Many of the Tyros' styles have tempo changes in the intros or endings (eg: World>Casatschok). How can I do this?

I didn't see a way possible onboard the Tyros, is it possible through an outboard computer sequencer? And if so how? I know there's a section in the Tyros handbook which deals with making styles on a computer, but it was not well explained. (I use Cubase).

Thanks,
Chony
