PulseDivider.ar(t,2) isolates every second trigger. PulseDivider.ar(t,4) 
isolates every fourth trigger. Having a look at a graph might help 
illustrate why the PulseDivider.ar(t,2) is triggering first:

{ PulseDivider.kr(Impulse.kr(10), [2, 4]) }.plot(1.0);

The solution is to offset the counter for the first bass by changing the 
"start" argument to PulseDivider. Try replacing PulseDivider.ar(t,4) 
with PulseDivider.ar(t,4,2).

Nathan
