Chorus•Delay provides the trademark TC Electronic chorus sound. It recreates the 1210
Spatial Expander with its unique modulation images like Chorus, Flanging and Slap Delay
with very flexible routing and filtering facilities. Of course you can adjust the modulation
speed in BPM.

scrolling on both Windows XP and Mac OS X. Simply place the mouse over a parameter
value field and use the Scroll Wheel to increment/decrement the associated parameter-
value.

In order to help you understand the Chorus•Delay algorithm, we have grouped the
parameters in sections:
CHORUS DELAY
High Cut Filter
Chorus
Delay
Meters
Levels and Mix
Routing
The CHORUS™ algorithm is a very powerful modulation algorithm. It incorporates a
delay line, a comprehensive LFO section and two individual feedback filters
allowing you to produce some very interesting feedback effects ranging from
simple chorusing to sparkle in outer space!

Delay Mix sets the
amount of delay that is
mixed into the CHORUS
effect.
CHORUS Mix sets the balance
between the source signal and
the pitching effect. To produce
the chorusing effect, this
parameter should be set
somewhere in between, because
the CHORUS works by interacting
with the source signal.
In the Send/Return configuration, it is usually not intended to hear the direct signal.

For super-smooth results, you will want to make your chorus effect slightly darker
than the source signal, as high-pitched chorus can sometimes sound unnatural or
even unpleasant.
There are two frequency values indicated above the
display: The “S” value is the start frequency of the high
cut filter, which is the lowest frequency influenced by
the filter. The “E” value is the end value. This frequency
is where you have reached the determined attenuation.
Defines how much the input to the CHORUS is damped
in the high-frequency area which is set with the
frequency-slider. The scale of the filter is 6 dB/octave.
Sets the cut-off frequency for the algorithm’s input
filters. Use this to band-limit the CHORUS and Delay.

The direct signal is not filtered, since the direct signal must be heard through the
CHORUS.

“CHORUS” is created by delaying and then modulating the signal with a low frequency
oscillator (LFO) that sweeps the delay back and forth. This produces the rich doubling
effect. To make the effect even stronger, you can use the feedback feature to feed
already chorused signal back into the CHORUS once more!
CHORUS DELAY
Sets the Speed of the LFO
that modulates the Delay
time.
When enabled, Golden
Curve forces you to
maintain a steady
relationship between
Speed and Depth.
Basic Delay time.
The LFO actually
makes this
parameter shuttle
up and down.
LFO Phase determines
the relationship
between the left and
right channels.At 0°,
the channels follow
each other; while at
180° their
modulations are
completely contrary.
Sets the maximum
amplitude of the LFO.

Marks the frequency

high- and low-cut-off
frequencies by holding

The graph in the upper left corner visualizes the relationship between Speed and
Depth. Increasing the Depth will increase the amplitudes in the graph, while
increasing the Speed parameter will reduce the spin around time in the graph.

Short delay times and higher feedback rates are used for flanging effects, while
longer delay times and smaller feedback levels are typical for chorusing effects.
GGoollddeennCCuurrvvee
This feature helps you retain the intensity of your chorus-effect while you alter the
Speed and Depth. Increasing one of these two parameters will decrease the other
accordingly.

We recommend using the dedicated PowerCore file handling system that, apart from
recall; store and compare facilities, allows for easy exchange of entire preset folders with
other users, between Windows/Mac platforms and also between different host
applications.
FFiillee
Click “File” to open the File menu.
Load Preset: Select to load presets from the default preset location.
Save Preset: Select to save the preset in My Presets folder.
My Presets: Via “My Presets” you are able to load you own presets.
If you chose to store presets in other locations than the “My Preset” folder, these
presets will not appear in the “My Preset” drop down menu. However, you can still
navigate to, and load these presets via the Load Preset function.
PPrreesseettnnaammee
This is the name of the preset.
UUpp//ddoowwnn
The [Up]/[Down] arrow keys can be used to browse through all presets.
AA//BB
With the A/B compare function you can easily compare different parameter settings when
working with the plug-in.
PRESET HANDLING

When you start working with your preset, the A/B button is grayed out. This state
indicates that the settings in both memory locations A and B are identical - so there is
actually nothing to compare.
As soon as you touch one of the parameters, the memory location “A” will be active. All
parameter changes will be applied to memory location “A”. If you switch to memory
location “B”, you go back to the starting point, and all further changes will now be
applied to memory location “B”.
Every time you press the A/B button, you will toggle between these two memory
locations.
The A/B memory locations are temporary settings only! Saving a preset, will save the currently
selected memory location only. The setting of the other (hidden) memory location will not be
saved!
RReesseett
Click “Reset” to clear memories A/B and return to the originally recalled preset.

The following locations will describe where you can find the presets, which are stored in
a folder unique to each plug-in:

• To delete a preset file, simply move it to the “Trash” or “Recycle bin”.
• To create a new sub-folder that appears in the plug-in menu, simply create a new
folder in the plug-in folder that resides in the PRESETS folder of the plug-ins default
preset location.
A folder will not appear in the Preset File Menu unless it has at least one preset inside!
