the OSC protocol, not only for sound,
is often used as streaming interface to multimedia programs like Processing, VVVV, Isadora, Flash, Live and for the mac Quartz Composer.
t.m.h.o. It would be extremely useful if ARENA had a OSC output option, preferably with extra heading, lat. & roll parameters, as the quaternions somehow do form an obstacle in easy use.
