Emax

I have had success downloading Emax samples for my EmaxII using EMX, 
but like some have said in the previous posts I have read, the sound 
quality is poor and seems to 'cut out'. Someone mentioned that it 
could possibly be the sample rate conversion causing this. Is this 
something I could fix, and if so, could someone give me details on 
how to do it, or an alternative fix? Thanks !!
