it's been a while I haven't touched up my Max externals (last time was in 2007 :-) . Now I want to (finally!) move to the new buffer~ API. My question is if one object may have several buffer references. I am asking because I am scheduling many gains in my object, all potentially using different buffers. I assume I need a reference per buffer and I am wondering if buffer_ref_new(), buffer_ref_set() and object_free() are costly calls. I would like/need to perform them on a grain-by-grain basis. May several grains using the same buffer use the same reference? Just to be clear: all the scheduling of the grains is done internally to the object.

Hi fellow developers,

buffer-references

I have sorted things out pretty much by now, but there remains one question at this point: if my objects uses several buffer references, how is the notification process working? Can I determine which buffer has been modified by comparing the void* sender passed in? Would it be the address of the buffer object?

hi, in case you haven't solved the issue already: 

yes, you can query the 'sender' for its buffer name like this:

bufname = (t_symbol *)object_method((t_object*)sender, gensym("getname"));

t_symbol *bufname;
bufname = (t_symbol *)object_method((t_object*)sender, gensym("getname"));
