BOSS Vocal Harmonist VE-2

Beautiful harmonies are automatically generated in accordance with guitar chord progressions, and support is also provided for key changes and non-diatonic chords. Manual key setting allows solo vocalists who do not play instruments to use the harmony function. A hybrid mode is used that uses manual key setting as the basis, but also generates harmonies in response to chord input. 24 types of harmony effects are included (12 basic harmony types each with variations). Driven (phantom power supply also possible), it is ideal for street performances.
