What is the dsp callback? This is new to me, too.
I had a different approach when it comes to building static arrays
that depend on block size. I used three variables in the struct,
x->n, x->array_pointer, and x->is_new_or_resized
Then, example use in perform routine:
if (x->n != n)
x->is_new_or_resized=1;
if (x->is_new_or_resized)
{
x->is_new_or_resized=0;
if (x->array_pointer != NULL)
free(x->array_pointer);
malloc(x->array_pointer, n);
x->n=n;
}
So, you can see the problem. It would be useful to know another way.
