## What is LogSynth?

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.
