I did an experiment now and replaced netsend with sendOSC/dumpOSC.
They seem to perform much better. I still need to run some more tests,
but it seems I'll use OSC for the performance tomorrow and I won't use
jackd. With some fiddling I managed to get Pd to talk to the USB card
directly ("-noadc" helped a lot) and without jack, the audio-Pd runs
much smoother anyways.
Ciao
