Hi All,
I have this patch, for selecting different sounds and mixing them for listening to result in terms of orchestral timbre:
It gives me a strange phenomenon: when I reopen OpenMusic I receive this error:

To restore or not the file is not useful.
So I must open the patch with textedit and subtitute all ‘#<’ into ‘<’, save the patch and in this way I can reopen it without errors.
I must do it everytime I reopen the patch.
I suppose the error should be into Multi-Item-List class, but I can not be able to understand why.
If useful I enclose the patch, I am on MacBook Pro mid 2012, OsX High Sierra 10.13.6, last version of OpenMusic.
The same happens on Linux, Fedora 32, last OM version.
