Maybe I've express wrong my needs, I've routed some sinths tracks, or guitar tracks to a bus like (Group), In this Group I would like to automate effects and volume. To make this automation, I've to open a new automation track, assign this track to the bus, add all the feuwture need in the page menu, than back to track and write the automation. In Cubase is very simple, maybe the only good thing in cubase :-), open a bus then a bus track, group track as you want is easy to program, write and automate. The big problem is copy these automation to another automation track for another Group....... I hope this help to be clear.
