What Makes It Special
6-Stage All-Pass Cascade
Creates 3 sweeping notches for rich, complex phasing. First-order all-pass filters with correct phase response.
Three Speed Presets + Continuous Rate
Authentic 0.5 / 1 / 6 Hz rockers, plus a continuous Rate knob (0.05–12 Hz) in Modern Free for any rate in between.
Tempo Sync — 15 Divisions
Lock the LFO to host BPM across 15 musical divisions from 1/32 to 4/1, including triplets and dotted figures.
Stereo Spread
Independent L/R LFO phase offset for a wide modern image. Mono-compatible at zero, 180° at maximum.
Leslie-Style Speed Ramping
Smooth acceleration and deceleration when switching speeds (τ = 0.5s). Musical transitions, not sudden jumps.
30 Factory Presets + A/B Compare
Seven categories (Init, Subtle, Classic, Modern, Synced, Vintage, Creative) plus user save / delete; A/B compare in the header.
Nivipedia — In-Plugin Encyclopedia

Vintage/Modern Modes
Vintage is bit-identical to the original PS-1A. Modern adds Depth, Sync, Rate, Spread and parameter smoothing — Vintage signal path is never touched.
Premium Cream-Chassis UI
Period-accurate Lowrey-style speed rockers, hover tooltips with live value tracking, double-click value entry, FSH-1-style illuminated power.
