The Mooer Pitch Box brings you clean, precise, polyphonic pitch shifting, in a small package. The Pitch Box features 3 modes (Harmony, Pitch Shift and Detune). Harmony mode shifts the pitch and blends it with the original signal, to create the desired harmony. Pitch Shift mode gives you a precisely pitch shifted note, based on the set interval. Detune mode slightly shifts the pitch and mixes it back with the original note; this creates an, almost, chorus-like effect. The Mooer Pitch Box features a 2 Octave up/down pitch range.
