Hi Alexandre,
thats bad news really. this list was the last hope i had. what version of osx are you working on ? are you sure there is nothing im missing ? what else could keep pd from loading up a library ? i dont want to give up on this library.
since Hans-Christoph says xsample is included into PD-extended, it should also be loaded at startup. Do you get the xsample banner in the console (could you post your console output here?). What exactly is not working for you? Are you able to create an [xgroove~] object?
greetings, Thomas
