Where to get itIncluded with Studio Onepresonus.com

Rotor is a rotary speaker effect that simulates a tube-powered amplifier with independently rotating high-mid horn and bass woofer, recreating the sound of classic electric organ amplifiers. It excels at adding motion and tonal character to organs, guitars, and other instruments through realistic braking and acceleration effects. Two amplifier models are recreated using State Space Modeling technology.

02Independent horn and woofer speed controls
03Two amplifier models (A/B toggle)
04Horn Q resonance blending
05Microphone distance positioning
06Woofer/horn balance control
07Stereo spread width adjustment

Things to Try

  • 01Lower Drive settings produce cleaner tones, higher settings increase overdrive character
  • 02Position the virtual microphone close to the speaker (low Distance) for pronounced stereo sweeping, or further away (high Distance) for subtler diffuse effects
  • 03Set Woofer Speed and Horn Speed to identical values for coordinated rotation, or differing values for contrasting rotations
