My 2 cents in this thread. Today I worked on a piece with much legato. It was first searching how to get things the way I want it. I discovered the edit page. By giving attack a number beneath zero (I did the ultimate, -2), the gap between notes is deminished. By increasing the sustain I discovered another way to make the legato more smooth.
Furthermore I used the polyphone legato mode to have the opportunity to overlap tones when needed. The result of one short melody line (just a few notes) I send here. For me this legato is good, perhaps for others not, I don't know of course.
Thank you for sharing this. This mod really makes the Synchron Strings legato sounds it should be!!
