HARMONY Modes The six HARMONY Modes will pitch shift your voice to create 2 to 4 part harmonies along with your dry vocal. The pitch and number of harmonies depends on the selected mode. In addition the exact function of the VOICE MIX and GENDER BENDER knobs changes slightly with each mode. Please Note: All six harmony modes require an instrument to be played along with your vocal to provide the key information for the pitch shifter.

MULTI HARMONY 2: Lower 3rd, Lower 5th, Upper 3rd and Upper Octave The Voice Box creates the same three harmonies as in Multi Harmony 1 and adds the upper octave. The harmonies consist of the lower 3rd harmony, the lower 5th harmony and the upper 3rd harmony. Added to the mix is the upper octave. VOICE MIX knob: Mixes between the lower 3rd harmony (in knob’s LOW position) and the upper octave (in knob’s HIGH position).

VOCODER Mode VOCODER mode turns the Voice Box into a 256 Band vocoder. Vocoding is an effect that allows a voice to modulate an instrument or sound source. The controls have been optimized so that the vocoder is very much plug, play and sing; the musician does not need to do much work to create fantastic sounding vocoder effects. As with most vocoders, both a vocal signal and an instrument signal are required to obtain the proper effect.
