Triggering recording with midi

[MadStrum!]

I have a keyboard which i want to capture the drum loops from, and there is only a midi connection from the keyboard to my soundcard...
how do I trigger the recording in Sonar to start only when the first beat from the keyboard is sent to my computer?

Thanks.

Pier.
