Greetings! Background: 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!
