tractor, as a plugin host, is currently accepting only the following
signal flows:
a) audio_fx plugins: audio_in -> plugin -> audio_out
b) instrument plugins: midi_in -> plugin -> audio_out
any other topology is, well, not designated to comply
a vocoder plugin is usually an audio_fx with direct midi control, which
i'm afraid, is not supported ootb-- it doesn't fit in any of the above
categories :(
gosh, there was this indirect solution as inserts but, don't go that
way. it doesn't work, you'll get just silence :S

Rui -- any chance qtractor's "use cases"
can be expanded to fit this
scenario (which seems pretty common).
What about the scenario of a plugin that provides audio in --> MIDI
notes (midi pitchtracker, which is part of what's provided in
autotalent). Is there a way of separately using it for audio->MIDI
input?
besides the crash issue, which should not happen in any circumstance,
life's cruel however, there's no plan going on in that direction.
things can change though, but i will let Paul (i mean ardour3) take the
head on this one ;)

perhaps you should investigate Ardour3 per this reply

the goal is to have ardour 3.0 able to do this by the end of next week, just
FYI.
