LDP language is an external representation, as text, of LenMus scores. LenMus aim is not that the user has to enter scores by using the LDP language, but to offer a full featured graphical interface to enter and edit the scores. Therefore, users don't need to know anything about the LDP language. Nevertheless, for users, LDP can be of help to prepare scores as text files to be later processed and finished using the LenMus program. In fact, this is the only possibility at current program version (3.1).
