Pad Pressure Adjustments: Important... these adjustments should only be made if you are having pad problems and have already tried the software adjustments, i.e.. Pad Threshold. If your rubber playing surface is not laying suitably flat (causing triggering problems), you may need to adjust your rubber surface.  Please read this     entire information sheet before performing any adjustments. Before you adjust the allen-head tension screws on the frame to adjust the tension on your trapKAT rubber, there are several things you should try first.  
Adjusting the allen-screws is the last thing you should try and is rarely necessary! First, a little explanation of how an FSR sensor system works will be helpful.  Over such a large expanse on a surface whose first and foremost goal is to feel and respond great, the rubber (and to some extent the FSR sensor) needs to “breathe” and be able to shift and adjust to changes in temperature, humidity, and pressure. The rubber can’t be tightly clamped down or adhered in one place.  The rubber must be a bit free to move and adjust - to be able to stay flat and in close contact with the FSR sensor system underneath it even with the repeated intense impacts that a drum controller experiences.  The rubber is designed to self-adjust and be able to shift and move a bit. Rubber not laying flat?  After transporting your trapKAT from one place to another, your rubber may not lay as flat as it normally does.  If your frame is properly adjusted so that the rubber isn’t compressed by the frame, the rubber will generally self-adjust after a half-hour or so on its own if you place it in playing position. To speed up the process, use your drumstick as a rolling pin to coax the edge of the rubber back under the frame.  In addition, you may try grabbing  one or more rimPads and pulling it outward toward the outside edge (in the area where your rubber isn’t laying flat).  Don’t pull up, pull horizontally - parallel to the main pad surface.  This should push the rubber back under the frame so that the pads will be pulled flat again. If this isn’t providing satisfactory results, you should loosen the allen screws in the area and repeat the above steps to position the rubber back under the frame.  After you have repositioned the rubber  to your liking, you need to re-tighten the allen-screws. When tightening the allen-screws it is important to avoid two problems:
1)  Overtightening the screws will damage the sensor plate underneath the rubber ifthey are tightened too far.  This will void your warranty.  You can tell whenyou have gone too far, the rubber will start to bulge as you clamp down on the rubber.  The rubber must be free to move a bit under the frame, so you don’t want the frame to actually compress the rubber.  Call us if you are indoubt (413-594-5190).
ng to your FSR idle levels.  You’ll probably find this interesting as well as fun! To get to this new screen:
1)  Hold down the Kit Edit footswitch
2)  While the Kit Edit footswitch is depressed, hit rimPad 20 (the rimPad to the immediate right of the display) three times.  On the first hit it says “No Function” - ignore that and keep going.  With the second hit you see the actual settings for your hihat pedal.  On the third hit you see the idle level of Pad1

This screen shows you the “idle level” of all 24 of your pads.  This “idle level” is a measure of what the internal computer sees from your pads when you are not playing - when they are “idle”.  As you know, FSR is sensitive to very light playing or pressure.  Therefore, even the pressure of the rubber itself can show up.  That is OK - the software is designed to take care of small constant pressures.  This is what we call the “idle levels” of your pads.The top row has all 14 rimPads.  The first 10 are rimPads 15 to 24.  These are the rims that start on the left corner and curve around the back to the right corner. The last four on the top line are the four front rimPads 11 to 14.  The bottom line has pads 1 through 10.  To identify which pad is which, pick a pad andpress on it and watch which number on the screen rises when you press it. (It is normal for there to be some jitter or fluctuation in the numbers around some specific value - from 1 to 0 to 1 to 2 to 1 etc.) As you adjust the tension on the rubber with the allen-screws, make sure you are not raising the idle level of your pads too far.  Any idle level of 5 or lower can generally be handled by the internal trapKAT software without false-triggering.  If you have a 6 or higher you should loosen the allen-screws by that pad. To exit this screen and return to Play Mode, press the Kit Edit footswitch and release it. When adjusting the tension of your rubber with the allen-screws you need a balance between making the rubber lay flat and keeping the “idle level” of the pads low. If you would like help from us when you feel a need to make this kind of adjustment to your trapKAT, feel free to call us at 413-594-5190. We would be glad to  help you get the most from your investment. See Appendix A in the trapKAT manual.
