Pigtronix Infinity 2 is a stereo looping pedal with two independent loops and a streamlined user interface that has been designed to provide an intuitive musical workflow, right out of the box. The Infinity 2 enables musicians to seamlessly switch between parts, even during initial recording or while overdubbing. This Verse / Chorus type of workflow is further expanded by the ability to delete the loop that is not currently playing—freeing up an open slot for a new loop to be created, without interrupting playback. Nearly all actions taken by the Infinity 2 occur at the loop boundary. This allows the musician to cue an overdub, switch between loops or stop precisely at the end of a loop, without having to worry about hitting the footswitch at precisely the correct time. Simply tell the machine what to do and it will occur at the end of the current loop. This is the general rule of thumb for all commands, with a few exceptions such as instant stop and fade out, which take place immediately when activated. A small push-button switch, located above the left footswitch, allows the user to change the functionality of this footswitch to perform various Stop, Stutter and Octave Shift effects. A TRS remote jack allows these special features to be triggered by an external switch. Undo / Redo functionality can also be assigned to the left footswitch, allowing the musician to remove previous overdubs and add them back as desired. In addition to a dedicated knob for loop Volume, the Infinity 2 also features a Decay knob that causes loop audio to fade out progressively during overdub. With the Decay knob set fully clockwise, the layers pile up at full volume. With the Decay knob set fully counter-clockwise, each overdub lasts for only one loop cycle. With the Decay knob set anywhere in-between those extremes, overdubbing on the Infinity 2 creates constantly evolving loop textures that can be instantly snapped back to a previous state using the Undo function.
