Ok, all you computer geekly pianists out there: isn't there some opensource program that does what Finale or Sibelius does? Have you used it, and which is the best?When I searched I found Lilypond and MusicXML, but both seem incredibly difficult to learn and hard to input (no GUI--except there's this Denemo GUI for Lilypond but it seems impossible to use...).So, I don't want to spend the $250 for Finalbelius. What are my options: just download an illegal version, or is there an opensource version that is decent?
