1. Welcome to Infinity
Pigtronix designed this pedal to be easy to use, yet vastly powerful and deeply musical. Think of it as a foot-operated, digital version of a multi-track tape recorder. Eschewing the quantization and delayed commands found in other looper pedals, the Pigtronix approach is to make all commands instantaneous. The incredible processing power available in this pedal allows any action to be executed with approximately 1 millisecond of latency and high fidelity recording at 24 bits/48 kHz. It is a mirror of musical reality... what you put in is what you get out.
All loop audio on the Infinity Looper is stored to an on-board memory card and can be accessed via the USB port located on the front of the unit. With the easy-to-use computer application that comes pre-installed on the Infinity Looper pedal, you’ll be able to offload audio from−and upload audio to−this p edal, via a PC or MAC computer.
Complementing the state-of-the-art digital platform of the Infinity Looper is a beautifully executed analog input and output section that provides transparent pass-through audio as well as superior headroom and discreet transistor-based limiting circuitry to prevent digital distortion, even at extreme signal levels.
To put it succinctly, this looper sounds great ! It will not ruin your tone like so many other looper pedals that have come before.
Of all the innovative features found in the Infinity Looper, perhaps the most notable is the Sync Multi­function, which allows Loop 2 to be a multiple length of Loop 1. This facilitates greater melodic and harmonic development and frees the musician from the limits of their initial loop length. Along with the inclusion of Series and Parallel loop operation, Auxiliary Output for loop audio, Input Split capacity for recording different instruments on separate loops, Reverse, Undo, Redo, Loop Aging and Varispeed, the Infinity Looper presets a near limitless set of possibilities for the creative musician.
The Infinity Looper was many years in the making and required a great deal of time and resources to accomplish its ambitious goals. It’s b een an emotional and psychologically challenging adventure that resulted in a product we are exceptionally proud to present to the world of musicians interested in creating loop-based music.
This p edal is dedicated to the memory of the great Les Paul, inventor of multi-track recording.

2. Anatomy and Functions

2.1 Footswitches

Loop 1

This footswitch controls the looping actions for Loop 1.
Pressing the Loop 1 footswitch at any time will arm Loop 1, illumi­nating the corresponding red LED and indicating that Loop 1 is ready to receive Play, Stop, Overdub and Undo commands. Loop 1 is armed by default upon power up.
If there is no audio recorded on Loop 1, pressing the Loop 1 footswitch will begin recording immediately. Once the loop is recording, pressing the Loop 1 footswitch again will close the loop and begin playback.
During playback, pressing the Loop 1 footswitch will open an overdub layer on Loop 1. Once an overdub is recording, pressing the Loop 1 footswitch again will close that overdub layer and continue playback. When a loop has been recorded but is stopped, pressing the Loop 1 footswitch will resume playback from the beginning of the loop.

Loop 2

This footswitch controls the looping actions for Loop 2, and functions the same way as the Loop 1 footswitch (see above).
8
CHAPTER 2. ANATOMY AND FUNCTIONS 9
Stop
Quickly pressing the Stop footswitch will stop audio playback on one or both loops, depending on the Arm/All setting (see below).
Holding down the Stop footswitch for at least two seconds will cause loop audio to be erased from one or both loops, depending on the Arm/All setting.

2.2 Toggle Switches

Stop Mode

Quickly pressing the Stop Mode switch will toggle between Arm and All modes.
Holding down the Stop Mode switch will toggle between Full, Trail and Fade modes.

Arm, All

In All mode, the Stop footswitch will stop playback on both loops. The All functionality also applies to the erase command. With ALL selected, holding down the Stop footswitch will erase both loops. The All functionality also applies to the Play command. Once the loops are stopped, hitting either loop footswitch will resume playback on both loops.
In Arm mode, the Stop footswitch will stop playback only on the armed loop. The arm functionality also applies to the erase command. In Arm mode, holding down the Stop footswitch will erase only the armed loop (to stop both loops in Arm mode, hit the Stop footswitch
twice within 1 second). The Arm functionality also applies to the Play
CHAPTER 2. ANATOMY AND FUNCTIONS 10
command. When loops are stopped, pressing a loop footswitch will only resume playback of the currently armed loop.
Some Remote Switch functions (page 34) also follow the Arm/All setting.
Many MIDI CC/Note messages contain values that also specify Arm or All control. For more information please see the description of the MIDI implementation on page 43.
Full, Trail, Fade
In Full mode, audio will stop immediately when you push the Stop footswitch.
In Trail mode, pressing the Stop footswitch will stop the loop audio when it reaches the end of the current loop cycle.
In Fade mode, pressing the Stop footswitch will steadily decrease the loop audio in volume until the end of the current loop cycle.
All three Stop modes obey the Arm/All setting.
In All mode, when audio has been recorded on both Loop 1 and Loop 2, Trail and Fade modes will be applied to the length of Loop 2.
Input Split
When Input Split is off, both loops record stereo audio coming from Inputs 1 and 2.
When Input Split in on, Loop 1 gets audio from Input 1 only and Loop 2 gets audio from Input 2 only.
For more options and details, see the Infinity Rules Input Split section on page 24.
CHAPTER 2. ANATOMY AND FUNCTIONS 11
Series Loops
When Series Loops is on, you are in Series mode. This means that only one of the two loops can play at any given time. This is handy for verse/chorus-type song structures.
When Series Loops is off, you are in Parallel mode. This means that Loop 1 and Loop 2 can play together at the same time.
Sync Multi
Holding the Sync Multi switch will toggle Sync Multi on or off.
Quickly pressing the Sync Multi switch once Sync Multi is on, cycles
through the sync multiplier factor.
When Sync Multi is off, none of the sync multi lights are lit. In this mode, the lengths of the two loops are unrelated and playback is not synchronized.
When Sync Multi is on, the lengths of the two loops are synchronized. The length of Loop 2 will be a multiple of the length of Loop 1, as set by the multiplier factor indicated by the LED bar to the right of the sync multi switch.
Loop 1 sets the initial length. Once recording on Loop 2 is initiated, the Arm light will blink and it will wait to begin recording until the top of the next loop cycle. Loop 2 will automatically stop recording and begin playback when the proper length multiple has been reached.
You can alter the synchronization at any time while recording, by manually closing Loop 2 with the Loop 2 footswitch. This will cause Loop 2 to close at the end of the current loop cycle. The arm light will blink to indicate that Loop 2 is about to close. To cancel this op­eration, hit the Loop 2 footswitch again and it will continue recording until the full multiplier factor has been reached.
CHAPTER 2. ANATOMY AND FUNCTIONS 12
Once Loop 2 is recorded, the Sync is locked to the multiplier you have selected. It is possible to turn Sync on and off at this point, but you must delete Loop 2 if you want to switch to a different multiplier value.
Once Loop 2 is recorded, its length is fixed. However, turning Sync off after that point allows you to start playback of Loop 2 at any time, not just at the start of Loop 1. Keeping Sync Multi on means that Loop 2 will always replay from the start Loop 1.
During recording, whichever loop is armed will automatically close once you hit the maximum allowable length. Overall recording time for Loop 1 is dependent on the multiplier value you’ve selected for the current preset, the size of the memory card you have installed in your Infinity Looper, and the number of preset slots you have assigned using the PC or MAC application. See the table on page 52 for maximum recording times based on these factors.

2.3 Knobs

Master Volume

This knob functions as a stereo output control, determining the output level of both loop audio and pass-through audio.
When turned fully clockwise, the Master Volume knob provides an overall boost of approximately 3dB.
Setting it at around 3 o’clock gives you unity gain.
CHAPTER 2. ANATOMY AND FUNCTIONS 13
Preset
This is a rotary push button encoder that is used to select what loop preset is in use, and to store loop audio.
The Infinity Looper allows you to store and recall up to 50 presets, which consist of audio that you’ve either recorded on the Infinity, or audio you’ve loaded onto the pedal from your computer using the app. Each preset includes a Loop 1, and a Loop 2 if you’ve recorded one.
For full instructions on how to Load, Save and Copy presets, please see the Infinity Rules preset sections, page 25.
Loop Volume 1
Sets the Loop 1 output volume.
Loop Volume 2
Sets the Loop 2 output volume.
The Loop 1 and Loop 2 Volume knobs are calibrated so that 12 o’clock is unity gain for Loop audio. Turning either of the Loop Volume knobs
above 12 o’clock will result in Loop Audio that is actually louder than the input signal.
However, when recording Overdubs, the Infinity keeps track of the Maximum input level and will decrease the signal level of the Overdub and previous recordings if the increased Loop Volume level would result in distortion.
Loop volume can also be controlled via expression pedal (see Expres­sion Pedal Functions, page 39)
CHAPTER 2. ANATOMY AND FUNCTIONS 14
2.4 Jacks

DC Power

Use only the 18-Volt, 300mA, negative-tip power supply that came with your Pigtronix Infinity Looper. Using the wrong power supply is likely to result in a damaged pedal.

In 1

Looper input 1. This is normally the input to use, unless you are using both inputs for stereo or two instruments.

In 2

Looper input 2. Use this input for the second input of a stereo signal, or a second instrument using Input Split. When nothing is connected to Input 2, the signal from Input 1 is automatically passed to Input 2.

Out 1

Main pass-through/loop output, uses a standard (TS) 1/4 instrument cable. Amp, mixer, or DI goes here.

Out 2

Second pass-through/loop output, for use when you’re using stereo inputs, or two instruments, or want to split your output signal (one to an amp, one to a recording unit, for example).
CHAPTER 2. ANATOMY AND FUNCTIONS 15
Aux Out
This output contains summed mono audio of all currently playing loops. This output is primarily intended for use as a loop only monitor send to a drummer, bandmate or FOH mixer.
Undo
Connect a dual momentary remote switch here using a TRS (balanced 1/4”) cable (not an instrument or speaker cable!) to enable Overdub, Undo, Redo, Reverse, and Varispeed.
We recommend the Infinity Remote: www.pigtronix.com/products/ infinity-remote-switch.
For details on how to use the remote switch, please see Remote Switch Functions, page 34.
Expression
This is the TRS (balanced 1/4”) input for an expression pedal that can be used for three different purposes: audio level control of both loops simultaneously, Loop Aging, or Varispeed.
For details on how to use the Expression Pedal, see Expression Pedal Functions, page 39.
MIDI In
This provides a connection for MIDI beat clock sync (slave), or a MIDI controller. Infinity Looper will sync to MIDI whenever a MIDI Beat Clock signal is preset. The Infinity Looper can also be configured to
CHAPTER 2. ANATOMY AND FUNCTIONS 16
obey MIDI Start, Stop and Song Select, as well as CC/Note control over every feature (complete MIDI mapping). To enable this behav­ior, hold down the Multi Sync switch when powering up. For more information and instructions, go to page 43.
USB
This provides a connection to a PC or MAC computer for loading and offloading loop audio, preset management, audio routing configuration and firmware updates. There are no drivers to install−just connect to your computer and you’re good to go. For more information, go to page 49.
When the USB port is connected, the Infinity boots into USB mode and will not function as a looper until the USB is disconnected and the pedal is rebooted. Save any loop data you wish to keep before
plugging the Infinity in via USB.

2.5 LEDs

Loop LEDs

The Loop 1 and Loop 2 footswitch LEDs share the same color coding, and light pattern (for colorblind users).
Green Red Orange Playback Recording Overdub Solid Slow Flicker Quick Flicker
Both Loop 1 and Loop 2 footswitch LEDs are accompanied by a red square Arm LED that indicates which loop is currently armed.
