Cabinet HP A highpass fi lter to simulate the band-limiting of a speaker cabinet. The fi lter controls the
lower frequency limit of the output.
Cabinet LP A lowpass fi lter to simulate the band-limiting of a speaker cabinet. The fi lter controls the
upper frequency limit of the output.
Xover The frequency at which high and low frequency bands are split and sent to separate
rotating drivers.
Lo Gain The gain or amplitude of the signal passing through the rotating woofer (low frequency
driver.
Lo Rate The rotation rate of the rotating woofer (low frequency driver). The woofer can rotate
clockwise or counter-clockwise. The direction of rotation depends on the sign of the rate
parameter. Assuming microphone angles are set toward the front (between -90° and 90°)
and microphones at positive angles are panned to the right (positive pan values), then
positive rates correspond to clockwise rotation when viewed from the top.
Lo Size The effective size (radius of rotation) of the rotating woofer in millimeters. Affects the
amount of Doppler shift or vibrato of the low frequency signal.
Lo Trem Controls the depth of tremolo of the low frequency signal. Expressed as a percentage of
full scale tremolo.
Hi Gain The gain or amplitude of the signal passing through the rotating tweeter (high frequency
driver.
Hi Rate The rotation rate of the rotating tweeter (high frequency driver). The tweeter can rotate
clockwise or counter-clockwise. The direction of rotation depends on the sign of the rate
parameter. Assuming microphone angles are set toward the front (between -90° and 90°)
and microphones at positive angles are panned to the right (positive pan values), then
positive rates correspond to clockwise rotation when viewed from the top.
Hi Size The effective size (radius of rotation) of the rotating tweeter in millimeters. Affects the
amount of Doppler shift or vibrato of the high frequency signal.
Hi Trem Controls the depth of tremolo of the high frequency signal. Expressed as a percentage of
full scale tremolo.
Mic Angle The angle of the virtual microphones in degrees from the “front” of the rotating speaker.
For the left microphone the angle increases clockwise (when viewed from the top), while
for the right microphone the angle increases counter-clockwise. This parameter is not well
suited to modulation because adjustments to it will result in large sample skips (audible
as clicks when signal is passing through the effect).
LoResonate A simulation of cabinet resonant modes express as a percentage. For realism, you should
use very low settings. This is for the low frequency signal path.
Lo Res Dly The number of samples of delay in the resonator circuit in addition to the rotation
excursion delay. This is for the low frequency signal path.
LoResXcurs The number of samples of delay to sweep through the resonator at the rotation rate of the
rotating speaker. This is for the low frequency signal path.
HiResonate A simulation of cabinet resonant modes express as a percentage. For realism, you should
use very low settings. This is for the high frequency signal path.
Hi Res Dly The number of samples of delay in the resonator circuit in addition to the rotation
excursion delay. This is for the high frequency signal path.
