EXS 24 Logic Sampler Users Group

I called up the Wizoo CCloopz instrument within EXS24 and can't 
seem to get any of the zones to loop continuously.  I thought all 
you had to do was click on the loop button in the edit page and 
that was it but the loop always finishes after one play and doesn't 
repeat even though I'm still holding the corresponding keyboard 
key down.  Any ideas?
