Some examples:

rockon2: 0 4/4 120 xXxX
solea: 0 12/4 180 xxXxxXxXxXxX
shuffle: 0 12/12 120 x.xX.xx.xX..
funky: 0 16/16 120 x.x.X..X.Xx.X..X
The 12/12 for the shuffle create 1/4 triplets. Just do a bit of math;-) This is still a
metronome, not a drum machine, but it can act like a basic one, helping you to figure
out a certain rhythm within the meter.
The UI is developed so that it fits into the display of a Sansa Clip+ and that is the
hardware device it is tested on. It seems to work reasonably on some other models in
the simulator.
At last, a more complete tempomap file:
