Efectos de DSP y parámetros
28. Rot.Sp.1 29. Rot.Sp.2
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
Sets the depth of modulation. Higher values produce deeper modulation and therefore a more pronounced
effect.
33. Tremolo1 34. Tremolo2
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
Sets the depth of amplitude modulation. Higher values produce deeper modulation and therefore a more
pronounced tremolo effect.
3. PM DEPTH
Sets the depth of pitch modulation. Higher values produce deeper modulation and therefore a more pro-
nounced vibrato effect.
36. Auto Pan
This is a sophisticated pan program that allows creation of "rotary" pan in addition to straightfor-
ward pan effects.
1. LFO DEPTH
Sets the overall depth of modulation. Higher values produce deeper modulation and therefore a more
pronounced pan sweep.
2. L/R DEPTH
Sets the "depth" of the pan sweep from left to right and right to left.
3. F/R DEPTH
This parameter sets the apparent depth of the sweep from front to rear.
4. PAN DIRECTION
Determines the direction in which the sound sweeps across the stereo sound field.
37. Auto Wah
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
Sets the depth of modulation. Higher values produce deeper modulation and therefore a more pronounced
effect.
30. Rot.Sp.3
Range: 0 ... 127
35. GtrTrem.
