I tried one out and found that it did not do what I wanted, so I ended up with a TC Electronics Voice Prism. This was a while ago and I believe that the new version may be improved.
eventide effects arent set up as multi effects, patches contain
just reverb or just delay.pitchshifting but you can string them togeather. they are not as user friendly to program. top quality
effects and no boundrys though. i have a tc fireworx.. its
very fast on the fly to program "i love it". i am surprised you
chose the tc voice p. over the orville. the orville has the best
pitchshifting in the recording business. and the reverbs im told
are just as good or better than lexicon
