Hello Hans, LilyPonders,
Thank you! I added the line to my Staff context, and everything worked as expected.
\override BarLine.space-alist.next-note = #'(fixed-space . 1.2)
I wanted to refine the solution and add space only *after* double-bar lines, but adding the following to my bars doesn't seem to have any effect
\once \override BarLine.space-alist.next-note = #'(fixed-space . 1.2)
My bars section (separate from note input)
\skip 1*16/4 \once \override BarLine.space-alist.next-note = #'(fixed-space . 1.2) \bar "||"
\skip 1*16/4 \once \override BarLine.space-alist.next-note = #'(fixed-space . 1.2) \bar "||"
\skip 1*16/4 \once \override BarLine.space-alist.next-note = #'(fixed-space . 1.2) \bar "||"
\skip 1*8/4 \once \override BarLine.space-alist.next-note = #'(fixed-space . 1.2) \bar "||"
Many thanks,
