No, wait, unless I'm misunderstanding, I don't believe it can work this way. The whole issue is that Tascam has not provided a 64 bit driver for OsX, the last driver they (actually it was Frontier) wrote was a 32 bit driver for Snow Leopard. The machine that you physically hook the Tascam up to MUST have a working hardware driver for the device. It can't directly connect through a virtual driver, because there has to be a connection to the low level hardware layer FIRST. I mean how can it even see the Tascam if the Firewire isn't talking to it? THEN you can bridge or virtualize it or redirect it however you want. So unless your MacBook Pro is running an older 32 bit version of OsX, like Snow Leopard, I don't think it can work.
In my case I can use Windows 7 (64 bit, Tascam DOES provide a 64 bit Windows driver), or my old PPC running 10.5. Or I could use my old XP machine I used to run Cubase on. If you have a funky old mac, or an old PC running 32 or 64 bit XP or Vista, or any version of Windows 7, it can be your bridge. Scrounge around for an old machine. The nice thing about an old mac is that the network MIDI stuff is more integrated than the (third party) rtp.MIDI on Windows, Bonjour is built-in, etc. On Windows you need to download and install rtp.MIDI and (preferably) install Apple's Bonjour (it comes with Apple's printer support), without which you have to manually enter the IP addresses.
The hardest thing about these setups is when you change anything, because the whole Bonjour approach makes it reconfigure itself to make it easier, and instead it gets everything confused. Because I use both Cubendo and Logic, I use my iPhone and my iPad and my Kindle Fire and my Android Note 3 mapped as control surfaces into both my PC and into my Hackintosh, I don't always have all of them on hand, my wife steals them, so I have to switch, and it's always getting VERY confused. I go to use the iPad on Logic and find it's talking to the dog instead, I move the faders and the dog's ears start flopping up and down ... almost that bad.
The best way would be to use an old machine and hard wire it to your Logic mac with ethernet, not WiFi, plug the Tascam into it, configure it with just one Network MIDI port, define the Live Link, and let it be. Maybe even dedicate an old machine to bridging your Tascam. If you use a wireless device too, add it after the Tascam is rock-solid, and don't change anything after that. Don't let your wife stael your devices. Good luck.
