Cubase can be pretty modular using the track preset method. Just set up your instruments once and save them individually or save them as blocks. Then just drag and drop them in from user presets media menu.
My only reservation on 9.5 using this method, was it was slightly buggy sometimes. Cant speak for v10 though, yet...
The problem with Track preset is that Media Bay totally sucks (slow and bloated)...finding them is a nightmare.
There's also a slight annoying delay when scrolling through presets as CB tries to play it even though audition is turned off...hopefully they got rid of this bug in v10.
Best track preset workflow is by far PT. Its database is lightning fast and simple yet very powerful. Studio One is pretty good also.
