New Verison Infinity Looper Application

MIDI Sync firmware update beta will be posted shortly (hopefully 4/7/2014)… check back soon.

obviously, this firmware update is taking way longer than anticipated. we apologize.

for now, feel free to download these alternate firmware versions:

vari-speed beta code we showed at NAMM. note: this vari-speed build does not address the minimum loop time issue, which will be eliminated with the upcoming looper update.

This verispeed BETA is really just a test code. The left button of the remote cuts the sample rate in ½ (24kHz) and the right button doubles the sample rate (96KhZ). Hitting both buttons defaults to the standard 48kHz sample rate). Expression pedal changes sample rate continuously across the full range.

By the end of this month, we will have the final firmware that lets everything happen at once. For now, there is no way to combine all these new functions until my engineer delivers the final code, which will offer both rock solid MIDI sync AS WELL AS varispeed and the ability to track tempo and time signature changes in the MIDI clock. It will also have stutter start, 10MS minimum loop time and the ability to change the sample rate by any chosen musical interval.

10ms minimum loop time code

Infinity Firmware to allow sync with Echolution 2 MIDI clock

… hi everyone, we are getting closer to releasing the massive Infinity Looper Vari-Speed (and more) update.

The big news for today, is that we’ve conquered the minimum loop time issue. The new minimum loop time on the Infinity will be in the vicinity of 10ms. Thank GOD! What a relief. NURF is the MAN.

hang tight for this update, it is gonna be amazing.

For now, here is a version of the Looper firmware that resets the MIDI clock counter when you start recording onto the base layer of the first loop. This is essential for using the MIDI out on the new Echolution 2 as your clock source.


MASSIVE firmware update to the Pigtronix Infinity Looper to be unveiled @ Winter NAMM

This INFINITY UPDATE is almost done. It will be released by the end of February. Check back here for the release announcement.
New Infinity Looper Firmware features include:
Vari-Speed (via Expression pedal or MIDI tempo change) – This allows continuous control over the speed of the loop, down to Half Speed or up to Double Speed.Half Speed / Double Speed via remote switch50 Presets (100 loops!!!!)

MIDI clock correction to fix jitter & drift

Echolution 2 MIDI Sync - Resets the MIDI clock counter when you start recording onto the base layer of the first loop. Essentially this lets you define the “1″ while letting the E2 tap tempo or delay time set the MIDI clock.

MIDI CC map to allow remote control of all footswitch functions

Blinking PULSE of DIGIT at beginning of loop cycle

Sum both channels to mono (2 input / 1 output) – implemented by holding down SERIES LOOPS button during startup.

HUGE thanks to NURF and Hemogloben for making this a reality!

Firmware variations

Hi everyone, we’re cranking away on another firmware update, but in the meantime I though it would be cool to make a few alternate versions available.

So here they are:
This one turns x6 sync mode into x16. Keep in mind you can always close early to change the sync value, so x16 is very useful:
This one is the custom firmware we did for Phil Keaggy.

1) RESET Feature

REVERSE switch has been repurposed to do the following:
When RESET is triggered and a loop is playing, the loop is instantly STOPPED (regardless of FULL / TRAIL / FADE), ERASED and made ready to record base layer once again.
RESET applies only to the armed loop.
The loop that has just been reset remains armed.

2) Default settings
On power up, preset “0” will default to SERIES mode with SYNC turned off and FULL active. INPUT SPLIT is off. STOP mode set to ALL

Major Firmware Update for Infinity Looper Announced – Reverse Playback and Phil Keaggy Updates

Pigtronix is proud to announce a major new, free firmware update for the Infinity Looper pedal.To install the update, run the firmware update function from the Infinity Looper Application or grab it from here:

New features included in this update are:

Reverse Playback
Rec –> Overdub –> Play
Trails and Fade STOP override
Instant Clear
Series mode overdub commit
Click Killer option 

Here are the details

1) Reverse mode. It is now possible to reverse a loop. Here are a few things to remember:

- REVERSE is triggered by shorting the RING to the SLEEVE of the UNDO jack. This is accomplished by connecting any two-button, momentary footswitch (such as the BOSS FS-6) to the UNDO jack with a TRS cable. Pigtronix will be manufacturing a dedicated Infinity Remote switch pedal soon.

- Pressing the REVERSE button means that REVERSE playback will be started at the beginning of the next loop cycle. Pressing REVERSE also works during the initial record of a loop.

- Once you are in REVERSE playback, pressing the REVERSE button means that playback will go forwards at the beginning of the next loop cycle.

- Once you are in REVERSE playback, you can use the UNDO switch to flip flop back and forth between forwards and reverse versions of the same layer instantly.

- Hitting REVERSE and then UNDO before the end of the loop cycle will cancel the REVERSE command.

2) Rec –> Overdub –> Play

- In response to numerous customer requests, we have implemented a feature that allows you to go directly from recording the base layer, straight into overdub mode. Once you have started the base layer recording, simply press the UNDO switch to close your initial loop and go straight into playback with overdub active. Press the appropriate Loop footswitch as you normally would to close the overdub when desired and begin regular playback.

3) Trails and Fade STOP override:

- It is now possible to override TRAIL and FADE stop modes by double pressing the STOP switch. This lets you simply leave the unit in TRAIL or FADE mode and retain the option to get a full stop by pressing the STOP footswitch twice in a row. Big thanks to Phil Keaggy for this excellent suggestion!

- Bug fix: Closing a loop initial record in FADE or TRAIL mode is now possible using STOP.

4) Instant Clear:

- When one or both loops are stopped, hitting UNDO will trigger an instant erase of the currently armed loop. This lets you simply leave the unit in ALL mode and retain the option to clear individual loops by pressing the UNDO switch after the desired loop has been stopped. Thanks again to Phil Keaggy for this one!

5) Series mode overdub commit:

- Using TRAIL or FADE, in SERIES mode, overdubs are not lost when switching from one loop to another regardless of whether the current overdub layer is open or closed. Thanks to Charlie DeLauro for this one.

6) Click Killer option

- In the Loop Aging menu (press and hold INPUT SPLIT), an option has been added to disable/enable the loop boundary click killer. If it is on, the menu will show “C”. If it is off, the menu will show “c”. Click Killer defaults to “C” Pressing the encoder while on this option will toggle the loop boundary click killer status. The loop boundary click killer is a super quick crossfade between the beginning and end of a loop. For musicians who want to construct sustained droning loops with overdubs that cross the loop boundary, turning the click killer off with result in “seamless” loops. For more rhythmic and song based performances, we recommend leaving the click killer on.

Thank you to EVERYONE who contributed to this massive update.

Infinity Looper Firmware Update Available – Stability Fix and SERIES mode with TRAILS / FADE

Please run the Infinity Looper firmware update process from the Looper Application TOOLS menu.

If you choose “automatic” the application will grab the update from my website and install it.

Once you do this, power cycle the pedal while holding down the INPUT SPLIT key. The display will show “F” and then reboot once updated.

This is a CRITICAL new firmware that improves Series mode with MIDI and also fixes the “E” crash that would sometimes occur.

This update also implements a new feature:

In SERIES mode, when TRAILS is selected, switching between loops at any time will cue the selected loop to begin playback automatically at the end of the current loop cycle.

Similarly, when FADE is selected, switching between loops at any time will fade the currently playing loop from the time the button is pressed until the end of the current loop cycle AND also cue the newly selected loop to begin playback automatically at the end of the current loop cycle.


Variable Feedback Decay is ACTIVE on Infinity Looper

Hello everyone. As promised, the first of the requested additional features for the Pigtronix Infinity Looper has arrived:

Variable Feedback Decay

We call variable feedback decay “Loop Aging.” Here is how the feature works on the Infinity Looper:

Press and hold INPUT SPLIT for 2 seconds to enter the Loop Aging Menu.

The digit will flash between “A” and “-” indicating that Loop Aging is currently turned off.

Turn the rotary encoder to select the desired Loop Aging value.

1-9 = variable feedback decay. lower number causes loop to decay faster
0 = no feedback, loop is gone after 1 playback cycle (aka loop replace)
P = expression Pedal control of feedback value
- = loop aging is turned off

Press down on the encoder (or push INPUT SPLIT again) to finalize the value you want and exit the Loop Aging menu.


Like everything else on the Infinity, Loop Aging happens in real time, so you can turn loop aging on and off (or adjust it with expression pedal) as much as you want throughout the course of a single loop cycle.

You can enter the Loop Aging menu at any time, even during playback.

Loop Aging settings will be saved when you save your preset.

Feedback decay only takes place when you are in a OVERDUB state. When you are in normal playback, the loop does not decay.

UNDO works as expected, allowing you to UNDO/REDO any loop aging that you let happen during an overdub, no matter how many times you let the loop cycle.

When using expression pedal feedback control, toe = “-” (no feedback decay) and the numbers go down from 9 to 0 as you move towards the heel.

You can use a simple momentary switch (connected via TRS) in place of an expression pedal to get an instant “Loop Replace” function out of the “P” mode since hitting the switch is like going to “0.”

To install Variable Feedback Decay, run the firmware update function from the Infinity Looper Application or grab it from here:
