I just tried this Vocoder out tonight in FL Studio 8.0.2 and it sounds good and was easy to setup.
First I inserted it as a Vsti synth, set the modulator to 'from capture 1', then I go to an insert track and load 'Vocov2Capture', it's already set to 1, then in the same insert I select my soundcards audio inputs (where I'm speaking into a mic) into the 'In' section, go back to the Vsti section and start to play Vocov with my midi keyboard while I'm speaking and get my Mr. Roboto goin' on.
It's a very flexible vocoder with lots of different routing options that are relatively simple to set up for a vocoder (I always struggle setting up vocoders). If you don't want to use Vocov's internal synth, you can route another Vsti to an insert, load 'Vocav2Capture', click on 2, go back to Vocov Vsti select 'carrier-from capture 2', start playing your alternate Vsti while talking into the mic and you're set.
There's your standard fx included Chorus, Delay, Reverb, HP, EQ, Pan, stereo width etc. which is nice, and it also includes what it calls a digital vocode and analog vocode mode which you can adjust to taste.
It's a really nice vocoder that has nice amount of flexibility and ease of use, I'm not sure it's the most computerized robotic voice I've ever heard, or rich, but it still sounds very good and probably can be programmed to have that instant WOW!! factor in the right hands, although I've pretty tickled by it tonight. I've tried a bunch of vocoders recently and this one has put a big smile on my face, it's sure to be in my vst folder a long long time, and it's completely free to boot!! I'm thrilled!
