Welcome to Infinity
Pigtronix designed this pedal to be easy to use
yet vastly powerful and deeply musical. Think of it
like 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
for execution of any action with approximately 1
millisecond of latency and high fidelity recording
at 24bits/48kHz. 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 will be able to offload audio from and
upload audio to this pedal, 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
MULTI function which allows Loop 2 to be a length
multiple of Loop 1. This facilitates greater melodic
and harmonic development and frees the
musician from the limits of their initial loop length.
Coupled with the inclusion of SERIES / PARALLEL
loop operation, AUX output for Loop audio and
INPUT SPLIT capacity for recording different
instruments on separate loops, 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 the goals that were initially set out
for this project. It has been an emotional and
psychologically challenging adventure that has
resulted in a product we are exceptionally proud
to present to the world of musicians interested in
loop based music.
This pedal is dedicated to the memory of the
great Les Paul, inventor of multi-track recording.

at the end of Loop 1.

-- QUICK START GUIDE (continued) –

Now Press Loop 1 footswitch to arm Loop 1.
Press Loop 1 footswitch again to open another
overdub on Loop 1.
Press Loop 1 footswitch again to close the new
overdub on Loop 1.
Press the STOP footswitch to halt playback on
both Loops.
Press and Hold the STOP footswitch to erase both
loops.
--
Press the SERIES MODE switch to put the Infinity
into Series mode.
Press Loop 1 footswitch to record (You must
record on Loop 1 first)
Press the Loop 2 footswitch. This will simultaneously
close Loop 1 and begin recording on Loop 2.
Press the Loop 1 footswitch. This will simultaneously
close Loop 2 and begin playback on Loop 1.
Press and Hold the STOP footswitch stop audio
and erase both loops.

Footswitch Functions:
-- FOOTSWITCHES –
The three footswitches are the principal means of
controlling loop actions. The functionality of the
Loop 1 and Loop 2 footswitches is identical.
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.
Loop 1 (PLAY / REC / DUB) –If there is no audio
recorded on a loop, pressing the Loop 1
footswitch will begin recording immediately.
Once the loop is recording, pressing the Loop 1
footswitch 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 will close that overdub layer and
continue playback.
When a loop has been recorded but is stopped,
pressing the Loop 1 footswitch will begin
playback.
Loop 2 (PLAY / REC / DUB) –Functions the same
way as Loop 1 footswitch (see above).

Stop (Hold = Erase) –Pressing the STOP footswitch
will cause playback to cease on one or both
loops, depending on the ARM or ALL setting (see
below). Holding down the STOP footswitch will
cause loop audio to be erased from one or both
loops, depending on the ARM or ALL setting.
-- ARM / ALL –
Quickly Pressing the STOP MODE switch will
choose between ARM and ALL modes.
In ALL, 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, the STOP footswitch will stop playback
only on the loop that is armed. The ARM
functionality also applies to the ERASE command.
With ARM selected, 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 command. Once the loop(s)
is stopped, pressing a loop footswitch will resume
playback on the currently armed loop only.

Toggle Switch Functions:
-- FULL / TRAIL / FADE --
Holding down the STOP MODE switch will choose
the way in which the loops stop when the STOP
footswitch is pressed.
FULL indicates that the audio will stop
immediately when you push the STOP footswitch.
TRAIL indicates that the audio will stop when it
reaches the end of the current loop cycle.
FADE indicates that the audio will steadily
decrease in volume until the end of the current
loop cycle.
All three stop modes obey the ARM setting and
will be applied to the armed loop only in this
mode.
When audio has been recorded on both Loop 1
and Loop 2, TRAIL and FADE stop modes will use
the length of Loop 2 as the master when the ALL
setting is selected.
-- INPUT SPLIT –
When INPUT SPLIT is OFF, both Loops record stereo
audio coming from IN 1 and IN 2
When INPUT SPLIT in ON, Loop 1 gets audio from IN
1 ONLY and Loop 2 gets audio from IN 2 ONLY.

When nothing is plugged into IN 2, then the audio
from IN 1 becomes the source for IN 2. In this
case, the Input Split function allows you to record
separate loops for the left and right output
channels.
-- SERIES / PARALLEL --
When the 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 the 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 down the SYNC MULTI switch will turn
synchronization between Loop1 and Loop 2 ON
and OFF
Once SYNC MULTI is turned on, quickly pressing
the SYNC MULTI switch will cycle through the
SYNC MULTI values.
When the 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 the 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.
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 select a different
multiplier value.
Loop 1 will automatically close once you hit the
maximum allowable length during recording.
Overall recording time for Loop 1 is dependent on
multiplier value you have selected for the current
preset, the size of the memory card you have
