MODULATION EFFECTS: SCANNER VIBRATO

The Scanner Vibrato effect in Logic Pro emulates the lush, swirling modulation circuit found in the classic Hammond B3 organ and its rotary speaker system. Unlike a typical chorus or flanger, Scanner Vibrato modulates pitch and phase to create a warm, organic motion that’s especially expressive on organs, electric pianos, and synth pads. Its distinct depth and vibrato modes produce everything from subtle shimmer to dramatic, rotary-like movement — perfect for vintage textures or soulful modern tones.

Key Features

• Type Selector (V1, V2, V3, C1, C2, C3): Choose between Vibrato (V modes) and Chorus (C modes) variations.

  1. V1–V3 provide increasing amounts of pitch modulation for traditional vibrato effects.

  2. C1–C3 add a delayed, modulated signal for a richer, chorus-like texture.

• Depth: Controls how much the pitch is modulated. Higher values create a more pronounced wobble, while lower settings add subtle movement and warmth.

• Stereo Phase: Adjusts the phase relationship between the left and right channels. Increasing this value widens the stereo image and enhances the spatial swirl associated with classic Hammond-style modulation.

• Left / Right: Fine-tune the modulation rate independently for each stereo channel to create asymmetrical or evolving motion. Matching both controls locks the modulation speed for a centered, unified effect.

Best Use Cases

• You want to recreate classic Hammond organ modulation with warmth and authenticity.

• You’re adding vintage character to electric pianos, pads, or synths.

• You’d like to introduce movement and width to sustained sounds without the shimmer of chorus or phasing.

• You’re looking to animate static parts like organ chords, clean guitars, or synth leads.

Popular Song Examples

• Procol Harum – “A Whiter Shade of Pale”

• Booker T. & the M.G.’s – “Green Onions”

• Pink Floyd – “Time” 

• Steely Dan – “Do It Again”

Workflow Tips

• Start with V1 or C1 for subtle movement; increase to V3 or C3 for lush motion.

• Try Depth around 30–40% for realistic modulation without detuning the signal too far.

• Widen with Stereo Phase: Small offsets (10–30°) add stereo width; larger values (60°+) create more dramatic swirl.

• Blend with Electric Pianos and Organs: The Scanner Vibrato pairs beautifully with Logic’s Vintage B3 and Vintage Electric Piano instruments.

• Experiment with Automation: Automate Depth or Type switches (V → C) during sections for evolving tone color.
