help with vocal-sample , please

[milesahead]

hello all,
it would be very nice, if you could help me out with this:
i found a rock-sample , kind of refrain-hookline,
acapella - wich is two bars long and ending with a short repetition.
i would like to use it in a straight techno tune.
i`ve already cuttet the thing.
if i load the cutted sample in live, it recognizes a two bar loop,
wich it isn`t,

now, i don`t know how to tell live that this sample should have
40 steps in length.
16 steps for the first turn, 16 for the second ,
and 8 for the turnaround.
how can this be done?
