I assume that you don't like the internal effects processors that are included with Cubase SX then??

I use the inbuilt effects in Cubase for reverb/delay/compression/chorus/phase/quadrafuzz etc. quite a lot, although since I got Waves Platinum I tend to use the Waves plug-ins more than Cubase's internal effects.

The voiceprism plus from tc helicon would be exactly what you want however you'd have to get one off ebay i think. I can't seem to find anyone selling them anymore which sucks because I wanted one for myself.

Are there any software programs i can use just for voice effects?

Johnny C you can buy the voiceprism from musiciansadvocate on ebay for new. (i Thought you might like to know.)

I've actually had some solid results running vocals through Amplitube (yes, the guitar plugin) to get the whacky/fuzzed-out/distorted/chorused/phased/flanged/echoed/sounds. As far as SX's native-plugins go, i'm not a huge fan of the 'verbs or choruses but the "DaTube" overdrive can add a nice gritty edge to vocals without muddying up the lyrics too much...
