Question: Trysound.com Routing

I’m sure many people have used try sound to test out a handful of sample libraries and instruments, but is there any way to route a midi on ones computer into the vnc client and application provided by trysound? A piano sample library is in my sights, but I’d like to try it with one of my songs-in-progress first.

Perhaps this is impossible, but it would be good to test.

Thank you everyone!

(I have a Korg SP-100 Keyboard connected to the computer in my signature, a macbook pro.)
