What are some examples of patches with nice preset saving systems?

I’m interested in adding the ability to save presets to a synth patch I’m working on. What are some patches that have systems set up for saving multiple presets from within the patch? I’d love to check out any approaches to this that have been tried in other patches.

Thanks for any ideas!

Just came across the Juno patch while browsing preset solutions and it seems to work pretty well (although strangely doesn’t seem to save the ADSR’s release, but I’m sure that can be fixed).

It’s easy enough to use that I’d be into it being a part of most patches.

Any other preset methods I should consider?
