9 MODIFIERS
MODIFIER PARAMETERS
The default modifier settings are perfectly linear and direct. You change the source and the parameter follows
precisely. But you can also tweak the relationship between source and target. Maybe you want to tune the taper
of a pedal controlling a filter sweep. Maybe you want a volume pedal which gets quieter instead of louder as you
rock it forward. Maybe you want an external footswitch to “glide” the rate of your chorus between slow and fast.
In fact, a full complement of additional controls allow you to dial in all of the above and much more. Here is
an overview of the additional parameters you can use to create advanced modifiers. Find these options on the
Modify page when you set up any modifier.
Min and Max determine the range of sound changes. These can be extremely important parameters.
EXAMPLE: The modifier for a pedal controlling Delay Feedback has Min at “10%” and Max at “50%”.
The feedback sweeps from 10% to 50 as the pedal is moved, even though the parameter normally
ranges from -100% to +100%.
Start, Mid, End, Slope, Scale, and Offset are used to create custom curves which re-map the relationship
between the modifier source and the value of the target parameter. On the Modify page, a graph shows the
relationship between the source (x-axis) and the parameter (y-axis). A 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 second two graphs below show examples of the kinds of non-linear curves you can create using Slope,
Scale, and Offset. The pages which follow contain more on using these parameters.
Attack and Release: These values apply “damping” to adjust the rate at which the target parameter value
“chases” the source. Attack determines how quickly or slowly the parameter “tracks” 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 5 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 slow and lazy.
Auto-Engage works with Off Value to create effects which turn ON or OFF automatically whenever the
source controller is moved. This is typically used with a Wah pedal so you don’t need a toe switch. (Follow
the example on p. 100 and set AUTO-ENGAGE to “SLOW POS” to try it out!) Find additional information on
Auto-Engage on p. 104 .
PC Reset sets the value of an external source when a preset first loads. This allows you to override the
actual position of an external controller until it is moved or updated. Here’s how it works: after applying the
modifier, exit to the parameter again on its Edit page. Notice that the value of that parameter can be edited
as usual. If PC Reset is ON, the value you set and then save will be used from preset load until the source is
changed (i.e. the pedal has been moved).
