Hi,

Can anyone please explain how (or give an example of how) these preset saving objects [preset_node] & [preset_hub] work in Pd-l2ork? The help file is like rocket science to me. Am i right in thinking that these objects to the same kind of job as the [sssad] system by Frank Barknecht?

Thanks

Casper

@casper It's a state saving system. So it's similar to [sssad] in that respect.

The benefit of preset_hub is that you can put [preset_node foo] in an abstraction and it will find the [preset_hub foo] in the parent patch automatically.

Additionally, if you want to fully encapsulate the state saving within an abstraction you can also achieve that without $0. Just put preset_hub inside that abstraction and you won't get nameclashes with any preset_hub by the same name in a parent patch.

In short, it is a state saving system that gets rid of the necessity of passing $0 around at all. That, and it doesn't require you to make connections from the relevant object back into an inlet of preset_node. It just works automatically which is a big UX gain.

Also-- in the help patch, click the different buttons of the radio button on the left and you'll see the state being recalled. The symbol box with the symbols "stooges", "problems", etc. is actually inside a gop abstraction. If you open it you'll see it's just a [preset_node test] hooked into a symbol atom box.

Let me know if you have any other questions. I didn't design or implement it but I have a basic idea about how it works.
