I do not care who ever tells me what ever about what he thinks a legato should be or not. I am pretty confindent to get out from that librariy what I want to get. For me there is absolutly no need for any "harsh" opinion.
Just really try to work with the best you can get. And this is exactly the reason why we meet here and not anywhere else 😉.
