on the Internet" and nearly _ANY_ patent involving software. Just like all the ridiculous patents for ". A well understood property of physics applied to X. In fact, if you google "hall effect patent", you'll see a number of ridiculous things people have patented implementing what effectively is e=mc2. That was his first solution to the problem - which tells me the US PTO granted a patent that doesn't pass the 2 major tests of novel and non-obvious.
After I explained which part of the kit a hihat was, he told me about this interesting behavior of perpendicular magnetic fields and how you could easily use it to detect hi hat states. I had asked a buddy who does EE professionalls how he would make a hihat controller. On a semi-related note, I'd be interested to talk to a patent attorney regarding the patent on the Hall effect sensor. If they used a mechanism that provided _zero_ resistance to existing hihat assemblies (.I'd think making the cymbals heavier would be an obvious solution), it would work far better. Its only purpose is putting pressure on the HH controller. I think in their testing Alesis must have just worn the hell out of the spring. Don't adjust the height as the whole point is to make sure the spring keeps constant pressure on the cymbals and raising the cymbal too much will put you back to square one. just remember put the washer on the spring, then lay the cymbal on it and crank it down. Anyone with strike hi hat I urge you to give it a shot. And what do you know when I change the settings and do the calibration it actually works and makes changes to the feel. And seriously with just that washer this thing is flawless. If you don't have one you can use the washer off of one of your wing nuts but note it will be a bit too thick and you will want a thinner one but you can use it and it will work just the same it will just work. You simply lay that on top of your spring assembly and then place your cymbal on that and tighten it down. I did a lot of experimenting and found the best washer is actually the felt washer that your lower cymbal sits on. Turns out the spring that separates the top cymbal from the bottom cymbal is too short. Looks like a solution to the whole strike hi hat debacle has been floating around for a couple weeks and just now are people catching on, doing it and finding it works. So this needs its own thread so it doesn't get lost.
