Expert Modifier Settings

Modifiers also support "Expert" editing (p. 25). To
show the Expert settings for any modifier, first display
its basic Modifier page, then switch to Expert mode by
pressing Page Left and Page Right at the same time. All of the basic Modifier
settings (previous page) appear in expert mode, along with the following:
Customizing Source-Parameter Curves
Start Mid End Slope Scale
, , , , , and
which re-map the relationship between the modifier source and the value of
the target parameter. A graph shows the relationship between the source
(x-axis) and the parameter (y-axis). The dot on the graph tracks the source.
The default settings (first graph below) create a 1:1 linear relationship
(the blue line) between source and parameter. As the source changes, the
parameter tracks it directly.
The other examples below show examples of the kinds of shapes and curves
you can create using Start, Mid, End, Slope, Scale, and Offset.
Source
Damping
Attack Release
and : These values apply "damping" to slow the rate at
which the target parameter value chases the source. Attack determines the
rate of change as the source is increased, and Release controls the rate as
it decreases. At low settings, these add just a little smoothing. Try settings
of about 10 ms to "relax" a pedal or to ease the edges of a square LFO to
eliminate clicks and pops. Higher settings can cause sound changes to be
extremely slow and lazy.

PC Reset
PC Reset allows you to set a specific value for an external controller when a
preset first loads. This feature temporarily overrides the actual position of the
external controller until it is physically moved or updated.
Here's how it works:
 While setting up a modifier, turn PC Reset to "ON."
 Save the preset.
 Return to editing the effect and locate the parameter that
has the modifier applied. Normally, you wouldn't be able to
adjust the value of that parameter directly. However, with PC
Reset turned ON, you can set and save a specific value.
 This value will be used when the preset loads, until the external controller
(like a pedal) is physically moved, which then updates the parameter.
MODIFIER TIPS & TRICKS
 The same source can be assigned to multiple modifiers at the
same time. For example, one pedal might adjust Chorus Rate and
Chorus Depth at the same time — even in different ways.
 Modifiers use a very small amount of CPU power while you use
them. Test any presets which seem close to the edge.
 In addition to Auto Engage, you can also assign
modifiers to the "Bypass" parameter.
 The LFO, Sequencer, and ADSR are used as modifier sources, but
these also have parameters of their own which can be controlled
by a modifier. For example, an expression pedal can control the
rate of the Controller LFO. An Envelope can turn the Sequencer on
or off. The potential for creative sound design is immense!
 The last page of the Controllers menu contains a list of all of
the modifiers used in the current preset. When you select one of
these, you can press ENTER to open that modifier for editing.
