What looks like quarter notes, is simply beamed eighth notes. But the second 
eighth is hidden, which hides the beam as well.

What might be confusing is that the auto beamer inserts beams in a way you 
wouldn't expect. This is for the same reason as you get warnings: you need a 
separate voice for the rests, since you can't have a rest and a note head 
together on a stem. 

If you remove all hideNotes commands, it will be easier to follow what's 
happening.
