EXS 24 Logic Sampler Users Group

Hey folks, first post, as you can tell by moniker. Found the glorious cone site 
for exs patches that connect to akai download files. (Hoorah...SOUNDS!) After 
a few sample downloads (Yes, long ones) I fell in love. Got pretty much the 
whole library, but... many, many mis-tunings. Some clearly two octaves up I've 
heard about this, even downloaded someone elses exs patches recently (I'm 
sorry I can't remember who, but I know you give great advice!) but still, wonky 
tunings. I've started tweaking in the editor and am wondering if I'm doing this 
right...
Set the key note to the audio file note info?
What about zone range? 
Should it  start at key note and go upwards 'til it hits the next file?
Is all this necessary or am I missing something? There are an aweful lot of 
files to manually retune. 
Thanks for all the great posts. I've been keeping my head low and listening for 
about a month, and hope to one day dispense advice like a sasha or one of 
the hienrichs.
