Thanks, but I have the impression that these affect the created object,
basically to do what \override does. But I want to ensure that a grob
*without* any explicit override to still have that default value.
Of course I could test if the propery is set to a meaningful value, but
that sounds somewhat unclear to me.

Doesn't set-object-property! do what you need? "In obj's property list,
set the property named key to value."

Hi all,
I've created a new grob property through
#(set-object-property! 'curve-layer 'backend-type? integer?)
I can now override this in the music, but it starts with an empty list
(it seems, at least that's what is printed). How can I initialize that
to, say, 1? I grepped for set-object-property! but didn't find any use
from which I could deduce how to do that.
I want to do that in the initialization code, without requiring the user
to explicitly put an override somewhere in the music or a \layout.
Any suggestions? TIA
Urs
