Mopis got a nice review in the latest issue (nr 98) of
Computer Music, as part of a round up of something like "Top Six Plugins You Might Have Missed." I don't think it is available in most US bookstores/newstands yet, but a UK user was kind enough to pass it along.
Choice quote: "Verdict: It may look simple, but there's more to Mopis than meets the eye. At this price, it's got to be worth considering. Rating: 8 [out of 10]"
Update wait, I forgot the choicest quotes:
"...thick, punchy bass patches of the sort you'd expect to hear from an ARP or Moog clone."
"...some outlandish sounds that'd sound right at home on a Skinny Puppy record..."
