This is a fascinating discussion, and I am amazed by the various and ingenious methods of parameter persistence. In fact, it's a bit of an "embarrassment of riches". I'm in the middle of designing a system for live performance, and need to decide on which approach to take. In particular, I'm very impressed by Frank B.'s work, both on RRADical and sssad.
Frank, could you comment on the difference between these approaches? Do you think RRADical is the way to go for the long run, or is sssad a better path? I'm interested in being able to recreate fairly complex, polyphonic patches of my own design for use in live performance, and I want to be able to control just about all aspects of the sound with live or function-driven inputs (a tricky proposition when combined with polyphony AND persistence).
I'm leaning towards sssad right now, because it has less reliance on
externals, and I'm limited to core PD for the time being (Intel mac).
But RRADical seems to embody a more ambitious and encompassing
philosophy about patching and persistence - do you still see it as viable?

Personally I use RRADical in my patches. It is more powerful and mature compared to [sssad]. Expecially switching between presets on the fly works flawlessly in RRADical, but it's tricky to do with [sssad] and only pure-Pd objects currently. [sssad] however deliberately is kept very simple and small. For example while the core of RRADical/Memento is three abstractions - [commun], [originator] and [careGUI] - [sssad] is just a single abstraction (using some helper patches inside).
So if you're stuck with plain Pd, you cannot use Memento currently, but using [sssad] will make it easy to "upgrade" later. [sssad] is very similar to [commun] and with some search and replace action it is possible to replace one with the other:
All that is needed to convert a sssad abstraction to a RRADical abstraction is this: [sssad $1/ABC] needs to become [commun /ABC $0] and one needs to add an [originator $1 $0], that's all.
In theory the other way around works as well, but of course one looses functionality.
For polyphony a good trick with both Memento and sssad is to use abstractions that share the same $1-tagname. Attached is a little example with sssad.
