ADVANCED MODIFIER PARAMETERS
The default modifier is 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 wah. 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.
Fortunately, a full complement of additional controls allow you to dial in all of this and more. Here is an
overview of the additional parameters you can use to create advanced modifiers:
and
determine the range of sound changes. These can be very important parameters.
MIN
MAX
EXAMPLE: The modifier for a pedal controlling DELAY MIX has MIN at "20%" and MAX at "40%".
The mix change will be limited to this range as we move the pedal, even though the parameter might
normally go from 0% to 100%.
The GRAPH shows the relationship between the source (x-axis) and the parameter (y-axis). The dot on
the graph shows changes in the source in real time.
The default modifier graph (first graph below) shows the direct (red line) relationship between the
SOURCE and the target parameter. As the source increases, so does the value of the parameter.
