Algorithm Reference-109
DistWarmth
A lowpass Þlter in the distortion control path. This Þlter may be used to reduce some of
the harshness of some distortion settings without reducing the bandwidth of the signal.
[Rotor 4 only]
Cabinet LP
A lowpass Þlter to simulate the band-limiting of a speaker cabinet. The Þlter 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.
Lo Beam W
The rotating speaker effect attempts to model a rotating woofer for the low frequency
driver. The acoustic radiation pattern of a woofer tends to range from omnidirectional
(radiates in directions in equal amounts) to a wide beam. You may adjust the beam
width from 45
°
to 360
°
. If you imagine looking down on the rotating speaker, the beam
angle is the angle between the -6 dB levels of the beam. At 360
°
, the woofer is
omnidirectional.
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.
Hi Beam W
The rotating speaker effect attempts to model a rotating horn for the high frequency
driver. The acoustic radiation pattern of a horn tends to be a narrow beam. You may
adjust the beam width from 45
°
to 360
°
. If you imagine looking down on the rotating
speaker, the beam angle is the angle between the -6 dB levels of the beam. At 360
°
, the
horn is omnidirectional (radiates in all directions equally).
Mic Pos
The angle of the virtual microphones in degrees from the ÒfrontÓ of the rotating speaker.
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). There are
four of these parameters to include 2 pairs (A and B) for high and low frequency drivers.
Mic Lvl
The level of the virtual microphone signal being sent to the output. There are four of
these parameters to include 2 pairs (A and B) for high and low frequency drivers.
Mic Pan
Left-right panning of the virtual microphone signals. A setting of -100% is panned fully
left, and 100% is panned fully right. There are four of these parameters to include two
pairs (A and B) for high and low frequency drivers.
