I stumbled upon the possibillity to create objects, and abstractions from my library, in subpatches via messages sent to pure data.
They are formatted as the following(x and y are the positon on canvas in subpatch)

[;pd-subpatchname obj x y name-of-object args(

I thought this would be really cool cause it would give me the oppurtunity to make my patches more dynamic. For example making a synth with no fixed number of oscillators, but with the possibility to set the number of oscillators dynamically,(I am thinking especially about communication with vvvv or other software where number of objects in a patch can change dynamically or the possibility of the poly~ object in max).
Now i am stuck with the following problem. When i create a abstraction via a message dsp is not running inside the abstractions. It only starts to work if i delet a random object from the abstraction. Also loadbang seems to be disabled when i use this method for creating objects. Anybody with a little expierence has found a work around for this?

Thanks!!!

ok, last issue first:

when you dynamically create an abstraction or subpatch, you're not really 'loading' it...so you need to trigger your loadbang manually.

basically, you just send a [loadbang( message directly, like:

[loadbang(
|

or

[loadbang(
|

As for the DSP issue, it is well known, and there have been lots of discussions about it. This one might help:

Thank you very much mod!

I spent the afternoon in the forum and was searching the mailing list and came to the following solution that works for me on my windows system( the dsp on off trick won't do it for me cause it takes my system 300ms which of course causes audio dropouts).

When i create an abstraction with dsp objects inside i create an dummy abstraction aferwards which is empty. Then the dsp tree in the first abstraction gets updated and i can dynamically create oscillators without audio drop outs.

I attached a small demostration patch.

The only problem that i see is when dealing with bigger abstractions which contain many dsp objects, cause than, as maelstrom pointed out in the other thread, pd would have to rebuild the dsp graph for every object. At the moment it works for me! I wonder if this will be fixed for any upcoming release cause it seems a wide known problem among pd users.

Thanks!
