[RWP] How do I tell reaVocode which is the modulator and which is the carrier?

[Jes]

I have a voice file on track 1, and a kontakt sample on track 2, and of 
course the vocoder on track 3. However, I can't, no matter what I do, 
get the vocoder effect! I know the tracks are sending to the vocoder 
because I can hear the track's volume increase, so what am I doing 
wrong? I need step-by-step, A B C instructions with this vocoder. Thanks.
