1. EXPRESSION PEDAL TO SPEED
This setting is primarily intended to enable control of the LFO rate with an expression pedal, but
can also be used for Envelope and Hot Hand modes. Note that when the pedal is set to
Envelope mode, the Speed Knob is divided into two regions.
2. EXPRESSION PEDAL TO SWEEP RANGE
This setting enables expression pedal control of the depth and/or direction of the envelope filter
sweeps.
To exclusively control the depth of the filter sweeps, set the knob to 12 o’clock and the ‘XD’
parameter to half of its maximum positive (+6) for upward sweeps or negative (-6) for downward
sweeps.
To exclusively control the direction of the filter sweeps, set the knob to its full counter-clockwise
position and set the ‘XD’ setting to its maximum positive position (+12). In this setting, the
expression pedal will have a maximum negative filter sweep when in its backmost position and a
maximum positive filter sweep when in its full forward position with variations in between. The
zero modulation point will occur in the center of the pedals range.
3. EXPRESSION PEDAL TO WET/DRY MIX
This setting enables expression pedal control of the wet/dry mix. As the maximum ‘dry’ setting
occurs at 12 o’clock on the Mix Knob, it is advisable to set the knob to 12 o’clock and the ‘XD’
parameter to half of its maximum positive (+6) or negative (-6) position depending on the
preferred mix settings (see MIX knob explanation on page 9 of the Owner’s Manual).
To set the maximum dry sound to the full forward position of the expression pedal, either set the
Mix Knob to its full counter-clockwise position and the ‘XD’ parameter to half of its maximum
positive position or set the Mix Knob to its full clockwise position and the ‘XD’ parameter to half of
its maximum negative position.
4. EXPRESSION PEDAL TO MODULATION
This setting is primarily intended to allow an expression pedal to control modulation in a similar
fashion to a standard wah-wah pedal. This will turn the expression pedal into a new modulation
source to be directly summed with the selected primary modulation sources of the (Envelope,
LFO, or Hot Hand).
For standard wah pedal functionality, disable the primary modulation signal by setting the Sweep
Range knob to 12 o’clock and set the ‘XD’ parameter to its desired range of positive or negative
modulation.
Many of the filter effect types feature multiple filter shapes sweeping in varied directions. To
emulate the linear sweeps of a standard wah pedal, it is advisable to select one of the less
complex filter effect types such as the Single Peak or 2 Pole Low Pass settings.
Even more unique wah pedal sounds can be achieved through various combinations of
expression pedal modulation with the primary modulation sources enabled by moving the Sweep
Range knob away from it’s neutral 12 o’clock position.
5. EXPRESSION PEDAL TO FREQUENCY
