Re: Slur from non-existent note

[Bill Mooney]

Hi Garrett ,
You could try this :-

c4^( s) \once \override Slur #'control-points = #'( ( -10 . -2) ( -7 .
0) ( -2 . 0) ( 1 . -2) )
 s^( d)

the ^s force the slur up'ards ( use _ if you want it down)
the numbers in the 'control pints part are found by trial and error :)
they're x,y pairs for places through which the curve of the slur must pass.
beginning from the note 'position' (in this case the 'd', rather than
the second 's') the first pair are where you think the 's' is, followed
by a point a bit closer to the 'd' but a bit higher, then another closer
to the 'd', then the end closest to the 'd' which again is a bit lower
.... I'd draw a picture but I hope you follow all this! :)

There might be a 'better' way but this seems to work.

Hope this helps
regards
Bill
