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.

Move the sound. SWAY is a synthesized rhythm instrument for iPhone and iPad. Build patterns, shape sounds, and perform with touch and motion. • 16 synthesized tracks and four patterns. • Independent track lengths from 1 to 16 steps for shifting rhythms. • Per-step parameter locks, live recording, and swipe-to-paint sequencing. • Live pads, track mutes and solo. • Eight momentary punch-in effects: Repeat, Filter, Brake, Echo, Reverse, Crush, Gate and Pitch. Stack effects with multi-touch and release each pad to restore the sound. • Hold TRIG / YES for temporary rhythmic fills, with slide-controlled density. • Three independent LFOs per track with synthesis and effect destinations. • Independent track effects and a shared effects bus: delay, reverb, DJ filter and tape loops. • Vinyl texture with warmth, drift and dust. • MIDI input and output, including Bluetooth MIDI connections to compatible hardware and virtual MIDI routing to other music apps. • Per-track MIDI channels, notes and gate lengths, with per-step Note and Gate locks. Choose internal sound, MIDI output, or both for each track. • Keep performing across apps with background playback when MIDI is enabled. • Bind a display parameter to device motion, then rotate your device to play it. • Export stereo WAV or MP3, or aligned WAV stems for your DAW. • Save and delete projects locally, and import or export editable project files. • A portrait instrument on iPhone and a wide landscape console on iPad. Sound generation and project storage work locally. Bluetooth MIDI requires a compatible device or adapter.
