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.”
