This is a sequence of the 3rd movement of Shostakovich's
12th Symphony ("The Year 1917"); the movement is subtitled
"Avrora" for the ship whose cannon shot was the signal to
begin the storming of the Winter Palace.

   The sequence is for the Proteus 2. Note that the Proteus 2
automatically transposed down an octave all programs for
the Basses, just as real basses sound an octave lower than written,
so I have transposed these tracks (pizzicato bass and arco bass)
down an octave already. If you're playing this on a Proteus 2,
simply move them back up an octave (simple, no?)
