Text button in Homepage

Hello, I go to the Theme options and then to Excerpt options. In the field "Read more text" i can write my personal text. In the demo version the two slider images of the home page, have two different text, Eplore Music and Rock Star. How can i do it the same? Here in my setting, i see a one way option, a single text for all the sliders page. Thank you for your help. Joe
