[PD] dynamic subpatch creation

[Phil Stone]

Hello all,

I'm playing with dynamic object creation, and so far have figured out 
how to dynamically instantiate objects inside a subpatch and connect 
them up.  Now I'm trying to dynamically create subpatches inside of that 
subpatch, and I thought I could do this by sending "canvas...."/ 
"restore..." messages to the subpatch in the appropriate order.  When I 
try this, I crash Pd.  Now, it may be that I'm not forming the messages 
correctly, but before I wander down that potentially-primrose path of 
debugging, I'm wondering if what I'm doing is possible at all.

This is the message I'm trying to send when Pd crashes ($1 contains the 
subpatch's name -- I know this is correct from earlier experiments that 
didn't use canvas/restore):

;
$1 canvas 5 5 362 348 f_instance 0;
$1 obj 29 86 routeOSC /name;
$1 obj 29 111 routeOSC /f /q;
$1 obj 22 160 bp~;
$1 obj 22 195 *~ 0.0002;
$1 obj 22 224 env~ 8192;
$1 obj 22 252 int;
$1 msg 22 278 /fout/lev/name pd-1010-dfb;
$1 connect 1 0 6 0;
$1 connect 2 0 4 0;
$1 connect 4 0 5 0;
$1 connect 5 0 6 1;
$1 connect 5 1 6 2;
$1 connect 6 0 7 0;
$1 connect 7 0 8 0;
$1 connect 8 0 9 0;
$1 connect 9 0 10 0;
$1 connect 10 0 3 0;
$1 restore 127 223 pd f_instance;

So, is it the canvas/restore messages that are crashing Pd, and if so, 
is there some other way to dynamically created subpatches inside another 
subpatch?

Thanks for reading,
