John,
I am the dealer in Los Angeles. I stock the Genesys Pro keybaord, the WK2 module, WK1 keyboard, and the Generalmusic Promega Pianos. I can order the Genesys XP module but it's price is a bit steep for stocking in my store. If you come in and try the Genesys and like it, I will be happy to order a Genesys XP module. The keyboard does the exact same thing.
