Re: custom articulation position

[Caagr98]

What you're doing is just creating a text script, not an articulation. I use 
the following code to create a custom real articulation; you'll obviously have 
to adapt some of it to fit yours.

```
#(define (draw-unaccent grob)
   (let ((stil (make-path-stencil '(M -0.435 0.435 C -0.435 0.185 -0.250 0 0 0 
C 0.250 0 0.435 0.185 0.435 0.435) 0.13 1 1 #f))
         (dir (ly:grob-property grob 'direction CENTER)))
     (if (= dir DOWN)
       (ly:stencil-scale stil 1 -1)
       stil)))

#(define unaccent-script-alist
   (cons `("unaccent" .
             ((avoid-slur . around)
              (padding . 0.30)
              (side-relative-direction . ,DOWN)
              ))
     default-script-alist))

\layout {
  \context {
    \Score
    scriptDefinitions = #unaccent-script-alist
  }
}

unaccent =
  -\tweak stencil #draw-unaccent
  #(make-articulation "unaccent" 'midi-extra-velocity -30)
```
