Exactly, that was my idea. My problem is that I can't do it like in the 
percent repeat case, where we have percent-repeat-events (generated in the 
iterator), which start at the right moment and have the correct length. In the 
measure counter case everything is handled via context properties (or maybe a 
start/stop event), so there is no music event at the start of each measure and 
thus there is also no event from which I can obtain the length of one such 
measure-spanner.

So, to formulate the question a little more precisely: In the engraver, for 
which events or grobs do I have to listen/acknowledge to get the left and the 
right column for each bar?

I can't listen to bar lines, since there might be mid-measure barlines, or no 
barline at all (think longa or breve)...

Cheers,
Reinhold
