Hi Rafael -
YOu can indeed pass messages to outlets or objects bound to symbols from an arbitrary thread, protecting them between a sys_lock() and sys_unlock() call. You can also maintain your own queue of messages between the new thread and the Pd thread - this will be more work but can be made absolutely robust (i.e., not depending on the safety of the sys_lock() mechanism which I _think_ is safe but one can never be certain.

Hi.
I'm developing an external that starts a separate pthread to poll some hardware inputs. When the outputs change, I need to send a message like [34 56( to one of two outlets in the external from my thread.
Do I need to use my own mutex? or the sys_lock(), sys_unlock() calls around the outlet_whatever() calls? or nothing at all, just call outlet_whatever()?
Anyone cares to give a two line explanation of the logic around this?
Thanks!
