EXS 24 Logic Sampler Users Group

Hello everybody, I'm new to the list with a Q:   I've got some snaresamples in a 
folder (all in the same folder) named 1,2,3 etc. I want to load them 
cromatically, with Zone 1 carrying sample 1 and Zone 2, carry sample 2 etc. 
They all load fine ,but for some reason I can't figure out, they won't load in 
sequense?! Sample nr 3 could end up in Zone 1 and sample nr 20 in Zone 4 
etc. Does anybody know how samples should be named in order to load 
correctly? 

Thanks!
B
