If you have a keyboard controller - like it sound like you have, then it can't play sound at all. It require a sound unit.
What keyboard do you have? Does it have a in buildt sound unit so it actually handle audio, and can it import samples? If so, then it's not a controller, and then you can use sampled material in some way or another.
Do you like the way you can use a Analog Lab sample in your Logic sampler? Have you tried? Are you sure you can do, what you wan't to do when using samples?
