I just tried, and it seems they get saved fine over here. Looking at the save file format, the interp data is definitely in there. Note how pattr object 'joo2' its interpolation was left to linear mode and is not saved, the rest is.

"box" : { "maxclass" : "newobj", "varname" : "u607008823", "text" : "pattrstorage", "numinlets" : 1, "fontsize" : 10.0, "numoutlets" : 1, "outlettype" : [ "" ], "patching_rect" : [ 330.0, 130.0, 64.0, 18.0 ], "id" : "obj-1", "fontname" : "Arial", "interp" : { "joo" : [ 0, 0.0 ], "joo3" : [ 2, 4.0 ] }, "saved_object_attributes" : { "client_rect" : [ 100, 100, 500, 600 ], "storage_rect" : [ 200, 200, 800, 500 ] } }

yes, well once again, if I make a small test patch on the side it does work indeed, but not in my big patch with hundreds of objects to restore...

btw, I think your code is incomplete (this is not copy compressed from max 5, is it ?), cannot do anything with it - copy & paste in max does not work.

thanks anyway

Yup, that code is not complete, I just copied a little bit of patcher to show that the info is indeed in there.

Try to find the pattrstorage object if you open your patch as text, and see whether the interps are in there.

Debugging big patches is always a lot more difficult than with small patches, because the amount of mistakes you could have made so far increases exponentially. There have been problems in Max where things ceased to work correctly when load increased, but not many. Maybe try to make a small example and then copy objects until you have a few hundred?
