I think I figured it out. It looks like I have to use t_symbol *sym instead of t_symbol sym and the outlet has to be x->outlet_symbol(x- >x_outlet0, &*sym). That seemed to work. The weird problem I am having now it I get an error with the return(void *)x; I get error: Error: return-statement with a value, in function returning 'void'. Now I see return(void *)x; on almost all the external codes so I don't get it. I am also getting an error on the void your_class_setup (void) { part too. Error: a function-definition is not allowed here before '{' token. I am confused. Any help would be apreciated. Thanks, Alain
