Grace note displayed exactly on beat (and not before)

[Siska Ádám]

Hello List,


I know about the \grace, \appoggiatura, \acciaccatura and \afterGrace commands 
which can be used in order to create grace notes. However, none of these would 
put a grace note exactly on the beat: they would either put it just after the 
`main' note (in the case of \afterGrace) or just before it (in all other 
cases). I was wondering how I would be able to put the grace note just on the 
beat.

To illustrate the idea, I attach an example (scanned from a piano score). This 
is not the actual scenario that I wish to typeset, but it illustrates my need 
quite clearly (I need to typeset a short passage in an orchestral score for one 
of the instruments, where the passage itself should start at the same time as 
the other instruments start to play).


Thank you for any help,
Ádám
