LFO
Frequency
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
MIDI/Tempo Sync [Check-box]
On (checked): When MIDI/Tempo Sync is On , the LFO
will synchronize to tempo as set by BPM , below. The LFO
speed will be controlled by the Base Note and Times
parameters, below. All settings for Frequency and
Frequency Source and Amount will be ignored.
Off (unchecked): When MIDI/Tempo Sync is Off , the
Frequency settings will determine the speed of the LFO,
and the BPM , Base Note , and Times settings will have no
effect.
BPM [MIDI, 40.00…300.00]
MIDI syncs to the system tempo. 40-240 sets the tempo
manually for this individual effect.
Base Note [ … ]
This sets the basic speed of the LFO, relative to the BPM
setting. The values range from a 32nd note to a whole note,
including triplets.
Times [x1…x32]
This multiplies the length of the Base Note . For instance, if
the Base Note is set to a sixteenth note, and Times is set to 3,
the LFO will cycle over a dotted eighth note.
LFO Type
Type [Individual, Common1, Common2]
Individual : the LFO uses the Frequency and MIDI/Tempo
Sync parameters, above.
Common 1 or 2 : the LFO uses the frequency or tempo sync
of the selected Common LFO, so that you can synchronize
multiple LFO-based effects together.
For more information, see “Common FX LFOs” on
page 733.
Common LFO Phase Offset [degrees] [+/–180]
This specifies the phase difference relative to the selected
Common FX LFO. It applies only when
Type is set to
Common 1 or Common 2 .
WAH
Frequency Bottom [0…100]
This sets the wah frequency when the modulation signal
(selected by
Sweep Mode ) is at its minimum level.
To reverse the sweep direction, you can set this to be higher
than the
Frequency Top , below.
Frequency Top [0…100]
This sets the wah frequency when the modulation signal
(selected by
Sweep Mode ) is at its maximum level.
Resonance [0…100]
Sets the resonance amount.
Low Pass Filter [Check-box]
Switches the wah low pass filter on and off.
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 762.
