Hi list,

I have a chord with \laissezVibrer attached and I want only one of ties:

%% snip - snip - snip
\version "2.19.65"
{ <c' g'>\laissezVibrer }
%% snip - snip - snip

I want e.g. only the tie from c' (and/or only from g') but not both.

I'm kind of sure this should be possible in lilypond (as more or less
everything is possible ;) but I'm lacking the magic incantation.

I'd be happy if someone could help me out.

Thank you,
Michael

Hi Michael,

I use this snippet when I need a single lv in a chord...this what you're looking for? Just a starting point...
