Expected behaviour of the example below: engrave a d (transpose the c to d). Actual behaviour: engraved an f. Seems to have done both of the transpositions described in the two different tags in the music function (transposed c to d, then to f, or the other way around).\version "2.18.0" myTranspose = #(define-music-function(parser location theMusic) (ly:music?) #{ \tag #'cd { \transpose c d #theMusic } \tag #'df { \transpose d f #theMusic } #}) { \keepWithTag #'cd { \myTranspose { c'1 } } } The problem seems to be only when the tags are inside a music function (if this is not supposed to work, an appropriate error message should be given). The problem seems to be only with transposition; other music I put inside the tags gets filtered as expected.
If you replace #theMusic with $theMusic it works as expected. But I'm sure David can explain you why. Urs _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
