Change default MIDI name for Blofeld

* Previously the Blofeld registered itself via USB MIDI as "Waldorf Blofeld".
  Since Blofeld f/w 1.22 (or possibly earlier) it says "Blofeld MIDI 1";
  for some reason though, it is not possible to use this name to connect.
  However, "Blofeld" works fine, so we use this as the new default.
