I'm considering adding a vocoder to my rig -- for a whole lot of reasons; not all of which have much to do with robot voice sounds -- but I'm loathe to add another full keyboard. In fact, with the gear I have, there's not really much that I really want/need right now, except maybe for a DX7, CZ-3000 or DS-8. So I'm interested in a rack or module, and the Warp Factory seems to fit the bill.
Does anyone have experience with this? How intelligible is it? I'm thinking of resting it on top of my JX-8P for easy access, so how large is it? I'm looking for something affordable [a friend offered me a Novation Nova that I would certainly have enjoyed, but he wanted more than I could spend], are there other options at about the same price point [I've seen them go on eBay and Craigslist for @ $100-$150].
