Hi, I am laying down a drum track with se4, the kit is called Problematic (very apt lol) which has instruments and patterns, I would like to change the closed sticks instrument to claps and also change the snare to a different snare which would reflect in the patterns when played, I have tried and tried but I cant seem to find a way to change the instrument in the kit, I am sure I saw this done a while ago on YT but I cant find the vid, can anyone advise me please?
thank you so much 
N.B. OK I found it, drag sample from the media bay onto the pad
