Ah, great - thanks David!

This will certainly work for my (probably comparatively simple) scores - 
I'll use that.

But in general, shouldn't bar checks still be valid even if the bar 
number count isn't necessarily? Then again, maybe that's a rather 
academic problem - one would hardly code a score using bar (number) 
checks and then place "ignoreBarChecks" in *all* score blocks ... at 
least one of the \layout block will use the checks.
So, for me, this would work - but others with bigger and more 
complicated scores might have a different opinion on this.

I guess, a mention of this in the sections "Repeats in MIDI" would be a 
good idea - I'd be happy to do that, if the Doc-people let me know, how 
I can do that.

Thanks again,
Best, Robert
