New drums: Kick pedal question.


My xmas 'from me to me' present was a Roland TD-9K electronic drum set.  I have a concern with the drum kick.  I think I have it set up properly and it's either a setup problem or a user/technique issue.  The instruction manual says you can adjust (insert list of a bajillion variables) and 'set it up how you like' basically, without explaining how each variable effects the end result.

My problem
The kick pedal is set up as per the instructions and occasionally (every few beats) double-taps.  The hits are extremely close together, and are hardly audible if you're not listening for them, but they do exist in the midi data. (i.e. 1/64th beat later) The hammer is physically bouncing and hitting twice, it's not just spurious noise or an oversensitive pickup.  The brain lcd has a

What I can adjust:
Technique:  If I move my foot a bit it changes the harmonic frequency of the hammer, and it can solve the problem, but sometimes my foot ends up back where the problem exists
The pedal assembly:
-Spring return tension -- more tension = ability to hit faster but more effort required, problem exists everywhere from full soft to full firm.
-Hammer location - it's centered on the sensor per instructions, and strikes flat and square. I could move the pedal off to one side slightly, or change the effective length of the hammer so it hits higher or lower (would change the periodicity of the system).
-Angle of the sensor - per instructions is set straight vertical.
-Electronic filtering - I can tell the brain to ignore hits for a period after a given hit to eliminate the spurious hits, but this wrecks my ability to intentionally use techniques where fast double-hits are wanted
-'Home' angle of the hammer -- the angular moment with which the hammer moves with each kick.  Setting this too far away tends to make it hit the top of my foot (quite painful), and too short means its hard to make it work.

Other Thoughts:
I play barefoot, should I have a set of drum shoes?  Would that make a difference?
I want to use these also to play rock band thru the midi adapter (people report its fun) -- but the double-hits would seriously impair scoring ability, and I need a way to fix them!

I do this occasionally, and I find that it is a function of whether you are letting the beater rest against the head while you are playing. If you are like me, you may shift your foot on your pedal and it can register an additional tap unintentionally.

If you only just got it this Christmas, I would leave things alone for a few more months to adjust to the system and how you have it set up. If it continues to be a problem, then adjusting the electronic filtering might be a step once you know how you play.

Adjusting the tension might also help you play more deliberately.

I play in socks, for what it is worth. If you are playing in shoes, this might be another indication of foot-shifting.

Thanks for the reply! I do leave the beater resting against the sensor and never get spurious hits from that, it's when I hit, lots of the intentional hits have an additional hit (and trigger) in VERY quick succession to the first hit. I'm starting to think more and more its a technique thing. It happens most on gentle hits.
