[Rwp] Searching for Plugins

[Alex Westphal]

Hello!

Does anyone know plugins that are simmilar to the Hyperprism Plugins 
that are working a view years ago? These had very interresting reverb, 
chorus and pitch effects, but I don't know, where to find these effects. 
The pitch e.G. has also an side effect, when you pitch some audio down, 
it sounds like many more voices and each of them deeper as the other 
ones, like a downwards echo. I hope my explanation was clear enough.
