Pro Tools 9 & 2 usb keyboards

[hawkesk57]

I have 2 usb keyboards, a Casio 88-key CDP-130 and a Novation Launchkey 61 running Pro Tools 9.06 on a Win 7x64. Both keyboards are connected to Pro Tools 9 via separate usb ports, not a usb expander. Setting up 2 instrument tracks, both are recognized as different instruments on the INSTRUMENT dropdown. I select the Launchkey for the DB-33 in the predefined dropdown, channel 1, and the Casio for the Minigrand predefined dropdown, channel 2. I can't separate them - both keyboards control only one sound, I want to use them in a live setting where the Casio plays the piano sound, the Launchkey plays the organ. What am I missing?
