Actually, I've found an unintended consequence of this method, in that it changes the bar for all staves, not just the one in question. See the circle in the graphic below - all bar lines at this point were changed, not just the top line

Yep. The \bar "whatever" - command is applied to the whole score. To get a different bar-line in only one Staff of Score you have to set the whichBar-property accordingly.

Like the code below (using a second Voice for controlling, as Simon suggested already):

m = {
  \time 3/2 \repeat unfold 3 { c''1 }
}

ctrl = {
  \repeat unfold 2 { s1. \bar "b" }
}

ctrl¹ = {
  s1. \once \set Staff.whichBar = "S" s \once \set Staff.whichBar = "|"
}

<<
\new Staff << \m \ctrl >>
\new Staff << \m \ctrl¹ >>
\new Staff \m
\new Staff \m
>>

 

(and what's going on with the bottom line, I don't know). 

No idea what's causing it.

Could you provide a tiny example?

This is the solution that worked for me. One problem I had was that if the note goes over a bar line (as in the first example), the bar line is drawn before you specify the bar type, and you get two bar lines (see second example). 

In the third example, I set the defaultBarType before specifying the note, which causes the right bar line to be drawn. Then I set it back again. It's a bit fiddly, but the result is exactly what I'm looking for. 

--

% setup as before in the previous email

{

  % without any changes to bar lines

  \time 3/2

  a'1 b' c''

}

{

  % draw bar line with specific type (get two bar lines, as the b' causes a bar line to be drawn as well

  \time 3/2

  a'1 b' \bar "b" c''

}

% shortcuts

fullBar = { \set Timing.defaultBarType = "|" }

splitBar = { \set Timing.defaultBarType = "b" }

{

  % set default bar line before drawing b', then set it back again 

  \time 3/2

  a'1 \splitBar b' \fullBar c''

}  

The result looks like this:

Where the last one is what I was aiming for. 

Thanks everyone for your help!

Btw, I'd prefer you'd attach images. Per default, I always filter in-line images, maybe others as well.

Or give a hint that inline-images are present, then I'll look up your mail in the archives.

Thanks.

Hi Murray-Luke,

alternatively you could define your own bar-lines, leading to:

\version "2.19.18"

#(define (make-up-tick-bar-line grob extent)
  (let* ((line-thickness (layout-line-thickness grob))
         (thickness (* (ly:grob-property grob 'hair-thickness 1)
                       line-thickness))
         (staff-space (ly:staff-symbol-staff-space grob))
         (height (interval-end extent)))

    (ly:round-filled-box (cons 0 thickness)
                         (cons height (+ height staff-space))
                         0)))

#(define (make-down-tick-bar-line grob extent)
  (let* ((line-thickness (layout-line-thickness grob))
         (thickness (* (ly:grob-property grob 'hair-thickness 1)
                       line-thickness))
         (staff-space (ly:staff-symbol-staff-space grob))
         (bottom (interval-start extent)))

    (ly:round-filled-box (cons 0 thickness)
                         (ordered-cons bottom (- bottom staff-space))
                         0)))

#(define (make-both-tick-bar-line grob extent)
  (ly:stencil-add
    (make-up-tick-bar-line grob extent)
    (make-down-tick-bar-line grob extent)))



#(add-bar-glyph-print-procedure "u" make-up-tick-bar-line)
#(define-bar-line "u" "u" #f #f)

#(add-bar-glyph-print-procedure "d" make-down-tick-bar-line)
#(define-bar-line "d" "d" #f #f)


#(add-bar-glyph-print-procedure "b" make-both-tick-bar-line)
#(define-bar-line "b" "b" #f #f)
