Rotor Cabinet Effect

The Rotor Cabinet effect emulates the rotating loudspeaker cabinet of a Hammond organ’s Leslie effect. It simulates both the rotating speaker cabinet, with and without deflectors, and the microphones that pick up the sound.

Basic Rotor Speaker Parameters

The Rotor Cabinet offers the following basic rotor speaker parameters:

Figure. Basic Rotor Speaker parameters.
  • Rotor Speed buttons: These switch the rotor speed in the following ways:
    • Chorale: Slow movement.
    • Tremolo: Fast movement.
    • Brake: Stops the rotor.

Advanced Rotor Speaker Parameters

The Rotor Cabinet offers the following advanced rotor speaker parameters:

Figure. Advanced Rotor Speaker parameters.
  • Rotor Fast Rate slider: Adjust to set the maximum possible rotor speed (Tremolo). The Tremolo rotation speed is displayed in Hertz.
  • Acc/Dec Scale slider: The Leslie motors need to physically accelerate and decelerate the speaker horns in the cabinets, and their power to do so is limited. Use the Acc/Dec Scale parameter to determine the time it takes to get the rotors up to a determined speed, and the length of time it takes for them to slow down.
    • Set the slider to the far left to switch to the preset speed immediately.

    • As you drag the slider to the right, it takes more time to hear the speed changes.

    • At the default position (1) the behavior is Leslie-like.

Rotor Cabinet Microphone Parameters

The Rotor Cabinet offers the following microphone parameters:

Figure. Microphone parameters.
  • Mic Distance slider: Determines the distance of the virtual microphones (the listening position) from the emulated speaker cabinet. Use higher values to make the sound darker and less defined. This is typical of microphones when positioned further from the sound source.
  • Mic Angle slider: Use to define the stereo image, by changing the angle of the simulated microphones.
    • An angle of 0° results in a mono sound.

    • An angle of 180° causes phase cancellations.
