Parameters
Scream 4 contains three main sections; Damage (distortion and other types of sound
destruction), Cut (EQ) and Body (places the sound in a resonant environment - can
serve as anything from a cabinet emulator to a wah-wah to completely new special ef-
fects) which can be switched on or off independently. The parameters in each section
are as follows:
Damage section controls
The “Damage” section is where you specify the basic sound mangling algorithm and
make settings to inflict the desired amount of damage to the sound. There are ten ba-
sic algorithms to chose from, ranging from classic distortion effects to digital-sound-
ing warping and modulation effects.
There are five controls in this section, with the following functions:
Description of the various Damage Type algorithms
Here follows a basic description of the ten Damage Types available, and what param-
eters the P1/P2 knobs control for each type:

Description
Damage button This switches the Damage section on or off.
Damage Control knob This controls the input gain which in turn determines the
amount of damage inflicted. The higher the value, the
more destruction!
When raising the Damage Control you may need to lower
the Master level to maintain the same output level (and
vice versa).
Damage Type knob This selects the type of effect - see the table below for a
description of the available damage methods.
P1/P2 knobs The functionality of these knobs vary according to the se-
lected Damage Type - see the table below for a descrip-
tion.

Description
Overdrive This produces an analog-type overdrive effect. Overdrive is quite re-
sponsive to varying dynamics. Use lower Damage Control settings for
more subtle “crunch” effects.
- The P1 knob controls the basic tone of the effect. Turn clockwise for
a brighter sound.
- The P2 knob controls Presence. Presence boosts frequencies in the
high midrange before the distortion stage which in turn affects the
character of the distortion. Turn clockwise for more Presence boost.
Distortion Similar to Overdrive, but produces denser, thicker distortion. The dis-
tortion is also more “even” across the Damage Control range com-
pared to Overdrive.
- The P1/P2 knobs control Tone and Presence, respectively - see
Overdrive for a description.
Fuzz Fuzz produces a bright and distorted sound even at low Damage
Control settings.
- The P1/P2 knobs control Tone and Presence, respectively - see
Overdrive for a description.
Tube This emulates tube distortion.
- The P1 knob controls Contour, which is somewhat like a high pass
filter, changing the tone and character of the distortion.
- The P2 knob controls Bias, which changes the “symmetry” of the
tube distortion. Setting this to the minimum or maximum value will
produce asymmetrical distortion (typical of a real-life tube amplifier),
while a 12 o’clock setting will produce symmetrical distortion (odd
harmonics only).
Tape This emulates the soft clipping distortion produced by magnetic tape
saturation and also adds compression which adds “punch” to the
sound.
- The P1 knob controls Speed, which simulates tape running at differ-
ent speeds. The higher the Speed setting the more of the original
high frequency material in the signal. Turn clockwise for a brighter
sound.
- The P2 knob controls the amount of Compression. Turning the knob
clockwise increases the compression ratio.
