It looks to me like the limit of 12 is hard-coded in src/ulib_opsc.cpp,
line 201:
m_inMsgBuffer(CircularBuffer<OscInMsg>(12)),
I raised it to 256 and recompiled and your example worked correctly.
I can definitely see the value of allowing more than 12 addresses on the
same port. I'm not sure the memory impact though.
