So for now I will use this workaround : \version "2.25.8" tempoChange = #(define-music-function (interval endscale thenscale music) (ly:duration? scale? (scale? 1) ly:music?) "Make a gradual tempo change over @var{music}, essentially changing speed after every duration of @var{interval},

Well, I think my code structure is the problem. The way I create parts is with this part generator this way : #(typicalPart 'piccolo piccolo structure) And for *every* part (instrument) it merges my \structure variable (\mark, \tempo, i.e. what every body in the orchestra needs) with the music

Not quite there yet. Now I get : warning: the property 'tempoWholesPerMinute' must be of type 'positive moment with no grace part', ignoring invalid value '#' Le mer. 23 août 2023, à 09 h 45, David Kastrup a écrit : > > Pierre-Luc Gauthier writes: > > > And what do you know : > > > > git diff

I'm not quite sure how to use it correctly yet but I suppose a typical usage would be : \time 6/8 % btw \tempoChange 8 1/2 0 { \skip 2.*4 | } ^ I.e. : To slow down every 8th during 2.*4 to reach (and keep (0)) a tempo half the speed it was. I get inconsistent results either : -

Thank you all very much - yes, I know about potrace, although I haven't used it yet. However, the \image command sounds like more the sort of thing I wanted - just a cheap and dirty method of inserting images to see (roughly) what they might look like. cheers, Alasdair On Wed, 23 Aug 2023 at
