This thread is cold, but I found it while searching for a vocoder the other day. I was trying to get one for free or cheap and I wasn't having any luck with Tal or vocovee or any others for that matter.
THEN, someone mentioned that REAKTOR from NI has a vocoder. I own Komplete 7 and I've used REAKTOR for "The Finger". Well, there isn't much info available on the vocoder in Reaktor, I did find a 4 part video series on Vimeo that was great and extremely complicated.
When i had a minute i opened it up and found it under "Ensemble".
At first i didn't hear anything, but faintly, YES something was happening!
I put reaktor as a vsti in the vocal track fx bin. Then i inserted a midi track and routed it to Reaktor. recorded some notes and looped the region. After playing with the knobs in Reaktor, I got the classic vocoder sound i was looking for.
DAMN!!! I've had it for YEARS and i never knew it! I have many times used Pentagon when this would have been a better fit. I hate and love it when I find out I had something already :s
