recurring is based on vox’s repeat percussion, originally created by thomas organ to simulate the rapid strumming of stringed instruments. while the original repeat percussion is at the center of recurring, yesterday effects has taken measures to improve and build upon the circuit while still maintaining its original essence. on its own, or in combination with other pedals, the textural sound of recurring lends itself to creating soundscapes that seemingly repeat infinitely and pulsate with life.

recurrent, in the anatomical sense, is defined as "turning back so as to reverse direction". the lfo section of recurring creates a unique reverse sawtooth waveform, resulting in an abrupt full-signal pulse followed by linear decay. qualities of repeating, following, and aliveness can be heard from recurring. five controls rule over the sound of recurring: volume, depth, rate, a tone switch, and a latching footswitch that allows the user to extend the range of rate. its rate parameter can be controlled by expression pedals and lfo-based, active expression controllers.
