What parameter are you saving that needs $0? Since $0 is specific to an instance of a patch, it doesn't really make sense to have it as a parameter value to be saved in a preset. Presets should be loadable in any instance.

Oh, and I do have some fairly complicated uses of these, but the patches aren't quite shareable yet. But almost everything I've done with these is just bigger versions of what's outlined in the helpfile.

Hello people. Just a reminder to check some abstractions for presets management that I've recently posted:

Thank you in advance for the feedback.
