I need a good vocoder plugin. Any Ideas?
Tried MDA’s Talkbox yet? It’s the easiest one…

Pretty nice sounding, lots of features, although you wont be able to use the built in synth in Renoise, and it seems a bit CPU heavy.

Old as the hills but still sounds nice, slightly tempremental maybe (you get weird spikes sometimes) and has quite a big latency, but I use it all the time.
IMO, the best VST vocoder I’ve ever used was the Steinberg one included with Cubase VST, unfortunately I can’t get this to work in Renoise because of this:

If you really want the best of the best and wanna give an arm and leg for it, I would recommend the roland vp-330 (1979).

This is also a string-machine (old school vangelis strings used for instance in Blade Runner) and a very cool analog voice emulator (ahhh). No midi (can be installed for another limb)
You also have pedals for this thing to freeze the carrier signal etc, very cool. You can paint very creative textures by using all kinda absurd external carrier and modulation signals. It’s all very warm and analog sounding. It’s very easy to use it for much more then just ‘funny voices’. This thing is alive ^^
There are also a rack version of it (SVC-350) that got additional graphical EQ. But I got the vp-330, and just find it extremely fun to use.
No vst I have tried get even close to this vintage king 
Yeah, tried to get one of those on eBay a few years ago, but some dumbass non-sniping-bidders bloated the price up to around £800. 
The steinberg vocoder from cubase vst is a pretty good approximation of it though.
