Bruiser,
In the Sample Edit screen press SAMPLE MODIFY and then NORMALIZE. If you want to replace the original sample, make sure there is a checkmark in the OVER WRITE box and then press EXEC. After you confirm, it'll take a few seconds (depending on how long the sample is) to perform the operation.
FBJ, "Normalizing" is not quite the same as EQ, the latter being something that boosts or cuts away from certain frequencies or frequency bands in the sample. When you Normalize a sample, you are boosting the amplitude (signal level) of the entire sample (not just certain frequency bands). Basically, what it does is take a look at the peaks in the sample, figures out how far away those peaks are from maximum level (not sure if this is 0 db for the FS, or if they build in headroom such as -3 or even -6 db), and then raises the entire signal level so that the peaks are at maximum level. This boosts the quiet parts of the sample as well.
Normalizing is quick and automatic, but, if you do it repeatedly, you'll introduce quantization noise into the sample (thus, it's better to just do it once). Your EQ method may work as well, but it will alter the harmonic content of the sample as well as the perceived volume.
The reason Normalizing works better on some samples then on others is probably due to the dynamic variation of the sample (if there is a wide range in your sample, it may not boost the low-level parts enough to help).
