Drum Shuffle

[Roberto Leibman]

I don't know if this made it before (I don't see it in the archive)

I have the following piece in 12/8:

hh8 r8 hh8  hh8 r8 hh8  hh8 r8 hh8  hh8 r8 hh8

In drum notation this is traditionally grouped with bars as this:

_____    _____    _____    _____ 
|     |  |     |  |     |  |     |
x  r  x  x  r  x  x  r  x  x  r  x

That is to say, groups of three, with an 8th rest in the middle.

I can't seem to get the beams to look like this. I tried the following 
settings:

%%% revert default values in scm/auto-beam.scm regarding 12/8 time
#(revert-auto-beam-setting '(end * * 12 8) 3 8)
#(revert-auto-beam-setting '(end * * 12 8) 3 4)
#(revert-auto-beam-setting '(end * * 12 8) 9 8)
#(revert-auto-beam-setting '(end * * 12 8) 2 1)
#(revert-auto-beam-setting '(end * * 12 8) 1 8)

%%% your new values
#(override-auto-beam-setting '(end * * 12 8) 3 8)
#(override-auto-beam-setting '(end * * 12 8) 6 8)
#(override-auto-beam-setting '(end * * 12 8) 9 8)
#(override-auto-beam-setting '(end * * 12 8) 12 8)

This works if I have three consecutive 8th notes, but not if I have the 
rest in the middle.

Of course, this can also be notated as 4/4 with triplets and a rest in 
between the triplets, but I see the same thing: no beams.

How do I notate this?

Thanks,

Roberto
