EXS 24 Logic Sampler Users Group

Hey Folks,
I've been chromatically sampling the raw wavefroms from a bunch of vintage (80's
era) synths. I'm wondering if it is best to normalize each individual sample, or
should I allow the natural taper remain from the low to high notes? I'm sure there are 
arguements for and against, not withstanding the integtrity of the normailzing algorithms, 
but on a technical level, are non-normailzed samples going to be tapered twice - once by the 
synth and then by the EXS?

Thanks,

Matt
