I spent some time futzing with Xpand2 trying to create a decent harpsichord patch, and I think I got pretty close. I zipped up two versions and put them up for download.

The second is one is a bit brighter and "bigger" than the first. They're probably not totally accurate, so maybe some others can improve upon it. Russ, if you like it, feel free to use it for your Xpand2 compilation.
