Yamaha DTXpress/DTXplorer/DTXtreme

Hello group,
It has been awhile since I've last posted.
Well here is my new problem.  Just yesterday while playing on my 
Dtxpress1, I noticed that everytime I hit the KP60, as I would 
release my foot, it would trigger a second sound.  So as a result, 
for every hit on the kick pedal, it would project two sounds.  It 
was quite frustrating, so I disconnected the wire at both ends and 
cleaned the tips.  Everything seem to work fine now but I would like 
to avoid this problem in the future.  What should I do?

Regards,
Mike

Mike,

Keep an eye--I mean an ear--on this problem for a while. The 
traditional flaw with the KP60's internal electronics was a tendency 
toward dropouts, which is the opposite of your case. The double 
triggers could be the result of too high a sensitivy/gain and too low 
a min. velocity, compounded by the beater making an almost 
imperceptible rebound on the KP60's rigid rubber surface after its 
initial impact. This action would be a non-event on an acoustic kick 
drum; if the beater makes slight contact with an acoustic head, it 
won't make any noise. But with electronics, any touch is liable to 
register velocity, depending on settings. Try changing your trigger 
parameters and making a conscious effort to move the beater away from 
the pad as soon as it strikes. You could also experiment with 
different beater materials to determine which are least likely to 
recoil, given uniform foot pressure. Hopefully, you'll come up with a 
mechanical solution before the electronics of the KP60 give out 
altogether (just kidding).

My problems with the KP60 started with "double hits" as you describe. This
actually seems to have been caused by  a broken solder connection. I
repaired this and it worked for a while, but soon failed again. Now Ed says
I cheated in my solution (I'm still bitter about this slur on my integrity
:-/)but what I did was build a Remo trigger as described at
http://www.electronicdrums.com/pads/pads2.htm. The back of this pad has a
1/4" threaded socket which allows it to bolt to the KP60 stand with a fender
washer. This requires you remove all the Yamaha stuff. The Remo pad stands
off the Yamaha stand the same distance as the Yamaha rubber pad. I have used
this for a year with absolutely no problems and the cost was about $20. I
believe the feel is superior to the rubber pad and I have more dynamic
range.

Creighton,

I'd forgotten about your double triggers (but not about your 
ignominy; you will have to live with that the rest of your life). 
We'll see whether Michael's problem turns out to be the same as 
yours. If it does, and he follows in your footsteps to solve it, 
here's hoping that he has the good sense to call the result a Remo or 
a DIY pad, not a KP60 (insert big ear-to-ear smiley face).
