Oops...this could happen even to the best.
Just for curiousity...did you still have such a small gap between the low and high level?
I got the chance to test the td30 with vh13 for a hour last week and my feeling after have been playing with the system was that my MegaDrum with my VH11 is equal/slightly better in performance and precision seen from a pedal angle - however, i have still some work todo on the hihat bow/edge triggering on my system to make it to be equal. I do also truly beleive that the sound coming out from my Addictive Drums/Metal AdPak is way beyond the sounds found in the TD30.
On the roland TD30 associated pads i believe that roland have done something to create the extremly wide dynamics found on the pads when playing softhits...and changing to hard hits.
I really wonder how they do this....
