[LAU] Errors in Rosegarden's export to Lilypond

  Rosegarden is definitely the best sequencer I ever used. But I have some problems with it as notation editor. I have read some tutorials in Rosegarden's official site but have not solved my problem. I want to keep the music I write in Rosegarden as pdf scores also so that it may be readable ad easier to play on real instruments. However most of the time exporting as Lilypond files or printing (wich seems to use the same process of Lilypond) brings a lot of errors. I did small notations experiments using scores with few measures nd it was ok. Everything was right. But if I type a larger work such as a sonata or a symphony, using articulation symbols, stem directions and so on I always get errors in the Lilypond file. Most of the errors on Lilypond output are related to tenuto or stem up / stem down properties, but I need these settings and they are correctly displayed on small scores (for example those that I wrote as test files with one staff and eight meaures) but not in larger works. I use currently the most recent version of Rosegarden, that is, 11.06. At every update they say to have improved Lilypond export but it still doesn't seem to work right. What do I do to have Rosegarden music printed correctly? Fernando Martin
