The Feedback application receives audio from an audio file or an external input (such as a microphone, guitar, or synthesiser) and sends it to 20 different delays, each with their own delay time, volume, and delay time variation setting. The delays are grouped in to 5 different banks, with each bank having it's own compressor, filter, panning, and gain control.

The applications name comes from its main process - the output of each delay is passed through a compressor, then back in to the input stage of the delay, resulting in infinite feedback. This technique allows you to quickly layer sounds over each other, making it perfect for creating dense drones, loops, and textures. As the audio loops in the delay line it gradually loses high frequencies, producing an effect that is similar to tape saturation.

The Feedback application is well suited to live performance, with the majority of parameters controllable via MIDI.
