Can't play midi files from Fl studio. What is wrong?????????

[Drfist.]

Hi Guys,i have just purchased a Krome with Fl studio with the intention of editing midi files in Fl and then saving them with "Krome" sounds afterwards. The problem is I cannot get Fl studio to play the Krome. I can see midi messages going to Fl studio and when I press play on Fl studio the sequencer will start on the Krome but no sounds will play.

How do I get the sounds to play on the Keyboard???????

Thanks!!!!!!!
