You can try for something like \context Timing \applyContext #(lambda (c) (set! (ly:context-property c 'tempoWholesPerMinute) (* 3/2 (ly:context-property c 'tempoWholesPerMinute)))) which is a Midi-only way of doing this. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
