Okay, last message for today.
Eventually I could partially reproduce. If I create a stereo Vocoder track
FIRST, then the latter mono carrier and modifier tracks would channel into
Vocoder provided I press "monitor" on it. But the output is a weird mix of
vocoded signal and the modifier. If I change modifier and carrier places -
the signal does not change. Why would track creation matter I do 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 why I
connected the first output of the Vocoder track to both inputs of the
Vocoder Mix track, like this you have faux-stereo and better control over
the output of the Vocoder track.
Also, when Vocoder does not receive anything, it starts to generate XRUNs,
LADSPA vocoder in JACK Rack has the same 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 the plugin stops receiving the
signal but continues to try to process data and 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 calculations. The developer should
find a way to fix this somehow.
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
takes, so bigger chance for xruns. I didn't thoroughly test this setup yet
so it might be something else.
Best,
Jeremy
