[chuck-users] OSC reception not working

Do you get anything at all, i.e., do you see LALA? If not maybe you could
add a printout before the while(oe.nextMsg()) loop.

I've fiddled around a little bit with OSC, but just in ChucK and in Java
(using raw UDP). I tried looking a bit at the docs for PD and SC, but I
didn't find anything on OSC right away (I don't know if the OSC acronymn was
well-chosen - you get a lot of hits on "oscillator" when searching on synth
sites). Are you sure that NetAddr().send() and the PureData stuff formats
the OSC message according to "/test, i" properly, aligning the integer,
inserting zeroes and so on? I don't see the ", i" part in the sender, could
it mistake the argument for a float instead, thus needing people to listen
for "/test, f" instead? I'm guessing the senders in PD and SC don't want you
to add the argument type list.

A basic sanity test could be to implement a sender in another ChucK program
and use that to send to your existing listener. You could have some network
config problem maybe.

Just some random guesses.
