The Vocalist Live 2 from Digitech is a two-part vocal harmony generating floor pedal, that uses musIQ Harmony Technology for both note detection and harmony generation. The unit analyzes guitar chord progressions in real-time and generates the correct harmony notes, either a third or fifth, above or below the lead vocal.
Most harmonizers function based on the user inputting information into the unit that specifies a single key/scale setting. However, if a song moves out of the selected key, it is very likely that a wrong harmony note will be generated at some point. The Vocalist Live 2, on the other hand, works by analyzing the chords of the performer's guitar along with the vocal, and utilizing real-time processing, always generates correct harmonies, regardless of the overall key structure of the song.
No extensive programming is needed, other than specifying at what intervals above or below the lead vocal the harmonies will be generated. Fine tuning of the output harmonies is possible, along with the ability to compress, EQ and add reverb to the final output. Separate outputs are provided for the guitar and the vocal/harmony/effects output, along with the ability to mix the levels of the main vocal with respect to the harmonies.
Note! It is important that the guitar is properly tuned in order to get the best sounding harmonies. Alternate tunings such as DADGAD are fine, as long as the tuning system used specifies a frequency of 440Hz for A (A440), and it is based on the chromatic scale (12 notes per octave.) Micro-tonal scales are not supported.
