[pluggo] Saving buffer's contents with preset - weird behaviour on recall

In order to save a curve drawn in a short buffer into a preset, I try  
to save buffer's data using a coll and plugmultiparam.

Globally it works fine but the first sample's value is often not  
correctly recalled.

Any help would be highly appreciated!

#P comment 115 375 366 196617 PROBLEM : sometimes \, 1st sample's  
value is not correctly recalled. It appears to be stored corretly in  
plugconfig but is modified/lost (?) upon preset's recall. I thought  
it was because of uzi but inserting defer should have solved the  
problem.;
