I have been following the vexflow tutorial for rendering which gives an example for rendering a single stave. This works fine. I now want to render both the treble and the bass which is not explained in the guide. The simplest way I can think of is to just duplicate the example code to render both.
This kind of works but if I take an example rendered using another tool you can see my example is missing the { joining both sides as well as the line between the bars. Does vexflow offer some built in functionality to render both staves?
