Erroneous output: file MIDI

Using MS Windows Home Edition
Lilypond version: 2.8.4

The problem persists also with the 2.8.4 version. I realized this code, a 
little shorter than the first I sent:

\version "2.8.4"

I also realized the same code, but with only the notes (without slurs, ties, 
etc.):

\version "2.8.4"

                \set Staff.midiInstrument = "violin"

The problem, in this case, concerns only the violin I.
I don't understand how is that (there are grace notes also into the cello part).
