whatever i do, i can't seem to get any data from an audio input port in
my lv2 plugin. i made local copies of all buffer pointers (even though
that shouldn't be necessary iirc), and in case ardour does in-place
processing, i always cache sample N before writing it to the first
output, so that i still have it available for the other outputs.
i even set lv2:inPlaceBroken, but no luck. now i was beginning to
suspect i'm very very stupid, but then i installed the eg-amp.lv2 plugin
(the simple amplifier example from the lv2core repository, which i've
used as a template for my own code), and hey presto: no signal either.
what the fu..ndamental problem might be, i can't say.
