REVerence
REVerence is a convolution tool that allows you to apply room characteristics 
(reverb) to the audio.
By recording an impulse in a room, you capture the characteristics of this room. 
Convolut
ion superimposes these characteristics to the sound. The result is a very 
natural sounding reverb. Included with this effect is a collection of high-quality 
reverb impulse responses.
Impulse Response
Allows you to select an impulse resp ons

LevelAdjusts the level of the impulse response.
Equalizer Activates the built-in three-band equalizer.
ER Tail Split Sets the split point between the early reflections and the reverb tail.
ER Tail Mix Sets the balance between the early reflections and the reverb tail. At a setting 
of
 50  % the early reflections and the tail have  the 
 same volume level. Settings 
below 50  % raise the early reflections and lower the tail, as a result the sound

ER/Tail MixSets the level balance between the early reflections and the reverb tail. At a 
setting of
  50 %, early reflections and tail have the same volume. Settings 
below 50  % raise the early reflections and lower the tail, as a result the sound 
sou

rce moves towards the front of the room. Settings above 50  % raise the 
ta

il and lower the early reflections, as a result the sound source moves 
towards the back of the room.

Low FreqSets the cross-over frequency between the low and the mid band of the 
r
everb tail. The reverb time for frequenci es below this value can be offset from 
the main reverb time with the  Low Time parameter.
Shape Controls the attack of the reverb tail. At a setting of 0  %, the attack is more 
im

mediate, which is a good setting for drums. The higher this value, the less 
immediate the attack.
Density Adjusts the echo density of the reverb tail. At a...

Multi Delay
This effect produces delays, with adjustable time, feedback, and filters.
With the  Mode parameter
 , you can set up this effect as Stereo, Cross, or 
Ping-Pong delay effect. Depending on the selected mode, the echoes repeat in 
varying patterns across the stereo panorama.
Mode
Multi Delay offers three different modes:
•Ster
eo  mode has two independent delay lines, one for the left and one 
for the right audio channel, each with a feedback path...

FeedbackSets the overall amount of feedback fo r the left and 
 right delay. Feedback 
means that the output of the delay is fe d back to its input. At a setting of 0 %, 
yo

u hear one echo. At a setting of 100  %, the echoes repeat endlessly.
Feedback L/R Offsets the amount of feedback of the  left or right delay 
 from the overall 
feedback. A factor of 1 means that the amount of feedback corresponds to 
the overall feedback. A factor of 0.5 mean s that the amount is...

GainSets the amount of cut or boost for the corresponding band.
Freq Sets the frequency that is cut or boosted with the  Gain parameter.
Q (Quality) Use this parameter to adjust the bandwi dth of 
 the mid-range peak filters from 
wide to narrow. By increasing the  Q value on the low and high shelving filters, 
you can add a dip to their shape.
• To adjust the parameters  Ga

This plug-in is an easy-to-use 3-band pa rametric equalizer that resembles the EQs 
found on typical DJ mixers. This plug -in is designed for quick sound fixes.
• To set the Low, Mid , and  Hi frequency bands, click and drag the EQ points.

Auto Filter
Auto Filter provides 2 morphable filter shapes with distortion.
The morphing between the two shapes, as well as the cutoff, can be controlled with 
a ma
nual pedal control, an LF O, or an envelope shaper.
Filter Parameters
Filter Shapes
• LP 24, 18, 12, and 6 are low-pass filters with 24, 18, 12, and 6 dB/oct. Fr
 equencies above the cutoff are attenuated.
• BP 12 and BP 24 are band-pass filters with 12 and 24 dB/oct.  Frequencies below and...

DistortionAdds distortion to the signal. The effect depends on the selected distortion 
type. At hi
 gher settings, it creates a very intense distortion effect.
NOTE
This parameter is only available for the  Tube Drive, Hard Clip , Bit Red , and 
Rate Red types.
Type
The following options are available:
• When this parameter is set to  Off, 
 the filter offers no distortion.
• Tube Drive offers a lot of character  by adding warm, tube-like 
distortion.
• Hard Clip...
