EXS 24 Logic Sampler Users Group

Being quite new to the EXS24, I may miss the obvious.

Here is the problem: sounds imported from the Wizoo Platinum Drums CD have 
more than 8 velocity ranges (zones) per key for some of the instruments (e.g. 
hi-hats and snares). But EXS24 will not play those zones that are assigned to 
ranges beyond eight. Lets make an example:

for one key, there is two zones (left/right) for each of the vel-ranges:

01-10
11-20
21-30
31-40
41-50
51-60
61-70
71-80
------
81-90
91-100
101-110
111-120
120-127

this makes 13 velocity layers for one sound. All the zones triggered from 
velocities higher than 80 are not played. 

It seems not to be a problem of the number of zones, since the "upper" zones 
for higher velocities are played, if velocity is set to be within 1-80.

Is this a bug, or a known limitation?
Any help is appreciated.

kind regards,
