CONTROL
Sweep Mode [Auto, Dmod, LFO]
Selects the control from auto-wah, modulation source,
and LFO. For more information, see “Sweep Mode” on
page 776.
Source [Off…Tempo]
Selects the modulation source for the wah when
Sweep Mode is set to Dmod.
Manual [0…100]
Sets the center frequency when Sweep Mode is set to
Dmod and Source is set to Off.
Response [0…100]
Sets the speed of response when Sweep Mode is set to
Auto or Dmod.
Envelope Sens [0…100]
Sets the auto-wah sensitivity.
LFO
Frequency [Hz] [0.02…20.00]
This sets the LFO speed, in Hz. It applies only when
MIDI/Tempo Sync, below, is Off.
Source [Off…Tempo]
This selects a modulation source for the Frequency.
Amount [–20.00…+20.00]
This sets the Frequency modulation amount, in Hz.
MIDI/Tempo Sync [Check-box]
BPM [MIDI, 40.00…240.00]
Base Note […]
Times [x1…x32]
When MIDI/Tempo Sync is On, the LFO speed is set
by BPM, Base Note, and Times, instead of Frequency.
For more information, see “MIDI/Tempo Sync” on
page 777.
Type [Individual, Common1, Common2]
This controls whether the effect uses its individual
LFO, or one of the Common FX LFOs. For more
information, see “LFO Type” on page 777.
Common LFO Phase Offset [degrees] [+/–180]
When Type is set to Common FX LFO 1 or 2, this lets
you offset the phase from the master LFO.
WAH
Mode [Preset, Custom]
Selects either preset or custom settings.
Frequency Bottom [0…100]
Sets the lower limit of the wah center frequency when
Mode is set to Custom. p.777.
Frequency Top [0…100]
Sets the upper limit of the wah center frequency when
Mode is set to Custom. p.777.
Resonance Bottom [0…100]
Sets the lower limit of resonance amount when Mode
is set to Custom.
Resonance Top [0…100]
Sets the upper limit of resonance amount when Mode
is set to Custom.
Shape [+/–100]
This parameter specifies the sweep curve of the wah. It
applies to all control via auto-wah, Dmod, and LFO,
and lets you adjust subtle nuances of the wah effect.
Invert [Check-box]
Inverts the polarity of the sweep.
Output Level [0…100]
Sets the output level of the effect sound.
Source [Off…Tempo]
Selects the modulation source that will control the
effect output level.
Amount [+/–100]
Sets the modulation amount of the effect output level.
OUTPUT
This is the standard effects output section, with
modulatable control over wet/dry balance. For more
information, see “OUTPUT” on page 764.
018: Stereo Random Filter
This stereo band pass filter is modulated by an LFO,
using either a step-shape waveform and or a sample-
and-hold shape. The filter will also self-resonate, for
creating special effects.
