Both Systems Include:
The E-MU 1010 PCIe Card is the heart of all three systems. Its powerful hardware DSP
processor allows you to use over 16 simultaneous hardware-based effects, which place
minimal load on your computer’s CPU. The E-MU 1010 PCIe Card also provides eightchannels of ADAT® optical digital input and output, as well as a S/PDIF stereo digital
input and output.
The PatchMix DSP mixer application is included in all the systems. PatchMix DSP
delivers unmatched flexibility in routing your audio between physical inputs and
outputs, virtual (ASIO/WAVE) inputs and outputs and internal hardware effects and
buses—no external mixer needed. You can add digital effects, EQs, meters, level
controls and ASIO/WAVE sends anywhere you like in the signal chain.
Because the effects and mixing are hardware-based, they don’t add latency when you
record. You can even record a dry signal while monitoring yourself with effects! (See
“The Order of Effects” on page 57.) Mixer setups can be saved and instantly recalled for
specific purposes such as recording, mixdown, jamming, special effect setups, playing
games, watching DVDs, or general computer use.

Setting Up the Digital Audio System
Please read the following sections as they apply to your system as you install the E-MU
1010 PCIe, paying special attention to the various warnings they include.
Prior to installing the hardware, take a few moments to write down the 18-digit serial
number, which is located on the back of the box and on the 1010 PCIe Card. This
number can help EMU Customer Service troubleshoot any problems you may
encounter—by writing the number down now, you’ll avoid having to open your
computer to find it later on.
Safety First!
• To avoid possible permanent damage to your hardware, make sure that all connec-
tions are made with the host computer’s power off. Unplug the computer’s power cable to make sure that the computer is not in sleep mode.
• Take care to avoid static damage to any components of your system. Internal
computer surfaces, the E-MU 1010 PCIe board and the interfaces are susceptible to
electrostatic discharge, commonly known as “static.” Electrostatic discharge can
damage or destroy electronic devices. Here are some procedures you can follow
when handling electronic devices in order to minimize the possibility of causing
electrostatic damage:
• Avoid any unnecessary movement, such as scuffing your feet when handling
electronic devices, since most movement can generate additional charges of static
electricity.
As you install
hardware components,
observe the following
general precautions to
avoid damage to your
equipment and yourself.
• Minimize the handling of the PCIe card. Keep it in its static-free package until
needed. Transport or store the board only in its protective package.
• When handling a PCIe card, avoid touching its connector pins. Try to handle the
board by its edges only.
• Before installing a PCIe card into your computer, you should be grounded. Use a
ground strap to discharge any static electric charge built up on your body. The
ground strap attaches to your wrist and any unpainted metal surface within your
computer. If you don’t have a ground strap, you can ground yourself by touching
the metal case of another piece of grounded equipment.

Note About Windows Logo Testing
When you install the 1616M PCIe drivers, you will see a dialog box informing you
either that the driver has not been certified by Windows Hardware Quality Labs
(WHQL), or that the driver is signed by Creative Labs, Inc, and you will be asked if you
would like to continue with the installation.
The 1616m PCIe audio drivers are not certified by WHQL because the product does not
support some of the features that the Microsoft Windows Logo Program requires, most
notably Universal Audio Architecture (UAA) and Digital Rights Management (DRM).
Despite this, the 1616M PCIe audio drivers have been rigorously tested using the same
test procedures that a WHQL qualified driver requires, and it passes in all of the other
important categories, including those that measure the relative stability of the driver.
So, it is perfectly safe to install these drivers on your computer.

The MicroDock
Front Panel Connections
Preamp Section
The front panel mono Mic/Line inputs A & B can be used as balanced microphone
inputs, hi-Z guitar pickup inputs, or line level inputs. The Neutrik combination jack
accepts microphones using a standard XLR connector or line level/hi-Z inputs (such as
an electric guitar) using a standard 1/4 inch TRS/TS connector.
Each preamp has a level control which sets the preamp gain from 0dB to +65dB for the
XLR input and from -15dB to +50dB for the Hi-Z line input. The line markings around
the knobs are calibrated in 10dB increments. The heavy hash marks on the gain
controls indicate unity analog gain to the converter inputs (~5dBV input = 0dBFS
output).
Phantom Power
Caution: Some
microphones (notably
ribbon types) cannot
tolerate phantom power
and may be damaged.
Check the specifications
and requirements of your
microphone before using
phantom power.
A phantom power switch enables +48 volt phantom power supplied to both microphones. A red LED illuminates to indicate phantom power is enabled. The audio mutes
for a second when phantom power is turned on. After turning phantom power off, wait
two full minutes before recording to allow the DC bias to drain.
See “Phantom Power”
for additional information.
Each microphone input has its own input level meters and clipping indicators. The
LED meters indicate signal presence. Adjust the input gain so that the yellow LEDs are
illuminated. The red Clip LED indicates that the gain is set too high and the signal is
clipping the input. These LEDs monitor the signal directly at the analog-to-digital
converters and before any processing by the rest of the system. When setting the levels
for signals being sent into the MicroDock, the red clip indicator should never flash.
S/PDIF Digital Audio Input & Output
RCA phono jacks are standard connectors used for coaxial S/PDIF (Sony/Philips
Digital InterFace) connections. Each jack carries two channels of digital audio. The
MicroDock sends or receives digital audio data at 44.1k, 48k, 88.2k, 96k, 176.4k or
192k sample rates. Data is always transmitted at 24-bits, but lower word widths can be
read. The word clock contained in the input data stream can be used as a word clock

Headphone Output & Volume Control
The headphone output drives standard stereo headphones and the adjacent volume
control sets the listening level. The headphone amplifier can drive headphones with
impedance as low as 24 ohms. The headphone output uses a high-current version of
the high-quality output amplifiers used on the other channels. For this reason it has a
very clean signal that can be used as another stereo output if you need it.
Note: PatchMix DSP
does not support AC3
passthrough at this time.
4 balanced 24-bit, line-level, analog inputs are provided (1L-1R, 2L-2R). These can be
used to input any line level signal from keyboards, CD-players, cassette decks, etc. The
analog inputs are assigned to mixer strips in the mixer application. The line level inputs
can be set to accommodate the consumer -10dBV standard, or the pro audio +4 dBu
standard in the I/O screen of the Session Settings dialog box. See “I/O Settings”.
The maximum input level is 18dBV (=20.2dBu).
Either TRS balanced or TS unbalanced cables can be used. The line-level inputs are all
servo-balanced, enabling them to convert unbalanced signals to balanced signals
internally to reduce noise. See page 115
cables and connectors.
for additional information about unbalanced
Phono Inputs & Ground Lug
The RCA Phono inputs feed an RIAA equalized preamp designed for moving magnet
type phono cartridges with 60 dB of gain. Connect the ground lead from your turntable
to the ground lug to prevent hum.
The phono inputs SHARE line level inputs 2L and 2R. Inserting a plug into Line Input 2
disconnects the turntable preamp from that channel. Do NOT leave your turntable
connected when using inputs 2L and 2R, since this can cause a ground loop.
Important: Do NOT plug in line level signals to the turntable inputs. The turntable
inputs are designed to accept the extremely low-level signal from a phonograph
cartridge. Use RCA to 1/4” adapters to connect line level signals to the line level analog
inputs.
Line Level Analog Outputs
Six balanced 24-bit, line-level, analog outputs are provided (1-3). Output pair 1 is
designated as the Monitor Output and is fed by the monitor bus of the PatchMix DSP
mixer application. We suggest that you plug your speakers in here. Special anti-pop
circuitry mutes the analog outputs when power is turned on or off.
Like the analog line inputs, either TRS balanced or TS unbalanced cables can be used.
Balanced cables provide better noise immunity and +6dB higher signal level. The
output line level can be set to accommodate the consumer -10dBV standard, or the pro
audio +4 dBu standard in the I/O screen of the Session Settings dialog box. See “I/O
Settings”.
The maximum input and output line levels are matched when the input and output
settings are set to the same mode (pro or consumer) in the I/O preferences screen.
Important!
It’s a good idea to MUTE
the Dock In strip 2L/2R in
the PatchMix DSP mixer if
nothing is plugged in to
these jacks. The turntable
preamp has a very high
gain (60dB) and can add
extra noise to your mix/
monitor bus.
Balanced Cables:
You should ONLY use
balanced (TRS) cables if
BOTH pieces of
equipment use balanced
connections. Connecting
balanced cables between
balanced outputs and
unbalanced inputs can
actually increase noise
and introduce hum.

PatchMix DSP
The PatchMix DSP Mixer is a virtual console which performs all of the functions of a
typical hardware mixer and a multi-point patch bay. With PatchMix, you may not even
need a hardware mixer. PatchMix DSP performs many audio operations such as ASIO/
WAVE routing, volume control, stereo panning, equalization, effect processing, effect
send/return routing, main mix and monitor control and allows you to store and recall
these “Sessions” at will.
To Invoke the PatchMix DSP Mixer

Overview of the Mixer
Mixer Window
The Mixer consists of four main sections.
Application Toolbar Lets you manage sessions and show/hide the various views.
Main SectionControls all the main levels, aux buses, and their inserts. This section also has a “TV”
which shows parameters for the currently selected effect and the input/output
patching. It also shows the session’s current sample rate and whether it’s set to
internal or external clock.
Mixer StripsThis section is located to the left of the Main Section and shows all the currently
instantiated mixer strips. Mixer strips can represent Physical analog/digital inputs, or
Host inputs such as ASIO or Direct Sound. Mixer strips can be added or deleted as
necessary. This section can be resized by dragging the left edge of the frame.
Effects PaletteThis popup window is invoked by pressing the FX button in the toolbar. Iconic
representations of all effects presets are shown here, organized by category. From
this window, you can drag and drop effect presets into the insert slots available on
the mixer strips and main section aux buses and main inserts.

The Session
The Session
The current state of the PatchMix DSP mixer (fader settings, effects routings…everything!) can be saved as a Session. Whenever you create or modify a mixer setup, all you
have to do is Save it to be able to recall it at a later time.
Before you begin using PatchMix DSP, you need to set it up to be compatible with the
other software applications you may be running. The most important consideration is
your system sample rate. PatchMix DSP and any applications or other digital gear you
are using must be set to the same sample rate. PatchMix DSP can run at 44.1kHz,
48kHz, 88kHz, 96kHz, 176.4 kHz or 192kHz, but its complete set of features are only
available at 44.1kHz or 48kHz. See
Once the sample rate is set, you can only easily switch between 44.1k and 48k. You
cannot switch between 44/48k and 88k/96k/176k/192k. With a change to these
higher sample rates, you must start a new session.
You can also set up an external sync source, thereby obtaining the sample rate from
some other device or application. External sync can be obtained from the ADAT input
or S/PDIF input. If the session is set at 44.1kHz or 48kHz and the external source is
coming in at a higher rate (such as 96k), the Sync Indicator will be extinguished (off),
but PatchMix will attempt to receive the external data. The two units are NOT sample
locked however, and you should correct this condition to avoid intermittent clicks in
the audio. Always check for the presence of the LOCKED indicator whenever you are
using a digital interface.
PatchMix DSP comes with several session templates to choose from so when you create
a new session you can either create a “blank” session based around a designated
sample rate, or select from a list of template starting points.
In a PatchMix DSP session the number of strips in the mixer is dynamically configurable. This allows you to create only those strips you need up to a maximum number
determined by available DSP resources and available inputs.
“Using High Sample Rates” on page 111 for details.
Important: When
using any form of digital
input, you MUST
synchronize the Digital
Audio System to the
external digital device
(S/PDIF/ADAT).
New Session
You create a new session by clicking the “New Session” button in the PatchMix DSP
main Toolbar. The following dialog box appears.

Page 33
You can now select one of the factory template sessions. The factory templates are preprogrammed with specific setups such as audio recording or mixing. The selector tabs
categorize Template Sessions into three groups based on sample rate, 44.1k/48k, 88k/
96k, or 176k/192k.
You can create your own templates by simply copying or saving sessions into the
“Session Templates” folder (Program Files\Creative Professional\E-MU PatchMix
DSP\Session Templates).
There is also a Comment area that you can use to give yourself some clue as to what
you were thinking when you created the session.
Selecting a Session at 176.4kHZ or 192kHz
When operating at 176.4k or 192k sample rates, the number of I/O channels are
slightly reduced. At these high sample rates you must select one of three types of
sessions each containing a different I/O configuration. Please see
page 111 for details.

Get in the habit of saving the session whenever you have created a special mixer setup.
This will make your life much easier as you can recall a setup for many different audio
modes such as: recording, mixing, special ASIO routings, etc.

4 - The PatchMix DSP Mixer
The Session
The System Settings include the following:
• Internal/External Clock Selects between internal or external word clock source
as the master clock source for the system
• Sample RateSelects the sample rate when using internal clock.
Your choices are: 44.1kHz, 48kHz, 88.2kHz, 96kHz,
176.4kHz, 192kHz.
Note: if set to
“External” without an
external clock present,
PatchMix DSP defaults to
the internal 48kHz clock
rate.
• External Clock Source
(ext. clock only)
Select from: ADAT, or S/PDIF as an external sample
clock source.
Using External Clock
Whenever you are using any digital I/O such as ADAT or S/PDIF, one of the digital
devices MUST supply the master clock to the others. This master clock runs at the
system sample rate and can be embedded into a data stream such as S/PDIF or ADAT.
Common symptoms of unsynced digital audio include, random clicks or pops in the
audio or failure of the digital stream to be recognized. Always check for the presence
of the “LOCKED” indicator whenever you are using a digital interface.
If an External Clock is interrupted or switched after the Session has been created
(except between 44.1k <-> 48k), the “LOCKED” indicator will be extinguished and
PatchMix will attempt to receive the external data. The two units are NOT sample
locked however, and you should correct this condition to avoid intermittent clicks in
the audio.
I/O Settings
You can set the level (-10dBV or +4 dBu) for each pair of analog outputs and the input
gain setting for each pair of analog inputs.
An output setting of +4 provides the most output and is compatible with professional
audio gear. Balanced output cables also provide a +6dB hotter signal than unbalanced
cables when used with balanced inputs. Do NOT use balanced cables unless your other gear has balanced inputs. See
Appendix for more information.
“Cables - balanced or unbalanced?” in the
Comparison of -10dBV & +4dBu Signal Levels
0 dBV = 1V RMS 0dBu = .777V RMS
An input setting of -10 is compatible with consumer audio gear and works best with
low level signals. (-10dBV is approximately 12dB lower than +4dBu.) Choose the
setting that allows you to send or receive a full scale signal without clipping.
Setting correct input and output levels is important! You can measure the level of an
input by inserting a meter into the first effect location in the strip. Adjust your external
equipment outputs for the optimum signal level. See

Mixer Strip Creation
PatchMix DSP is a dynamically configurable mixer. Each mixer session can contain an
arbitrary number of strips up to a limit set by the number of available input sources
and available DSP resources.
You must create a strip for each mono or stereo audio input, and for each ASIO stream
you wish to use in your software application. This is important because outputs will
not appear in your software application until you have created ASIO strips in PatchMix.
• Host refers to a computer application such as Cubase.
• Physical refers to a hardware input or output such as an output jack.

Multichannel WAVE Files
The 1616m supports 2 channels of WAVE recording and 8 channels of multichannel
WAVE playback. The WAVE channels are available for the following types of WDM
devices:
• Classic MME
• DirectSound
• Direct WDM / Kernel Streaming (KS)
DirectSound and the WDM/KS interfaces allow up to 8 channels of Wave Out while
the classic MME interface only exposes 2 channels.
The WAVE channels operate at all sample rates. For additional information about
WDM behavior at high sample rates, see page 113
.
See “Pre or Post Fader
Aux Sends” on page 48.
192kHz/96kHz DVD-Audio disks are protected against digital copying. Most DVDAudio disks contain duplicate 48kHz audio tracks which will play back on the 1616.
Windows Media Player/DVD/Surround Sound Playback
Select DirectSound as the output format when using Windows Media Player and other
DVD player applications.
Eight channel WAVE playback supports either 5.1, 6.1 or 7.1 surround audio. However,
the 1616M is best suited to play 5.1 surround, since it only has 6 analog outputs. (You
could play back 7.1 surround audio by using an external S/PDIF to Analog Converter.
Create a 7/8 WAVE strip and insert a Send to S/PDIF Out.)

effects can be inserted in series. The signal flows through the inserts from top to bottom. If a Send is below a DSP effect, the effect will be applied to that Send. If the
Send is placed above the DSP effect, the Send will be Dry (without effects).
The Inserts are also used to patch your audio inputs into ASIO/WAVE and external
equipment. ASIO/WAVE Sends, External Sends and External Send/Returns can be
dropped into the insert section to route the signal anywhere you want.
The Insert/Patch Bay is incredibly flexible. Want to send the input of the strip to your
software recording software? Just insert a HOST ASIO Send into the insert section of
the strip. That input is now available in your ASIO software.
Suppose you wanted to record a submix of several inputs. Simply place a HOST ASIO
SEND into the Aux Insert section and turn up the Aux sends on the input channels you

ASIO Direct Monitor Send/Return
This type of insert send breaks the signal at the insert point and sends it out to the
selected ASIO Host Input destination (such as Cubase or Sonar). A return source signal
is also selected which returns the signal to the channel strip from an ASIO Host Output.
The ASIO Direct Monitor Send/Return is unique in that it utilizes ASIO 2.0 zero-latency
monitoring. In order to utilize this feature, Direct Monitoring must be enabled in
the audio recording application.
While recording, the Direct Monitor Send/Return routes the signal to the recording
application, but monitors directly from the input to eliminate latency. During
playback, the recording application automatically switches the Direct Monitor Send/
Return to monitor the recorded track.

Meter Inserts
Keeping track of signal levels is important in any audio system, be it analog or digital.
You want to keep the signal levels running as close to maximum in order to achieve
high resolution and low noise. On the other hand, you don’t want the signal level so
high as to cause clipping. To help you maintain optimum signal levels, we have
included Peak Level Meters, which can be dropped into any insert location.
The insert meters are of the “peak hold” type. The topmost bar in the meter holds its
highest level for a second to let you see transients that would otherwise be too quick for
the eye.
The peak meters are also color-coded to indicate the signal strength. The chart below
outlines the meanings of the colors. Avoid lighting the topmost red bar, as this
indicates distortion of the signal. Click on the clip indicator to turn it off.
Meter ColorIndicates
RedIndicates signal clipping.
YellowGood strong signal level.
GreenSignal is present.
One of the most obvious uses of the insert meters is to set input levels. On the analog
inputs, the analog-to-digital converter (ADC) is one of the most critical points in the
signal path. You want the input signal level to drive the 24-bit ADCs into their
optimum range without clipping. A reading of 0dB on an input meter indicates signal
clipping.
Level
10203040506070
--12dB
Each bar of the meter equals 1dB. The yellow bars begin at -12dB below full scale.
42Creative Professional
Page 43
The insert meters are also useful to monitor incoming digital signals such as ADAT,
ASIO or S/PDIF to make sure the mixer is receiving a proper signal level. They’re also
great for troubleshooting, since you can place them virtually anywhere in the mixer.
To Insert a Meter
1. Right-Click on an Insert location of the mixer strip. A pop-up dialog box appears.
2. Select Insert Peak Meter. A stereo peak meter appears in the insert location.
3. Select Effect in the Main Section. The meters are now shown in high resolution in
the TV screen.
To Set the Input Levels of a Strip
1. Select the topmost Insert location on a mixer strip and insert a meter (see above).
2.
Left-click on the meter insert to see the meter in the TV screen.
3. Feed your audio signal to the input of the mixer strip. The meter should now show
the signal level.
4. Adjust the output level of the external device (synthesizer, instrument, preamp,
etc.) feeding the MicroDock. The meter should be in the yellow region most of the
time with occasional forays into the red. If the clip indicator ever comes on, reduce
the signal level.
5. Each analog input pair has its own Input Pad (-10dBV or +4dBu) which controls
the input signal range. Changing the I/O settings can add or subtract 12dB. Check
these settings if you cannot set the proper input level. See “I/O Settings”
.

Making the Best Possible Recording
Making a good digital recording is easier than ever thanks to the high resolution 24-bit
A-D converters on your Digital Audio System. These converters are much more
forgiving than the 12-bit or 16-bit converters of the past. Even so, to get the best perfor
mance possible, you'll need to follow a few basic guidelines.
First, whenever you input an analog signal to the Digital Audio System, make sure that
you're feeding the A-D converters with an optimum signal level. The quality of a digital
recording is directly related to the signal level you feed into the A-D converters. If the
analog input level is set too low, you lose resolution—if it's set too high, the A-D
converters will clip.
To measure the input level, simply add an insert meter to the channel strip in PatchMix
DSP. These meters are accurately calibrated to display 1dB for each bar on the meter.
You can enlarge the meter view by clicking on the insert meter in a strip and selecting
the “Effect” button at the top of the TV screen.
The “I/O Settings” in the Digital Audio System allow you to set the input levels to
-10dBV (consumer equipment level) or +4dBu (professional equipment level) for each
analog input. This control sets the overall input level to match your other gear, but to
get the best possible recording you need to fine tune the level further.
In order to supply the correct input level, you’ll need to adjust the output of your
analog source (electric instrument or preamp) so that the input level comes close to
0dB without ever going over.
Play your input source signal while watching the insert meter in the strip. The signal
should go into the yellow area frequently, but never into the red. Adjust the level of
your source until you have a good level. If the signal is way too strong or too weak, you
-
E-MU PCIe Digital Audio Systems43
Page 44
4 - The PatchMix DSP Mixer
Mixer Strip Creation
may have to go back and adjust the I/O Settings. Choose “-10” if the input signal is too
weak and “+4” if the signal is too strong.
Digital audio has NO headroom past 0dBFS (FS = Full Scale) and will “hard clip” if the
signal exceeds 0dBFS. Hard clipping sounds bad and will ruin your recording. Hard
clipping occurs because at 0dBFS, all 24 bits are turned on and the A-D cannot measure
any higher level. Analog tape, unlike digital, can be driven past 0dB, with some degradation of the signal.
The MicroDock includes a pair of analog Soft Limiters on the preamp inputs, which
can be turned on or off for each channel in the I/O Settings. The soft limiters automatically turn down the gain whenever the signal level exceeds -6dB below Full Scale.
Below this level, the limiters are completely out of the circuit. The soft limiters allow
you to encode a hotter signal without fear of hard clipping the input. This provides
increased resolution and a better recording. When recording drums, piano and vocals,
occasional peak transients can be tamed by the soft limiters, allowing you to supply the
best possible signal into the MicroDock’s ultra-high-quality A-D converters.
The Digital Audio System includes Insert “Trim Pot” controls, but since they adjust the
signal level AFTER the signal has been digitized, this will not recover any lost
resolution. It’s far better to set the input level correctly in the first place. Trim Pots can
be used in emergency situations if there's no other way to get a hot signal in. They are
designed to optimize the signal levels feeding effect plug-ins.
Trim Pot Insert
The Trim Pot Insert allows you to adjust the level of a signal in an insert location. The
trim pot provides up to ±30dB of gain or attenuation and a phase inverter. The trim pot
also has a built-in stereo peak meter after the control.
Gain/Attenuation
Phase Invert
Meters
You might use a trim pot to boost or attenuate a send or return from an external effect,
or to drive an effect device. Certain effects such as the Compressor, Distortion, and
Auto-Wah are very level dependent and like to see a good, strong input signal. If you
are working with a weak signal, you can improve the performance of these effects
inserting a trim pot and boosting the gain.
Trim pots can be used to boost the level of analog line level inputs in a pinch, but it’s
much better to boost the signal level before the A/D converters in order to get maximum
resolution and signal-to-noise ratio from the converters.
The phase invert switch inverts the polarity of the signal. It is generally used to correct
for balanced lines and mics that are wired backwards.

Test Tone/Signal Generator Insert
The test tone/signal generator insert is a handy troubleshooting aid which outputs a
calibrated sine wave, white noise or pink noise. This tool, in combination with an
insert meter, allows you to accurately measure the signal gain or attenuation of an
internal or external device. The test tone can also be quite handy for tuning up musical
instruments.

sound sources for measuring speaker response.
Using the Test Tone and Meter Inserts for Troubleshooting
Sometimes it’s useful to have a continuous tone to verify that you have the signal
path routed correctly in hardware or software. First insert a Test Tone and/or a
Meter(s) into a strip, then follow the tone through the system by ear or by moving
the meter. A test tone is quite handy when first setting up your recording software.

Aux Section
The Auxiliary Sends tap the signal from the channel strips and sum them together
before sending the mix to the Auxiliary Effects section. In a traditional mixing console,
aux sends are used to send part of the signal to outboard effect devices, then return the
effected signal back into the mix using the effect returns. This is called a Sidechain Routing because the aux signal takes a detour through the effects before being summed
back into the main mix. Sidechain effects are usually effects that you might want
applied to several channels, such as reverb.
Incidentally, the wet/dry mix of effects in the Aux Sends should normally be set to
100% wet. This is because you will be adjusting the effect amount using the Aux Return
control instead. If you have more than one effect in an Aux Bus, ignore the preceding
advice as the wet/dry controls can be used to mix the amounts of your multiple effects.

You can think of the Aux Sends as two extra mixing buses because that’s exactly what
they are. These two mixes can be routed anywhere, such as to a physical output or an
ASIO pair. You could route one of the Aux buses to the Monitor out to create a monitor
mix while sending the main mix off to your audio recording software.

Pre-Fader selected, you may still hear the effected signal returning from one of the Aux
Buses with the volume fader turned down.
With the Pre-Fader box selected, the Aux Send levels are completely unaffected by the

we use an unconventional pan section with two
pan pots – one for the left part of the signal and
one for the right part of the signal. This feature
allows you to independently position both sides
of the stereo signal. A conventional stereo balance
control only allows you to turn down one side or
the other.
The Mute button does just what you would

multiple solo buttons are pressed, you will hear all
soloed channels and the non-soloed channels will
all be muted.
The mute status is remembered if a muted channel
is soloed. When the channel solo is turned off, the
channel reverts to being muted.
The Level Control for the strip is an attenuation
control that can also provide up to +12dB of gain.
0db is the unity gain setting. You can also type
numeric values into the displays to set the level.
At the very bottom is the Scribble Strip text area,
into which you can type any short piece of text,
thus naming the strip, i.e. “vocals”, “bass”,

The Main Bus can also have a chain of effects inserted. (You might put an EQ here to
equalize your entire mix or add an ASIO or WAVE send to record the mix.) Note that
the Main Output level control comes before the Monitor Level so that you can control
the monitor level without affecting the level of your recording mix or main mix. There

range the “LOCKED” LED will extinguish.
If the external clock source makes a radical sample rate change from the lower rates of
44.1k/48k to a higher rate or between any of the higher rates, the hardware automati
cally switches to internal 48kHz clock until the proper external clock is restored. The
“LOCKED” LED will be off and the two units are NOT synchronized. Always check the
“LOCKED” LED when using an external clock source to make sure you are samplelocked.

Main Inserts
The main inserts allow you to apply effects to the main stereo signal coming out of the
mixer (both mains and monitor). You might want to apply EQ or a compressor here.
These inserts work just like the other insert locations—just drag and drop effects from
the palette or right-click and add Sends, Sends/Returns. etc.

Main Output Fader
The main output fader controls the level of the main output (and the Monitor output
as well since it is downstream from this control). The normal setting for this control is
at unity or 0dB, but the control allows you to add up to +12dB of gain. High output
levels may cause clipping on outboard amplifiers or other equipment.
Output Level Meters
This stereo bar-graph meter reflects the digital level at the output of the mixer. The
topmost red bar represents 0 dB or a full-scale digital signal. The peaks hold for a
moment so that short transients can be monitored. Each bar = 1dB.
Monitor Output Level
This control adjusts the monitor output level. Keep in mind that since the monitor level
control comes after the Main Output Fader, nothing will be heard from your monitors
if the main level is turned down.
Monitor Balance Control
This control sets the relative volume of the stereo monitor outputs and works just like
the balance control on your home music system. This control is primarily used to make
the volume from each speaker sound equal if you are not sitting exactly in the center of
the two speakers.
Monitor Output Mute
This button completely cuts off the monitor output and provides a convenient way to
instantly kill all sound without having to re-adjust the monitor level later. When the
telephone rings, just hit the monitor mute to cut the noise.

Overview
PatchMix DSP comes complete with a host of great core DSP effects including
Compressors, Delays, Choruses, Flangers and Reverb. Each 32-bit effect has various
parameters for editing, as well as factory presets. You can also create and save as many
of your own effect presets as you wish.
Since the effects are implemented in hardware, they don’t place any load on your host
computer. This allows your valuable CPU cycles to be used for other applications or
software plug-ins. The effects are only available at the 44.1 and 48kHz sample rates.
There is a finite limit to how many effects you can use at the same time. As you use up
the PatchMix DSP resources, certain effects will appear “grayed out” and cannot be
added to the mixer. Complex effects such as reverb use more DSP resources than say a
1-Band EQ. If you continue to add effects, all of the DSP resources will eventually be
used up. For more detailed information, see
The Effects Palette
Click the FX button on the toolbar to bring up the Effects Palette. The Effects Palette
contains two types of folders. The “Core Effects” folder contains the effect algorithms
themselves. This folder cannot be modified. The other folders contain “Effects Chains”,
consisting of two or more effects grouped together. You can also add, delete, or modify
Effects Chains and the folders that contain them. For more information on Effects
Chains, see
“FX Insert Chains” on page 56.

FX Edit Screen
Click on an FX Insert to display the parameters for that effect. If an insert effect is not
selected, the FX display will read “No Insert.”
Most effects have a wet/dry mix parameter to control the ratio of effect-to-plain signal.
The wet/dry setting is stored with the FX preset. The effect parameters vary with the type
of effect. Generally if an effect is placed in an Aux Send, the wet/dry mix in the effect
should be set to 100% wet since the Aux Return amount controls how much effect is
applied.
The User Preset section is located at the bottom of the FX Edit screen. User presets are
variations of the main effect and can be edited, deleted, renamed or overwritten as you
wish.

DSP Resource Usage
There are two main factors which determine the total number of effects available for
use at any given time: Tank Memory and DSP Instructions. Using too much of either
resource will cause effects to be unavailable (grayed out) in the FX menu. In addition,
the strips themselves use DSP Instructions, so only create strips that you actually need.
Tank memory is the memory used by delay-based effects such as reverb and digital
delays. All the reverbs and delays aside from the Mono Delay 100 and Stereo Delay 100
use varying amounts of tank memory.
The DSP instructions are used by all the effects. Effects with multiple stages, such as
multi-band EQs or the speaker simulator use more DSP instructions than a 1-Band EQ.
Delay memory tends to get used first, and so we’ve provided many delay line effects to
allow maximum conservation of this precious resource. Use only the longest delay you
actually need.
Tip: Saving a session
“defragments” the effect/
DSP resources. If you have
used all your effects and
need another, try saving
the session.
The chart below shows three possible effects combinations. These were created by
using up the reverb resources first. Even more simultaneous effects are possible if fewer
reverbs and shorter delays are used.

Auto-Wah
This effect creates the sound of a guitar wah-wah pedal. The “Wah” filter sweep is
automatically triggered from the amplitude envelope of the input sound. Auto-wah
works well with percussive sounds such as guitar or bass.
The Auto-Wah is a bandpass filter whose frequency can be swept up or down by an
envelope follower, which extracts the volume contour of the input signal. The
Envelope Sensitivity setting allows you to properly set up the envelope follower to
receive a wide variety of input signals. This “envelope”, or volume contour, controls the
frequency of the bandpass filter so that it sweeps up and down with each new note. The
Attack controls the rate of the note-on sweep. As the input sound fades away, the filter
sweeps back at a rate determined by the Release setting.
The wah direction allows the filter to be swept either up or down in frequency. Use a
higher Center Frequency setting when the wah direction is down.

Chorus
An audio delay in the range of 15-20 milliseconds is too short to be an echo, but is
perceived by the ear as a distinctly separate sound. If we now vary the delay time in this
range, an effect called chorus is created, which gives the illusion of multiple sound
sources. A slight amount of feedback serves to increase the effect. A very slow LFO rate
is usually best for a realistic effect, but a faster LFO rate can also be useful with minimal
LFO depth (.2). Since this is a stereo chorus, an LFO phase parameter is included which
can be used to widen the stereo image.
ParameterDescription
DelaySets the length of the delay. Range: 0ms to 20ms.

Compressor
In its simplest form, an audio compressor is just an automatic gain control. When the
volume gets too loud, the compressor automatically turns it down. Compressors are
useful in musical applications because they allow you to record a “hotter”
without overloading the recording device.
Since the compressor turns down the gain of the signal, you might wonder how can it
make the signal level stronger. A Post Gain control allows you to boost the output gain
of the compressor in order to make up for the gain reduction. The overall level is higher
and only turned down when the signal level gets too loud. This level is called the
Threshold, which just happens to be the most important control on the compressor.

Basic Controls
The three main controls of a compressor are the Ratio control, the Threshold control and
the Gain control.
If the signal falls below the Threshold, no processing will take place. Signals exceeding
the Threshold will have gain reduction applied as set by the ratio control. This
important control allows you to dial in the range of amplitudes you want to tame. For
example, if you’re trying to trim off just the loudest peaks, set the threshold so the gain
reduction meter only shows compression during these peaks. One of the biggest
mistakes in using a compressor is having the threshold set too low. This adds noise as
the compressor will always be reducing the volume.
Attack
Release
Post Gain
The Ratio control determines how strongly the compressor will affect the signal. The
higher the ratio, the more reduction will be applied. If the ratio is high enough, (above 10:1 ) the signal will effectively be prevented from getting any louder. In this situation,
the compressor will be acting as a Limiter, placing an upper limit on the signal level. In
general, ratios from 2:1 to 6:1 are considered compression and higher ratios above
10:1 are considered limiting.
The Post Gain control amplifies the signal after it has been compressed to bring it back
up in volume. If you don’t increase the gain, the compressed signal will be much lower
in volume.
Two other important controls are Attack and Release. Attack controls how quickly the
gain is turned down after the signal exceeds the threshold. Release controls how fast
the gain is returned to its normal setting after the signal has fallen below the threshold

again. An attack setting of about 10 milliseconds will delay the onset of compression
long enough to preserve the attack transients in guitar, bass or drums while allowing
the sustain portion of the sound to be compressed. Longer release times are generally
used to reduce the so called “pumping” effect as the compressor turns on and off.
Don’t make the release time too long, however, or the compressor won’t have time to
recover for the next pluck or hit. In general, the attack and release controls are used to
smooth out the action of the compressor, but they can also be used to create special
effects.
The Pre-Delay parameter lets the level detector “look into the future” up to 4 milliseconds in order to anticipate upcoming peaks in the signal. This is accomplished of
course, by inserting delay into the signal path. This lookahead technique allows the use
of slower attack times without missing signal peaks. This parameter is especially
effective on drums and percussion.
The Input Meter allows you to monitor the strength of your input signal. Always try to
boost the signal before the compressor if you can.
The Compression Meter shows the amount of gain reduction being applied. Since this
meter displays how much the gain is being turned down, the meter moves from right to
left, instead of left to right like a normal meter.

Distortion
Most audio processors aim to provide low distortion, but not this one! The sole
purpose of this effect is to add distortion, and lots of it. This effect provides “fuzz box”
style, clipping distortion which is particularly effective on guitar, bass, organs, electric
pianos or whatever.
The input signal first passes through a lowpass filter. The Lowpass Filter Cutoff
Frequency allows you to control the number of new harmonics that will be generated
by the distortion element. The distortion element has an Edge control which controls
“how much” distortion will be added. A bandpass filter follows the distortion
generator. The EQ Center control lets you select a particular band of frequencies to be
output. The EQ Bandwidth controls the width of the center frequency band. Finally, a
gain control allows you to make up for any gain loss through the effect.
Use the Wet/Dry mix control in conjunction with the Edge control to reduce the
amount of distortion, or go wild and turn everything to 11!

Flanger
t
A flanger is a very short delay line whose output is mixed back together with the
original sound. Mixing the original and delayed signals results in multiple frequency
cancellations known as a comb filter. Since the flanger is a type of filter, it works best
with harmonically rich sounds.
A low frequency oscillator is included to slowly change the delay time. This creates a
rich, sweeping effect as the notches move up and down across the frequency range. The
amount of feedback deepens the notches, intensifying the effect. You can invert the
feedback signal by choosing a negative feedback value. Inverting the feedback signal
creates peaks in the notch filter and deepens the effect.

Freq Shifter
This unusual effect is sometimes called “spectrum shifting” or “single sideband
modulation.” Frequency shifting shifts every frequency in the signal by a fixed number
of Hz which causes the harmonics to lose their normal relationship. The more
common pitch shifter, in contrast, preserves the harmonic relationships of the signal
and so is better suited to creating “musical” harmonies.
This isn’t to say that the frequency shifter can’t be used musically. Small intervals of
frequency shifting (1 Hz and below) can produce a wonderful, lush chorusing or
phasing effect. For bizarre frequency shifting effects, simply crank up the frequency
knob. Frequencies can be shifted up or down by any specified amount from .1 Hz to 24
kHz. You can also shift pitch up on one side and down on the other if you wish.

Leveling Amp
The first compressors developed in the 1950’s were based on a slow-acting optical gain
cells which were able to control the signal level in a very subtle and musical way. This
effect is a digital recreation of the leveling amps of yesteryear.
The leveling amp uses a large amount of “lookahead delay” to apply gentle gain
reduction. Because of this delay, the leveling amp is not suitable for applications which
require realtime monitoring of the signal. This smooth and gentle compressor is
designed to be used in situations where delay does not pose a problem, such as
mastering a mix or compressing prerecorded stereo material.
Post Gain is the only control on the leveling amp. This control is used to make up the
volume lost by the compression. The Compression Ratio is fixed at about 2.5:1. If a
large peak is detected, the effect will automatically increase the compression ratio to
keep the audio output controlled.
The gain reduction meter shows you how much gain reduction is being applied. Since
the gain reduction meter displays how much the gain is being turned down, the meter
moves from right to left, instead of left to right like most meters.
Post GainAmplifies the signal after it has been compressed to

Lite Reverb
Reverberation is a simulation of a natural space such as a room or hall. The Lite Reverb
algorithm is designed to simulate various rooms and reverberation plates while using
fewer DSP resources than the Stereo Reverb. Up to five Lite Reverbs can be used at
once.
Decay time defines the time it takes for the reflected sound from the room to decay or
die away. The diagram below shows a generalized reverberation envelope.
Early Reflections
After a short pre-delay period, the echoes from the closest walls or ceiling are heard.
These first echoes, or Early Reflections, vary greatly depending on the type of room.
Some time after the early reflection cluster ends, the actual Reverberation (a dense cloud
of complex wall reflections) begins and decays according to the time set by the Decay
Time parameter. The Reverberance parameter controls the density and smearing of
both the early reflections and the reverberation cloud.
High frequency energy tends to fade away first as a sound is dissipated in a room. The
High Frequency Decay Factor adjusts the time it takes for the high frequency energy to
die away and thus changes the characteristics of the room. Rooms with smooth, hard
surfaces are more reflective and have less high frequency damping. Rooms filled with
sound absorbing materials, such as curtains or people, have more high frequency
damping.
The Low Frequency Decay Factor parameter adjusts the time it takes for the low
frequencies to die away. This control adjusts the “boominess” of the room.

Mono Delays - 100, 250, 500, 750, 1500, 3000
t
A delay line makes a copy of the incoming audio, holds it in memory, then plays it
back after a predetermined time. The delay number refers to the maximum delay time
that can be produced by the delay line. The six lengths, from 100 ms to 3 seconds,
allow you to make the most efficient use of the effect memory resource.
Long delays produce echoes, short delays can be used for doubling or slapback effects.
Very short delays can be used to produce resonant flanging and comb filter effects or
create monotone robotic-sounding effects (Hint: use feedback). Stereo signals are
summed together before entering the Mono Delay.
There is also a feedback path to send the delayed audio back through the delay line.
When creating echo effects, the feedback controls how many echoes will be produced.
With short delays, the feedback control acts as a resonance control, increasing the
amount of comb filtering produced by the delay line. Comb filtering: See page 71.
A High Frequency Rolloff filter in the feedback path cuts some of the high frequency
energy each time the audio goes through the delay line. This simulates the natural
absorption of high frequencies in a room and can also be used to simulate tape-based
echo units.
The Wet/Dry mix controls how loud the echoes are in relation to the original signal.

which can be swept up and down in frequency with a low frequency oscillator (LFO).
This creates a swirly, ethereal sound with harmonically rich sound sources of a type of

Vocal Morpher
This unique effect allows you to select two vocal phonemes and morph between them
using an LFO. Phonemes are the consonants and vowels we use in articulating speech
sounds and these sounds are very distinctive and evocative. 30 different phonemes are
available and these can be shifted up or down in pitch for even more effects.
To use the Vocal Morpher, you just select Phoneme A and Phoneme B from the list of
thirty. Now the LFO automatically morphs back and forth between the two selected
phonemes, creating interesting vocal articulations. The rate of the LFO is adjustable
and you can select between Sine, Triangle or Sawtooth waveforms. The sine and
triangle waves fade smoothly. The sawtooth wave gradually fades, then jumps abruptly
back.
When the frequency of the A or B Phonemes is shifted up or down, entirely new effects
can be produced. These frequency controls can also be used to tune the phoneme

Gate
t
This stereo noise gate is useful both for background noise reduction applications and
also for special effects.
The gate uses an envelope follower and threshold detector to turn on its output when
the input signal is above the turn-on threshold, and shut down its output when the
signal falls below the shut-off threshold. When ”turned on” the Gate passes the input
signal through to the output at unity gain and when “shut off” the Gate silences the
output or attenuates it by an adjustable gain factor. While the Gate is a stereo effect, the
left and right signals are gated in unison, with the envelope follower defaulting to the
louder of the two signals.
In normal operating mode, Gate turn-on is nearly instantaneous when the input signal
exceeds the Threshold level, while Gate Release time is an adjustable parameter. The
effect of the fast turn-on can be enhanced by using an optional 1 millisecond
lookahead in the Gate's envelope detector.
Together with the Threshold setting, tuning the Release time parameter is very useful in
order to achieve the least-obtrusive, most natural-sounding gating effect, which is
highly dependent on the specific program material being processed.
The gate does not offer an adjustable wet/dry mix parameter but does supply a Bypass
switch for effectively removing the effect from the signal path.

Core Effects Descriptions
Parameters
Threshold
When the input signal rises above the level set by the Threshold parameter, the Gate is
triggered to turn on and go from its maximum gain reduction level up to 0dB gain. The
turn-on threshold is adjustable anywhere between -70dB and 0dB (below the PatchMix
nominal operating point of -12dBFS.)
One of the keys to the smooth operation of the Gate is that the input Threshold level
that turns on the Gate is always higher than the level that shuts off the gate. This means
that the input signal level must descend substantially below the Threshold in order
to turn off again.
This difference between turn-on and shut-off levels, or the hysteresis, is 10dB. That
means that if the Threshold is -30dB, the signal level must fall to -40dB before the Gate
will begin to shut off.
Release Time
This parameter controls the time, in milliseconds, that is required for the Gate to shut
off. More specifically, this is the time that will be required for the Gate control signal to
go from unity gain at 0dB down to the Max Gain Reduction level.
The optimum value for the Release time is dependent on the program material as well
as the effect you're trying to achieve. Optimum Release time is also highly dependent
upon the settings of the Threshold and Max Gain Reduction parameters.
In general, times less than about 10 msec are prone to cause clicks in the output, while
times longer than 30 msec may make the gating effect obvious if the background signal
being gated out is very noisy.
Max Gain Reduction
This parameter sets the attenuation that will be applied to the signal when the Gate is
shut off. The Gate control signal will swing between 0dB and this value as the Gate
turns on and shuts off.
To perform a strict “gating” operation, Max Gain Reduction would normally be set to infinity in order to completely silence the output of the Gate.
However, there are good reasons to set Max Gain Reduction to something less drastic
than infinite attenuation. Sometimes the silence between gated signals is “too quiet” especially when the signal represents a solo vocal or instrument, where the complete
lack of any sound between voiced segments sounds unnatural. For these applications,
setting Max Gain Reduction somewhere between -20dB and -40dB is more appropriate.
In tandem with a high Threshold, Max Gain Reduction can also be set to very modest
values like -5 or -10dB in order to add a subtle “punch” enhancement to transients.
This has an effect similar to an expander, where the attack transients which exceed the
Threshold stand out by 5 or 10dB above the normal signal (you can make up for that 5
or 10dB attenuation by using a trim pot or boosting the channel strip gain after the
Gate.)
Lookahead
By default, the Gate effect uses a fixed 1 millisecond lookahead to avoid clipping off
the leading edge of signal transients when the Gate turns on. However, this is actually
implemented by adding a 1 millisecond delay to the signal through the gate. For appli
cations where this additional 1 millisecond latency is a problem, the Lookahead can be
turned Off.

Level Meter
This meter represents the input signal level in dB, and is in fact the output of the Gate's
envelope follower. Since the envelope follower is driven by the greater of the left or
right channel, this monophonic meter represents the greater of the two input signals.
Gain Reduction Meter
This meter shows the value in dB of the gate control signal which is used to boost or
attenuate the input signal. Its most-rightward maximum value of 0dB represents a
unity gain path through the Gate in its turn-on state. Except for the possibility of the 1
millisecond lookahead latency, the Gate behaves exactly as a straight wire in this
turned-on state. Values less than 0dB represent the amount by which the input signal is
being attenuated as the Gate shuts off.
The most-leftward gain shutoff value achieved by the Gain meter is set by the Max Gain
Reduction parameter (values from -70dB to -infinity are off the meter.) The speed with
which the Gain signal decays from 0dB to the shutoff value can be observed to change
according to the Release time parameter.

Reshaper
The Reshaper effect is a special purpose dynamics modification program, designed to
“resculpt” the amplitude envelope of an audio signal. The effect uses an envelope
follower and threshold detector to drive an ADSR-type gain stage, which can impose
new attack, decay, sustain and release profiles on the signal's original envelope.
Applications
• “Punch” Reducer - slow turn-on with added lookahead trims attacks off signals
• “Punch” Enhancement - fast turn on with high thresholds and release gain
expands signal attack transients
• Auto Volume Pedal - long attack times with Attack Retrigger can automatically
simulate use of a guitar volume pedal for gently fading in each note.
• Ambience Reduction - can be used like a gate to suppress ambient reverberations that below a certain threshold.
When the input signal exceeds an adjustable Threshold, the Attack phase begins and
continues until the gain reaches unity (0dB). After the Attack peaks, the gain stage
immediately transitions into the Decay phase, which continues until the gain falls to
the Sustain level. During the Sustain phase, the gain stage holds a constant level until
the input signal passes below the Release Threshold. During the Release Phase, the gain
returns to the Release Level where it remains until the another input transient triggers
the next Attack phase.

Attack, Decay and Release times are all adjustable, and the shape of each of these
segments is selectable between exponential, linear, or logarithmic. An additional Hold
Time can be used to extend the Sustain phase past the point where the signal has
passed the Release Threshold.
If the Sustain Level is set the same as the Release Level, then the Reshaper effectively
becomes a two-phase “transient catcher” where the Release Threshold, Hold Time and
Release Time are ignored.
While the peak Attack gain level is always fully turned on, note that the Release Level is
not necessarily completely off, but can be adjusted upward so that the Reshaper retains
a nominal minimum gain. This allows the Reshaper to resculpt only the louder
transients of a signal while maintain a nominal output signal level the rest of the time.
The Release Threshold is always expressed relative to the Attack Threshold so that they
will automatically track each other when the Attack Threshold is adjusted.

Threshold parameter, Reshaper's ADSR engine begins the Attack
phase. The turn-on threshold is adjustable anywhere between
-40dB and 0dB (below the PatchMix nominal operating point of
-12dBFS.)
Attack TimeThis parameter controls the time, in milliseconds, that is required
during the Attack phase for the gain rise from its quiescent Release
Level to unity gain, or 0dB.
Decay TimeThis parameter controls the time, in milliseconds, that is required for
the gain to fall from 0dB down to the attenuated Sustain Level.
Note that if the Sustain Level is set to 0dB this decay time becomes
simply a delay before entering the Sustain phase.
Release TimeThis parameter controls the time, in milliseconds, that is required for
the gain to fall from the Sustain Level down to the Release Level.
Level MeterThis meter represents the input signal level in dB, and is in fact the
output of the Gate's envelope follower. Since the envelope follower
is driven by the greater of the left or right channel, this
monophonic meter represents the greater of the two input signals.
Sustain LevelThis sets the gain level applied to the input signal when the ADSR
engine is in the Sustain phase.
Release LevelThis sets the final gain level applied to the input signal when the
Release phase is fully decayed. When set to the minimum (-70dB)
the effective Release Level is -infinity, i.e., fully turned-off.
Hold TimeThis parameter allows additional time to be added onto the Sustain
phase after the input signal falls below the Release Threshold before
transitioning to the Release phase. This extension of the Sustain
phase is useful for altering the tail dynamics of the sound.

ParameterDescription
Attack
Lookahead/
Delay
This parameter is adjustable in milliseconds to allow the Reshaper to
either “look ahead” and advance (negative values) or “delay”
(positive values) the response of the envelope detector relative to
the dynamics of the input signal.
For example, negative lookahead values can cause the envelope
detector to start the ADSR's Attack phase before the actual attack of
the signal so as not to miss any audible transients. Likewise, positive
delay values can be used to start the Attack “late”, so that signal
transients are intentionally missed by the Attack.
Release
Threshold
Attack
Retrigger
This parameter controls the level in dB below the Attack Threshold
at which the Release phase of the ADSR will begin.
By default, when the value of this parameter is Disabled, the
Reshaper's ADSR engine will wait until at least the Release phase of
a cycle before restarting a new Attack phase.
By setting Attack Retrigger to Enabled, however, the Reshaper
becomes sensitive to new input signal transients during any phase
of the ADSR cycle. In addition, enabling this parameter will also
cause the attack to restart at the Release Level instead of whatever
gain was being applied when the new attack arrived.
Attack CurveThis parameter allows the gain during the Attack phase to follow
one of 3 curves: linear, logarithmic, or exponential. Because the
ADSR computes gain using linear coefficients, the exponential curve
comes the closest to being a “constant in dB” gain ramp. A linear
curve provides a somewhat more immediate turn-on, while the
logarithmic curve presents a very abrupt turn-on.
Release CurveThis parameter selects gain curves exactly as for the Attack Curve
parameter, except that the selected curves apply to both the Decay
and Release phases of the ADSR.

Multimode EQ
The Multimode EQ is a flexible stereo filter that is capable of implementing a range of
powerful filter topologies. It is useful both for utility EQ applications and also for
special effects.
The Multimode EQ is built from an array of filter sections that can be configured to
support:
• Lowpass filters with up to 48dB/octave rolloff
• Highpass filters with up to 48dB/octave rolloff
• Highpass + Lowpass series or parallel combination with up to
24dB/octave rolloff
• Bandpass filters with up to 24dB/octave rolloff
• Bandcut filters with up to 24dB/octave rolloff
In addition to cutoff or center frequency parameters, each of the above filter types also
has a switchable rolloff rate and adjustable resonance.
A Filter Edit parameter controls whether the Multimode EQ operates in Stereo, where
filter parameters are adjusted identically for both channels, or split Left and Right,
where the left and right channels support completely independent filter types and
parameter values.
5 - Effects
Core Effects Descriptions
In addition to a standard Bypass switch, the effect offers an adjustable wet/dry mix
parameter. While not normally found on EQ sections, adjustable wet/dry mixtures can
be useful for generating phase cancellation and other special effects.
Applications
• Basic Tone Control - for fidelity enhancement
• Rumble Filter - use the highpass configuration with 48dB/octave rolloff below
50Hz.
• Subwoofer Support - use the lowpass configuration with 48dB/octave rolloff
below 100Hz.
• Extreme Spectral Shaping - use Highpass+Lowpass, Bandpass or Bandcut with
independent hi/lo resonance
• Pseudo-stereo Effect - apply slightly different EQ to left and right channels to
broaden the spread of a mono signal
• Cross-over - left and right channels split a mono signal between highpass and
lowpass with a sharp transition region.

Parameters
While the Multimode EQ has many parameters applicable to the various possible
configurations of channels and filters, it selectively enables or hides parameters
depending on their applicability to the current configuration. As a result, not all of the
parameters listed below appear on-screen at the same time.
ParameterDescription
Filter EditThis parameter controls whether the filter editing parameters apply
to both left and right channels in tandem (Stereo), only to the left
channel (Left) or only to the right channel (Right).
Filter ModeThis parameter selects one of 5 different filter types: Lowpass,
Highpass, Lowpass+Highpass, Band Pass or Band Cut.
Lowpass
The frequency response of the lowpass filter looks something like the diagram below:
In this mode, the Lowpass filter can have up to a 48dB/octave rolloff slope. In this
mode the Lowpass Rolloff, Lowpass Frequency and Lowpass Resonance parameters are
available for editing the filter response.
Highpass
The frequency response of the highpass filter looks something like the diagram below:
In this mode, the Highpass filter can have up to a 48dB/octave rolloff slope. The
Highpass Rolloff, Highpass Frequency and Highpass Resonance parameters are
available for editing the filter response.
88Creative Professional
Page 89
Highpass -> Lowpass
In this mode, the Lowpass and Highpass filters are connected in series and both sets of
Lowpass and Highpass parameters are exposed and independently editable to create
the overall filter response. The maximum rolloff slope of each filter is limited to 24dB/
octave in this mode.
In Highpass -> Lowpass mode, the effect does not place any limitations on the
Frequency parameters of one filter relative to the other. In normal use, the Highpass
Freq parameter will be less than the Lowpass Freq parameter, creating a bandpass-type
response:
However, if the Highpass Freq parameter is greater than the Lowpass Frequency
parameter, the passband effectively disappears, since the part of the spectrum which is
above the highpass and below the lowpass is non-existent. As a result, you'll hear a
rapidly attenuating bandpass response as the corner frequencies diverge.
5 - Effects
Core Effects Descriptions
Note that while the Highpass -> Lowpass combination appears the same as the Band
Pass filter, this mode is different in several important respects:
• The rolloff points are independently adjustable as individual frequencies rather
than specified as a combination of center frequency and bandwidth.
• The rolloff slope of each High and Low filter can be specified separately while
the Bandpass and Band Cut filters use the same slope.
• The Resonance of each High and Low filter can be specified separately while the
Bandpass filter uses the same Resonance at high and low corner frequencies.
Highpass || Lowpass
In this mode, the Lowpass and Highpass filters are connected either in parallel, and
both sets of Lowpass and Highpass parameters are exposed and independently editable
to create the overall filter response. The maximum rolloff slope of each filter is limited
to 24dB/octave in this mode.
In Highpass || Lowpass mode, the effect does not place any limitations on the Freq
parameters of one filter relative to the other. In normal use, the Highpass Freq
parameter will be higher than the Lowpass Freq parameter, creating a bandcut-type
response:
E-MU PCIe Digital Audio Systems89
Page 90
5 - Effects
Core Effects Descriptions
However, when the Highpass Freq parameter is lower than the Lowpass Freq
parameter, the combined filter response is basically flat, since the passbands of each
filter combine to admit the entire spectrum. An exception occurs when there is
resonance added to the filters - you'll hear the resonant peaks as increased gain above
the otherwise flat spectral response.
Note that while the Highpass || Lowpass combination appears the same as the Band
Cut filter, this mode is different in several important respects:
• The rolloff points are independently adjustable as individual frequencies rather
than specified as a combination of center frequency and bandwidth.
• The rolloff slope of each High and Low filter can be specified separately while
each side of the Band Cut filter uses the same slope.
• The Resonance of each High and Low filter can be specified separately while the
Band Cut filter uses the same Resonance at high and low corner frequencies.
Band Pass
In this mode, the Lowpass and Highpass filters are connected in series to form a
bandpass filter, whose Center Freq and Bandwidth parameters are used to generate the
rolloff frequencies for the underlying Lowpass and Highpass filters. In this mode the
rolloff slope on the high and low sides of the passband is symmetrical and is limited to
a maximum of 24dB/octave. The Resonance is also common to both filter sections .

Note that the effect is split between a signal path and a sidechain path that contains the

Compressor is very close to a “straight wire”, with only a delay line and one gain
control element inserted in it. The sidechain contains the bulk of the compressor
algorithm and is responsible for computing the gain control signal. Signal multiplexers
at the front of the signal path and sidechain allow linked stereo compression or split
signal path/sidechain processing.
The RFX Compressor does not have the input gain control that is found on some
compressors. These are typically used to align the input signal range to the
compression threshold. Instead, we've allowed the RFX Compressor's Threshold

parameter to operate over an exceptionally large range of 0-60dB so that it can be
“steered” to the appropriate range of the input signal. The output Gain parameter also
operates - either manually or automatically - over the unusually large range of -60dB to
+60dB in order to renormalize the compressor's output for the next stage of the signal
path.
The wide dynamic range of the RFX Compressor aside, it's generally a good idea to
maintain the hottest signal levels possible without clipping at the input to any audio
processor.
Parameters
Threshold
Threshold sets the input signal level above which dynamic range compression takes
place. Everything above the threshold will be brought down in volume. The
compression threshold ranges from -0 to -60dB, relative to full scale (0dBFS) input.
Setting the Threshold to 0dB disables normal compression, since no signal can exceed
the maximum possible input level. A Threshold setting of 0dB is still useful, however,
when using soft-knee compression or gating, since these actions occur below (and their
thresholds are set relative to) the Threshold parameter.
Gain Reduction Meter
As input signals exceed the Threshold, the rightness character in the bargraph is lit, and
successive characters are lit for each approximately 3dB in gain reduction imposed by
the compressor on the input signal. Because this is a compression meter and not a level
meter, the same input signal level will show widely varying meter readings depending
on the setting of the Ratio parameter.
Ratio
Sets the ratio of output signal to input
signal levels, selectable in 16 steps
from 1:1.1 to 1:INFINITY.
When Neg Compression is set to
Enabled, the range of compression
ratios extends beyond INFINITY to
encompass negative compression
ratios from 1:-100 down to 1:-1,
which can be useful for applications
like ducking and other special effects.

Attack
Sets the amount of time that the compressor's level detector will take to respond to an
increase in signal level. The Attack range is adjustable from Instantaneous (essentially a
peak detector that follows individual samples) to 10 seconds (useful for long-term
leveling or automatic mixing applications.)
Tip: A ratio of Infinity:1
combined with high
threshold and fast attack/
release results in an
effective peak limiter.
Release
Sets the amount of time that the compressor's level detector will take to respond to a
decrease in signal level. The fastest Release time is 100 microseconds, useful for some
special effects but highly prone to distortion; more typical release times are in the range
of 70 milliseconds to 1 second. Release times up to 10 seconds are available for longterm leveling or automatic mixing applications.
92Creative Professional
Page 93
When the Auto-release parameter is in its signal-dependent settings, the Release time
shown represents the shortest possible release time. In Auto-release modes the
displayed Release time will be automatically extended depending on the dynamics of
the input signal.
Gain
Sets the compressor's output gain in dB, from +60dB boost to-60dB cut. This control
follows all of the other elements in the compressor's signal path, so positive gain boost
can be used to make up for the gain reduction normally applied to signals above the
compression threshold. Alternatively, negative gain cut can be used to make up for the
gain increase that is applied to signals below the threshold in Soft Knee mode.
Auto Makeup Mode: When adjusted downward past the -60dB cut, the Gain
parameter begins operating in Auto Makeup mode. Auto Makeup mode is used to
compensate for the drop in output level normally resulting from the gain reduction
actions of the Threshold and Ratio parameters. Auto Makeup makes it much easier to
adjust these parameters since there is no need to switch back and forth to the Gain
parameter in order to perform the gain compensation manually.
Auto Makeup looks at the gain reduction implied by the setting of the Threshold and
Ratio parameters and automatically applies a complementary gain increase so that an
ideal 0dB input signal results in a 0dB - or lower - output signal. In this mode, indicated
by the Threshold legend,
the Gain parameter adjusts the output level
from that 0dB input signal to fall anywhere in the range of 0dB down to -60dB.
Advanced Parameters
This parameter controls whether the “Advanced Parameters” listed in this section are
hidden or exposed on the screen. For simple applications, quick edits or for novice
users, these advanced parameters can be hidden to minimize screen clutter and
preclude erroneous operation. For special and exotic applications and for experienced
users, these parameters can be exposed to allow access to all the gory details of the
compressor's operation.
Note that even when this parameter is set to “Off”, the settings of the advanced parameters are still active; the only effect of this parameter is to hide them from the screen.

Soft Knee
This parameter sets the depth of the compression transition region, giving an
adjustable hard or soft “knee” to the compressor's gain curve. Setting the depth of this
region results in a knee shape that can be varied from a sharp transition to one that is
imperceptibly gradual.
With the default value of Off, the Soft Knee parameter causes the gain curve to switch
immediately at the Threshold point from no compression (1:1) to full compression
(1:Ratio), representing the hard knee effect. By adjusting the parameter value, an
additional knee threshold can be created 1dB to 60dB below the regular compression
Threshold. Between these two thresholds the effective compression ratio increases
smoothly along the curve of a circular arc, from 1:1 at the lower knee threshold to the
full compression of 1:Ratio at the upper Threshold. Both the Soft Knee depth and the
Ratio will affect the particular shape of the knee: shallower depths and higher Ratios
will create a sharper knee, while greater depths and lower ratios create a softer knee.

This diagram shows the effect of varying the Compression Ratio with a

the compression ratio over the Soft Knee Threshold area. The upward arrow
shows the additional gain added to signals below the Threshold.
In the region between the lower knee and upper Threshold, a variable amount of gain
reduction is applied depending on the signal level and Ratio setting. To keep this gain
reduction from “dragging down” the signal levels at the Threshold point, a comple
mentary gain boost is automatically applied to all signal levels below the Threshold
when the Soft Knee is enabled. This gain increase with depth and Ratio is illustrated by
the upward arrows in the diagrams, and is similar to the action of the Auto Makeup
Gain parameter. Thus signal levels below the Threshold increase as the Soft Knee depth
and/or Ratio is increased (but see the Gate parameter, below.)

Gate
This parameter enables automatic gain reduction on signals that fall from 1 to 120dB
below the Threshold point (or Soft Knee threshold, if enabled.) This can act effectively
as a “noise gate” on low-level signals that have been boosted by the action of the Gain
or Soft Knee parameters. The gating action follows a somewhat soft-kneed contour of
its own so that turn-on and turn-off at the gate threshold is not too abrupt.

In this example, the Gain has been boosted by +15dB. The Gate cancels out the +15dB Gain
boost below the Gate Threshold. Signal levels above the Gate Threshold will be boosted; signal
levels below this point will not be boosted and will be 15dB lower in volume.
Note that, strictly speaking, the term “gate” is a misnomer in this context, since the
action of this parameter is simply to cancel out gain increases that resulted from the
settings of other parameters. This can be seen by the arrows in the diagram as the gain
is reduced below the Gate threshold back down to the dotted line representing unity
gain. The result is that if the Gain parameter is set negative or the Soft Knee parameter
is disabled, the Gate parameter will have no effect.
Comp Lookahead/Delay
This parameter controls compressor
lookahead or delay by setting the
relative time offset, in milliseconds,
between the compressor's signal path
and its sidechain path.
At negative values, this parameter lets
the level detector in the compressor's
sidechain “look into the future” up to
100 milliseconds in order to antic
ipate upcoming peaks in the signal accomplished of course, by inserting
delay into the signal path. This
lookahead technique allows the use
of slower attack times without
missing signal peaks.
At positive values, the signal path delay is zero; instead, a delay of up to 50 milliseconds is inserted into the sidechain path containing the level detector. This delay can
be used intentionally to cause the compressor to miss signal peaks, retaining the

“punch” and “bite” of signal attacks while subsequently compressing the sustained
portions of the sound.
In general, both positive and negative values of this parameter are useful for applications where the normal envelope of a signal is being creatively manipulated to achieve
special effects.
Auto-Release
This parameter causes the effective Release time to be extended automatically based on
the dynamics of the input signal. This parameter emulates the program-dependent
release characteristics found on some classic analog compressor/limiters.
When not set “Off”, the Auto-release parameter treats the Release parameter value as a
minimum release time, extending it by as much as a factor of 10 depending on
different, selectable characteristics of the input signal:
In Program-dependent mode, release times are increased depending on how often,
how long and by how much the input signal (“program material”) exceeds the
Threshold. Release times increase slowly under sustained excursions of the input over
the Threshold, and typically return back to normal within a few seconds after the signal
level has fallen below it. This emulates the signal “memory effect” exhibited by some
electro-optical compressors.
In Compression-dependent mode, the release extension characteristics are similar, but
in addition depend on the amount of gain reduction being applied to the signal. Thus
the same signal will cause more release-time extension at higher compression Ratio
settings than at lower ones.

UNLIMITED.

This feature emulates the phenomenon of the compression “tail” found in the gain
curves of some classic analog compressor/limiters. The phenomenon results from the
inability of these devices to apply more than a certain amount of compression to the
input signal. When the device “runs out” of enough gain reduction to compress a very
high level signal, it resumes a 1:1 gain curve again. This “deficiency” has the
unexpected sonic benefit of restoring some dynamics to the compressed signal - but
only on the highest input peaks - thus adding some “life” back into otherwise overcompressed signals.
Unlike analog compressors, the Max Compression parameter allows you to adjust the
amount of gain reduction before the compressor returns to a 1:1 gain curve. The
diagram shows three settings of the Max Compression parameter; the compressor
“gives up” and returns to 1:1 after 6, 15 and 24dB of compression have been
exhausted, respectively.
The parameter is most useful at higher compression ratios, allowing the gain curve to
be carefully tailored to the dynamics of the signal as well as the Threshold and Ratio
parameters. The limit set by the Max Compression parameter does not apply to gain
reduction performed in the Soft Knee region of the gain curve.
Max. Comp. = 24dB
Note: You may need
to use the Gain parameter
to keep these restored
peaks from clipping the
compressor output since
Auto Makeup gain doesn't
automatically take the
compressor tail into
account.
Neg Compression
When the Neg Compression
parameter is Enabled, the range
of compression values available
to the Ratio parameter extends
beyond INFINITE to encompass
negative compression ratios from
1:-100 down to 1:-1. Using
negative compression ratios
results in an output signal that
actually gets quieter as the input
signal rises above the threshold.
This action can be useful for
applications like ducking and for
other special effects.

The diagram above shows the gain curves using a Threshold at -30dB and a range of
negative compression ratios.
At just past 1:INFINITE, the setting of 1:-100 causes input signals approaching 0dB to
be only slightly decreased below -30dB. In contrast, the compression ratio of 1:-1
causes a 2dB gain reduction for each 1dB of additional input signal level, resulting in
an output signal level that is folded down over the Threshold.
Create a Ducker
To create a ducker, in which a background signal's level is reduced in the presence of a
foreground signal, first set the Input Mode parameter to L In/R Sidechain. Then send
feeds from the background signal to the left input, and from the foreground signal to
the right side input. Set the Ratio parameter to -1:1 (or lower for less background
reduction), and dial in a low Threshold such as -50, so any foreground signal above 50dB will cause gain reduction in the background signal. This technique works best
with slow Attack and Release times — use a liberal amount of Compression Lookahead
to keep the background from masking the beginning of foreground sounds.

Input Mode
The Input Mode parameter allows the compressor signal path and sidechain to be
driven in common or by separate inputs. This is a feature of many compressors and is
useful for a range of applications and special effects.
By default, the Input Mode of the compressor is Stereo. In this mode the two
independent left and right signal paths are gain controlled by a parallel sidechain path
common to both inputs that contains the compressor's level detector. This single level
detector works on the higher of the two input signal levels, so that signal peaks are
properly compressed and no L/R image shift results from compression operations.
When the Input Mode is set to L In/R Sidechain, the signal path is fed exclusively from
the left channel and the sidechain is fed exclusively from the right channel. This allows
dynamics control between two completely independent signals. In this mode both the
compressor's left and right outputs are fed by the mono signal from the left input
channel's signal path.
Splitting the signal path and sidechain makes possible applications where the two
signals may be completely unrelated, such as ducking. Other split-sidechain applica
tions result from situations where a stereo input signal has had different processing
applied between left and right channels. One example would be to place a stereo
equalizer ahead of the compressor in order to implement a version of de-essing or
“de-booming.” See page 101.
