Sure.
Create a patch using only one zone throughout your keyrange with a rather
low key note (like C1 or C0). Copy that zone multiple times (otherwise on a
powerful computer you won't be able to notify the difference in CPU load,
there's got to be many voices playing).
Now play let's say a 4-part voicing close to the key note. Then play the
same voicing let's say 5 or 6 octaves above. Watch your CPU meter while
doing so, it will defenitely go up as soon as you play voicings being far
away from the key note. This is because the EXS apparently needs quite some
CPU power to pitch samples.
Also a good reason to use more than one sample all through your keyrange (in
case it's possible).
