Thomas Thanks for your in-depth explanations. They help me understanding lilypond more and more.
Your tips lead me to an absolutely satisfying result: * Use \repeatTie and \laissezVibrer - clean code, comprehensible score * Lyrics without \repeat / \alternative (in fact: not relevant in the context of rehearsal midi output with \unfoldReapeats) * \tweak X-offset #-0.3 \markup \null __ Regards Stephan Am 05.05.2019 um 12:24 schrieb Thomas Morley: > Am Sa., 4.
