[LAU] Mackie Control "Universal" vs. "Pro"

Hello, I have an opportunity to buy a used Mackie Control Universal. Info at these links. http://www.mackie.com/products/mcu/mcu_support.html http://www.zzounds.com/item--MACCONTROLUNI But, I'm wondering if the non-Pro version, Mackie Control Universal will work as well with Ardour as the Pro version. Does anyone know? Ardour's manual says that the Pro version works well. My main reason for wanting the unit is my presumption that it has the ability for me to "touch" edit automation. This is something which my BCF2000 can't do. I've been scouring the web for documentation to tell me if it has this ability. But, so far I haven't found anything, not even in the MCU manual. Anyone know that as well? Thanks folks.... -- Kevin
