I'm working on a piece without barlines or a time signature. The file is attached below. I have tried using the \cadenzaOn command, but this seems to produce nice output only when I use a simple time signature (4/4) and manually bar (|) the input. Unfortunately, the rhythmic values I'm using do not lend themselves to this approach. The introduction of a couple 16th notes shifts everything over and makes it impossible to divide things into neat 4/4 bars.
My current solution modifies the layout's context block to completely suppress barlines and time signatures. However, since lilypond still thinks I'm in 4/4, I'm getting ties across invisible barlines. Also, since all barlines are suppressed, I can't get a double bar line at the end. Is there any way around these problems? Is there a way to produce meterless music without the ghostly ties that still includes a double barline at the end?
