, reverse, stretch, and pitch audio non-destructively - Keep autosave, crash recovery, unfinished takes, and explicit relink states understandable MIDI AND INSTRUMENTS: - Edit notes and velocity in the Piano Roll, program beats in the Step Sequencer, and draw clip or track automation - Play responsive software keys and drum pads, then record the performance directly into the project - Use built-in instruments or import your own SF2, SFZ, DrumKit JSON, and WAV sample content - Capture supported system or USB MIDI with sustain, aftertouch, and controller data MIX AND MASTER: - Control faders, pan, mute, solo, inserts, Reverb and Delay sends, buses, meters, and a true-peak master limiter - Automate volume, pan, sends, and effect parameters with sample-accurate live and offline rendering - Measure loudness and true peak, compare A/B previews, and review explainable Mix or Mastering Assist changes before Apply SONGWRITING ASSISTS: - Turn monophonic humming into editable MIDI and create local Song Starter, Chord Progression, and Rhythm proposals - Draft lyrics through an optional configured provider without giving it direct project-write access - Preview, partially apply, discard, undo, or redo every proposal through the Review Inbox - Import aligned stems from existing files and preserve clear Derived lineage EXPORT AND PROJECT PORTABILITY: - Export verified master WAV, MP3, or M4A, aligned track and bus stems, MIDI, and seamless BGM loops - Save compact projects or portable .qtrack archives with embedded media and independently checked manifests - Work with device files and explicitly connected folders while scoped permissions and revocation remain visible - Keep Original, Project, Derived, and Export media separate with stable identity and lineage ACCESSIBLE, RESPONSIVE WORKFLOW: - Move between Library, Arrange, Edit, Mix, and AI surfaces on phone, tablet, or desktop - Use clear empty, progress, cancel, retry, unavailable, permission, and recovery states - Navigate with touch, keyboard shortcuts, screen readers, large text, light or dark appearance, and reduced motion QuickTrack Pro: - Removes the mobile Library banner after the 7-day trial - Hides desktop reminders - Supports continued QuickTrack development - Recording, editing, instruments, effects, assists, and export remain available without Pro Terms of Use: https://kakitiro.com/quickapps/quicktrack/terms/
