I try to find Chopin's concert No.1 and write it with Sibelius. I need the part of the orchestra. But it is impossible, the scores are all different and some are same in the half page and different to the other half and thus a completely outpouring effect. I lost a month and I am on the fourth page without being able to move on. It is completely paramount (sorry for my english ... faltso?). It is very important to find a solution because we have piano exams in this concert. Do you have any idea? I am in panic!
