I just got the Tascam DR 70 from B&H and it came with the Sound Forge Pro 11.
Does anyone knows if I am aloud to sell it.

Yes, you can sell SF11. However, if it was previously registered with SCS, the new owner will not be able to 'upgrade' to a newer version at a discounted upgrade price. If it hasn't been registered, it's just like new.. (either via download or on a disc) as long as one has the serial # . SCS does not use the annoying dongle system.
FWIW, There is no cost for updates for registered users (currently Build 293). SF11 includes CD Architect, iZotope mastering suite, Nectar Elements and the SCS Noise Reduction suite 2.0. SF will run on both 32/64 bit systems.

it hasn't been registered.
Thank you. I'll just go a head and put it for sale.

The OP has Sound Forge not Vegas Pro. Though I would guess it could be sold??

Sound Forge .. DUH!
Anyway, the same applies to all SCS products.
I've edited reply #2 to show Sound Forge instead of Vegas
