The Dr. Rex is a special kind of sampler that plays back loops and sequences. It is designed to adjust music or beat loops to song tempo using special samples called slice files.
Slice (.rx2) files are complete music and rhythm loops chopped up and reassembled, so that the slices can be spread farther apart for slower tempos or pushed closer together for faster temposwithout altering pitch.
