Okay, last message for today.
Eventually I could partially reproduce. If I create a stereo Vocoder track =

Vocoder provided I press "monitor" on it. But the output is a wei=
rd mix of vocoded signal and the modifier. If I change modifier and carrier=

not know. Rui?
The reason why you get a mixed signal could be because you use both outputs=
of the Vocoder track. The vocoder LADSPA plugin outputs the dry signal on =
the second output and the vocoded signal on the first output. That's wh=
y I connected the first output of the Vocoder track to both inputs of the V=
ocoder Mix track, like this you have faux-stereo and better control over th=
e output of the Vocoder track.
Ah, this could be the reason. I will re=

Also, when Vocoder does not receive anything, it starts to generate XRUNs, =
so if you close Qtractor while Vocoder is activated, Qtractor will freeze.<=
The more bands you select in the vocoder LADSPA plugin, the more CPU it tak=
es, so bigger chance for xruns. I didn't thoroughly test this setup yet=
so it might be something else.
LADSPA vocoder in JACK Rack has the s=
ame problem. Being already pretty experienced in this regard (hehehe) I can=
say that this is because of an effect which I forgot how is called when th=
e plugin stops receiving the signal but continues to try to process data an=
d starts going into calculations of really small numbers and it triggers a =
software part of your CPU and it uses a lot of resources, these calculation=
s. The developer should find a way to fix this somehow.
