First think about what you need. I love these melancholic vocals that are just human but also a tiny bit out of this world (alienated). I saw Jan Blomqvist use this on his sets, very subtle and I think it's synced to the midi of the moog also. Its a nice fx and I liked the minor setting but didn't like it enough. It sucks when u overuse it, unless you're looking for that sound. In my case I just need a pretty sweet vocal station that also compresses, EQ and mixes your vocals with a nice harmonizer fx.
This unit didn't cover that (obviously) but just so you know, it's an extra, not a main "vocal station". It processes your vocals a little bit but it's not going to add up to the mix. The midi response was very nice. Also you can set the presets with your octatrack (program change) so track 1 will be preset 1 and track 2 preset 2 and so on... It's very easy to work with, very easy to control and save your own presets. But for my taste a bit limited and like I said more an extra as a complete unit.
