Recording Roland V-Drums into Garageband using MIDI?

I have a Roland TD-12 V-Drum setup, a MIDI interface, with Garageband 4 on a MacBook Pro.

I can record the drums using an audio out cable from the TD-12 brain directly into Garageband, that's fine. However, I'd like to do this using MIDI instead, and I'm realizing that maybe Garageband does not have this capability... but maybe I'm wrong, am I?

If I am wrong, should I be using Logic Express, or Logic Pro instead?

Any words of wisdom on this subject is much appreciated.
Thanks.
