Installation
Install the Plug-in
Insert the CD into your CD-ROM drive. The Installer should start automatically.
If the Installer doesn’t start automatically, you can start it manually by opening the appropriate
file on the CD:
Mac®: Use the “.dmg” installation file
Windows®: Use the “32-bit.exe” or “64-bit.exe” installation file
Once the Installer is open, follow the on-screen instructions to install the software.
iLok License
You must download the license to your 2nd Generation iLok USB smart key before running
any program that might use this plug-in. If a valid iLok license is not present, the initial plug-in
validation scan will fail and you may not be able to run the plug-in without digging into your
system. For more information go to www.iLok.com.
Important! Your PCM Native Plug-in will not work without an authorized
2nd Generation iLok USB smart key inserted in your computer’s USB

First Look—The User Interface
Overview
When the plug-in is instantiated, you will see a window that looks something like this:
Level Meters
Fader
Area
Control Buttons
Preset
Category
Preset
Selector
Realtime
Display
Stereo/Phase
Analyzers

3
Level Meters
Shows the input, output and feedback levels. The Feedback meters measure the energy level
being fed back into the beginning of the delay line.
Preset Category
Presets for the algorithm are grouped into categories to make them easier to find. Clicking
in this area will show the list of categories. Selecting a category will load the presets for that
category in the Preset Selector.
Preset Selector
Displays the list of presets within the selected category. Selecting a preset from the list will
cause the preset to be loaded into the plug-in.
Realtime Display
Three unique visualizations help you to see inside the effect. See the “Realtime Display” section
for more detailed information.
Control Buttons
These buttons are used to compare, edit, reload and store presets. This is explained in more
detail in the “Control Buttons” section of this manual.
Stereo/Phase Analyzers
These tools provide a visual of the phase response and perceived stereo image of the
processed signal. See the “Stereo/Phase Analyzers” section for more detailed information.
Fader Area
Parameter values are shown and controlled in this area. This is explained in more depth in the
“Fader Area” section of this manual.

4
The Realtime Display
The realtime display window allows you to visualize the effect in three ways. While your ears will
always be the primary tool in choosing and adjusting presets, the displays provide a direct way to
see what’s going on. Click anywhere in the realtime display window to change the view.

5
Off
This display mode shows only the algorithm name.
It is the default view for the plug-in and requires the
least amount of CPU cycles.
3-D Voice View
This display shows a 3-D view of each individual
voice. Each voice (feedback or output) is displayed
on screen using a vertical hollow frame. The frame
is filled by the measured real-time level in the voice,
and therefore, acts as a meter (0dB = full scale). The
depth represents logarithmic delay time and the x
axis represents pan.
Frequency
This display shows the frequency levels of the left
and right output signals.
Live Impulse Response
This display shows a live impulse response of the
left and right output signals.

6
The Stereo/Phase Analyzers
These analysis tools provide visualizations of the output signal’s stereo image and phase
response.
Lissajous Figure
Window
Stereo Width Meter
Lissajous Figure Window
This window shows the width and panning of the effects stereo image. The width of the stereo
image is displayed by how far out, from center, the lines spread. Therefore, a mono effect
signal panned center would be represented by a thin vertical line and an extremely wide spread
would indicate inverted mono and may have mono compatibility problems. A rightward slant
indicates effect voices have more energy on the right output as compared to the left and a
leftward slant indicates the effect voices have more energy on the left output as compared to
the right.
Stereo Width Meter
This meter shows the perceived width of the stereo image in a different way. A mono signal
would show no level. A true stereo signal will display a wider bar, while inverted mono
will display at the maximum width. The widest signals may exhibit problems with mono
compatibility, so they should be monitored. The left and right side of this meter will always show
identical level. The greater the meter level, the wider the stereo image will be perceived.

7
The Fader Area
The fader area may be populated by up to nine faders. This illustration shows what may be
found for each fader.
Parameter
Name
Modifier
Button
Parameter
Value
Fader
Parameter Name
Shows the parameter being adjusted.
Parameter Value
Shows the current value of the parameter. This field may be directly edited.
Modifier Button
This button only appears for certain types of parameters. It controls aspects of the parameter.
Fader
Changes the value of the parameter. May be dragged, control-dragged (for higher resolution)
or may be controlled by the mouse wheel.

8
The Control Buttons
These buttons let you access all of a preset’s parameters, manage presets, and compare
changes you’ve made to the original settings.
Compare
The Compare button temporarily resets all parameters to the original preset value. It is used to
get back to the original preset and quickly audition your edits verses the original preset. When
compare is on, all parameters are frozen and cannot be changed. Turning compare off returns
you to your edits. Choosing a different preset cancels compare mode.
Edit
Clicking the Edit button enters “Pro” mode. Here you can adjust all parameters and configure
the soft row. See the “Edit Navigation and Full Edit Mode” section for more detailed
information.
Reload
Clicking the Reload button reloads the current preset, overriding all user edits.
Store
The Store button allows you to create and manage user presets. See the “Storing and
Managing Presets” section for more information.

9
Edit Navigation and Full Edit Mode
When the Edit button is clicked, an additional row of buttons appear along the lower portion of
the plug-in. Clicking one of the buttons will bring up an edit page holding parameters related
to the button name. Those parameters may be edited until the desired sound is achieved.
Click
Edit

10
The Soft Row
When the plug-in is first instantiated, a number of parameters appear. This page of parameters
is called the “Soft Row”. These parameters were chosen as being the most useful parameters
for a particular preset. In most cases, we’ve tried to make a consistent set of choices, but many
presets call for different parameters. For most people, the soft row is all that’s needed.
Customizing the Soft Row
The soft row assignments are part of the preset. You can change the soft row assignments and
store the preset as a User Preset. To do this, press the Edit button to go into edit mode then
press the button for Soft Row. The plug-in will look something like this:
1. Click
Edit
2. Click
Soft Row
3. Modifier
button area.
Click to assign
soft row
parameter.
In the modifier button area, just above the fader, you will see the name of the parameter that is
assigned to that position in the soft row. Clicking on any of these parameter buttons reveals a
list of all the algorithm’s parameters. Select a parameter (or “no selection”) from the list, and
that parameter is then assigned to the soft row. The assigned parameter is still available on its
original edit page, but now it appears in the soft row as well.
You can assign any parameter to the soft row. You can even assign the same parameter more
than once. When you’re done, store it as a User Preset and you’ll always be able to recall the
preset with your customized soft row.

11
Master Edit Page
To enter the Master Edit page, click the Edit button to display the edit page buttons, then click
the Master button. A page similar to this will appear:
1. Click
Master
Each parameter is described in the “Parameters” section starting on page 24.
The Master page allows you to adjust the master levels of the algorithm. For example, you can
adjust the overall mix level (wet/dry mix) and diffusion here.
This page also gives you global control over some of the individual voice parameters. For
example, adjusting the delay time master on this page will re-adjust the delay time parameter
for all delay voices.
Other controllable parameters on this page are: feedback diffusion, delay level master, and
delay feedback master.

12
LFO Edit Page
To enter the LFO Edit page click the Edit button to display the edit page buttons, then click the
LFO button. A page similar to this will appear:
1. Click
LFO
Each parameter is described in the “Parameters” section starting on page 24.
This page allows for control of four LFOs. The LFO waveform and rate can be set on this page.
There is a graphical display for each LFO providing a real-time visual of the LFO, based on how
the LFO waveform and rate parameters have been set.
