Nothing like a little experimentation and a lot of luck. You can look at the other tracks (without a wheel) by putting you cursor in the far right strip, holding down the left mouse button and moving it up, look to the right and you will see the tracks change. BTY, you can resize the Track with the +/- magnifying glass in the bottom corner.
Unfortunately, it is this random "payoff" (I think the technical term is variable interval) schedule which keeps us working an comptuers knowing that if we just try/experiment/curse/worry etc enough, we'll get them to work!
