Good stuff to finally hear his voix.C is like a channel strip for the singer (guitarist). In addition there is a harmonization of one or two voices that are guided by the scratch or edited by you.
The sound is good, and I advise everybody to learn about this machine before going on stage without a good sound engineer, a scale, and a sound system of ine of the name.
It's a Swiss Army knife for everyone singer and in addition there's alignment, which though used sparingly gives good singers (see for a vocalist only a very good set of voice).

brief is not simple adjustments tedious (voice live etc. ...), no transformation of voice, no special effects, just a voice coming out of the 'mix', and it is like that.

A good price for a good quality material, it is not every day.

Try it!
