Chrome Tone
User’s Manual
Congratulations on purchasing Chrome Tone, the plug-In that brings the world of custom guitar amps, boutique
outboard gear and pedal effects inside Pro Tools.
The Chrome Tone plug-In is a collection of effects that includes distortion, compression, gating, chorus, ange, EQ, wah,
tremolo, spring reverb, and tape delay. These effects can all be used together in a single stacked conguration, or as
independent effects. All the Chrome Tone effects can share the same dsp.
The Chrome Tone effects can respond dynamically to the incoming audio, side chain audio, or various MIDI events
including MIDI note and velocity, and MIDI control data. A Dynamic section, standard on the Wah, Tremolo, and Chorus
plug-ins provides a fully controllable envelope follower to modify the effect itself (the frequency of the lters in the
Wah, the gain in the Tremolo, the delay length in the Chorus). The Auto section provides periodic modulation via a low
frequency oscillator (LFO). The LFO can be synced to MIDI beat clock in a variety of tempo derivatives. The LFO rate,
shape, and depth can be further modulated by the state of the Dynamic section. The Stack conguration has separate
Dynamic and Auto sections for each of its Wah, Tremolo, and Chorus/Delay stages.
The Chrome Tone Amp has six distortion modes for everything from light grit to full shred. Distortion Drive, Type,
and Frequency controls allow ne tuning of the distortion tone. The Amp also includes a full featured noise gate,
compression and sustain circuits, low cut lters, shelving and parametric EQ, a guitar cabinet simulator (great for direct
recording), and a reverb.
The Chrome Tone Wah has much more than the standard wah pedal offers. Three types of band pass (wah) lters are
included, plus multiple low pass, high pass, and phasor lter congurations are available with 12, 24, and 36 dB/oct
slopes. All lter congurations have selectable frequency and Q values.
The Chrome Tone Tremolo allows the mixing of the tremolo’d signal and the unaffected signal. Tremolo speed-change
tremolo affects are possible using the Dynamic and Auto sections.
The Chrome Tone Chorus section has ange and two chorus modes. In the Stack conguration, there is also an analog
delay line, up to 1 second long.
Feature List:
• Power and Flexibility: Four different effect congurations are available - Amp, Wah, Trem, and Chorus, plus an all in
one Stack conguration. Many of the Chrome Tone congurations can share the same dsp chip. There are mono,
mono to stereo, and stereo version of each conguration. See the Reference section for a complete listing of all
Chrome Tone congurations and their specications.
• Double-Precision Arithmetic: at all stages of processing.
• Chrome Tone is compatible with ProTools and other DAW applications that support TDM, RTAS, and Audiosuite plug-
In formats. McDSP’s Chrome Tone plug-In operates on Mac OS X and Windows XP systems.
• Supports Digidesign’s™ ICON, Command 8, ProControl, and Control | 24, and Mackie’s™ HUI external control
surfaces.

Chapter 2:
Installing Chrome Tone
System Requirements
Operating System
Chrome Tone is compatible with both Mac OS X 10.4.x and Windows XP.
Configurations
Chrome Tone is available in TDM, RTAS, and AudioSuite congurations.
Applications
Pro Tools™ 7.x or higher is required for TDM, LE, and M-Powered systems. Additionally, a Third Party software
application that supports the Digidesign TDM, RTAS, or AudioSuite plug-in Standard may be supported. See http://www.
digidesign.com/developers/plugin_info/ for more information.
McDSP plug-ins are compatible with the entire Pro Tools™ 7 product line.
Hardware
McDSP plug-ins support any Digidesign or approved Third Party hardware supported in Pro Tools™ 7.x. This includes
HD, HD Accel, 002, and Mbox host based systems. See http://www.digidesign.com/compato/ for more specic
information.
The McDSP Mac versions are compatible with both Intel and PowerPC based computers.
The McDSP XP versions require an Intel Pentium 4 or greater processor.*
* Our XP test machines are chosen to follow the Digidesign recommended systems guide, which currently is the Dell Precision™ Workstation 670 with 2.79
GHz Xeon processor. All products are guaranteed to run on that system. Older Intel processors (i.e. Pentium III and predecessors) and AMD processors are
not officially supported, although some users have had limited success with newer AMD processors (i.e. Dual Opteron 1.79 GHZ, Athlon 64 2.20 GHz, and
Athlon 64 XP 3700). None of our XP product line will work with Pro Tools™ 5.x. Also note that our XP product line does not support MIX, although RTAS
versions will work if they exist and the rest of your system (i.e. Pro Tools™ version and processor) is compatible.

User’s Manual
Installing the Chrome Tone plug-in on Mac OS X
The Chrome Tone plug-in Package includes this manual, ReadMe and Release Notes, a folder of presets for the Chrome
Tone Plug-in, and the Chrome Tone plug-in. Two copies of the Chrome Tone Licensing Agreement are included - one
in this pdf manual and a second as a separate text le. The Chrome Tone plug-in manual requires that Adobe Acrobat
reader (or similar .pdf reader) is installed.
Both online and boxed version will come with a Chrome Tone installer that will automatically install the Chrome Tone
plug-in and its presets on your system. The authorization of the Chrome Tone plug-in is still required after running the
installer, and those steps are detailed in the following sections.
Installing the Chrome Tone plug-in and presets with the Installer:
The online version of the package has been prepared for Internet delivery, and is transmitted as a compressed le in zip
format (.zip). In Mac OS X 10.4.x, simply double click the *.zip le to unpack the installer. The boxed plug-in package
purchased at your local dealer will be on CDROM. As with the online version, these ‘physical’ versions of the Chrome
Tone plug-in package should be copied into a local folder on your system.
• Insert the McDSP ‘HD Disk,’ ‘Native Disk,’ or ‘LE Disk’ CDROM onto an available CDROM drive.
• Navigate to the Chrome Tone plug-in folder on the CDROM - the installer application is contained therein.
• Run the Chrome Tone plug-in Installer application to install (copy) the Chrome Tone plug-in, presets, and
documentation to a local folder on your system. The plug-in will be placed in the ‘Plug-Ins’ folder, and the presets
will be placed in the ‘Plug-Ins Settings’ folder.
• If a previous version of the Chrome Tone plug-in (or other HD, Native, or LE version) was already in the plug-ins
folder, it will automatically be updated (or replaced) by the installer.
Re-installing the Chrome Tone plug-in presets manually:
In you wish to restore the factory default presets, it may be useful to know how to manually re-install only the presets.
• Go to the ‘plug-in Settings’ folder:
• Root->Library->Application Support->Digidesign->plug-in Settings
• If Pro Tools™ has not already done so for you, create a folder called ‘McDSP<space>Chrome Tone’.
• Place a copy of the folder from the Chrome Tone plug-in package called ‘Presets’ into the ‘McDSP<space>Chrome
Tone’ folder. The presets are now viewable (after restarting Pro Tools™) from the settings popup menu for an
Chrome Tone plug-in.
Note it may be necessary to re-start Pro Tools™ in order for the newly added ‘Presets’ folder to be viewable from the
Settings popup inside the Chrome Tone plug-in window toolbar.

presets on your system. Double click the le to launch the installer which will install the Chrome Tone plug-in, presets,
and documentation. At any time after installation, you may access the documentation from the Windows ‘Start Menu’
under the ‘McDSP’ group.
Authorization of the Chrome Tone plug-in is still required after running the installer, and those steps are detailed in
the following sections. Note that after installing new versions of the PACE iLok drivers with the Chrome Tone plug-in
installer, you will be prompted by the Chrome Tone plug-in installer to reboot your system. If you are not prompted by
the installer, there is no need to reboot.
• Insert the McDSP ‘HD Disk,’ ‘Native Disk,’ or ‘LE Disk’ CDROM onto an available CDROM drive.
• Navigate to the Chrome Tone plug-in folder on the CDROM - the installer application is contained therein.
• Run the Chrome Tone plug-in Installer application to install the Chrome Tone plug-in, presets, and documentation to

‘plug-ins Settings’ folder.
• If a previous version of the Chrome Tone plug-in (or other HD, Native, or LE version) was already in the plug-ins
folder, it will automatically be updated (or replaced) by the installer.
Re-installing the Chrome Tone plug-in presets manually:
In you wish to restore the factory default presets, it may be useful to know how to manually re-install only the presets.
• Go to the plug-in Settings folder:
• C:\Program Files\Common Files\Digidesign\DAE\plug-in Settings\
• If Pro Tools™ has not already done so for you, create a folder called ‘McDSP<space>Chrome Tone’.

Authorizing the Chrome Tone plug-in
Authorizing with a pre-programmed iLok Smart Key
McDSP bundles such as the Classic Pack come with a pre-
programmed iLok Smart Key. Simply insert the iLok into any
available USB port on your computer. The iLok’s indicator light will
illuminate when the iLok has a proper connection. The plug-ins
included in the bundle require no further authorization steps. As
with any iLok on your system it is recommended that your iLok be
registered and synchronized with iLok.com The Chrome Tone plug-
in requires that a valid authorization is present on your iLok USB
Smart Key. With a boxed copy, this authorization is provided to you
on a plastic License Card (about the size of a credit card), with a
small punch-out iLok License Chip. After being separated from the
License Card, this iLok License Chip is inserted into the ‘key slot’ of
the iLok USB Smart Key in order to transfer the authorization from
the License Card to the iLok USB Smart Key. Note each Chrome
Tone License Card holds ONE Chrome Tone plug-in authorization.
The following instructions detail this process
Important Note: The Authorization Wizard will prompt the user to
register their iLok USB Smart Key at iLok.com. iLok.com is a service
offered by PACE Anti-Piracy, Inc. and this step is NOT REQUIRED by
McDSP to complete the authorization of the Chrome Tone plug-in.
If you choose to register your iLok USB Smart Key at iLok.com, care
must be taken to record your ilok.com account information (i.e.
write down your User ID and Password in a safe place). If your iLok.
com account information is lost, the iLok cannot be registered to
another account and unfortunately there is nothing McDSP can do
to help you. See iLok.com for more details about the benefits of
using PACE’s iLok.com service.
Authorizing the Chrome Tone plug-in from a License Card
with the Authorization Wizard:
The Authorization Wizard is used to install an authorization from
a License Card to the iLok USB Smart Key. To use the Authorization
Wizard for the Chrome Tone plug-in, perform the following steps:
• Insert your iLok USB Smart Key into a working USB port.
• On a Mac :Locate and launch the ‘Chrome Tone Authorizer’
application found in the ‘Authorize’ folder in the plug-in
package on the CDROM.
• On Windows XP, just launch Pro Tools™ to authorize the Chrome
Tone plug-in.
Note: When authorizing the Chrome Tone plug-in on Windows
XP with a new iLok USB Smart Key, you must insert the iLok USB
Smart Key and complete the Windows ‘Found New Hardware
Wizard’ before attempting to authorize the plug-in.
• Select the ‘Authorize’ button to be guided through the
Authorization Wizard.
Note: Selecting the ‘Quit’ button at any time will not authorize
the plug-in or allow it to be used for a trial period. If ‘Quit’ is
selected, the Chrome Tone plug-in will not be available in the
Pro Tools™ insert menu.
• The Chrome Tone plug-in requires that the user personalize
Use iLok License Card Dialog

User’s Manual
their copy of the plug-in. A dialog is displayed soliciting this
information.
Note that the product registration card enclosed with the plug-
in MUST ALSO be filled out as well and returned to McDSP
via mail (or fax to 707-220-0994). This additional mail-in
registration will entitle the user to future upgrades and advance
information from McDSP.
• Once the plug-in is personalized, click the ‘Next’ button to
continue.
• Check the ‘Use License Card’ box and press the ‘Next’ button.
Note: Although the Authorization Wizard may appear to allow
authorization by challenge/response, that method is currently
NOT SUPPORTED by the Chrome Tone plug-in.
• Separate the small punch-out iLok License Chip (the removable
metal and plastic tab) from the License Card by pushing the
cutout up and out with your thumb. Do not force your nger
downward.
• The iLok License Chip may now be inserted into the ‘key slot’
of the iLok USB Smart Key. If the iLok USB Smart Key does not
appear to be present on the system, ensure the iLok USB Smart
Key is connected to a valid USB port and that the green LED is
lit inside the iLok USB Smart Key. To insert the License Chip into
the iLok USB Smart Key, orient the iLok USB Smart Key’s USB end
to the left, and the loop end to the upper right. Insert the metal
chip end of the iLok License Chip (the License Chip tab should
have the metal chip side facing up towards you, not down). You
should be able to visually verify that the License Chip makes
contact with the iLok USB Smart Key metal card reader.
• The green LED in the iLok USB Smart Key will light when it is
ready to receive and transmit data.
• Upon inserting the iLok License Chip, a message will be displayed
indicating the authorization was installed successfully. Click ‘Ok’
in the message dialog.
• Once the authorization is installed on the iLok USB Smart Key,
a dialog is displayed prompting the user to register their iLok
USB Smart Key at the www.ilok.com website. The iLok.com
website was created to allow users to manage the software
authorizations on their iLok USB Smart Key. THIS STEP IS NOT
REQUIRED TO COMPLETE THE AUTHORIZATION OF MCDSP
SOFTWARE. The registration of the iLok USB Smart Key to an
iLok.com account can be bypassed by clearing the checkbox. The
user may also choose to not be asked to register again. While
iLok.com is a great resource for the iLok USB Smart Key, your
iLok USB Smart Key may only be linked to one iLok.com account.
That is, an individual iLok USB Smart Key can only be registered
to one account at a time--but a single account can have multiple
iLok USB Smart Keys. If the iLok.com account information is lost,
the iLok USB Smart Key cannot be registered to another account.
However, an iLok USB Smart Key may be transferred between
accounts if all the authorizations have been transferred off the
iLok USB Smart Key. Register the iLok USB Smart Key to an iLok.

Registering your Chrome Tone plug-in
To register your Chrome Tone plug-in with McDSP, ll out and return the product
registration card enclosed with the boxed plug-in package by mail. Registering
your product entitles you to future upgrades and advance information from McDSP.
Each individual product must be registered (even if you have multiple copies), and
it is recommended that the product be registered in a single persons name (i.e. not just the name of a studio). McDSP
has no way to know who is currently working at a particular studio. If that person should leave the company that
purchased the Chrome Tone plug-in, it is the company’s responsibility to notify us in writing that they need to transfer
ownership.
Starting the Chrome Tone plug-in:
Follow the installation, authorization, and registration instructions above, Launch Pro Tools™, and the Chrome Tone
plug-in and its presets are ready for use. Refer to the Digidesign™ Pro Tools™ Reference Guide for details on general
plug-in operation.
Exiting the Chrome Tone plug-in
The Chrome Tone plug-in is exited by clicking on the desktop or other window in the DAE application running the plug-
in, closing the plug-in window, or de-instantiating the plug-in. Pro Tools™ sessions will save instantiated Chrome Tone
plug-in congurations and their settings. Refer to the Digidesign™ Pro Tools™ Reference Guide for details on general
plug-in operation.

A Look at the Chrome Tone Amp Configuration
The Chrome Tone Amp has six distortion modes for everything from light grit to full shred. Distortion Drive, Type,
and Frequency controls allow ne tuning of the distortion tone. The Amp also includes a full featured noise gate,
compression and sustain circuits, low cut lters, shelving and parametric EQ, a guitar cabinet simulator (great for direct
recording), and a reverb.
• Six distortion modes for light to heavy distortion. Distortion Drive types include various gain staging (Narrow, Wide,
and Low), as well as many lter types for manual wah and other special effects.
• Fully programmable Gate to remove unwanted signal. Very useful for noise reduction in the signal path, particularly
when large amounts of distortion are selected. New in version 1.3, the input section now boasts a full featured pre
with more low end and several selectable Pre responses
• Compression and sustain circuits to augment the recorded performance. This section can also increase the overall
signal level in the Distortion section.
• High pass ltering, shelving and parametric EQ.
• Several new cabinet models and direct modes are now available in version 1.3.
• Spring reverb.

User’s Manual
The Controls
Noise Gate
Designed to minimize the amount of
noise heard at the output of the Chrome
Tone Amp plug-In. The Noise Gate
controls are:
• Threshold - the level at which the gate
is engaged (closed). When the input
signal drops below the threshold,
the gate closes and no more signal is
outputted.
• Attack - the rate at which the gate
opens.
• Hold - the amount of time the gate
remains open once signal level rises
above the Threshold.
• Release - the rate at which the gate
closes.
Distortion
The Chrome Tone Amp Distortion section
provides a wide range of distortion
tones from light to heavy. The Distortion
controls are:
• Drive - selected amount of gain
(emphasis) of selected frequencies into
the distortion circuit.
• Drive Type Popup - allows various gain
staging (Normal, Wide, and Low), plus
several types of lters to create wah
and other effects when adjusting the
Frequency control.
• Frequency - the frequency where the
Drive control gain is focused.
• Amount - the amount of distortion
• Level - the overall output level of the
distortion section
• Distortion Type Popup - selects the
distortion circuit type, from Light,
Light II, Medium, Heavy, Shread, and
Screamer.
Compression
Provides a compressor and sustainer
to further amplify and compress the
incoming signal. The Compression
controls are:
• Threshold - the level in dB at which
the compression starts.
• Response - the rate at which the
compressor attacks the signal once it
exceeds the Threshold value, and the
rate at which the compressor releases
once the signal level drops below the
Threshold value. The ‘C’ LED indicates
when compression is occurring.
• Sustain - the level to which the signal

A Look at the Chrome Tone Wah Configuration
The Chrome Tone Wah is a full featured modulated lter, congured as a Wah in default mode, and as a variety of
other lters as per the 14 selectable types available. The Wah, like the Tremolo and Chorus congurations, has a
Dynamics and Auto section for triggering modulation of the Wah lter (or Tremolo gain, or Chorus delay length).
The Dynamic section acts as an envelope follower with adjustable attack and decay times. A threshold determines
the triggering level of the envelope follower. The amount of effect the envelope follower has on the Wah (or other
selected lter) is determined by the Depth control. The amount of affect the envelope follower has on the Auto
section’s LFO Rate, Shape, or Depth is determined by the Mod control. Inputs to the Dynamic section are not limited
to audio - side chain audio, MIDI note or velocity, and any of the 128 MIDI controllers can be used as the modulation
source.
The Auto section is a congurable LFO (low frequency oscillator) used to modulate the Wah (or other selected lter)
with a periodic waveform. There are two waveform shapes that can be mixed in realtime, and the second shape can be
a multiple of the rst. MIDI beat clock syncing is available along with a groove control.

The Controls
Dynamic
Gives complete control over an envelope follower used to modulate the Wah
(or other selected lter) frequency. The Wah controls are:
• Threshold - the level at which the envelope follower is triggered. When
the input signal rises above the threshold, the envelope ‘opens’ at a rate
determined by the Attack control. When the input signal drops below the
threshold, the envelope ‘closes’ at a rate determined by the Decay control.
• Depth - the amount (positive or negative) the envelope follower affects the
Wah (or other lter) frequency (or Tremolo gain, or Chorus delay length).
• Attack - the rise time of the envelope follower.
• Decay - the fall time of the envelope follower.
• Mod - the amount (positive or negative) the envelope follower affects the
Auto section’s LFO Shape mix, Rate, or Depth amount.
• Split - separates the envelope follower signal into a left and right channel,
each with the reverse polarity of the other. This allows one channel to
increase the Wah lter (or other lter) frequency while the other channel
decreases the frequency.
• S/R/D - enable or disable the modulation of the Auto section’s LFO Shape,
Rate, and Depth.
• Input - selects incoming audio, side chain audio, MIDI note, MIDI velocity,
or MIDI controller (1-128) as the source from which the Dynamic envelope
follower is triggered.
Auto
Gives complete control over an LFO (low
frequency oscillator) used to modulate the Wah
(or other selected lter) frequency. The Wah
controls are:
• Shape - the mix between two selected LFO
waveforms. The two shapes can be selected
from popup menus on either side of the
Shape control. The second shape can also be a
multiple of the rst shape (1x, 2x, 3x, or 4x).
• Rate - the speed of the LFO. There is a rate
multiplier control underneath the Rate control
for 0.1x, 1x, and 10x operation.
• Depth - the amount the Auto section affects
the Wah (or other lter) frequency.
• Spread - the phase difference in the LFO for
the left and right channel, up to 180 out of
phase.
• Sync - enable MIDI beat clock syncing in a
variety of beat intervals.
• Groove - move the LFO within the MIDI beat
clock timing to allow the peaks of the LFO
waveform to hit (or miss) beat boundaries.
Input
Determines the
input gain of the
Wah conguration.
This control is also
available on the
Tremolo and Chorus
congurations.
Wah
Controls the lter type, frequency, and Q (resonance), and overall modulation
range. The Wah controls are:
• Filter Type - the popup under the ‘Wah’ text gives 14 lter options: 3 types of
band pass wah including the standard wah lter type found on many Wah
pedals, 3 high pass lters (12, 24, and 36 dB/oct), 3 low pass lters (12, 24, and
36 dB/oct), 3 phasors (2, 4, and 6 stages), a wah plus low pass lter, a high pass
plus wah lter, and an experimental wah lter.
• Freq - the frequency of the selected lter type. From this value the modulation
of the frequency is initiated.
• Q -the resonance, or peak-emphasis, of the selected lter.
• Range - the overall modulation range from the Dynamic and Auto sections.
Output
Determines the
output gain of the
Wah conguration.
This control is also
available on the
Tremolo and Chorus
congurations.

The Meters
The Chrome Tone plug-In has peak metering for the output signal of the Wah, Tremolo, Chorus, and Amp plug-ins. The
Stack congurations have a peak LED at the output of each stage.
Automation
All Chrome Tone controls are completely automatable. See the Digidesign™ Pro Tools™ Reference Guide, Automating
plug-ins section.
Presets: Using the Presets and Making Your Own
The Chrome Tone presets are inspired the pursuit of the ultimate guitar tone. Many of these presets are named for
the style of guitar playing or amplication they represent. A variety of other presets are named for their application
(‘vocal’, ‘drums’, ‘guitar’). The presets can be accessed from the Pro Tools™ “plug-in Librarian” and “plug-in Settings”
pop-up menus.
To make and save your own presets, see the “plug-in Librarian Functions” section of Digidesign™‘s DigiRack plug-ins
Guide.
A Word on Preset Compatibility
Presets for the Amp, Wah, Tremolo, Chorus, and Stack congurations of the Chrome Tone plug-In ARE interchangeable
as of version 1.3. To make older preset interchangeable, simply re-save them using Chrome Tone version 1.3 or later.
Do note Amp presets are still not compatible with Wah, Trem, and Chorus congurations, as these congurations have
few common controls.
Amp, Trem, Wah, or Chorus presets imported into a Stack conguration will only affect the Amp, Trem, Wah, or Chorus
sections of the Stack

Pre
The primary source of noise in most guitar signal paths is dc and 60 Hz hum. These unwanted
signals are automatically removed with the low cut lter in the Pre section. The low cut
frequency range extends down to 75 Hz, and a variety of Pre types are available to color the
input signal (subtle bass boosting, more gentle lter roll offs, vintage pre models).
A common use of products like Chrome Tone is to re-amp the already recorded guitar track.
Using the Pre ‘vintage’ modes, this affect can be achieved on a directly recorded guitar track.
Noise Gate
The Chrome Tone Noise Gate is designed to minimize the amount of noise heard at
the output of the Chrome Tone Amp plug-In. Large amounts of gain common to
most guitar ampliers raise the noise oor of the input signal considerably. When
the performance from the guitar or other input stops, this noise oor becomes very
audible. The Gate section automatically reduces input gain to zero when the input
signal drops below the selected threshold. The Attack, Hold, and Release controls
allow the Gate to open and close in a way that does not interfere with the actual
performance.
The Noise Gate controls are:
• Threshold - the level at which the gate is engaged (closed). When the input signal drops below the threshold, the
gate closes and no more signal is outputted.
• Attack - the rate at which the gate opens.
• Hold - the amount of time the gate remains open once signal level rises above the Threshold.
• Release - the rate at which the gate closes.
Compression and Sustain
The Chrome Tone Amp Compression section provides a compressor and sustainer to
further amplify and compress the incoming signal. The Compression controls are:
• Threshold - the level in dB at which the compression starts.
• Response - the rate at which the compressor attacks the signal once it exceeds
the Threshold value, and the rate at which the compressor releases once the
signal level drops below the Threshold value. The ‘C’ LED indicates when
compression is occurring.
• Sustain - the level to which the signal is boosted as its compressed.
• Release - the rate at which the sustain action occurs. The ‘S’ LED indicates when sustaining is occurring.
• Compression Ratio Popup - the ratio of input to output as determined by the compressor.
The combination of the compressor and sustainer create a gain-slew affect, common to many ampliers when operated
at high volume levels. The amplier attempts to restrict output levels at a maximum, while boosting lower levels to
the desired gain. Using the compressor and sustainer to further drive the Distortion section produces heavily distorted
sounds.
The compressor and sustainer can also achieve long sustained sounds, while reducing the transient signal levels (initial
string plucks for example). Instrument solos and many guitar styles benet from these effects.

Distortion
The Chrome Tone Amp Distortion section provides a wide range of distortion
tones from light to heavy. The Distortion controls are:
• Drive - selected amount of gain (emphasis) of selected frequencies into the
distortion circuit.
• Drive Type - Controls and shapes the frequencies that feed the distortion
circuit with the following shapes:
• Normal parametric bell
• Wide parametric bell
• Low Shelf
• Band Pass Filter
• Resonant peak Low pass lter
• Variable Q Low pass lter
• Resonant peak High pass lter
• Variable Q High pass lter
• Extremely tight Q parametric bell
• Frequency - the frequency where the Drive control gain is focused.
• Amount - the amount of distortion
• Level - the overall output level of the distortion section
• Distortion Type Popup - selects the distortion circuit type. Distortion types are Light I, Light II, Medium, Heavy,
Shread, and Screamer
A key element to any guitar amplication system is the sound, or ‘tone’ of its distortion section. For this reason, Chrome
Tone offers many distortion modes. The Drive control articulates the color of the distortion, allowing the selection of
the portion of the frequency spectrum incurring more distortion.
EQ, Reverb, and Cabinet Simulation
The Chrome Tone Amp Equalizer section allows further
sonic adjustments post distortion. There are 3 bands of
EQ - low shelf, parametric, and high shelf.
The EQ controls are:
• Gain - +/- 12 dB in each EQ band
• Frequency - selects the frequency value for each EQ
band
These EQ sections are taken straight from McDSP’s award winning FilterBank plug-In. While a passive EQ mode may
have been an option, the use of the active EQ in the Chrome Tone Amp gives a wider variety of sounds.
Output
The Chrome Tone Amp Output section provides reverb, cabinet, and nal output control.
The Output section controls are:
• Phase - the polarity (phase) of the nal output.
• Reverb - the amount of reverberated signal mixed with the dry signal.
• Output - the overall signal level adjustment.
• Cabinet Type - Several cabinet styles with close and room mic positions, plus two
direct modes.
The reverb algorithm in Chrome Tone is a combination of spring and ‘room tone’
reverberations. The cabinet types were created from a collection of ampliers measured and tested during the course
