I quite like them. If you want to just use the notation and have it come out in a clean and consistent manner, I think that they are great. I think it is a really big step up from the MuseSounds. If you want all the bells and whistles, get the Kontact version. I dipped my toe in and just got the Solo set and after hearing them, came back and got the full Nucleus. My only complaint is that I would like to have another set of the sections with half sized ensemble.
