Re: automatic beam direction for multiple voices

[Vaclav Smilauer]

Thanks, Graham, that works...!

Moreover, I found that the voices must be 1-2 or 3-4, mixing \voiceTwo 
with \voiceThree will not work. The trick is to call \voiceTwo or 
\voiceThree on the middle voice when switching to upper or lover staff 
respectively.
