EXS 24 Logic Sampler Users Group

I am triggering the BodyResonance wav for my "OLD LADY" (making my 
own EXS instrument).  If I turn on the "One shot" it plays the sample 
fine...but I don't want the WAV to continue if the sustain pedal is 
released.  So I want to use a LOOP instead of the 'one shot', but 
when I switch it to loop....no sound.

Any one have this sort of thing happen to them??
