Electronic Audio Experiments / Mirror House Dissonance Pitch Shifter I purchased this new last month and have hardly used it. It's in like-new condition. The following is a quote from the distributor: Mirror House is a very unique pitch shifter with a one-of-a-kind worldview. It was created in collaboration with EAE and the American alternative rock band "Pile," who are good friends. It creates two "doppelgangers" from the input signal, mirroring each other, and applies equal and opposite pitch shifts to separate them. This approach, completely different from typical pitch shifter devices, called "DIAMETRIC PITCH SHIFT," allows you to freely manipulate strange detuning, parallel harmonies, mesmerizing microtonal clusters, and, if you delve deeper, even ugly but beautiful dissonances. With three modes and simple yet profound controls, everything is designed to intentionally deviate from the established musical aesthetics that abound. Mirror House creates "perfect misalignment" and paints a new landscape on the border between harmony and madness.
