These effects simulate the swirling sound of the rotary speakers often used with electronic organs.
1. LFO FREQUENCY Range: 0 … 127
Sets the speed of LFO (Low Frequency Oscillator) modulation, and therefore the rate of effect variation.
2. LFO DEPTH
Range: 0 … 127
Sets the depth of modulation. Higher values produce deeper modulation and therefore a more pronounced
effect.
Although “tremolo” effects, these effects also include a pitch-modulation depth parameter that can be
used to add a touch of vibrato.
1. LFO FREQUENCY Range: 0 … 127
Sets the speed of LFO (Low Frequency Oscillator) modulation, and therefore the rate of effect variation.
2. AM DEPTH
Range: 0 … 127
Sets the depth of amplitude modulation. Higher values produce deeper modulation and therefore a more
pronounced tremolo effect.
3. PM DEPTH
Range: 0 … 127
Sets the depth of pitch modulation. Higher values produce deeper modulation and therefore a more pro-
nounced vibrato effect.
This is a sophisticated pan program that allows creation of “rotary” pan in addition to straightfor-
ward pan effects.
1. LFO DEPTH
Range: 0 … 127
Sets the overall depth of modulation. Higher values produce deeper modulation and therefore a more
pronounced pan sweep.
2. L/R DEPTH
Range: 0 … 127
Sets the “depth” of the pan sweep from left to right and right to left.
3. F/R DEPTH
Range: 0 … 127
This parameter sets the apparent depth of the sweep from front to rear.
4. PAN DIRECTION
Range: L
<>
R, L
>
R, L
<
R, Lturn, Rturn, L/R
Determines the direction in which the sound sweeps across the stereo sound field.
A fully automatic wah effect that can be set to produce a wide range of sounds.
1. LFO FREQUENCY Range: 0 … 127
Sets the speed of LFO (Low Frequency Oscillator) modulation, and therefore the rate of effect variation.
2. LFO DEPTH
Range: 0 … 127
Sets the depth of modulation. Higher values produce deeper modulation and therefore a more pronounced
effect.
