I admit for free I was surprised how nice of a sound this has. I wish it had more functionality like the ability to auto-create harp "rolls" (or whatever it's called. e.g the stereotypical thing they use on TV show flashbacks), but for free, I'm not complaining. Very well made.
Like most everyone else, I can't imagine ever actually using this in a recording, but it's still worth a download just for the laugh. Every once in awhile if I'm bored/frustrated/whatever, I'll pull this up and go ooh-ow-ah-ayh-eeh ooh-ow-ah-ayh-eeh ooh-ow-ah-ayh-eeh a few times and I'll feel better. :) And really, the vocal emulation is still better than a lot of "serious" synths I've used. I'd love to see these guys do some synth dedicated to serious vocal simulations (choirs etc).
