Hi Ronnie,
Unfortunately, I can't recommend a Style for the "Knight Rider" theme. But if you search Google for knight rider midi free you will find various free MIDI files of this title. Some of these sound pretty good. Once you've found a usable file, you can edit it as you wish (e.g. swap out voices, mute certain tracks, etc.) and then play "over" that file live.
Best regards,
Chris
