    Thanks for posting this "one and done"! I have a TD-25 KV and the snare hot spot is annoying. I have done a few things to improve it, put it is still a problem.

    I am going to dig into the links provided and see what I can do.

    I have been toying around with my settings for the ATV aD5 and found that these parameters dramatically reduce hotspots on my Tom 1, Tom 2, and floor Tom (all Roland PD with center- mounted cones). I've also REALLY tightened those mesh heads, which helped a lot.

    The only downside that I can see is reducing the sensitivity makes the toms less likely to pick up subtle hits or the stick-drop-bounce thing. For my purposes this is fine and as you can see from the graph on the left side, my hardest hits are not at the top range (ff).

    Definitely fixed in the TD-50.

    For me it was running a 4th tom on a TD12 module, so I had to use Aux 1 and it was set to cymbal by default. Once I set it to PD120 pad, no more hot spot!

    keep at it...it's do-able.

    Why stuff around with patches? You can dial out the hotspot with a little research. It's well documented here...
    And, yes, I would think (as Jman experienced) that it would stuff PS up.
    PS works by reading the amplitude of the first half of the waveform over time from the head piezo. The further from the centre, the waveform changes shape from a centre-strike waveform.
    Place anything on the head that alters the head piezo waveform, and the module will misinterpret the waveform as a change in head strike position.
    The patch will cut down the flex of the head (thereby varying the signal from the piezo), most likely making the module think the head was struck further from the centre.
    It's relative, according to your adjustments, but if you want to remove a hot-spot, curve and compression work best...

    That's good to know Jman, thanks! I would think the diameter of the patch makes a difference. Maybe the material/ thickness too? The evens patch looks much larger than the small rubber patch I ordered today. These are really small, barely larger than a thumb print. Exactly what I was hoping to find, just big enough to dampen the hot spot. I'll definately post the results.

    If you are going to start putting dots or patches on top of your heads ...... One thing you should check closely is the affect the patch has on positional detection. I once started having problems with Positional Detection on a snare that had been working flawlessly. I took the thing apart, changed out piezo, cone... etc. etc. and still the same result. Later I was looking at my snare and remembered I had put a thin drum head patch like this one on top to give me extra protection in the center area that gets the most wear: http://www.drumsonsale.com/evans-sin...ck-p-1881.html
    Yup, turns out that single little patch totally messed up my PS.

    That would be bad, lol. Thanks!

    I make my own kick patches from mylar heads.(usually ones left over that I have used the hoop for my DIY mesh projects) I take the head and cut out the black dot....apply KRT(Killer Red Tape) to the back.....and then stick it to the kick mesh. Works great. It is of course very thin being made from an acoustic head so if it's cut down to a small enough "dot" to just cover the "hot spot" (1 inch...maybe smaller?)....I don't see why this would not work in the same manner as the tape you experimented with...and it should look nice too.

    but with an additional horizontal strip.

    Obviously it must not affect rebound though. I suppose that's the real trick.
