After more testing...
With pd compiled with "JACK_NUM_PORTS 256", audio runs fine at first, but if the cpu gets a big hit, like when I open a soundfont in [fluid~], the audio falls behind and I get the pops/clicks again. If I compile pd with "JACK_NUM_PORTS 32", this doesn't appear to happen; [fluid~] does its thing, the gui freezes for a couple seconds, but the audio is fine afterwards.
Hopefully this hints at what the problem really is.
no, unfortunately this does not make sense at all.
NUM_JACK_PORTS is only used for sizing arrays properly and setting the
maximum possible numbers of channels Pd can use. as the default number
of channels is still 2, jack should actually not notice anything about
this parameter.
nevertheless, i will re-think....
(but i really need at least 64 channels, most likely more; this was
the main motivation to start writing the entire patch...)
