#12. Effects in Reason - The Scream 4 Distortion Unit


Scream 4 is the distortion effect in Reason. It is divided into three sections - Damage, Cut and BodyEach section can be enabled or disabled by the small button on the left of it`s name.


The DAMAGE section has DAMAGE CONTROL knob, controlling the amount of the effect applied, while the knob on the right of it selects the type of the effect. Each effect has two customizable options, controlled by the two knobs below. 


OVERDRIVE - Dynamic analog overdrive effect with TONE and PRESENCE (mid to high frq boosts) adjustment.

DISTORTION -  Similar to the one above, but thicker.

FUZZ - Piercing distortion effect.

TUBE - Old valve guitar amplifier emulator.

TAPE - An algorithm, emulating tape saturation clipping. The SPEED of the tape controls the brightness of the sound, while COMPRESSION controls the compression applied.

FEEDBACK - As the name implies - feedback type of distortion.

MODULATE - Ring modulation effect. The signal is multiplied by compressed and distorted copy of it.

WARP - Distorts and multiplies the incoming signal with itself.

DIGITAL - Bit resolution and sample rate reducer. You can make Nintendo-ish sounds using that.

SCREAM - High gain and high resonance band pass filter effect, followed by fuzz type of distortion.

The CUT area in the middle is a three band EQ, with low frequency, mid frequency and high frequency control sliders. 


Visual representation of the frequency range of each slider. We analyze the spectrum of a white noise signal by running it trough vocoder:



Boosting the low frequency slider to full (with 2 identical scream 4 units used, in order to show the effect more prominently):


Boosting the mid frequency slider to full:



Boosting the high frequency slider to full:


The BODY section emulates speaker cabinet effects upon the sound.


The RESO controls the resonance amount.

SCALE sets the volume of the virtual cabinet while altering the resonance. 

AUTO changes the scale parameter, based on the incoming sound.

The TYPE knob gives you the ability to select between 5 different types of cabinets.

The MASTER knob sets the volume of the already processed sound.

The effect has CV inputs on the back for controlling the Damage, P1, P2 and Scale with amount knobs next to each. It also has an Auto CV Output option.

The D-11 Foldback Distortion unit is an older distortion effect in Reason. 

It has standard AMOUNT knob and a FOLDBACK knob with a small visuals of the distortion fold back effect upon the sound.



 It has an Amount CV input on the back:
