Re: Can't use edition engraver to place \time and \tempo

[caagr98]

I didn't notice any timing problems with \time. Of course, if you use it 
to add a time signature somewhere weird it gets broken, but that happens 
with inserting random time signatures in the source as well. If used 
responsibly, it works fine.

My \tempo patch seems to work (needs some more testing first). Shouldn't 
be too hard to make one for \time, I hope.

Oh, and another thing - it seems EE creates its own grobs for 
TextScripts and Marks in process-music, rather than handing them to the 
proper engraver in start-translation-timestep. This makes tweaks and 
other custom properties not work, let alone if you install a custom 
engraver for them. Moving their handling to start-translation-timestep 
seems to work fine, so why is it that way? (It does have the advantage 
of allowing multiple \marks at once, though.) TextScripts also don't 
work in the first measure if it's a MMR, which is weird. (Placing an 
empty chord before the MMR makes it work.)

I'm all for having a way to manually place texts/marks, but I personally 
think using the default method should be the, well, default. Changing it 
could break existing projects that rely on that behavior, though, which 
is bad.
