Re: Is the slur too close to the top note?

[Valentin Petzel]

Hello Knute,

you if you check out the internals for Slur (also Tie) you'll find that you 
have quite a lot of control over the demerits and penalties used for 
calculating the Slur shape in the details property, as well options like 
height-limit, rate, excentricity and stuff.

This means that many times instead of using shape it can be better to simply 
tweak a small parameter. Sadly there is little documentation for this.
