How to make a Multi Curve Brush??

Hey,
What is the difference between the CurveMultiTube brush and the CurveTube brush?
I know what they DO differently, but I can’t find a setting anywhere that is making them behave differently…
I’d like to be able to create a MultiMeshInsert brush that allows me to place multiple curves… but I can’t find out how to do this anywhere…

any help would be greatly appreciated.

cheers
