Heres whats happening: https://youtu.be/d7WywQXxkw8(About 20s on the video I move the hi-hat pedal up and down to show that it is working, but do not reach fully open anymore, after that I hit one pad to show how the VU behaves).
I noticed that:1) After connecting the other pads the VU meter no longer appears fully open (as can be seen on video).
2) Hitting any pad causes the VU to oscillate, and if I start Addictive Drums I can actually hear the hihat making some chicks noise
My config:1 dual trigger Roland-like for snare (internal - side mounted) - highlvl about 604..
4 single zones for toms and kick (internal - side mounted) - highlvl about 540..
