I am trying to share pattrstorage presets among multiple bpatchers using the autowatch mode but I cannot achieve it. It seems the json file is indeed written upon preset creation but the other instance doesn't seem to load it.

Maybe I should add it was functioning perfectly under Max 4.6...

Platform? Version? You know - the usual....

Max 5.1.2/MacOS X 10.4.11/MacIntel Core 2 Duo 2 x 2.2 GHz

works fine here. I created a .json file, stored a slot in the first bpatcher, recalled the slot in the second.

@bbracken : how have you created the .json file?

Ok, I see the problem. You are asking to autowatch a file that doesn't exist.

"When file watching is enabled, the most recently read or written XML data file will be reloaded automatically if it is modified"

If the file was never written when the second pattrstorage gets instantiated, then it will not know what file to look for. You will probably have to come up with some way to re-initialize the object after you have a real file to autowatch in place.

I'd be pretty darn surprised if it worked in Max 4.6 any differently.

I don't get it. If I create the .json file in one bpatcher, close the patch, reopen it, each pattrstorage loads the presets. Then, shouldn't the autowatch setting make each pattrstorage reload the presets upon writing by the other bpatcher?

How you just described it works fine here.

If I save a preset in the first bpatcher, close the patch, reopen it, save another preset, I can recall it from the second pattrstorage (or vice versa).

If the .json file exists in Max's search path when the pattrstorage object is instantiated, then you will be able to save, write, reload and recall.

If the file doesn't exist when the pattrstorage object is instantiated, then you will need to do something to tell it what file it should be autowatching *after* the file exists.

I proceed exactly the same way but it doesn't work!

Where is the .json file being saved? Does Max have access to this location, ie, is it in Max's search path? Are your permissions set correctly? Sounds like something non-Max related is going on.

The .json file is in the same folder as the bpatcher and the main patch. Should the folder be explicitely in Max's search path too?

If its in the same folder as the main patch, that should be fine, as it gets added to the file search path automatically for that session. What happens when you try saving to a location explicitly in Max's search path?

Have you checked the permissions on that folder? Where is it, is it on your boot drive?

Well, puting all the files into a folder which is explicitely in Max search path doesn't change anything.

My folder is on the boot drive and I have the read/write permissions on that folder.
