⌂ Multiple simultaneous RehearsalMarks, tunable output per score, grace synchronized [obsolete in 2.23]
An alternate engaver for RehearsalMarks with many features, e.g.
- print multiple RehearsalMarks at the same time step, but still support purging of duplicates
- different formatting in different scores resp. instrument parts
- grace note synchronisation for the RehearsalMarks by printing them left of the grace notes
This snippet is obsolete starting from LilyPond version 2.23.14, which introduces the \textMark and \textEndMark commands. There is no restriction similar to rehearsal marks: there can be several text marks at the same moment.
