Just got Voicelive Rack and it works find as stand alone through PA etc. However, I got it to process dry vocals as a plug in. The instructions are on the side of complicated but I found Youtube video on use as an aux send through a mixer. I wanted to use as a plug in. I think the rack can be insert on an aux track in Protools 12 but it gets me confused on how to set it up correctly. You can send a dry vocal to an aux track with the rack as an insert on the track. How to do that is the question. I am experimenting but no luck so far.
