hi, what is the problem that (in pd-extended) abbreviated object classes like mtx_+ cannot be instantiated, I have to create mtx_add before. I think this is a known problem, but is there a solution to fix this? also, some of the objects can't be created, but I am not sure why for example mtx_add is one of these. is there a nameclash so that iemmatrix is not loaded by default? mtx_div seems to be an extra problem (can't be loaded). dumpOSC xx is another object that will not be created only with oscx/dumpOSC xx. what's the rule behind that? hans, do you want bugreports for that kind of stuff? are you planning to fix this at all or wait for 0.41? marius.
