I see you've put an if condition to exclude input that is not event-chord.

There is now a problem: the below staff  is not printed when there is 
not an event-chord, and when an event-chord returns, a new staff is 
printed (with treble clef).

Pippo = <c e g c' e'>1
PippoDue = \chordmode {c1:/g}
PippoTre = c1
PippoQuattro = {<c e g>}

\new PianoStaff
\with { \consists #Span_stem_engraver }
<<
  \new Staff = "up"
  {
    \key c\major
    \autoSplitChord #UP <f a a' f'>2
    \autoSplitChord <g c' e'>4
    \autoSplitChord #DOWN <g c' e'>
    \autoSplitChord <c g e' c''>1
    \autoSplitChord \chordmode {c:/g}
    \autoSplitChord {<c g e' c''>}
    \autoSplitChord {<c e g> <d     f a>}
    \autoSplitChord c
    \autoSplitChord <c'>
    \autoSplitChord <<c\\e'\\g''\\g,>>
    \autoSplitChord <<c1\\e'2\\g''\\g,>>
    \autoSplitChord <<c1 \\ {e2 f}\\d'1>>
    \autoSplitChord <<
      {c4 d e f}
      \\
      {c' d' e' f'}
    >>
    \autoSplitChord \Pippo
    \autoSplitChord \PippoDue
    \autoSplitChord \PippoTre
    \autoSplitChord \PippoQuattro
  }
  \new Staff = "down"
  {
    \key c\major
    \clef bass
    s1 %bass staff appear only at the beginning, then reappears as 
another staff with treble clef
  }
>>

To avoid the problem, one can declare the lenght of the bass staff:

[...]
  \new Staff = "down"
  {
    \key c\major
    \clef bass
    \repeat unfold 16 s1 %bass staff is shown correctly
  }
>>

As shown in the attached files.

Perhaps there is a method to let the second staff to be printed without 
having to declare it's lenght.

Maybe there's a recursive (or something similar) method so 
\autoSplitChord can work with chord sequences.
\autochange accepts sequential input.

Me too. Scheme is not so intuitive for me, but sometimes I find a solution.

Thank you

Davide
