Comment #6 on issue 185 by [email protected]: RhythmicStaff squishing chords should produce single notes
http://code.google.com/p/lilypond/issues/detail?id=185
Having the Pitch_squash_engraver do all the work would certainly be more user friendly, though this would deprive the engraver of its elegant simplicity.
As for squashing by voice, I would just have moved the engraver to the Voice level where needed. Forgive my ignorance (as mentioned, I am new to the LilyPond code): how can I elegantly differentiate by voice whithin the staff-level Pitch_squash_engraver? Can I read some grob property that tells me to what voice an object belongs?
