x42 Whirl (Simple)

x42-whirl (Simple) recreates the sound and properties of the electromechanical rotating speaker device that brought world-wide fame to the name and products of Don Leslie.

x42-whirl calculates six reflections depending on the angles of the horn and drum as well as distance and position of the microphones to emulate the reverberant scattering corresponding to the dimensions and scattering characteristics of the cabinet. Furthermore the model accounts for artifacts such as signal leakage from the tweeter which does not pass through the horn. The motor-control allows to set two target speeds (slow/chorale and fast/tremolo) for each of the horn and drum rotors in RPM as well as acceleration and deceleration time-constants in seconds (to reach half the speed).

The Whirl is a great mono-to-stereo effect which can add stereo spaciousness to keys, guitars, or even vocals.
p(banner tip). When inserted on a mono channel, whirl will automatically convert your mono track into a stereo output – no manual “pin connections” needed.

Whirl (Simple) does not provide a custom GUI. Instead it uses the generic control-panel with these controls:

• Enable: this switches the effect on&off, click-free
• Motors Ac/Dc: select the speed of the rotor horn and drum
• Horn Level: level adjustment for the horn (highs), in dB
• Drum Level: adjust the Drum level in dB
• Drum Stereo Width: move the slider left (lower) for a more mono sound. Move it right for a wider stereo sound. 1.0 is the default stereo setting
