For those still interested, I've created a template to quickly load up a 
vocoder inside Qtractor. Here's the qtr file:

You need the vocoder LADSPA plugin and you also need to rename the 
session directory for it to work. I've tested the template with recorded 
samples and it's perfectly possible to use the vocoder with already 
recorded tracks.
