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

http://linux.autostatic.com/images/2010-07/vocoder.qtr

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.

Best,
