I need to set a passage for piano which consists of an extended melisma all of whose notes tie to a chord at the end. As using actual ties would become an illegible mess, the composer wrote a laissez vibrer after each note, and then short "pickup" ties in front of the chord. I can't see any obvious way to write these, other than writing each as a tie from the original note and then shortening them all with a shape for each one - which would be tedious, messy, and non-robust (as the parameters would need to be adjusted every time the layout of the score was adjusted).
Is there a better way? Paul
