Antonio,
I am sure your code works. But what I found is that if I change the type from Text to Varchar(max) and simply add NOT NULL, the default of the Text type stays. So, in the end I don't need to set the default.
Thank you.

UPDATE. I believe you are right. I have to "deal" with the constraint. Because when I ALTER the column, the SQL complaints that the field NOTES depends on the constraint. So, I will have to drop the constraint first.
It is never very simple :)
