I have waves multi tap, dosen't yours have a button to click to set the tempo? You can also enter in a temp next to the tempo button. There's also the sliders that have numbers by them (+1, +4, etc) that's where the next delay will play. You also have to activate the delay by clicking the button to the left of that slider. If you don't want the delay as loud you can change the volume of that delay with the box next to the activate button for that track. Hope that made sense!
