LP n Freq are shelving frequencies for one-pole lowpass lters on each of the distortion
stages. LP0 Freq handles the initial low pass prior to the rst distortion stage. e other low
pass controls follow their respective distortion stages. Range is 16 to 25088 Hz.
Rotating Speakers
An eect that includes Rotating Speakers breaks the signal into two frequency bands,
“rotates” each band separately through a virtual speaker, and then combines the outputs with
a pair of virtual “microphones” whose angle relative to the speakers is adjustable. A number
of very sophisticated parameters have been included in the Rotating Speakers eect, to give
the eect a great degree of realism. Because of the complexity of the eects, you might want
to approach any parameters that seem a little obscure to you with caution.
Roto InOut engages or bypasses the rotary speaker eect.
ere are four virtual microphones, with two each on the woofer (LoMic A and LoMic B)
and on the tweeter (HiMic A and HiMic B). Each microphone has:
Pos (position), the angle of the microphone from the front of the virtual speaker, from -180
to 180degrees;
Lvl (level) from 0 to 100%; and Pan, the left/right panning of the microphone’s output,
from -100% (full left) to 100% (full right). Other parameters:
Lo Beam W and Hi Beam W set the acoustic radiation patterns (“beam width”) of the two
drivers in the rotating speaker. If you imagine looking down on the rotating speaker, this is
the angle between the -6 dB levels of the beam. e range is from 45° to 360°. At 360°, the
driver is omnidirectional.
Xover (Crossover) is the frequency at which high and low frequency bands are split and sent
to separate rotating drivers. e range is 16 to 25088 Hz.
Lo Gain and Hi Gain are the gains of the signal passing through the rotating woofer or
tweeter, respectively. e range is O/-79.0 to 24.0 dB.
Lo Size and Hi Size are the eective sizes (radius of rotation) of the rotating speakers in
millimeters. is aects the amount of Doppler shift or vibrato of the low frequency signal.
e range is 0 to 250 mm.
Lo Trem and Hi Trem control the depth of tremolo (amplitude modulation) of the signals. It
is expressed as a percentage of full scale tremolo. e range is 0 to 100%.
LoResonate and HiResonate are simulations of cabinet resonant modes expressed as a
percentage. For realism, you should use very low settings. e range is 0 to 100%.
Lo Res Dly and Hi Res Dly are the number of samples of delay in each resonator circuit in
addition to the rotation excursion delay. e range is 10 to 2550 samples.
LoResXcurs and HiResXcurs are the number of samples of delay to sweep through the
resonator at the rotation rate of each rotating speaker. e range is 0 to 510 samples.
