About

Patchsynth

Features
Read 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.

About

LogSynth

Features
Read full description

LogSynth is a polyphonic virtual-analog synthesizer built for people who care what's actually happening in the signal path, not just what the preset browser looks like. Every voice runs five anti-aliased oscillators (sine, triangle, saw, pulse with PWM, and a band-limited impulse train) plus a dedicated sub-oscillator and noise source, mixed per-voice with independent amp envelopes. Chunky oscillators, crisp effects and a zero-delay-feedback state-variable filter — switchable low/high/bandpass. The drive effect is powered by a physically modeled diode circuit, numerically integrated rather than a lookup-table approximation, so pushing it into saturation behaves the way an actual analog drive would. FEATURES - 8-voice polyphony, 5 oscillators + sub + noise per voice - Zero-delay-feedback state-variable filter with resonant feedback and diode drive saturation - 5 independent oscillator envelopes plus a dedicated filter envelope - 2 assignable LFOs and an 8-slot modulation matrix - Built-in chorus, delay, FDN reverb, and 4-mode distortion - 41 factory presets across Bass, Lead, Pluck, and Effects - One-tap patch randomizer with adjustable intensity - Real-time oscilloscope, on-screen keyboard, and CoreMIDI input - Runs standalone or as an AUv3 instrument inside AU hosts Whether you're sound designing from scratch or dropping it into a DAW as a plugin, Logsynth gives you the same engine everywhere — no watered-down mobile version, no feature gating between standalone and plugin modes.
