Condense slur

[k.k]

This is an instrument that features Condense.

How can I create a sluer like the one shown here?

In galley view, add the slur to the instrument. It is as simple as that.

For the slur to appear, the 1st beat of bar 3 must be condensed in two voices.

You can fake a 1-voice appearance in Engrave Mode if you want:

Flip the bottom eights:

Set their Voice Column index to 0 and adjust the beams so they overlap:

Thanks.
