Effects and Effect Mode
Effects Overview
9-21
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 PC3A 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.
Highpass
allows you to reduce the bass content of the distortion content in the smaller distortion
effects that don’t have true parametric EQ. Range is 16 to 25088 Hz.
Cab Preset
selects from eight cabinet simulations which have been created based on
measurements of real guitar amplifier cabinets. The presets are: Basic, Lead 12, 2x12, Open 12,
Open 10, 4x12, Hot 2x12, and Hot 12.
Cab Bypass
switches on and off the cabinet-simulation part of the effect. When this is set to “In”,
the cabinet simulation is active; when it is “Out”, there is no cabinet action.
Cabinet HP
and
Cabinet LP
are highpass and lowpass filters to set the frequency response limits
of the cabinets. Range of both filters is 16 to 25088 Hz.
