Inspired by the PS-1A Phase Shifter (1971). True 6-stage all-pass cascade with Leslie-style speed ramping and three speed presets. Free plugin.
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
Slow (0.5 Hz) for breathing pads, Medium (1.0 Hz) for classic pulse, Fast (6.0 Hz) for vibrato-like warble.
Leslie-Style Speed Ramping
Smooth acceleration and deceleration when switching speeds (τ = 0.5s). Musical transitions, not sudden jumps.
Zero-Latency Processing
Real-time performance with no delay. Perfect for live tracking and monitoring.
Vintage/Modern Modes
Vintage Mode for 100% authentic behavior. Modern Mode adds Depth control and Tempo Sync for DAW integration.
Lowrey-Style Interface
