Modifiers; Creating A Modifier - Fractal VP4 Owner's Manual

VP4 OWNER'S MANUAL

Modifiers

Modifiers are one of the most exciting features in the world of Fractal Audio.
They allow effect parameters to be remote-controlled or automated in real time.
With modifiers, the creative possibilities are practically limitless: control the
sweep of a volume pedal, wah, or whammy, the rate of a modulation effect like
phaser or rotary, the gain of a drive, the input gain ("send level") of a reverb or
shimmer, and more.
Starting simply, you might assign a connected expression pedal. Digging deeper,
you'll discover other "sources" to use instead of pedals: every preset has its
own LFO, Envelope Follower, Sequencer, Pitch Follower, and an ADSR "envelope
generator". You can also use a MIDI CC# message via an "External Controller."
Modifiers let you define both the range ("min" and "max") for the target
parameter. For example, a reverb mix could range from 0-100% or be restricted
to 25-40%. Advanced users can further customize with detailed curves and
additional options. Modifiers can be stacked, allowing a single pedal to control
multiple parameters, such as delay feedback, mix, and more at the same time.
You can also Each preset supports up to 16 modifiers in total.
Modifiers are easy to use but offer fantastic potential for those who want
extreme creativity or control.

CREATING A MODIFIER

The process of creating a modifier starts at the parameter you want to control.
Parameters that support modifiers are marked with a yellow circular symbol
(illustrated below). When a modifier is already assigned, the circle appears solid,
like a yellow LED that's turned ON. This symbol can appear on knobs, switches,
text parameters, sliders, or any other type of control.

TO CREATE A MODIFIER
 Select any parameter that supports a modifier. Look for the yellow circle.
 Press the ENTER button to show the Modifier screen
 On the Modifier screen select the Source you want to
use to control the parameter — for example, "PEDAL 1".
The basic modifier page also allows you to:
◽ Select a Source to control your parameter. (Learn more on the next page.)
◽ Set the Range for the parameter being controlled. For example, a Volume
pedal might be set to range from 0.0 (silent) to 10.0 (max) or might be limited
to 8.0—10.0, going from "slightly dialed down" to "full on".
◽ You might want to set up Auto-Engage (p. 39) which activates the effect
when the modifier is used.
NOTE: Ato-Engage disables normal ON/OFF footswitch control of the effect,
but eliminates the need for an extra "stomp" or separate toe-switch.
◽ You can adjust the Performance "Update Rate".
The "Fast" setting can sound smoother but uses a bit more CPU.
 Press EXIT to leave the modifier menu.
 SAVE the preset to save the modifier.
TO EDIT OR REMOVE A MODIFIER...
To edit an existing modifier, use the process above for creating a modifier.
 To remove a modifier, simply change its SOURCE to "NONE".
FAQ: Why Can't I Change a Setting once it has a Modifier?
You can't manually adjust a parameter that is under the control of a modifier.
Modifiers are shared across all channels, so plan accordingly.
In the event you want to remove a modifier and can't find it, or when a modifier
on one channel causes unexpected results on another, you can find a list of all
modifiers in the current preset in the Controllers menu. See p. 42.
