No indication for accidental notes.
A single note in the parsed data does not actually show the expected note according to key.
For instance, I am parsing a tune in a key(D) meaning theres a sharp on all F's and C's, but the notes shown are the row ones(f & c) and not (f# or c#) - all accidental notation signs(flat,sharp,natural) are missing.
This might be prescribed inside the note, or probably added as other attributes.
