Hi,

I'm running into two issues I can't seem to solve:

1. Is there a way to dynamically load and clear abstractions?
   Let’s say I have multiple synthesizer engines with different GOP settings and sliders.
   I’d like to switch between them by always loading just one engine at a time and replacing the GOP of the previous engine.

2. I’d like to create a virtual display/dynamic GUI. I know that I can’t hide objects in Pure Data, but I could move the GOP to different sections to give the impression of switching display pages.
   The problem is that I have 16 tracks, and each track might need 6–8 pages. That’s already over 100 pages — not including the different synthesizer engines with their own settings for each page.
   Altogether, that could easily add up to 400+ pages, which is way too much to handle just by shifting the GOP.

I also considered using one abstraction per track. But that would require showing a GOP inside another GOP, which looks like that won`t work either?

Are there any other options I could try?

the auto-builder thing puts abstarctions into a subpatch. and it will clear the pd box/ subpatch. this is where I usually look. but they have a few links on this site as well.

these files use abstraction placements and clear them.

@impression Dynamic patching can do all you need, [iemguts/canvasdelete] will be of great use and simplify everything, the iemguts library might have other externals which will be of use to you as well. Using [send] and [receive] and their audio counterparts instead of physical connections is nice when practical, lets you just pass the names to the [send]/[send~]/[throw~]s in the abstraction through its arguments. Previous post has some on dynamic patching and there is a good amount about it on the forum.

Moving the GOP could probably work, pd can handle a surprising amount, just stick a [switch~] inside of any abstraction which does audio rate stuff so you can turn it off and be sure to turn off any message rate stuff in the appropriate way when you hide it.

You can show a gop in a gop, what is not working for you?

ah thanks a lot. I am happy there are multiple option. Will give them a try. Thank you

@oid. I am sorry you are right, GOP inside GOP is working indeed. I think the GOP I created inside the other one was slightly bigger, which is why it didn’t show the whole content, and I assumed it wasn’t working.

@impression If you go the route of moving the GOP, [iemguts/canvasposition] will be of help, stick one in the subpatches/abstractions to get their location as needed so you don't have to track all the GOP positions manually, something like this:
