After doing a search inside Kore 2, i have found that a patch list wouldn't help you find the 'ooh' sounds that you're looking for... Because there arn't any inside any Cakewalk Synths/Samplers(!)
Plenty of 'aah's, but not a single 'ooh.'
There's some inside Kontakt 4, which may be included in the sounds that you get with the free Kontakt Player that you can download from Native Instruments. There's nothing else from NI either. Can you believe that - you get 10,000 sounds when you buy Komplete 7, but only 2 of them are female O vowels. Alto, or Soprano.
On a side note, i agree with AT, and suggest that for synth sounds, a patch listing would be pretty much useless. By that i mean that you could want a certain bass sound, so you find one by name that works ok - but there's proberly a better fitting sound that has some weird name that you'd never connect it that sound.
Cakewalk's Sound Centre is a big a step in the right direction, but obviously needs further development to allow us to add and 'tag' our own sounds, and include more than just Dim Pro and Rapture in it's included sounds.
Cakewalk Sound Centre is very very simular to Kore 2, but Kore 2 allows you to add and tag your own sounds, it features a much more indepth browser for finding sounds, and you can create 8 different versions of a sound (or 8 completly different sounds) and morph between them. And it's not a simple crossfade that raises and lowers volume, it changes the parmeters of the synth.
You can use it as a host aswell. If you make electronic music and/or use a lot of synths, i honestly cannot recommend Kore 2 enough - not just for the browser function, but for everything else it has to offer.
P.S. I don't work for NI BTW, i just really like Kore 2 because it's speeded up my workflow so much.
