Re: \unset with modified default properties

[Saul Tobin]

Unfortunately, for my use case, \once\set and \once\unset aren't enough.

While not a completely general solution, you may be able to use \once:

%%%%
   music = \relative c' {
     \tuplet 3/2 {
       c8 c c d d d e e e f f f |
     }
     \once \set Staff.tupletSpannerDuration = #(ly:make-moment 1/2)
     \tuplet 3/2 {
       c8 c c d d d e e e f f f |
     }
     \tuplet 3/2 {
       c8 c c d d d e e e f f f |
     }
   }
%%%%
