my pleasure.
i'm involved with Scope because i'm an engineer/artist and i like a useful product.
even mixing in Scope, you can still use your UAD and Duende(and native) plugins in Cubase inserts or busses. compressors and gates should be inserted first anyway...then you can send indiviual outs, or stems into Scope. once inside Scope, you have another potentially GREAT set of tools, and access to the outside world in REALTIME. NO "in the box" reverb compares with say, a Bricasti, and it's nice to be able to use gear like that inside the mix, if you have it, with no latency issues. the same goes for using a bunch of guitar boxes. Scope allows you to go in and out of the computer as much as you like without having latency making things impossible. this is really nice when doing overdubs and puch ins, because when the sequencer AND the input are monitored in the Scope mixer, there's no lagtime.
SSL, Sony Oxford, and Euphonix consoles, also mix on Sharcs, the Scope mixer is very good. the stock plugins are pretty basic, but Scope cards and the basic plugins were used in the Fairlight Constellation, so there are some useful things in there. the 3rd party developers like DAS, Wolf, Space F, and Brainworx have all done compressors, delays and eqs which are as
easily good as anything on Duende or UAD, although it's always nice to have both, because even though Scope has all the tools covered between S/C and the 3rd party guys(and would be fine on it's own), they are not exactly the same and one can never have too many tools. Scope tools are REALTIME however and can even be(and are) used live. the Movie Gladiator was mixed in Scope.
since you're into synths, you'll want as many dsps as possible. John FREAKING Bowen who programmed on the original Prophet 5 and Kog Wavestation, makes synths for Scope. the soundtrack of Batman Begins is Scope(Zimmer again). Space F makes a different type of synth and cool modular modules, and Adern's Modular Modules are already becoming legendary in certain circles.
there have also been some nifty FREE offerings from the SDK developers. some of those with 14 or 15 dsp cards and the desire to design have obtained an Software Developement Kit that allows them to make devices...
Scope is very different and hard to explain, so please excuse me for the rant. this stuff is such a no brainer value, i became a salesman for them. S/C is a very small company and only us users can let others know how great it is. S/C can't afford to hype the product properly(and it'd be really hard to explain quickly even with lots of money(although buying lots of magazine ads always gets a lot of warm and loving reviews

), so that potential users might even know what it is and what's possible! so here i am...
basically, Scope is a virtual room of gear. the sequencer is just a multitrack tape deck whose i/os show up in Scope as do Scope's hardware i/o. the result is that everything inside the computer will connect in realtime to everything else inside the computer. also, everything inside the computer will communicate with everything OUTside the computer and vice versa, and in realtime. because of this, and because Scope is a roomfull of expensive gear, it never really becomes obsolete. even in an old, free computer used as a multi out synth module or a multi i/o effects module and/or mixer, it will ALWAYS be useable and worth every penny, something no other computer gear can really boast.
