I believe any Sound Forge version handles it, even the lite ones.
It's menu-driven, I forget the exact sequence, though. All you're doing is adding a couple of pieces of info: a 3-digit tempo, and a two-character key. When I have to bounce into SF from Acid cos it's misreading a loop, it's really just a few seconds and I'm out again. But I don't do it often enought to have the process memorized, sorry...
There are a couple of extra things you can do - define it as a one-shot wav, or define a long sample as a beatmapped wav.
