sure.
you insert the instruments/sounds VERTICALLY, and mark them everytime when they should make a sound (a clap or something...)
if u don't mark them, theyre silent (this is how to make a pause etc).if u finished editing the first pattern, say, when there is no more space, go to this digital interface (at the top/left of the pattern) and click it in order to switch to the next/previous one, and continue adding instruments, sounds etc...question answered?
