So im sending messages to pd in order to create subpatches that ive already built but that rely on being set up by some loadbangs. For some reason when i create the subpatches by hand the loadbangs trigger but when i create them with messages to pd the loadbangs do not trigger. Anyone experienced this?

Im running pd ext on a thinkpad win 7

yes, i have experienced that.

it's not technically a 'bug' because dynamic patching is un unsupported 'hack' of pd, rather than an actual feature. however, loadbang will not trigger when dynamically patched like that.

a quick workaround is to send a forced loadbang.

attached patch demonstrates this for subpatch usage and also abstraction usage.

http://www.pdpatchrepo.info/hurleur/force-loadbang.zip

you can force a loadbang by sending a message to the subpatch. say the name is [pd subpatch], you can force a loadbang with [loadbang( -> [send pd-subpatch].

In pd-extended you can also use [initbang].
