I noticed a link to the demo compilation album when I was looking at Vocallective's website. A couple weeks ago, Plogue released chipspeech, a vintage emulator of some speech synthesis chips. It looks and sounds a lot like Aquestone, but with a bit more control. http://www.plogue.com/products/chipspeech/ USD75 for 7 voices, which is insanely cheap next to a vocaloid, haha. I can really imagine this entering the realm of chiptune music!
