Hello, I need to put a few short Lilypond musical examples in my LyX thesis, possibly without using pdf or similar passages. Is it possible to have it put in some ERT box where I need them?
You could try to include the Lilypond passages as external document, see section 6.1 of the Embedded Objects manual.
If this doesn't help, I would cut out a PDF image of your Lilypond output and include it to your LyX document as image.
