Patchsynth
Read full descriptionHide full description
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.

Verdict
The clearest difference is price: CC Metronome at Free against Patchsynth's $7.99. CC Metronome also leads on iOS requirement (12.0 vs 17.0). Patchsynth's advantage is in-app purchases (none vs 2). On ads and device support there is nothing between them.
