Change the tempo from 140 beats per minute to 60 beats per minute. This makes it easier to see the timing relations
For the usual time signature of 4/4, 1 beat is now 1 second in duration, and 1-bar is 4-seconds in duration.
Remove the Kicker instrument from Beat + Bassline editor, and add drum sample from My Samples.
Use this pattern for the Beat + Bassline editor and Song Editor. (If the image is too small, you can click to get the original size)
In the Song Editor we can see that bars 2 and 3 and not selected. That corresponds to 8-seconds, from 4 to 12, of silence.
Within the Beat + Bassline editor we can see that samples exist at 0-second, 1-second and 3-second. It should be noted that four position separation in this editor correspond to 1 second time-difference, for a 60 beats per minute tempo.
