Playback slurs or ties

I was wondering how you can make slurs or ties of notes of the same name sound during playback when the song is finished. I have searched everywhere but cannot find it. Many thanks in advance. With kind regards, Fred Veen

Can you specify what you mean by “sound”? Two tied notes would sound (attack) once at the start of the tied notes. Slurred notes would sound (attack) at the start of each note. Am I misunderstanding you?
