Re: Autobeaming with subdivision in 4/4

[Hugo Flordal]

OK, thanks, that's one solution... but I guess that is not 
the "right" way of doing it? Another way to do it is to run 
these lines instead of the 4/4 specific ones I gave in the 
example file.

#(override-auto-beam-setting '(end * * * *) 1 4 'Voice)
#(override-auto-beam-setting '(end * * * *) 2 4 'Voice)
#(override-auto-beam-setting '(end * * * *) 3 4 'Voice)

Then (surprisingly(?)) it works fine, and the output looks 
great. However, I do not want */* rules since I want to 
place these lines in a generic definition file that I 
\include everywhere, which would mess up all non */4 scores. 
(Right now I have a beautiful definition file where 
everything but the auto-beaming is configured nicely for my 
scottish snare drumming needs.)
  So... can it be done "the right way" (presumably by 
reverting and overriding the auto-beaming rules(?))? Or 
perhaps these are bugs that I, as a user, can not overcome 
without hacks like these?

  thanks
