But it doesn't seem easy to use :D

    [...]
    ees8[( d] c4) ~ |
    \shape #'((0.7 . -0.4) (0.5 . -0.4) (0.3 . -0.3) (0 . -0.2)) Slur
    c2( | \change Staff ="lower" \stemUp c2)  \change Staff="upper"|

I was expecting this \shape to affect the slur that starts on c2, on 
last line. But I get this error instead :-S

Will continue trying to find out what is going on. :)

Thank you
