You only ever get one voice. The result of \autochange is a complete

hierarchy with the code and context changes somewhere inside. Putting a
\new Voice around all that will not achieve anything useful. You wrote:

Here is how to keep the basic framework but have it resulting in
separate voices:
\version "2.18.2"
scaleRH = \relative c' {c d e f g a b c c b a g f e d c
g a b c d e fis g g fis e d c b a g}
scaleLH = \relative c {c d e f g a b c c b a g f e d c
g a b c d e fis g g fis e d c b a g}
\score {
\new PianoStaff
<< \context Staff = "up"
<<
\autochange
\new Voice {
\voiceOne
\scaleRH
}
\autochange
\new Voice {
\voiceTwo
\scaleLH
}
>>
\context Staff = "down" {
\clef bass
}
>>
}
Note that I'm not using \new Staff ... here in order not to create a
staff competing with the one delivered by \autochange, but rather
\context Staff in order to mesh with what might already be created.
