Alesis Andromeda A6

Hi everybody,

when finally I had some time to program a little with my A6 I 
noticed that the knobs do not quite react the way I expected. I  am 
trying to make a sound that I used to make on my MS10 (that I sold) 
and the resonance was at 8 on the MS10. But the resonance know 
(filter2) on the A6 responds not lineair to know movements. The 
first bit of the know hardly responds at all (also clearly visible 
in the display values) and the last part of the knowb turn makes 
giant leaps in values. I don't like that, it makes tweaking less fun 
for me. Why is this and more important, can I do anything about this?
