Internal Controllers - Fractal Audio FX8 Owner's Manual

INTERNAL CONTROLLERS

Each of the Internal controllers can be programmed per-preset for use as modifier sources. To access pages
and parameters for these controllers, press SETUP followed by the footswitch for the Controllers menu.
Notice that some parameters of these controllers can be modified themselves for truly interactive dynamics!
LFO1 + LFO2
An LFO, or Low Frequency Oscillator,
generates control signals in the form
of a variety of familiar wave shapes or random
signals. Familiar examples of LFOs in action
include the pulsing of a tremolo, the steady back
and forth sweep of a phaser.

You can vary the overall
symmetry.
Each LFO outputs two signals, "A" and "B" and
so appears twice in the list of sources. You can

SEQUENCER
The FX8 step-sequencer generates
control patterns by looping through
2–32 "stages. " You set the

SCENE CONTROLLERS
Scene controllers provide a uniquely
powerful way to change certain sound
settings from one scene to another. These two
"virtual knobs" can be programmed individually
for each SCENE in each preset. For example, you
might assign SCENE CONTROLLER 1 to delay
feedback, with a value of 10% in SCENE 1, 30%
in SCENE 2, 5% in SCENE 3, and so on. SCENE
CTRL 2 could meanwhile be used for something
completely different.

ADSR1 + ADSR2
The two ADSR sources are "envelope
generators" with
ATTACK, DECAY,
and
SUSTAIN RELEASE
The ADSR is triggered whenever the signal level

ENVELOPE FOLLOWER
The Evelope Follower converts input
levels to control signals, responding
variably to your playing dynamics. The classic
example is a touch-wah, where the frequency of
the wah varies based on how hard you play. In
comparison, the ADSR envelope generator always
creates the same control signal, but only triggers
when you play hard enough.
PITCH DETECTOR
The pitch detector analyze the pitch of
your playing and outputs a low value for
low notes and a high value for high notes.
SELECTING A DETECTOR INPUT
ADSR, Envelope, and Pitch controllers
(plus the tuner and several other
functions) monitor only IN [PRE] by default.
If your rig is POST ONLY, where input 1 is not
used, please change the location of the GLOBAL
DETECTOR to IN [POST]. Find it on the SETTINGS
page o the GLOBAL menu under SETUP.
