Yeah like the beat is on a bar of four - dum dum dum dum. You got the same number of notes/samples per bar. Say every other bar (4 beats) you have one note the same next one higher next one lower then next bar back to the same. Like on the note track for the pulve for an example you could go A2 A1 C1 A3 A2 A2 A2 A2. I know I'm not very clear - not musically trained!
