The Walls OS is one of the softwares mainly used by the Mukatu Guitar's Walls Osc component.
The Walls OS is the centerpiece of the Walls Osc. Its main function include an X-Y pad used to play and manipulate audio signals, such as synthesized sounds, samples, or guitar sounds (in the case of the Mukatu Guitar). It can also play continuous music loops, such as backing tracks, drum patterns or looped samples, as well as effect them. It is no limited to traditional audio signals however, as it can serve as a metronome using the WOS' BPM function.
