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.

2 - Installation 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 0202 Daughter Card

The 0202 Daughter card is the companion card for E-MU 1010 systems which don’t include the MicroDock. The 0202 Daughter card provides one pair of 24-bit balanced analog inputs and one pair of 24-bit balanced analog outputs, plus MIDI in and out.

Connections

Analog Inputs and Outputs
The 0202 Daughter Card provides two balanced, analog inputs and two balanced, line level analog outputs. The inputs can be connected to any line level

Line Outputs
mixing board, the auxiliary input on your stereo or a set of powered speakers. The line outputs are NOT designed to drive headphones directly. Connect the line outputs to a stereo receiver or mixer with a headphone jack to obtain the proper current drive.
MIDI
In/Out
Either TRS (tip-ring-sleeve) 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”
.
MIDI In/Out
The MIDI input and output port can be assigned in your specific MIDI application. Connect the MIDI adapter cable that came with your 0202 Daughter card to the mini­DIN connectors on the card. The adapter cables convert the mini-DIN to standard DIN connectors used on most keyboards and synthesizers. Connect MIDI Out to the MIDI In port of your synthesizer and MIDI Out of your synth to MIDI In of the 0202 Daughter Card.

The MicroDock
The MicroDock is completely “hot pluggable”— It’s OK to plug or unplug the MicroDock while the computer is turned on.
It’s a good idea to mute MicroDock inputs 2 in the PatchMix DSP mixer when nothing is plugged in, since the turntable preamp has a very high gain (60dB) and could contribute extra noise to your mix/monitor bus.
The inputs are configured as follows:
(2) mono microphone/line inputs (2 inputs)
(2) stereo pairs of line level inputs (4 inputs)
(1) stereo pair of S/PDIF/AES digital inputs (2 inputs)
(4) stereo pairs of ADAT channels on the ADAT optical input (8 inputs)
(1) RIAA equalized turntable preamp input allows you to connect a turntable
without using an expensive external preamp. Note: These inputs are automati cally disconnected when plugs are inserted into inputs 2L & 2R.
(2) MIDI input ports using the supplied breakout cable
The outputs are configured as:
(3) Stereo pairs of line level outputs
(1) Stereo pair driving a stereo headphone jack (Share the same routing as Line
Outs 1L/1R)
(1) Stereo pair of S/PDIF/AES digital outputs
(4) Stereo pairs of ADAT channels on the ADAT optical output
-
(3) Stereo 1/8” computer speaker outputs. These outputs carry the same signals as
the 3 stereo line level outputs and are provided as a convenience for connecting computer or powered speaker systems.

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 source.
S/PDIF digital I/O can be used for the reception and/ or transmission of digital data from external digital devices such as a DAT, external analog-to-digital converter or an external signal processor equipped with digital inputs and outputs.
The S/PDIF out can be configured in either Professional or Consumer mode in the Session Settings menu. The MicroDock can also send and receive AES/EBU digital audio through the use of a cable adapter. See “Cables - balanced or unbalanced?” details.
See “System Settings”.

Important: When
using any type of digital I/O such as S/PDIF or ADAT, you MUST sample sync the two devices or clicks and pops in the audio will result.
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.

Line Level Analog Inputs
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.

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.

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.

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 Rate Selects 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.)
The chart below shows how to connect the outputs for 5.1 surround sound playback.

Insert Section

The Insert Section is next in line. PatchMix DSP effects can be selected from the Effects Palette and dropped into the insert locations. 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 want in the mix (as shown in the Mixer Overview on and B are routed to Aux Send 1, which has a HOST ASIO SEND insert to the recording application.

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 Color Indicates
Red Indicates signal clipping.
Yellow Good strong signal level.
Green Signal 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.
42 Creative 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 Systems 43
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.

Test Signal Output Level
The Sine Wave Oscillator frequency is variable from 20Hz-20kHz. The level is variable from off to +30dB.
White Noise is a mixture of all frequencies in the audio spectrum at the same average level (analogous to white light in the visible spectrum).
Pink Noise provides equal power distribution per octave. (White noise has more power in the higher octaves.) Pink noise and white noise are both useful as wideband 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.
1. Right-Click over the Insert section in question. A pop-up dialog box appears.
2. Select Insert Test Tone/Signal Generator from the list of options. A Test Tone
insert appears in the insert location.
3. Click on the Test Tone insert to view and adjust the controls in the TV screen.
4. To move the Test Tone to another location, simply drag and drop it into the
desired position.

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.

The Aux 1 & 2 buses can also be used as additional submix output buses just like the main output. Simply drop an ASIO or External Send Insert into the chain and the stereo bus is sent. Turn off the Return Amount if you don’t want the submix to be combined into the main mix.
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 or Post Fader Aux Sends
When you create a New Mixer Strip you have the option to place both Aux Sends after the channel volume fader and mute control or you can place them before the fader and mute. Post-Fader turns down the send level as you lower the volume of the strip. With 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 Level Fader and Mute settings. The Pre-Fader setting allows you to create two completely different mixes using the Aux Buses since the signal levels of this mix won’t be affected by the fader settings.

and Aux Sends in the signal flow. On stereo strips 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 expect—press the button and the sound from that channel is cut off. Pressing the Solo button while the Mute button is pressed allows you to hear the channel until solo is turned off.
The Solo button allows you to listen to only that channel while muting the rest of the inputs. If 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”, “drums” and so on.

The main section contains all controls for controlling the main mix elements as well as a “TV screen” for viewing the input/output routing or parameters of the selected insert.
The three buttons across the top of the main section select what is shown on the TV display. Input and output routings are graphically displayed. When an insert is selected (by clicking on the insert), the screen shows the available parameters for the currently selected insert.
Below the TV screen is the Aux Bus section where effects, effects chains or other inserts can be assigned to the two aux buses. Send and return levels can be individually controlled for each of the two Aux Buses.
The Aux 1 and Aux 2 buses are fed by the two Aux Sends on each mixer strip. The Master Send Level control on Aux bus 1 and 2 can be used to attenuate or boost the signal going into the Auxiliary Inserts. There is also a Master Return Level to control the amount of the effected signal that will be returned into the main mix.
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 is a stereo peak meter that indicates the signal strength for the main mix.
The Monitor section has a volume, balance, and a mute control to cut off the monitor output.

Auxiliary Effects & Returns

The section immediately below the TV Screen is where you assign the Auxiliary Effects. In a traditional mixing console, auxiliary effects 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. Effects such as EQ and compressors are usually NOT used as sidechain effects because they can cause unpredictable results when returned to the main bus.

Sync/Sample Rate Indicators

The Sync/Sample rate Indicators show the current session’s sample rate and whether it is internal or slaving to an external source. The display indicates which sample rate is currently in effect. If an external source is being used, the Source display reads “EXTERNAL.”
When slaving to an external master source, the clock may drift slightly or change dramatically (i.e. abrupt sample rate change or unplugging of physical master source). PatchMix DSP is tolerant to minor drifting within the supported rates of 44.1k, 48k, 88.2k, 96k,
176.4k and 192k, but if the sample rate drifts out of this 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 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.
“DSP Resource Usage” on page 62.
Saving a session “defragments” the effect/ DSP resources. If you have used all your effects and need another, try saving the session.

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.
Parameter Description

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.

Level

Ratio
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 Gain Amplifies the signal after it has been compressed to
bring up the volume. Range 0dB to 36dB

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.

Phase Shifter

A phase shifter produces a fixed number of peaks and notches in the audio spectrum 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 pitch shift with simpler sounds. The phase shifter was invented in the 1970’s and the characteristic sound of this device evokes emotions of that musical era.
By setting the LFO Depth to zero and tuning the LFO Center, a fixed multi-notch filter is created.

The Rotary incorporates acceleration and deceleration as you switch between the two speeds.

Stereo Delays - 100, 250, 500, 750, 1500

The Stereo Delays are true stereo delay lines in that the left and right channels are kept entirely separate from each other. The delay number refers to the maximum delay time that can be produced by the delay lines. The five different lengths, from 100 ms to 1.5 seconds, allow you to make the most efficient use of the effect memory resource.
Because the left and right channels can have different delay times, you can create a panning effect by setting one delay long and the other short. Very short delay times combined with a high feedback amount can be used to create monotone robotic­sounding effects. Using the longer stereo delays, you can “overdub” musical lines one on top of the other with the feedback control turned up.

Stereo Reverb
Reverberation is a simulation of a natural space such as a room or hall. The stereo reverb algorithm is designed to simulate various halls, rooms and reverberation plates.
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.

Core Effects Descriptions
Time
Early Reflections
Late Reverb
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 (late reverb delay), the late reverber­ation (a dense cloud of complex wall reflections) begins and decays according to the time set by the Decay Time parameter.
Diffusion is the amount of scattering and density of the late reverberation cloud. Rooms with many complex surfaces have more diffusion than bare rooms.
High frequency energy tends to fade away first as a sound is dissipated in a room. The High Frequency Damping parameter 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 Damping parameter adjusts the time it takes for the low frequencies to die away. This control adjusts the “boominess” of the room.

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 frequencies to the range of audio you are processing.

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.

5 - Effects 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.
Parameter Description
5 - Effects
Core Effects Descriptions
Attack Threshold
When the input signal rises above the level set by the Attack 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 Time This 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 Time This 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 Time This parameter controls the time, in milliseconds, that is required for
the gain to fall from the Sustain Level down to the Release Level.
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.
Sustain Level This sets the gain level applied to the input signal when the ADSR
engine is in the Sustain phase.
Release Level This 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 Time This 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.
E-MU PCIe Digital Audio Systems 85
Page 86
5 - Effects Core Effects Descriptions
Parameter Description
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 Curve This 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 Curve This 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.

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.
Lo-Fi Effect (telephone, walkie-talkie, guitar mini-amp, distance simulation)
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.
Parameter Description
Filter Edit This 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 Mode This 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.
88 Creative 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 Systems 89
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 .

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.

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. See the discussion of the Neg Compression parameter on
page 97.

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.
92 Creative 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.

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.)
Tip: Setting a high Ratio with the Threshold at 0dB and the Soft Knee at ­60dB creates a compressor whose ratio varies smoothly from gentle compression at lower signal levels to peak limiting at maximum signal level

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.

Max Compression
This parameter is used to limit the amount of gain reduction that the compressor can apply. The limit is set as a maximum number of dB of gain reduction, from 3dB to 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.
