Upper and Lower slurs in \partCombine

[David B. Stocker]

Hello,

The 2.18 manuals seem to indicate that simultaneous slurs are a no-no, but I thought I'd check here to see if anyone knows of a trick I haven't thought of.

In my example, I would like to have a slur below the staff starting and ending in the same place as the slur above the staff. PrhasingSlur doesn't produce the desired result. I've also tried making a slur of a different length - the 1st two notes only - and then using \shape to lengthen the slur and make the arc look more natural.

This method works, but it is cumbersome.

Is there an easy way to do this?

David
