hi,

this really depends on the way the variables
holding the conditions are declared.

to be different for each instance,
they must in the object structure like :

typedef struct _cooled
{
    t_object x_obj;

    t_float x_readpos;             /* data's playing position                                   */
    t_int x_writepos;              /* data's recording position                                 */
    .....
}

pd is not faulty here, i'm certain.

cheers,

Thanks Miller,

I did not explian my problem concisely. I have a PD external (in C) which 
has a struct which contains the starting condisions of the system. These 
variables are set in the lorenz_new method. Then each invocation of the 
"lorenz" method actually calculates one interation of the algorithm. My 
problem is that when I have more than one object the construction of the 
second instance of the object reset the conditions of *both* instances. 
How do give two instances of the same PD external different data-spaces? 

I'll send my ocde if I'm not being clear enough.

Thanks

Hi Ben,

Just back from vacation, trying to get back in the swing now...

Are you having trouble because "sends" and "receives" are talking between the
instances or something like that?  If so, use "send $0-your-name-here" and
it will expand to a private name for each instance.  (table, value, and other
things that use names should all work the same way...)

cheers

While I'm thanking you I might as well ask a question. I've just 
implemented the "lorenz attractor" as a PD external, but I seem to only 
be able to have one instance of it, they interfere with one and other. Is 
the struct (dataspace) of an external shared across instances? If so how 
can I make a seperate dataspace for each instance? 

I'm teaching a little PD workshop at Interaccess (www.interaccess.org) in 
about a months time. Hoping to convert a few of those MAX users. ;)

Hope your vacation is going well (if you still on it?)
