Yes, I'm aware of that, But it's not a solution to my intent. Snippet 312 
works well for a "fixed" part: a given combination of percussion voices, and 
a fixed page size. 

If one changes page width, then one might need show/hideMultiRests in other 
places. But it's still doable although it's labor intensive.

But in a SCORA context, we want to give the percussionist the option of mix 
& matching the different voices to his liking, depending on how many 
percussionists there are and how their gear is organised on stage. And this 
is where the manual workaorund of the snippet completely fails. 

Given that the somewhat opposite of what I want (the 
Keep_alive_together_engraver) is written inside LP in C++, I assume what I 
want will also require a custom engraver - it's likely not a simple Scheme 
function...

Unfortunately, it doesn't :-(
