Re: beams in DrumStaff should be parallel to staff lines

[Jacopo Binosi]

Hi Ziggy!
Did you try with

\override Beam #'positions = #'(4 . 4)  (you can cange the values to see 
what happends..)

You can find other samples in the snippet repository searching "Beaming" 
or "autoBeaming" :)

Hope this helps!
