Hello again,

sorry for reposting, but thunderbird (again) crashed the code layout ...

Cheers, Jan-Peter

Hello list,

I am experimenting with scheme engravers and have an issue with simultanious voices.

This little snippet prints out the barnumber and measure-position for each engraver, when start-translation-timestep is called.
The output here is:
--snip--
1: 1 #<Mom 0>
1: 1 #<Mom 1/4>
1: 1 #<Mom 1/2>
-- here are voices 2 and 3 missing for #<Mom 1/2>?
1: 1 #<Mom 3/4>
2: 1 #<Mom 3/4>
3: 1 #<Mom 3/4>
1: 2 #<Mom 0>
2: 2 #<Mom 0>
3: 2 #<Mom 0>
--snip--
so, the start-translation-timestep slot is not called, when the new voices are newly created. I want to push overrides at specific locations using this engraver. This is done in the start-t..-slot.

Why is this not called?
Does anybody know?

Best wishes for the new year!
Regards,
Jan-Peter
