FEFefeee

FEFefeee is a versatile Max for Live audio effect device that excites a micro-delayed feedback network whenever the audio input signal surpasses a user-defined threshold. The feedback loop can also be frozen and manipulated in real time, allowing for a wide range of experimental possibilities with the incoming audio. It works with any audio signal, including LFOs and impulse responses.
