Some good software multi FX plugins

[John Burgess]

Hi I am looking around for some good multi fx software, used as plugins for ableton live, to be used live.

I have looked at things like Amplitube and Guitar Rig, however I am not really looking for amp or cabinet models, mainly looking for drastically altered tones. Things like pitch shifters, synths, harmonisers, chorus, overdrive etc.

Thanks

Also looking for some pitch to midi converter plugins. I have tried out widisoft's VST plugin, however it doesn't work too well. Also tried bitscrew's pitch a bitch plugin. It works much better, however seems to be windows only. I need mac and windows.
