LogSynth
Read full descriptionHide 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 โ 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 โ no watered-down mobile version, no feature gating between standalone and plugin modes.
