How to play original sounds from Yamaha Ez-200 on Logic Pro

Hi , I know that I can use the piano as a midi , which is great , now , how do I make the sounds from the Yamaha keyboard play on Logic or any other program instead of having to use the sounds logic only allows me to use . Because I can record what I want to play on the piano but unfortunately , the sound will be replace by logics library sounds and not the original pianos , so how do I get the original sounds to stay and play ? Is there a driver I should be using ?
Btw , I am connecting it through steignberg ur22 . Please help , I really want to use sound " Synth Pad 081".
