About

PatchLens

Features
Read full description

Save synth and pedal settings from a photo, then add editable hotspots and recall notes. The demo and 3 patch records stay free; Pro Lifetime is a one-time unlock. PatchLens helps musicians capture hardware synth, pedal, and semi-modular settings as private local patch records. Take or import a photo, mark the knobs and jacks that matter, add values and notes, then search your local patch library later. Optional on-device text recognition can suggest visible panel labels, but you stay in control of every saved value. PatchLens does not require an account, does not upload your photos, and does not promise automatic universal knob or cable detection. Pro Lifetime is a one-time in-app purchase that unlocks the full local patch library, on-device OCR label assist, and recall-sheet sharing. The bundled demo and 3 patch records stay free.

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 β€” 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 β€” no watered-down mobile version, no feature gating between standalone and plugin modes.
