Frequency Shifter
A frequency shifter shifts each frequency of the input signal by a fixed amount.
Unlike pitch shifters, where the frequencies are shifted by a factor, and where the 
h
armonic relations are kept, a frequency shifter alters the harmonic relations. 
Therefore, a larger frequency shift usually results in a disharmonic sound.
Furthermore, a frequency shifter alters the  frequencies by adding an offset, while a 
pitch shifter multiplies the frequencies...

NotchesHere you set the number of notches the phaser effect produces when you use 
larger amounts of Feedback.
LFO Section
LFO Waveform and ShapeWaveform  selects the bas
 ic type of waveform. Shape changes the 
characteristic of the waveform.
• Sine produc
 es smooth modulation. Shape adds additional harmonics 
to the waveform.
• Triangle  is similar in character to Sine. The waveform periodically 
ramps up and down.  Shape continuously changes the triangle...

SensitivityAll input signals are mixed do w
 n to mono before they are sent to the Envelope 
Follower. This parameter sets the optimum input level for the Envelope 
Follower.
Attack Adjusts the attack time, that is, the time the Envelope Follower needs to 
approach 
 increasing input levels.
Release Adjusts the release time, that is, the time the Envelope Follower needs to 
approach decreasi ng input levels.
Depth Determines the direction and amount of frequency...

Shimmer RateDetermines the relation between the speed of the primary and the secondary 
delay modulation. For example, 
 with a value of 10, the secondary modulation 
is 10 times faster.
Low Cut Applies a low-cut filter to the signal. Only frequencies above the set frequency 
are
 sent to the effect.
High Cut Applies a high-cut filter to the si g
 nal. Only frequencies below the set 
frequency are sent to the effect.
Level Allows you to adapt the effect signal le vel...

RatioSets the amount of gain reduction for sounds that are louder than the 
th
reshold. The higher the ratio, the more the output is lowered. For example, 
if the ratio is set to 2:1 and the amplitude of the sound is 4  dB above the 
threshold, the output 

is lowered by 2  dB. If the amplitude is 8  dB above the 
threshold, the output 

is lowered by 4  dB.
Soft Knee If this button is deactivated, sign als above
  the threshold are compressed 
instantly according to...

Peak – RMSDetermines whether the input 
 signal is analyzed according to peak or RMS 
values or a mixture of both. At a setting of 0  %, the Compressor uses Peak 
sensing only and 

at 100  %, RMS sensing only.  P
 eak means that the 
Compressor directly senses the peak level of the sound. RMS means that the 
Compressor senses the average power of the sound. Peak sensing responds 
faster than RMS sensing. Typically, Pe ak sensing is used for transient and 
RMS...

In/Out MetersShow the highest peaks of all available input and output channels.
Tube Compressor
This versatile compressor with integrated  tube-simulation allows you to achieve 
smooth and warm compression effects. The VU meter shows the amount of gain 
reduction. Tube Compressor features an internal side-chain section that lets you 
filter the trigger signal.
Drive (1.0 to 6.0)
Controls the amount of tube saturation.
Input (-24.0 to 48.0) Determines the compression...

Side-chain Activates/Deactivates the internal side-chain filter. The input signal can then 
be sh
aped according to the filter parame ters. Internal side-chaining is useful 
for tailoring how the compressor operates.
Filter section (LP, BP, and HP) If the Si
de-Chain  button is activated, you can use these buttons to set the 
filter type to low-pass, band-pass, or high-pass.

ReleaseSets the time that the gain needs to retu rn to its original level. 
 The longer the 
release time, the longer it takes  to return to the original level.
NOTE
This parameter is not available if the  Auto button is activated.
Auto
Activate this to set the release time automatically. The Limiter analyzes the 
inpu
t sound continuously to find the optimal setting.

NOTE
Brickwall Limiter is designed for the reduction of occasional peaks in the signal. If 
the Gain Reduction meter indicates constant limiting, try raising the threshold or 
lowering the overall level of the input signal.
Maximizer
This plug-in raises the loudness of audio material without the risk of clipping.
Output (-24 to 6 dB)
Determines the maximum output level. Set this to  0 dB  to 
avoid clipping.
Optimize (0 to 100) Determines the loudness of the signal....
