Logic has a long history going back to the mid 80s Atari 520 and 1040 home computers, when the program was called Notator. It has (with the appropriate add-ons) the ability to control a range of external devices, including hard disk recorders, like eg Yamaha's CBX series. It's not something exclusive to Roland and the VS AFAIK. And it was Apple who bought up Emagic, much to the dismay of PC Logic users.
