Re: Help for \beamExceptions

[Simon Albrecht]

Hello Richard,

if you want to use \beamExceptions, it seems like the only way to do this is
%%%%%%%%%%
\version "2.19.25"

{
  \time 4/4
  \set Timing.beamExceptions = \beamExceptions { 8[] 8[ 8] 8[]  8[] 8[ 
8 8] }
  e'8 f' g' a' b' a' g' f'
}
%%%%%%%%%%

– that’s a bit cumbersome and IMO it should lead to the same result with 
{ 8 8[ 8] 8  8 8[ 8 8] }.
So currently this is a case where the immediate, Scheme way is more 
straightforward:

%%%%%%%%%%%%
\version "2.19.25"

{
  \time 4/4
  \set Timing.beamExceptions = #'((end . ((1/8 . (1 2 1 1 3))
                                          (1/12 . (1 6 2 1 2)))))
  e'8 f' g' a' b' a' g' f'
  \tuplet 3/2 4 { e' f' g' f' g' a' g' a' b' a' g' f' }
}
%%%%%%%%%%%%

Yours, Simon
