harpsichord

So now that I know that a harpsichord synth is used on "In The Light" (thanks to isteveus for that), does anybody know how I can adjust the various settings to get a sound like a harpsichord? I know that you can get a harpsichord with one of the jampacks, but I really don't want to spend $100 for something like this. I unfortunately don't know much myself about creating different sounds with garageband, beyond the fact that I know you can change the tonal qualities by clicking on the details button, so any help would be appreciated. Thanks.
