LogSynth

A polyphonic virtual-analog synth with a physically modeled diode drive filter, 41 hand-tuned presets, and a full AUv3 plugin for the host of your choice.

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. Hard sync, FM, and a zero-delay-feedback state-variable filter — switchable low/high/bandpass, 12 or 24 dB/octave — give you real analog-style shaping. The filter's drive stage 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.
