Nothing so easy as Scope.
It's just like hardware, cabling does the job.
You load the modules (synths, mixers, hardware inputs (midi spdif, ADAT, Midi) and software in/outputs (Asio, midi) in the project, cable them, and there you go.
Rightclick on the grafical presentation of the module to get the GUI of it, and edit your synth, mixer, etc.
Save it as your default and there you go (again).
Only the use already of the 4 or 8 topsynths (partly pure emulations) mixed and premastered in a project is totally worth the price, it's a bargain actually.
At first sight it looks like complicating your setup.
It is, to some degree, but if you're after
sound you shouldn't care, you win everything, including a subtle difference in sound and quality from the millions of regular VSTi users....
Regarding complexity, in fact you just add an ASIO and a Midi layer to your native sequencing setup.
What about using external gear? You won't say no to an original Minimoog, ARP etc.
Now you have it inside your computer, including a virtual top studio, all with total recall...
If you don't like to be an engineer yet wanne have quality, you
should check Scope

The only comparable alternative is proTools, tho Reason could be a great alternative to the right user.
Scope is damn stable also, to end with that one
