Your "best of all worlds" strategy can be done, although it will have hiccups and little hassles along the way, but that's half the fun, right?
I must admit thaf Galaxy and the super special MIDi editing in SVP have tempted me away from Logic 6.43.
True that SVP and Galaxy+Editors are hard to beat, but Logic and Soundiver are pretty formidable too. I do resort to Soundiver for units that Galaxy doesn't handle, of which there are unfortunately more than a few.
Initial thought is to send smpte from SVP over the Studio 5 to the Unitor 2 input on ny 4 meg ste and achieve a wicked blend of Notator and SVP to conquer all.
That would be really cool if it worked, but it's my sad duty to tell you that it won't. SVP will only send MTC, NOT SMPTE in real-time - and that MTC is sent over MIDI. The SMPTE functions on both the Studio 5 and the Unitor are there for striping tape only. If you can get Notator to chase incoming MTC over MIDI it might work,
though that may require an entire interface or two by itself. Anytime you have MTC running over MIDI, it MUST have priority over any and all other data, including notes and especially controllers or things will lose sync. Your interfaces will do this automatically, often causing glitches in the note-ons, pitch bends and everything else in the line. Having four serial ports on your Keyspan may come in very handy as it will enable you to isolate the MTC from all other MIDI.
Synchronizing two old-school DAWs on two computers is possible but always a challenge to say the least. Exactly how you might end up achieving it with Notator and SVP I can't say. I
can tell you this: It's easier to get the DAWs to just follow incoming code that to both play and "send sync code out to a friend" at the same time.
Although you'll try whatever ideas present themselves, I'll give you a "last resort" which will work. Both SVP/Studio 5 and Notator/Unitor are excellent at receiving incoming SMPTE and converting it to MTC internally (not 100% positive about Notator, but pretty sure). They can then play or record while chasing the code. You can add an external source of SMPTE to then feed to both DAWs, rather than try to get one to be a "master" and control the other as a "slave". That source can be a stand-alone SMPTE generator / synchronizer (which used to be really common, less so now) or a third computer running software that will allow you to use say, one of the Emagic interfaces to send SMPTE from a programmable starting point. Again, this is a "last resort". With a little luck, you'll find a better/easier way.
Allegedly could do all this with a laptop but it really doesn't do it for me at all.
What that
would do for you is drive you completely crazy in a very short time. Trying even to
see two DAWs and/or editors on one laptop, let alone actually operate them can only happen in a world inhabited only by marketing idiots.
