Where to get itAvailable from Reason Studiosreasonstudios.com

Polar is a dual pitch shifter Rack Extension for Reason Studios designed to add real-time pitch manipulation, modulation capabilities, and filter processing to audio. Drawing inspiration from classic '80s harmonizing effect units but with modern enhancements, Polar excels at everything from micro-pitch thickening to dramatic special effects, with dedicated controls for creating everything from subtle widening to twisted, modulated pitch shifts.

Key Features

01Dual independent pitch shifters with Shift and Fine controls (±2 octaves, ±0.5 semitones)
02Four pitch algorithms: Smooth, Classic, Loop, and Reverse Loop with variable analysis speeds (Slow/Medium/Fast)
03Stereo delay buffer (400ms default, expandable to 1600ms with 4X button) with feedback controls for repeating pitch effects
04Multi-mode filter section with Lowpass, Bandpass, Highpass, and Comb filters (12dB/Octave)
05LFO and Envelope modulation for pitch, filter, delay, and auto-pan parameters
06MIDI keyboard control and CV modulation inputs for comprehensive real-time control

Things to Try

  • 01Select Classic algorithm for rougher '80s-style harmonizing sounds, or Smooth for high-quality polyphonic material
  • 02Choose Fast mode for vocals with lowest latency (~24ms), Medium mode (~48ms) for drums and bass, or Slow mode (~96ms) for complex polyphonic audio
  • 03Turn up Feedback knobs with Delay enabled to create continuously decreasing pitches on pitched-down audio or continuously increasing pitches on pitched-up audio
  • 04Pan Pitch Shifter 1 and 2 hard left and right with slight Fine detuning, then turn up the Pitch Shifter 2 Delay knob for a wide pseudo-stereo effect
