About Phantom Power
Dynamic microphones (such as a Shure SM57) do not require phantom power, but are not harmed by it. Most condenser microphones (like an AKG C3000) do require phantom power to operate.
Although phantom power is safe for most microphones, it is possible to damage some ribbon mics with it. Always turn off phan­tom power and wait at least ten seconds be­fore connecting or disconnecting a ribbon microphone.
If you are not sure about the phantom power re­quirements for your microphone, consult your microphone’s documentation or contact the manufacturer.
Eleven Rack User Guide8
Control Knobs
Output To Amp 1 (L)
Use the Control knobs to access amp and effects controls, as well as other settings throughout Eleven Rack. The controls are pre-assigned, de­pending on the current mode. The knobs light up in different colors, depending on their state:
Amber The current knob is assigned to an amp, cab, or FX loop parameter.
Green The current knob is assigned to an effects parameter.
Red The current knob is positioned differently than the assigned control’s saved position in the current Rig. You can match the knob position to the saved parameter by turning the knob until it lights Amber or Green again.
When a Control knob isn’t active in the current screen, it is not lit.
Phones Output
The Phones output is a 1/4-inch TRS jack that drives a pair of headphones with the same signal that is being sent out of the Main outputs of Eleven Rack. This can be either the output of the current Rig when using Eleven Rack, or the out­put of Pro Tools or other applications when us­ing Eleven Rack as an audio interface.
The headphone output level is adjusted in tan­dem with the Main volume when you turn the Volume knob on the front panel of Eleven Rack or adjust the Main volume from within Pro Tools. If you want the headphone volume to differ from that going to your speakers, you can adjust the Headphone Offset setting in User Op­tions mode.
For more information on Headphone Offset, see“Headphone Volume” on page 94.
The Output To Amp 1 (L) is one of two outputs specifically designed for connecting to the input of a guitar amplifier. Since most amplifier input jacks are located on the amp’s front panel, we put one of these jacks on the front panel of Eleven Rack for easy patching.
The other Output to Amp jack is located on the back of Eleven Rack. It can be used indepen­dently of Output 1, or along with it for stereo amplifier configurations. The Output to Amp jacks can output a live guitar signal in real time as you play, or a pre-recorded signal from Pro Tools, for re-amping purposes.
You can select from specific points in the signal chain to feed each Output To Amp jack. This lets you choose the amount of processing you want on the output signal.
Guitar Input with True-Z
The Guitar input is a 1/4” TS, instrument-level input. Designed for electric guitars, the jack also works well with bass and acoustic guitars with pickups, or even vintage electric pianos.
Most recent keyboards have line-level out­puts and shou ld be con nected t o the Line in­puts on the back panel of Eleven Rack.
Eleven Rack features a special variable-imped­ance circuit called True-Z, which automatically changes the input impedance of the Eleven Rack guitar input depending on which amp or effects model is first in the signal chain of the current Rig.
True-Z alters the frequency response of your gui­tar signal by loading your pickups in the same manner as plugging into a real amp or effect. This feature can also be manually controlled and saved as part of a Rig setting.

The Eleven Rack back panel provides the following:
FX Loop I/O
The FX Loop I/O is a pair of 1/4-inch TRS inputs and outputs, which can be used to insert a mono or stereo external effects processor into the gui­tar signal. A switch is provided to adjust the sig­nal level to be suitable for either a line-level ef­fects processor (Rack FX) or a guitar-level effects processors (Stompbox FX).
Main Outputs
The Main output section includes a stereo, XLR, line-level analog output pair. Connect these to studio monitors, a power amp, mixer, or PA sys­tem.
The Gnd Lift switch is useful for suppressing hum in some situations, but should usually be left switched off unless it is really needed.
Output To Amp 2 (R)
The Output To Amp 2 (R) is one of two outputs specifically designed for connecting to the input of a guitar amplifier or effect. It can be used in­dependently of Output 1 (located on the front panel), or along with it for stereo amplifier con­figurations.
Digital Inputs and Outputs
AES/EBU
The AES/EBU In and Out ports are balanced three-conductor XLR connectors that can run at up to 24-bit, 96 kHz resolution.
The AES/EBU format is used in many profes­sional digital converters, recorders, and signal processors.
Eleven Rack User Guide10
S/PDIF
MIDI I/O
The S/PDIF In and Out ports are unbalanced two-conductor phono (RCA) connectors that can run at up to 24-bit, 96 kHz resolution.
The Sony/Philips Digital Interface Format (S/PDIF) is used in many professional and con­sumer CD recorders and DAT recorders. To avoid RF interference, use 75-ohm coaxial cable for S/PDIF transfers and keep the cable length to a maximum of 10 meters.
Eleven Rack can use either AES/EBU or S/PDIF, but not both at once. For informa­tion on switching between digital formats, see “Digital Format” on page 58.
AC Power Input
The AC power input accepts a standard IEC power cable (one is included with Eleven Rack). The power supply in Eleven Rack is universal, so wherever you go, all you need is a standard IEC power cable with the correct plug for your re­gion.
The MIDI In and MIDI Out ports are standard 5-pin MIDI ports, each providing 16 channels of MIDI input or output. These ports can interface with a variety of MIDI devices
When Eleven Rack is used as a standalone pro­cessor, the MIDI jacks are used to communicate with MIDI foot controllers, sending and receiv­ing program changes and continuous controller data.
Exp Pedal/Ext Footswitch Input
The Exp Pedal/Ext Footswitch input supports an expression pedal or a momentary footswitch (single or dual). You can control sweepable pa­rameters (like Wah, Volume and Multi FX) with an expression pedal, or switchable settings (like Rig switching, amp channel switching, and ef­fects on/off) with a footswitch.
Line Inputs
The Line inputs accept one stereo or two mono line-level analog signals. The Level switch lets you choose between +4 or –10 dBV, for compat­ibility with professional and consumer gear.

Chapter 3: Exploring Rigs

Overview

Eleven Rack is a powerful guitar signal processor that delivers the tone of a wide variety of ampli­fiers, speaker cabinets, microphones, and effects units. The combination of all of this gear and their control settings make up a Rig.
Eleven Rack comes loaded with over 100 Rigs that showcase the range of tones our collection of amps and effects can achieve. The built-in Rigs are a good place to start, but the power of Eleven Rack really comes into play when you create your own.
You can audition, manage, edit and create Rigs right from the front panel of Eleven Rack. When using Eleven Rack with Pro Tools LE, the built­in Eleven Rack Control window offers another convenient way to do this work.
For details on working with Rigs from within Pro Tools, see “The Eleven Rack Control Window” on page 76.

Rig Select Mode

When you turn on Eleven Rack, it’s already in Rig Select mode. In this mode, you can turn the Scroll wheel to select a Rig. Pressing the SW 1 button will cycle the display through these three display modes:
•Default mode
•Simple mode
• Details mode
Default Mode
This mode shows the Rig number and name, and provides a set of amp or effects controls that you can change without entering Rig View.
Chapter 3: Exploring Rigs 13
Simple Mode
Rig name
Rig Bank
Rig number
This mode shows the Rig number and name in the largest type possible. Perfect for seeing from across a dark stage.
Details Mode
This mode lists the amp, cabinet, and effects models that are used in the current Rig, plus their on/off status.
The 208 Rigs in Eleven Rack are arranged into two sets of 26 banks, each containing four Rigs. Each bank is marked with a letter, from A to Z. For example, the third preset in bank D is re­ferred to as D3. Banks with lowercase letters are factory presets, and those with uppercase letters are the user banks.
User Rigs and Factory Rigs
By default, all 104 user Rigs are copies of the 104 factory Rigs. This gives you a place to start when you set out to make your own Rigs. As you scroll through, notice that when you get past the end of the uppercase (user) Rigs, you’ll then begin to see the lowercase (preset) Rigs.
The user Rigs are yours to edit, change, copy, and mangle as you see fit. The preset Rigs will al­ways stay the same. If you make changes to a preset Rig and want to save it, you can save it as a new User Rig.

Rig Organization

Eleven Rack has storage for 208 Rigs. Half of these are factory presets, and the other half are user-editable Rigs. You can also save and store an unlimited number of your favorite Rigs as plug-in settings files on your computer.
Eleven Rack User Guide14

Selecting Rigs Live

When using Eleven Rack in live performance sit­uations, we recommend using a footswitch ac­cessory or a dedicated MIDI foot controller to switch from Rig to Rig.
For information on using a footswitch ac­cessory, see “External Pedals” on page 93, and see “Eleven Rack MIDI CC Controllers” on page 95 for information on using a MIDI foot controller.

What’s In A Rig?

Figure 3. Eleven Rack Rig devices
Each Rig in Eleven Rack contains the following devices for processing your guitar signal, and each of them has settings you can control:
• Amplifier
• Speaker cabinet and microphone
• Seven simultaneous effects (such as Wah, Dis­tortion, Modulation, and Reverb)
•Volume pedal
• FX Loop
In addition, there are a group of “Utility” set­tings in each Rig:
• Input, which lets you manipulate the True-Z input impedance circuitry
• Output, which lets you change the Rig vol­ume, To Amp output volume, and switch the Rig output between mono and stereo
• Tempo, which lets you set the Rig tempo
• Pedal, which lets you configure an external footswitch or expression pedal accessory
• Display, which lets you set the device whose controls are displayed in Rig Select view (like Amp, Mod, or FX1)

Rig View

Rig View is a special editing mode you access by pressing the Edit/Back button on the front panel of Eleven Rack. When you’re done editing, press the Edit/Back button again to get back to the main Rig Select mode.
If you make changes you want to save, be sure to use the Save button before switching to a different Rig. For details, see “Saving Your Work” on page 19.
In Rig View, you can access every aspect of the current Rig, from the amp, cabinet, and micro­phone type, all the way to choosing effects, and changing their order in the signal chain.
Rig View
Once you’ve entered Rig View, you’ll see a selec­tion of icons, each representing a different de­vice or utility setting within the current Rig. Turn the Scroll wheel to select the element you want to access.
As you scroll through the list, certain functions will be assigned to the lit Control Knobs, like choosing the type of amp or effect you want to use.

The Amps

‘59 Tweed Lux
Based on a classic late-50s tube combo amp with a single 12-inch speaker and a pair of 6V6 tubes delivering 15 watts, the ‘59 Tweed Lux model is the picture of vintage simplicity. With just a simple treble-cutting tone control, the Tweed Lux delivers crunchy clean sounds when used with single-coil pickups, and fat leads when driven with humbucking pickups.
The inputs on this model are “jumped” so you can feed both the Instrument and Mic inputs in parallel.
’59 Tweed Bass
This section takes you through all of the emu­lated amplifiers available in Eleven Rack, and touches on any special features and controls each amp offers.
Eleven Rack User Guide20
Based on a late-50s low-wattage tube bass combo amp, the ‘59 Tweed Bass model has a tight bass response and a warm, twang-friendly high-end. Along with controls for Bass, Middle (midrange), and Treble, a negative feedback Presence control also allows for more tweaking of the high-end frequencies.
Just like the Tweed Lux, the Tweed Bass is also “jumped” so you can feed both the Bright and Normal inputs in parallel.
’64 Black Panel Lux Vibrato and Normal
The amp we based the ‘64 Black Panel Lux Vi­brato and Normal models on is regarded by some as the ultimate small club amp. A 60s tube combo with a single 12-inch ceramic-magnet speaker and a pair of 6V6s putting out just over 20 watts, this amp has long been a standard in the studio as well as onstage.
At low volumes its crisp, clean high-end has been favored by country rockers, but push the amp past 7 with a humbucking pickup, and you’ve got an amazingly dynamic lead tone. For Eleven, we’ve modeled both channels of this classic blackface-era amp.
The Lux Vibrato model has two gain stages and the tremolo effect is toggled using SW2. Lux Normal has a single gain stage and tremolo is al­ways on, unless the Intensity control is rolled all the way off.
’66 AC Hi Boost
Originally released in 1958, the British amp we based our ‘66 AC Hi Boost model upon went through a few design changes that would even­tually define the sound of British pop/rock in the ‘60s.
First available as a modification mounted in the back of the amp, the “Top Boost” circuit added an extra tube and controls for Treble and Bass. It became so popular that it eventually became a part of the standard componentry of the amp.
The glassy high-end and chime of the AC Hi Boost lends a classic propulsion to rhythm gui­tar parts, and at higher gain settings, singing lead tones are a snap to achieve.
For our model, we’ve “jumped” the Normal and Brilliant channels. The Cut (presence) control is active on both channels. However, just like the original, the Treble and Bass controls are only part of the Brilliant channel, and have no effect on the Normal channel.
Go to the second Control page and press SW2 to toggle the tremolo on and off.
Chapter 3: Exploring Rigs 21
’67 Black Panel Duo
’69 Plexiglas
Without a doubt, the blackface-era amp we based our ‘67 Black Panel Duo model upon is considered one of the greatest combo amps ever made. With two 12-inch ceramic-magnet speak­ers and a quartet of 6L6 tubes pushing 80 watts, no concert stage has been complete without one since it was introduced in the late 60s.
One of the main reasons for the amp’s popular­ity is that it can maintain classic vintage clean sounds even at high volume levels. Another spe­cial Black Duo feature is the inclusion of a Bright switch.
For our model, just like the original, as you turn the Volume knob up, the Bright switch has less of an effect. Dial the Volume knob around 3 or 4 with the Bright switch on, and you’ll get that ul­tra-clean snap that it’s famous for.
On the first Control page, SW2 is set to toggle the Bright switch on and off. On the second page, SW2 toggles vibrato on and off.
Based on one of the most highly sought-after high-volume amplifiers of the late 1960s, our ‘69 Plexiglas model delivers no-nonsense British crunch. The original amp's dual 4x12 cabinets and 100-watt head offered unprecedented vol­ume and power for the time, helping to usher in the era of the Guitar God.
For our model, we’ve based it on the legendary 100-watt 1968/69 version. We’ve also “jumped” both channels, for further gain.
’82 Lead 800
Based on the early-80s descendent of the amp we based our Plexiglas model upon, the ‘82 Lead 800 adds a higher-gain cascaded preamp design and a master volume control. Unlike the high­volume heads of the 60s, which needed to be on 10 to achieve an overdrive sound, this amp could conjure up real distortion at any volume level, and that made it very popular in the bur­geoning 80s heavy metal scene.
Eleven Rack User Guide22
’85 M-2 Lead
which leads to a rounder, thicker sound. The Bright switch circuit has progressively less effect as the gain is raised, and no effect when the pre­amp is set to 10.
Toggle the Bright switch on and off with the SW2 button.
Based on a classic mid-80s high-end tube combo amp, the ‘85 M-2 Lead model delivers hot­rodded overdrive and searing solo tones. With a full complement of tone controls and indepen­dent input volume, overdrive and master vol­ume controls, the gain structure can be tweaked to your heart's content.
The M-2 Lead emulation is based on the lead channel with the fat, bright, and gain boost op­tions on.
‘89 SL100 Drive, Crunch, and Clean
Our ‘89 SL100 model is based on a late-80s high­gain 100-watt tube head, which was popular for its singing sustain and clear articulation. The Bright switch on the Clean and Crunch models boosts the high-end for lead lines and cutting tones.
For the Drive model, we simulated a bright switch modification that was popular for this amp. Set to Normal, the amp is stock. With Bright engaged, the treble boost that would nor­mally happen at lower gain settings is removed,
’92 Treadplate Modern and Vintage
Released in 1989, the amp that inspired our ‘92 Treadplate Modern and Vintage models seemed cooler than a high-performance racecar. With more tone-tweaking options and distortion than any amp before it, the amp became the in­dustry standard for players looking to achieve a massive sound.
With the ability to run on either 6L6 or EL34 tubes, this amp offered a choice between either tube or silicon diode rectifier circuits. On top of that, an AC power selection switch offered a Bold or a Spongy option, which would drop the voltage like a Variac for a more “brown” sound.
For our Treadplate, we modeled two different channels and selected the appropriate rectifier and AC power switch setting. For Treadplate M (for Modern), we set it on the Red channel using 6L6s, a silicon rectifier, and the Bold power set­ting for a tight, aggressive tone. For Treadplate V (for Vintage), we modeled the orange channel with 6L6s, a tube rectifier, and the spongy power setting for a more fluid lead tone.
Chapter 3: Exploring Rigs 23
DC Modern Overdrive and DC Vintage Crunch
Rather than base these two models on any two specific amps, we blended the characteristics and features of many of our favorite amps to cre­ate a couple of absolute monsters.
The Modern model augments a modified high­gain British amp flavor with a Bright switch and classic American-style Tremolo. The Vintage model combines tonal attributes of 50s and 60s­era American tube amps, with added gain poten­tial and a Bright switch.
On the first Control page, SW2 is set to toggle the Bright switch on and off. On the second page, SW2 toggles vibrato on and off.
When you view the Amp controls, a Page indi­cator is displayed to show you which page of controls you’re viewing. Turn the Scroll wheel to switch pages.

Tremolo Controls
Some amps, like the ‘64 Black Panel Lux Vibrato, ‘66 AC Hi Boost , and DC Modern Overdrive, fea­ture authentic Tremolo circuits. Here’s what those controls do:
Digidesign Eleven Rack is not affiliated with, sponsored, or endorsed by the makers of the amplifiers that are emulated in this product.

General Amp Controls

The Amp controls can be accessed in the Default view of Rig Select mode, or by selecting the AMP device in Rig View and pressing CONTROLS. There are two pages of controls for every amp. These controls are configured and named to closely match the amps we modeled for Eleven Rack.
Speed Lets you set the speed of the Tremolo ef­fect’s amplitude modulation.
Sync When set to a rhythmic value, the SYNC control sets the Tremolo’s speed to cycle at the selected rhythmic interval, in sync with the Rig tempo. When set to “OFF”, the speed is not syn­chronized and can be manually set with the SPEED control.
Depth Sets the amount of amplitude modula­tion.
When using Eleven Rack with Pro Tools, you can choose to sync tremolo and other ef­fects to either the Rig tempo or the tempo of the Pro Tools session. For more details, see “Rig Tempo” on page 79.

Each of the amps in Eleven Rack has a Noise Gate, which can be used to suppress noise com­ing from the instrument before the signal reaches the amp model. Noise can be especially problematic when boosted heavily at high-gain settings. Its controls are:
Noise Gate Lets you set the threshold of the Noise Gate. Adjust this control until you find a good balance between effective gating and cut­ting off the signal prematurely on sustained notes.
Rel Sets the release time for the envelope that runs the Noise Gate. A longer release time can sound more natural, while a shorter release can help to rein in a really noisy signal.
The Noise Gate remains usable even when the amp model has been bypassed.
Amp Output
The amp models in Eleven Rack are so faithful to the classics they’re based on that the output level can increase significantly as the preamp, volume or master controls are cranked. Also, from one amp the next, output levels will vary depending on their design.
The OUTPUT control lets you compensate for those differences with no coloration added to the tone you’re getting.
The amp output volume can also be ac­cessed in Rig View, by selecting AMP and manipulating the Amp Out Vol Control knob.
Bypass
The Bypass control toggles the amp simulation on and off, leaving any effects in the Rig un­changed.

Eleven Rack User Guide26

The Effects

This section takes you through the effects avail­able in Eleven Rack.
Wah Effects
Black Wah
Volume Pedal
The Volume Pedal is a sweepable volume con­trol. You can use it to fade notes or chords in and out, or to vary the volume of your signal in real time, for timbral or rhythmic effects.
The Volume Pedal is most useful when con­trolled with an expression pedal or MIDI foot controller.
For more information about using an ex­pression pedal or MIDI foot controller, see “External Foot Controllers” on page 38.
Black Wah is a standard wah pedal effect, offer­ing a sweepable resonant filter that lets you add animation and special timbral effects to the gui­tar signal.
Like the Volume Pedal, wah effects like Black Wah are particularly useful when controlled with an expression pedal or MIDI foot control­ler.
Shine Wah
Shine Wah works and sounds similar to Black Wah, but with a vintage-style filter circuit and sweep response.
Chapter 3: Exploring Rigs 27
Distortion Effects
Tri-Knob Fuzz
The pedal that inspired Tri-Knob Fuzz was a transistor-based unit, originally popular with lead guitarists searching for ever-higher gain in the 70s. It shone again in the 90s grunge rock scene, probably pushed further into woolly grind than its makers would have ever antici­pated.
Vol ume Sets the overall output volume of the ef­fect.
Sustain Sets the gain of the fuzz circuit.
Tone Changes the tonal balance of the effect,
from deep and full of sub-bass to high and shrill.
Green JRC Overdrive
Green JRC Overdrive was inspired by a low-gain 70s overdrive pedal, loved by blues and blues­rock players the world over for its sweet, singing sting. I t can be used to simply drive an amp’s in­put section into gentle clipping, or supply some dirty glow of its own.
Modulation Effects
Flanger
BlackOp Distortion
Inspired by an 80s-era op-amp-based distortion pedal, BlackOp Distortion offers massive crunch and power. Its hard-clipping drive can squeeze aggressive rhythm and lead tones out of soft­sounding vintage amps, and create surprisingly hard-edged tones when paired with more mod­ern amps.
Eleven Rack User Guide28
Originating from the act of pressing on the flanges of tape reels, and becoming even more popular with the advent of analog pedals, the Flanger effect can be coaxed into bell-like reso­nant sweeps, or add a silky, shimmering sheen. This effect works well when positioned before or after the amplifier in the signal chain.
Pre-Dl Sets the amount of pre-delay, which changes the phase relationship between the dry signal and the delayed signal, with timbral re­sults.
Depth Sets the amount of delay. The higher the setting, the more “jet-engine” artifacts will be introduced.
Fdback Sets the amount of signal fed back into the modulated delay. Higher settings introduce more ringing, whistling artifacts.
Chorus/Vibrato Toggles the effect between Cho­rus and Vibrato.
When set to CHORUS, the Rate and Depth controls are inactive. Likewise, when set to VIBRATO, the Chorus control will not function.
C1 Chorus/Vibrato
Based on a heavyweight late-70s analog cho­rus/vibrato pedal, CI Chorus/Vibrato offers warm, liquid modulation effects. In Chorus mode, the signal is routed through a modulated short delay, which is mixed with the dry signal, creating a washy, doubled sound.
In Vibrato mode, the dry signal is absent and there is more control over the depth of pitch modulation, allowing for everything from an understated “wobble” to wacky, synth-like pitch modulation.
Chorus Sets the intensity and speed of the Cho­rus effect, only when the Chorus/Vibrato switch is set to Chorus.
U Phaser
The psychedelic-era phaser that inspired our U Phaser effect was traditionally paired with an expression pedal that could be used to vary the rate of pitch modulation over time. Like the C1, you can choose to run it as a Chorus, with the modulated and dry signals mixed together, or in Vibrato mode, which leaves the pitch-modu­lated signal alone, with rippling, disorienting ef­fects.
Chorus/Vibrato Toggles the dry signal on (Cho­rus) and off (Vibrato).
Depth Sets the depth of the Vibrato effect, only when the Chorus/Vibrato switch is set to Vi­brato.
Rate Controls the Vibrato rate, only when the Chorus/Vibrato switch is set to on.
Chapter 3: Exploring Rigs 29
Orange Phaser
Based on a more basic analog phaser, Orange Phaser offers a more subtle, warm phas­ing effect.
Speed Controls the Phaser effect’s rate of modu­lation.
Sync Synchronizes the modulation rate to the Rig tempo by a specific rhythmic subdivision.
Reverb Effects
Blackpanel Spring Reverb
Blackpanel Spring Reverb was inspired by a clas­sic outboard tube-driven spring reverb. It can add a surfy twang and dark, warm ambience to your signal.
Mix Controls the blend between dry and rever­bed signal.
Roto Speaker
Inspired by the rotating speaker cabinets that made classic tonewheel organs roar, Roto Speaker offers added motion and vintage grit.
Speed Sets the speed of the rotating speaker ef­fect, in three increments, Slow, Fast, and Brake (stopped).
Balance Sets the blend between the upper and lower rotors of the rotating speaker.
Type Chooses between various types of rotary speakers.
Decay Controls the length of the reverb’s decay.
Tone Applies a high-cut EQ, making the reverb
tone darker.
Eleven SR
A smooth, clean digital reverb, Eleven SR is based on the popular Reverb One Pro Tools plug-in from Digidesign.
Pre-Dly Sets the amount of pre-delay, which changes the time relationship between the dry signal and the reverbed signal. As this setting is turned higher, the apparent size of the synthe­sized reverb “room” grows larger.
Type Selects from a variety of different reverb types.
Eleven Rack User Guide30
Delay Effects
Tape Ec ho
Inspired by the ultimate vintage solid state tape echo unit, Tape Echo supplies supple, crunchy echoes, and can, with a flick of the wrist, can be pushed into swells of wild self-oscillation, each repeat more murky, dusty, and gritty than the next. A classic.
Rec Lev Controls the signal level running to the tape circuitry. Higher settings create a more dis­torted tone color.
Head Simulates the alignment (or misalign­ment) of the tape head with the tape, which af­fects the tone of the delay.
BBD Delay
When “bucket brigade” analog delays arrived in the mid-70s, their relatively small size and solid­state reliability made them a godsend to tape loop-addled guitarists. It went on to become a classic of its own, with a smooth, round delay sound and a Chorus-Vibrato mode that let it double as a modulation effect.
Input Sets the input level to the delay effect. Cranked up, it can push the signal into useful distortion.
Mod Switches the modulation effect between Vi­brato (only the delayed signal is passed) and Chorus (both the dry and delayed signal are passed.)
Wow Controls the amount of wow and flutter in the tape mechanism. Lower settings minimize fluctuations of pitch and tone color, and higher settings accentuate it.
Hiss For some serious authenticity in your tape echo tone, this switch Toggles modeled analog tape hiss in or out of the signal. With high feed­back settings, the tape hiss can push the echo into self-oscillating mayhem.
Depth Controls the level of modulation of the delayed signal.
Noise Toggles modeled analog hiss in or out of the signal.
When Hiss or Noise is turned on in one of the delay effects and the feedback level is sufficiently high, the delay will self-oscil­late and make noise, even when bypassed. If this occurs, turn down the feedback con­trol.
Chapter 3: Exploring Rigs 31
EQ & Compressor Effects
Graphic EQ
Useful for simple frequency sculpting, a good Graphic EQ can find a place in almost any ped­alboard. Graphic EQ can wring a variety of tones out of other pedals, such as when placed before Distortion effects. The EQ can also be used as a signal booster when positioned in front of amps.
Gray Comp

General Effects Controls

Sync
The time-based effects in Eleven Rack (such as Chorus, Delay and Flanger) can be set to syn­chronize with Rig or Session tempo. When the Sync control on these effects is set to a rhythmic subdivision of the incoming tempo, the effect will lock to it. When Sync is set to Off, the Rate or Delay control on the effect will take over, and the rate of modulation or delay can be set by hand.
Delay+ & Fine
These two controls are included in both delay ef­fects. Delay+ quadruples the available delay time, for when longer echoes are needed. Fine switches the delay’s Rate control into a fine-ad­just mode, where the delay time can be set by the millisecond with the Scroll wheel. Press Fine again to return to normal mode.
Inspired by a well-loved solid-state 70s compres­so r ped al, Gray Com p can add singing sustain to leads or lend power and girth to chunky rhythm guitar parts.
Sustain Sets the threshold, and thus, the amount of compression, in the Compressor ef­fect.
Level Sets the overall output volume of the ef­fect.

Plugging in Your Guitar
Connect your guitar to the Guitar input on the front of Eleven Rack with a 1/4” TS cable.
Eleven Rack User Guide34
Connecting Eleven Rack to a PA System
The simplest way to play live with Eleven Rack is to connect it directly to the PA mixer using the Main XLR outputs. When doing so, it is recom­mended to tell the person running the PA sys­tem that you are providing a line-level signal, rather than a mic-level signal, so that they can correctly set the input on the console.
If a buzz or hum occurs, try toggling the Gnd Lift switch.

Using an Amp Onstage

PA Mixer
Figure 6. Eleven Rack connected to the PA mixer and an onstage amplifier
In some cases, having an amplifier onstage can be handy for monitoring or tone reasons. Eleven Rack makes it easy to feed your signal to both a PA mixer and an amp.
Connecting Eleven Rack to a Guitar Amplifier
The Output To Amp outputs on Eleven Rack can be connected to one or more guitar amplifiers using standard 1/4” TS cables.
• If using a single, mono amplifier, use the Out­put To Amp 1 (L) output.
• If using two amplifiers, or an amp with stereo inputs, connect each Output To Amp output to a separate amp or channel input.
Sending the Correct Signal
Eleven Rack lets you choose the point in the sig­nal path that feeds each Output To Amp jack. If you’re using an amplifier with a distinct tone of its own, you may want to send it a signal with little processing (for example, only the effects) so the sound of the amp can ring through clearly.
If you prefer to use the amp simulations in Eleven Rack to set your tone, you will want to send the signal just after the amp simulation, but before the cabinet simulation, to your am­plifier.
Chapter 4: Eleven Rack Live Setup 35
To set the type of signal to send to the amp:
1 Press and hold the Edit/Back button to show
the User Options mode.
2 Scroll to Outputs To Amp with the Scroll wheel.
3 Press SW1 to enter the Outputs To Amp
screen.
4 Choose the output you plan to use to feed the
amp, with the Scroll wheel.
5 Set the Signal control to one of the following,
using the first lit Control knob:
Rig Input (no processing)
Amp Input (pre-amp effects only)
Amp Output (effects and amp simulation)
6 Press Edit/Back twice to leave User Options
mode.
The signal level running to each Output To Amp output can be set on a per-rig basis in the Output section in Rig View or in the Eleven Rack Control window. For more de­tails, see “OUTPUT” on page 17, or “Out­put to Amp Selectors” on page 80.
Because Eleven Rack simulates various pre­amps and tone circuits, you may want to by­pass your amp’s preamp and tone circuitry by plugging into the amplifier’s effects re­turn jack(s), if available, rather than the standard input(s). If your amp does not have an effects loop, try setting the amp controls for maximum transparency (EQ flat, gain stages set to clean.)
Eleven Rack User Guide36

Effects and Foot Controllers

Figure 7. Effects and foot controller connections
Connecting Effects
Use the FX loop jacks to connect stomp boxes, rack effects or other external processors to the live guitar signal. These can be either rack or stompbox effects, or a combination thereof, in mono or stereo. The FX Loop accepts 1/4” plugs.
To connect external effects to Eleven Rack:
1 Connect the FX Loop Send output on Eleven
Rack to the input of your first (or only) effects unit. If the unit is mono, use the Left/Mono out­put. If the unit is stereo, use both outputs.
2 Connect the output of the final (or only) ef-
fects unit to the FX Loop Return input on Eleven Rack. If the unit is mono, use the Left/Mono in­put. If the unit is stereo, use both inputs.
If using a combination of mono and stereo effects, it is usually best to put the mono ef­fects units first in the chain, with the final mono unit connected to the mono input on the first stereo unit.
3 If using a line-level rack effect, toggle the Rack
FX/Stompbox FX switch to the Rack FX posi­tion. If using a guitar-level stompbox effect, tog­gle the switch to the Stompbox FX position.
If using a combination of guitar-level (stompbox) and line-level (rack) effects, it may be preferable to put the guitar-level unit(s) first in the chain. If your line-level unit(s) have guitar-level outputs available, the order is not important. See your effects unit(s) documentation for more details.
The User Options and Rig View modes in Eleven Rack contain a variety of settings that control the behavior of the FX loop. For more information, see “The Amps” on page 20 and “FX Loop” on page 93.

External Foot Controllers

Eleven Rack has a 1/4” TRS input that can accept input from an expression pedal or a single or dual momentary footswitch.
Chapter 4: Eleven Rack Live Setup 37
Expression Pedal
MIDI Foot Controller
An expression pedal can be used to control con­tinuously variable parameters within Eleven Rack, such as volume or wah position.
In addition to commonly-used expression ped­als, a standard volume pedal with a “Y” adapter cable (two 1/4-inch TS plugs to one 1/4-inch TRS plug) can be used, though keep in mind that the taper of the potentiometer in a volume pedal is exponential, rather than linear as in an expres­sion pedal.
Momentary Footswitch
(Single or Dual)
Most single or dual momentary footswitches can be used to toggle various switched functions within Eleven Rack, such as effects on/off and cycling through rigs.
Choose a momentary footswitch with a 1/4-inch TS (single switch) or 1/4-inch TRS (dual switch) connection.
For more information on the use of pedals and footswitches with Eleven Rack, “Exter­nal Pedals” on page 93.
You can connect a MIDI foot controller to the MIDI input on Eleven Rack, providing control over a larger range of simultaneous parameters.
For details on Eleven Rack controls you can control with a MIDI foot controller, see “Eleven Rack MIDI CC Controllers” on page 95.

Display Mode and Visibility

When playing live, you may find it easier to keep track of what Rig is selected by switching the display to Simple mode.

Chapter 7: Pro Tools Configuration 51

Configuring Pro Tools LE

Pro Tools System Settings
In the Playback Engine dialog, Pro Tools LE lets you adjust the performance of your system by changing system settings that affect its capacity for processing, playback, and recording.
In most cases, the default settings for your sys­tem provide optimum performance, but you may want to adjust them to accommodate large or processing-intensive Pro Tools sessions.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the buffer used to handle host processing tasks such as RTAS plug-ins.
• Lower Hardware Buffer Size settings are useful for improving latency issues in certain record­ing situations or for improving certain system performance problems. On Pro Tools LE sys­tems, lower settings reduce all input-to-out­put monitoring latency on any record-armed tracks or Auxiliary Input tracks with live in­puts.
• Higher Hardware Buffer Size settings are use­ful for sessions that are using more RTAS plug­ins for playback. These settings allow for more audio processing. They can also be useful to reduce errors on machines that require a higher buffer size.
In addition to causing slower screen re­sponse and monitoring latency, higher Hardware Buffer Size settings can increase the latency caused by RTAS plug-ins, and affect the accuracy of plug-in automation, mute data, and MIDI track timing.
Playback Engine dialog (Structure plug-in installed)
Eleven Rack User Guide52
To change the Hardware Buffer Size:
1 Choose Setup > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
Low Latency Monitoring mode can be used to circumvent latency caused by higher buf­fer settings when recording. This can be tog­gled on and off by clicking Options > Low Latency Monitoring in Pro Tools.
RTAS Processors
The RTAS Processors setting determines the number of processors in your computer allo­cated for RTAS (Real-Time AudioSuite) plug-in processing.
With computers that have multiple processors, or that feature multi-core processing or hyper­threading, this setting lets you enable multipro­cessor support for RTAS plug-ins. Used in combi­nation with the CPU Usage Limit setting, the RTAS Processors setting lets you control the way RTAS processing and other Pro Tools tasks are handled by the system.
For example:
• For sessions with large numbers of RTAS plug­ins, you can allocate 2 or more processors to RTAS processing and set a high CPU Usage Limit.
• For sessions with few RTAS plug-ins, you can allocate fewer processors to RTAS processing and set a low CPU Usage Limit to leave more CPU resources available for automation accu­racy, screen response, and video.
• Depending on the importance of video and overall screen response, and on the density of automation being employed, try different combinations of RTAS Processors and CPU Us- age Limit settings to achieve the best results. For example, to improve screen response in a medium-sized session using a moderate num­ber of RTAS plug-ins, try reducing the number of RTAS plug-ins, but keep the CPU Usage Limit set to the maximum (up to 99% on a single processor system).
To set the number of RTAS Processors:
1 Choose Setup > Playback Engine.
2 From the RTAS Processing pop-up menu, select
the number of available processors you want to allocate. The number of processors available var­ies depending on how many processors are available on your computer:
• Select 1Processor to limit RTAS processing to one CPU in the system.
• Choose 2 Processors to enable load balanc­ing across two available processors.
• On systems running four or more proces­sors, choose the number of processors for RTAS processing.
3 Click OK.
System Usage Window and RTAS Processing
The System Usage window (Window > System Us­age) displays the combined amount of RTAS
processing occurring on all enabled processors with a single indicator, regardless of how many processors are available in the system. If the Sys­tem Usage Window shows that you are at the limit of available resources, increase the number of RTAS processors and adjust the CPU Usage Limit setting.
Chapter 7: Pro Tools Configuration 53
CPU Usage Limit
RTAS Engine (RTAS Error Suppression)
The CPU Usage Limit setting controls the per­centage of CPU resources allocated to Pro Tools host processing tasks. Used in combination with the RTAS Processors setting, the CPU Usage Limit setting lets you control the way Pro Tools tasks are carried out by the system.
•Lower CPU Usage Limit settings limit the effect of Pro Tools processing on other CPU-inten­sive tasks, such as screen redraws, and are use­ful when you are experiencing slow system response, or when running other applications at the same time as Pro Tools.
•Higher CPU Usage Limit settings allocate more processing power to Pro Tools, and are useful for playing back large sessions or using more RTAS plug-ins.
The maximum available CPU Usage Limit de­pends on the number of processors in your com­puter and on the number of processors you spec­ify for RTAS processing. This value can range from 85% for single-processor computers, and 99% for multiprocessor computers (which dedi­cate one entire processor to Pro Tools).
The RTAS Engine option determines RTAS error reporting during playback and recording. This is especially useful when working with instrument plug-ins.
You should only enable RTAS error suppression if you are experiencing frequent RTAS errors that are interrupting your creative workflow. When RTAS error suppression is enabled, you can experience a degradation of audio quality. However, this may be acceptable in order to avoid interrupting playback and recording when working with instrument plug-ins. Be sure to disable RTAS error suppression when you need to ensure the highest possible audio qual­ity, such as for a final mix.
To enable RTAS error suppression:
1 Choose Setup > Playback Engine.
2 Select Ignore Errors During Playback/Record.
3 On Mac, you can also select Minimize Additional
I/O Latency.
4 Click OK.
On multiprocessor computers, the maximum CPU Usage Limit is reduced when you use all your processors (as selected in the RTAS Processing pop-up menu). For example, on dual-processors, the limit is 90%. On four-processor computers, the limit is 95%.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, select
the percentage of CPU processing you want to allocate to Pro Tools.
3 Click OK.
Eleven Rack User Guide54
RTAS Error Suppression Options
Ignore Errors During Playback/Record When en-
abled, Pro Tools continues to play and record even if the RTAS processing requirements ex­ceed the selected CPU Usage Limit. This can result in pops and clicks in the audio, but does not stop the transport.
Minimize Additional I/O Latency (Mac Only) When enabled, any additional latency due
to suppressing RTAS errors during playback and record is minimized to 128 samples. Suppressing RTAS errors requires at least 128 samples of ad­ditional buffering on some systems. If this op­tion is disabled, the buffer is half the H/W Buffer Size, or at least 128 samples (whichever is greater). If you are on an older, slower computer, you may want to disable this option to avoid ad­verse performance.
This option is only available on Mac if the Ignore Errors During Playback/Record option is enabled.
The optimum DAE Playback Buffer Size for most disk operations is 1500 msec; Level 2 (Default).
DAE Playback Buffer Size settings lower than 1500 msec; Level 2 (Default) may improve playback and recording initiation speed, as well as preview in context in DigiBase brows­ers. However, a lower setting may make it dif­ficult to play or record tracks reliably with sessions containing a large number of tracks or a high density of edits, or with systems that have slower or heavily-fragmented hard drives.
DAE Playback Buffer Size settings higher than 1500 msec; Level 2 (Default) allow higher track count, higher density of edits in a session, or the use of slower hard drives. However, a higher setting may increase the time lag when starting playback or recording, starting pre­view in context from DigiBase browsers, or cause a longer audible time lag while editing during playback.
DAE Playback Buffer Size
The DAE Playback Buffer Size setting determines the amount of memory DAE allocates for disk buffers. In addition to levels, the DAE Playback Buffer Size shows values in milliseconds, which indicate the amount of audio buffered when the system reads from disk.
Using a larger DAE Playback Buffer Size leaves less system memory for other tasks. The default setting of 1500 msec (Level 2) is recommended unless you are encountering –9073 (“Disk too slow or fragmented”) errors.
To change the DAE Playback Buffer Size:
1 Choose Setup > Playback Engine.
2 From the DAE Playback Buffer pop-up menu, se-
lect a buffer size. Memory requirements for each setting are shown at the bottom of the Playback Engine dialog.
3 Click OK.
If Pro Tools needs more system memory for the DAE Playback Buffer, it will prompt you to re­start your computer.
Chapter 7: Pro Tools Configuration 55
Cache Size
The Cache Size setting determines the amount of memory DAE allocates to pre-buffer audio for playback and looping when using Elastic Audio.
Minimum Reduces the amount of system mem­ory used for disk operations and frees up mem­ory for other system tasks. However, perfor­mance when using Elastic Audio features may decrease.
Normal Is the optimum Cache Size for most ses­sions.
Plug-in Streaming Buffer Size
(Structure Plug-in Only)
This setting appears in the Playback Engine dia­log only if Structure, Structure LE, or Structure Free is installed on your system. The Plug-in Streaming Buffer Size determines the amount of memory DAE allocates for streaming playback from disk with the Structure plug-in. This setting only affects playback if disk stream­ing is activated in Structure’s plug-in controls (see the Structure Plug-in Guide for more informa- tion).
Large Improves performance when using Elastic Audio features, but it also decreases the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Cache Size leaves less system memory for other tasks. The default setting of Normal is recommended unless you are encountering -9500 (“Cache too small”) errors.
To change the Cache Size:
1 Choose Setup > Playback Engine.
2 From the Cache Size pop-up menu, select a
disk cache size.
3 Click OK.
The optimum Plug-in Streaming Buffer Size for most sessions is 250 ms (Level 2).
• Plug-in Streaming Buffer Size settings lower than 250 msec (Level 2) reduce the amount of system memory used for sample playback and frees up memory for other system tasks. How­ever, audio quality of sample playback may decrease.
• Plug-in Streaming Buffer Size settings higher than 250 msec (Level 2) improve the audio quality of sample playback, but they also de­crease the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Plug-in Streaming Buffer Size leaves less system memory for other tasks. The default setting of 250 ms (Level 2) is recommended unless you are experiencing problems with the audio quality of sample playback.
To change the Plug-in Streaming Buffer Size:
1 Choose Setup > Playback Engine.
2 From the Plug-in Streaming Buffer Size pop-up
menu, select a buffer size.
3 Click OK.

To hear audio from Pro Tools, you will need to connect a set of speakers or a pair of headphones to Eleven Rack. Sound from Pro Tools cannot be played through your computer’s speakers or your computer’s sound output.
Connecting the Main Outputs
The Main outputs on the back of Eleven Rack are male XLR connectors. To listen to audio coming from Eleven Rack, these outputs should be con­nected to a set of monitor speakers (self-powered or with an external amplifier) or a mixer or monitor controller system.
Main outputs Left and Right output the audio that is routed to the Main Out L/R output path within Pro Tools.
Main output volume (higher or lower) by changing the setting in User Options Mode. For more details, see “Headphone Volume” on page 94.

Analog Audio Inputs

Eleven Rack features three types of analog in­puts. There is a dedicated guitar (instrument­level) input, a stereo line input, and a mic-level input. Choose the input type that fits the signal you want to send to Pro Tools.
Connecting Your Guitar
Use the Guitar input for instruments such as electric guitar or electric ba ss t hat usu ally have a lower level of output than line level instru­ments.
The signal coming out of the Main outputs is at line level (+4 dbu). Take care to use line-level (not mic-level) inputs when con­necting Eleven Rack to a mixer.
Connecting a Pair of Headphones
On the front panel of the Eleven Rack is a 1/4-inch jack to connect a pair of headphones.
sThe Phones jack outputs the audio that is
routed to the Main Out L/R output path within Pro Tools.
Setting Monitor Volume
The Volume knob on the front of Eleven Rack adjusts the output volume of the Main outputs and the Headphone Outs simultaneously. You can offset the Headphone volume from the

Digital Audio Input and Output

Eleven Rack provides digital inputs and outputs for AES/EBU and S/PDIF format digital audio de­vices. You can use these connections to record from digital sources, use external digital effects, or send Pro Tools audio to an external digital re­corder.
Eleven Rack can have devices connected to both the AES/EBU and S/PDIF ports simul­taneously, but only one format of device can be used at one time. You can switch be­tween these two formats from within Pro Tools LE, or from the front panel of Eleven Rack, if using it as a standalone processor.
Chapter 8: Eleven Rack Studio Setup 69
To connect a digital device to Eleven Rack, do one
MIDI In
MIDI Out
of the following:
• Connect the AES/EBU output on the device to the AES/EBU input on Eleven Rack, and the device’s AES/EBU input to Eleven Rack’s AES/EBU output, with two AES/EBU-format XLR cables.
– or –
• Connect the S/PDIF output on the device to the S/PDIF input on Eleven Rack, and the de­vice’s S/PDIF input to Eleven Rack’s S/PDIF output port, using two 75-ohm coaxial cables with male RCA connectors on both ends.
At this point, you can try to record some signal from the digital device (if it is a sound source, like a keyboard or CD player), inserting it onto a pre-recorded track (if it’s an effects processor), and so on.
If you get no signal or a compromised signal, double-check that Pro Tools and your exter­nal device are set to the same sample rate and digital I/O format, and that Pro Tools is set to receive sync from the external device.

MIDI Connections

Configuring Digital Devices
When connecting to external gear digitally, Eleven Rack and Pro Tools must be set to the same sample rate and digital format as your dig­ital device. Pro Tools must also be set to clock from the digital device, or no audio can pass be­tween them.

Recording Guitars

Input selector
Record-enable button
The simplest way to record guitar with Eleven Rack is to simply plug in your guitar, cre­ate a track in Pro Tools, and record the sound coming from the Rig.
Recording Wet and Dry Signals
The Guitar Input on Eleven Rack shows up in Pro Tools as a standard mono input path (Guitar In). This input passes the guitar signal, unpro­cessed, to Pro Tools, where it can be recorded as normal.
To record guitar through the Rig to a track in Pro Tools:
1 Click on the Track menu in Pro Tools and se-
lect New.
2 In the New Tracks dialog, create one stereo au-
dio track.
3 Assign the input on the stereo track you’ve
created to Interface > Eleven Rig L/R.
4 Record-enable the track.
5 Select a Rig in the Eleven Rack Control win-
dow, and tweak its settings, if necessary.
6 Press Record, then Play, in the Pro Tools trans-
port.
7 Record your guitar part.
The guitar signal also passes through the pro­cessing features of Eleven Rack, and the pro­cessed stereo output from the amp, cabinet, mic and effects simulations shows up as a second, stereo input path in Pro Tools for monitoring and/or recording (Eleven Rig L and R). Thus, the dry guitar signal and the output of the Rig can be recorded onto separate tracks, for processing and editing flexibility.
This means that when recording guitars with Eleven Rack, you can decide on a tone you enjoy and record your parts, but retain a clean version of those parts as well. Later, if you decide you want a different sound, or simply want to stack different tones on top of one another, you can re-amp those original, unaffected guitar tracks through a different set of Rig characteristics on Eleven Rack, or even another external guitar setup.
For information on the re-amping process, “Re-Amping” on page 86.
To record wet and dry versions of a guitar part simultaneously for future re-amping:
1 Click on the Track menu in Pro Tools and
select New.
2 In the New Tracks dialog, do one of the
following:
• Create one mono audio track
– or –
• Create one stereo audio track.
3 Assign the input on the mono track you’ve
created to Interface > Guitar In.
Chapter 9: Eleven Rack with Pro Tools 83
4 Assign the input on the stereo track you’ve
Indicator icon
created to Interface > Eleven Rig L/R.
5 Record-enable the two tracks.
6 Select a Rig in the Eleven Rack Control win-
dow, and tweak its settings, if necessary.
7 Press Record, then Play, in the Pro Tools trans-
port.
8 Record your guitar part.
If you don’t plan to use the dry signal right away, you can make the mono track inactive and hide it, using the functions of the Tracks pane in the Edit window.
The dry track will be hidden and will not play, but Pro Tools will retain the data for later use. You can access the track again at any time.
The Guitar In input signal will look quite low when compared to other recorded sig­nals in Pro Tools. If you need to do intricate rhythmic editing, you may want to increase the vertical zoom level in the Edit window.
To embed Rig settings in recorded audio:
1 Open the Eleven Rack Control window.
2 Click the User Options button. The Embed Set-
ting From menu appears.
3 Set the Embed Setting From menu to the input
you plan to record through, such as
Eleven Rig L/R.
4 Create an audio track, and set its input to the
input you’ve chosen, using the Input selector.
5 Record enable the track.
6 Record your part.
The settings of the currently loaded Rig will be embedded in each audio region that is recorded from the input you select in the Embed Setting From menu.
This same method applies when using Eleven Rack with Pro Tools|HD or M-Pow­ered system.

Embedding Rig Settings in Audio Regions

Despite the fact that we designed Eleven Rack to store Rig settings to your computer and to its in­ternal memory, we felt there had to be a better way to keep track of which Rig settings you use as you track your guitar.
Pro Tools lets you embed the current Rig’s set­tings into audio regions as you record them, so that you can retrieve that same setting for fur­ther use later.
This can also be helpful when collaborating or bringing sessions or regions to a different system using Eleven Rack, because your settings travel with the files.
Eleven Rack User Guide84
Audio regions with embedded Rig data are marked with a small guitar pick-shaped icon in both the Edit Window and the Region Browser in Pro Tools.

Re-Amping

Re-Amping is the process of sending pre-re­corded audio (in this case, from within Pro Tools,) to an external guitar amplifier or ef­fects unit, and then re-recording the processed audio to a new track.
This is sometimes done when a guitar track is re­corded dry and the amp and effects sound is to be decided upon later (see “Recording Guitars” on page 83).
In the case of Eleven Rack, re-amping can be done one of two ways.
• Tracks can be sent from Pro Tools into the on­board guitar processor in Eleven Rack, and re­recorded to a new track.
– or –
• Tracks can be sent from Pro Tools, out through the Output To Amp outputs on Eleven Rack, into one or more external guitar amps or processors, and then re-recorded through the microphone, line, or guitar in­puts on Eleven Rack, depending on the type of external devices being used.
To re-amp a signal using the guitar processor in Eleven Rack:
1 Choose the track in Pro Tools to be re-amped
(mono tracks only).
2 Create a send from the track to Interface >
ReAmp L/R.
3 Create a new stereo audio track, and assign its
input to Interface > Eleven Rig L/R.
4 In Pro Tools Edit window, click with the Selec-
tor tool at the beginning of the first audio region on the track to be re-amped.
5 Select a Rig in the Eleven Rack Control win-
dow, and adjust the settings as desired.
6 Start recording in Pro Tools.
7 The audio from the chosen track will be pro-
cessed through Eleven Rack, and re-recorded to the new stereo Audio track.
To re-amp a signal using the Output To Amp outputs on Eleven Rack:
1 Choose the track in Pro Tools to be re-amped.
2 In the Eleven Rack Control window, choose
what point in the signal chain will be fed to one or both of the To Amp outputs using the To Amp Output selectors.
See “Output to Amp Selectors” on page 80 for details.
3 Create a new audio track, and assign its input
to match the device you are using to re-amp, as follows:
• If re-amping through a guitar amp and mi­crophone, or a device with an XLR DI out­put, select Interface > Mic In.
• If re-amping through a guitar-level stomp­box or processor, select Interface > Guitar In.
• If re-amping through a processor with a line-level output, select Interface > Line In-
put L.
4 Set up and connect your chosen external amp
and microphone and/or processor to the Output To Amp 1 (L) output and the appropriate input on Eleven Rack.
• If using the mic input, ensure that the gain and other settings (such as phantom power and pad) are set correctly.
• If using an amplifier and microphone in the same room as your Pro Tools system, be sure to turn off or mute your monitor speakers, to avoid feedback.
5 Record-enable the new mono track.

6 In Pro Tools Edit window, click with the Selec-
tor tool at the beginning of the first audio region on the track to be re-amped.
7 With the Pencil tool, draw a curving line from
the beginning of the track to a point around 10 seconds later.
7 Start recording in Pro Tools.
8 The audio from the selected track is sent out of
Eleven Rack, processed through your amp or processor, and then re-recorded to the new Au­dio track.

Controlling Eleven Rack Parameters with MIDI Data

Using MIDI tracks in Pro Tools, you can record real time changes to your Rig settings, edit them, and play them back to Eleven Rack. This can be quite powerful when re-amping signals through Eleven Rack.
In the following example, you’ll control the Rig Volume parameter in Eleven Rack with MIDI data from Pro Tools.
To control the Rig Volume on Eleven Rack with MIDI CC data from Pro Tools:
1 Create a MIDI track in Pro Tools.
8 Press Play on the Pro Tools transport. You will
see the Rig Volume setting on the Eleven Rack Control window move in time to match the curve you’ve drawn.
This technique can be used for any of the MIDI CC controls Eleven Rack can respond to.
For a full list of MIDI CC data that Eleven Rack can accept, “Eleven Rack MIDI Con­tinuous Controllers” on page 95.
For more information on using MIDI CC data in Pro Tools, see the Pro Tools Refer­ence Guide, which can be accessed from within Pro Tools by selecting Help > Pro Tools Reference Guide.
2 Assign its output to Predefined > Eleven Rack >
channel-1.
3 On Eleven Rack, press and hold the Edit but-
ton for 1 second to enter User Options mode.
4 Scroll with the Scroll wheel to MIDI, and press
the SW1 switch.
5 Use the lit Control knob to choose a MIDI re-
ceive channel. In this example, use channel 1.
6 In the Pro Tools Edit window, select MIDI Vol-
ume in the Track View menu for the MIDI track you’ve created. You’ll see a line running across the track. This is the MIDI CC envelope.

Rig Input
This setting lets you specify which input on Eleven Rack will be routed through the Rig. This can be set any of the analog or digital inputs on Eleven Rack, or the signal sent to the Re-Amp output in Pro Tools LE.
For more information on Re-Amping, see
“Re-Amping” on page 86
Running the mic input through the Rig with your monitor speakers on can result in se­vere feedback, due to the amount of gain available in the amp and effects emula­tions. Be sure to mute or turn down the main outputs before proceeding.
Outputs To Amp
In this page, you can what signal feeds the Out­put To Amp outputs. Turn the Scroll wheel to switch between controlling Output 1 or Output
2. If you want to use the Outputs To Amp in ste­reo, you may want to match the controls for both channels.
Signal
Using the Signal control, you can set what point in the signal path feeds each Output to Amp output:
Rig Input The clean, unprocessed guitar signal, as is present at the input of the Rig.
Amp Input The signal after any processing that occurs before the Amp model in the signal chain.
Amp Output The signal after passing through the amp emulation, but before the cab, mic, and any effects emulations placed after the amp in the signal path.
When feeding signal to a external guitar amplifiers, it is generally preferred to apply no cab and mic emulation to the signal. Since the speaker being driven by the ampli­fier will naturally shape the tone of your signal, using the cab and mic emulations in Eleven Rack will produce compromised results.
Rig Output The fully processed signal, run through every part of the current Rig (including cab and mic emulation).
Rig Out No Cab The fully processed signal, with the Cab model automatically bypassed.
Digital Clock/Input
When Eleven Rack is being used standalone and is not plugged into a computer, it lets you choose the clock source (internal or external), sample rate (if using internal clock), and digital format you want to work with.
Clock Source Lets you choose between the fol­lowing clock sources:
• Int 44.1 kHz (Internal clock)
• Int 48 kHz (Internal clock)
• Int 88.2 kHz (Internal clock)
• Int 96 kHz (Internal clock)
• External
Digital Input Lets you choose the digital format you want to use for input, either AES/EBU, or S/PDIF.
