Hi. I randomly found your blog and found this article to be very well written and a fair review. I have now added your blog to my feed burner account so will be kept up to date with your new articles on cane furniture and various other types of indoor furniture – I’ll be back! Thanks, David

Another graphical data-flow app is demoed in a video @ http://www.refractivesoftware.com/videos.html . This app runs on a local machine using the GPU for rendering rather running in the web-browser.

One more less-is-less example that I think is a poignant ‘tape’ piece by Brian Belet called “Name Droppings”. The piece is a critique of the vita/resume/bio process.

So often these pages or paragraphs are all so much filler and fluff to mask who we really are and what we’ve really (not) done!

Hi Tim, thanks for this post. I like that you use the term “expressive”. Sometimes, live electronics performers manage to be quite expressive and to “hide” some of their set-up (at least the audience does not focus on the “electronics”): electric guitar players (in many different contexts) are good at both.

Comment on Custom Data-Types in Max Part 3: Binding to Symbols by Leigh Hunt

Hi Timothy,
Quick update, for the sake of other people looking over these pages, silly me was storing a pointer to the object’s box, rather than a pointer to the object… not surprising that I couldn’t get my attribute from the looked-up pointer.
Everything works great now. Thanks again
Leigh

Hi again Timothy, Regrettably not 100% clear.... ho hum on me!... Am I storing correctly the object pointer here?.... note - tempbuf is a char array made from obj name/patcher name. eg ::trk1::auxvol[1]

t_object *b;
b = (t_object *)gensym("#B")->s_thing; 
t_hashtab *tab;
tab = (t_hashtab*)gensym("leighsobjecttable")->s_thing;
hashtab_store(tab, gensym(tempbuf), (t_object *)b);

Or is it my lookup that is incorrect?.....

t_object  *t;
t_hashtab *tab;
long n; 
t_symbol *test; (is passed name of key - rg ::trk1::auxvol[1])
tab = (t_hashtab*)gensym("leighsobjecttable")->s_thing;	
hashtab_lookup(tab, test, &t);								
n = object_attr_getlong(t, gensym("param_value"));

I receive no error message, nor the long value I am trying to retrieve unfortunately. I have simply replaced a symbol->s-thing object pointer system with these hashtable parts, so I discount any other possible sources of the problem, eg incorrectly formatted char arrays/symbols. When I print out a list of keys from my hashtable object it shows them all as being there, so I'm sure I'm missing something again, either in the storage or the lookup of the object pointer. Many thanks should you get a moment to browse over this. Cheers, Leigh

Hi !
‘ s->s_thing = (t_object*)h; ‘ – I hadn’t come across this method of binding, or at least not knowingly!
Thanks muchly !

A hashtab is a real Max object, meaning that the first member of it's struct is a t_object. So you should be able to safely cast your hashtab pointer to to the s_thing.

t_hashtab* h = hashtab_new(2027); // prime numbers work well for size
t_symbol* s = gensym("foo");

s->s_thing = (t_object*)h;

Of course, blindly assigning to the s_thing as I did here is not safe as detailed in the article above. Cheers!

Hi Timothy,
Thanks for your prompt reply.
Your suggestion makes perfect sense to me. I’d never looked at hashtabs.

I can see how to create an external that contains a hashtab (which I would place one instance of in my main patcher),
I’m a little perplexed as to how to bind the hashtab to a symbol, at least the syntax for doing such a thing. In xcode I tried binding to both the symbol and the s_thing field of a symbol but I get an ‘incompatible pointer type’ error. I guess I am overlooking something.

‘ I’m not really sure what you are doing ‘ – It’s rather complicated to explain, but it is a system for interacting with the Mackie series of control surfaces MCU/XT/C4. I intend to start documenting online soon. I’ll post you a link when this happens if you like.
Currently the development has is tailored to my setup, but once I am done I intend to make a more open version so people can easily incorporate the system into their existing setup, freebie externals of course!

Thanks again for your time, it’s much appreciated. If you are ever in Europe in need of a live sound engineer, then maybe I can repay you for your troubles!
Kind regards,
Leigh
