Effects Parameters
4-23
LoAccelCrv
and HiAccelCrv are the shapes of the acceleration curves for the speakers. 0%
is a constant acceleration. Positive values cause the speaker to speed up slowly at first then
quickly reach the fast rate. Negative values cause a quick initial speed-up then slowly settle in
to the fast speed. If set to a low negative value, it will overshoot.
LoSpinDir
and HiSpinDir are the directions of rotation of the speakers. The choice is
clockwise (CW) or counter-clockwise (CCW).
Vibrato/Chorus
The Vibrato/Chorus effect simulates the vibrato and chorus effects on a tone wheel organ,
and is used in conjunction with the Rotary Speaker. It has several unique parameters:
VibChInOut
is an in/out switch for the Vibrato/Chorus effect.
Vib/Chor
is the type of Vibrato/Chorus effect to be used. The choices are from three
vibratos, “V1”, “V2”, “V3”, or three choruses, “C1”, “C2”, “C3.”
Tremolo and AutoPan
Tremolo is amplitude modulation using an LFO. AutoPan moves the signal between the
left and right channels, using an LFO. They have several parameters in common and several
unique ones.
LFO Rate
is the rate of the LFO. The range is 0 to 10.00 Hz, or 0 to 12.00 x the tempo.
Rate Scale
multiplies the speed of the LFO rate into the audio range. The range is 1 to
25088 x. When above 16x, the values increment in semitone steps. When the LFO Rate is
set to 1.00 Hz, the value of this parameter is equal to the LFO frequency in Hertz.
LFO Shape
is the waveform type for the LFO. Choices are Sine, Saw+, Saw-, Pulse, and Tri.
LFO PlsWid
or Pulse Width. When the LFO Shape is set to Pulse, this sets the pulse width
as a percentage of the waveform period. When the width is set to 50%, the result is a square
wave. This parameter has no effect if other waveform types are chosen. Range is 0 to 100%.
AutoPan
Origin determines the axis for the panning motion. At 0%, the panning is centered between
the speakers. Positive values shift the axis to the right, while negative values shift it to the left.
At -100% or +100% (the range limits), there is no panning action.
ImageWidth
is the width of the original input program material before it is auto-panned.
At 0% (minimum), the input image is shrunk to a single point source, allowing maximum
panning excursion. At 100% (maximum), the original width is maintained so no panning
can occur.
Pan Width
controls the amount of pan excursion. It is the percentage of total panning
motion available after Origin and ImageWidth are set. Range is 0 to 100%.
