I have just tried to save some settings of my patch.
A problem of the main patch is that it has only [bpatcher]s or abstracts.
Thus, I am trying now to find a possibility to save and load the presets from the main patch.
drop an [autopattr @autoname 1] into all your bpatchers/patchers. Then drop one of these into the main patch. Then create a pattrstorage object and voila, everything is linked to this one pattrstorage object.
