Effects Parameters
8-20
Retrigger is the input-signal threshold at which the envelope detector resets, so that it can
trigger again. This parameter is only useful when it is set below the value of Trigger. Range is
from -79 to 0 dB.
Env Rate
is the envelope detector decay rate. This can be used to prevent false triggering.
When the signal envelope falls below the retrigger level, the filter can be triggered again
when the signal rises above the trigger level. Since the input signal can fluctuate rapidly, it
is necessary to adjust the rate at which the signal envelope can fall to the retrigger level. The
range is 0 to 300.0 dB/sec.
Rel Rate
is the downward slew (release) rate of the triggered envelope generator. The range is
0 to 300.0 dB/sec.
Smth Rate
slows down the envelope follower. If set lower than the release rate, it will
dominate it. You can also use the smoothing rate to lengthen the attack of the internal
envelope. The range is 0 to 300.0 dB/sec.
LFO Filter
The LFO filter is continuously swept between two resonant frequencies over a period of time.
The LFO frequency, expressed in BPM and beats, can be fixed or set to follow System tempo.
Min Freq
and Max Freq are the low and high limits of the resonant frequency as the filter is
swept. You can set the Min Freq higher than the Max Freq, in which case the filter will sweep
“upside down” relative to the controlling clock. The range for both is 16 to 8372 Hz.
LFO Shape
is the waveform type for the LFO. Choices are Sine, Saw+, Saw-, Pulse, and Tri.
LFO PlsWid (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%.
LFO Smooth
smooths (removes the higher harmonics from) the Saw+, Saw-, and Pulse
waveforms. A Sawtooth wave becomes more like a triangle wave, and a Pulse wave becomes
more like a sine wave. Range is 0 to 100%.
Distortion
Distortion effects on the Forte may also include a parametric equalizer or a cabinet simulator.
Dist Drive
applies a boost to the input signal to overdrive the distortion effect into soft
clipping. This will tend to make the signal very loud, so you may have to reduce the Out
Gain as this parameter is increased. Range is 0 to 96 dB.
Warmth
is a lowpass filter in the distortion control path. This filter may be used to reduce
some of the harshness of some distortion settings without reducing the bandwidth of the
signal. Range is 16 to 25088 Hz.
