I have been using a little function to provide non-standard tuplet numbers on following tuplets until a \revert:
tupletMinim = \override TupletNumber.text = #(tuplet-number::append-note-wrapper tuplet-number::calc-denominator-text (ly:make-duration 1 0)) This produces a number followed by a minim symbol (I also have a crotchet version). I have now been asked to include a colon between the number and the note (and no other change), but I can't work out how to add it to the function above. Any suggestions? Paul
