Actually I'm not sure if it's related to my hardware or my settings

For couple of months I had no problem with my hi-hat. Finding the right settings was fairly easy and I was happy with the whole thing. But 3 days ago I changed my hihat stand and pedal (the old pedal was tooo cheap!), so of course I unplugged everything, put the optical controller back on my new stand and the old mark I had put on the rod no longer exists.
So I put everything back as normal (and enjoy my new pedal), but now there's something strange happening with the hihat (or controller?, or Megadrum?, or input, or settings?)
I can no longer find the right high and low values! I press the pedal and try to play with the Low value, but there's no way I can reach something close to 0.
And when the pedal is released I can only reach 127 if I set the value to 1023. But then the low value follows that setting and I get even further from 0.
It looks to me like no matter what values I chose, I always have a very small range (about 20) between low and high.
The worst part is that, when pressing/releasing the pedal I get random results
For exemple : with low value set to 192, I could only get as low as 50, and all of a sudden I get a 8
In other words, I feel like I have no REAL control over my settings!
