Yamaha DTXpress/DTXplorer/DTXtreme

Hi folks,

I�ve played around with my new set nof for a couple of days- only the
hihat is still p...... me off! I cannot understand why Yamaha has
released such an unsatisfying product! There�s almost no continuity in
the pedal, I might as well use a switch! This in relation to how good
the rest of the kit is makes it even worse!
I`ve just talked to a guy at drumtec (my german dealer) and he`s told
me that the RHH130 controler itself has 7 resistors inside (instead of
the normal Yamaha hh-controler that have only 3) which should at least
give the drummer a sufficient sensibility for playing a slightly
opened HH? So where�s the problem? Yamaha claims that the DTXpress3
has a continuous HH- looks like the brain is not understanding what
the controler is telling him- or am I wrong in this?
The guy at drumtec told me that it`s also the same sh.. with the
DTXtreme, so no solution in getting that brain either.
Couldn`t this be solved with a sort of electronic interface? Some
device that translates the input from the RHH130 controler to the
DTXpress brain? I�d really like to hear comments from the electronic
technicians in here!
Thanks already in advance,
Wolfgang

I don't know about the RHH130, but the standard pedal has 6 resistors,
a capacitor and a diode in it.  The way it is wired gives four
resistance values to the tip, plus open circuit, making 5 different
settings.  On my DTXpress you can hear those differnet settings.

Well, I would be happy to try to help but my hihat works fine. 
Assuming there isn't a fault with either of your components then it
must be setup - euther physical or electronic (i.e. settings in the
module).  I don't have the RHH130 to play with to see what the problem
is.  If you have access to a multimeter you could try to measure the
resistance to the tip of the conenctor when you press the pedal. 
Other than that, assuming the module is not faulty, you need to adjust
 the HH OffSet parameter. 

Hopefully someone with the RHH130 will chip in with their settings to
help out.

Hi Keith,

I`ve tried out all couple of settimgs to that HH offset parameter, but
it just sets the point where the modul starts to play the open sound
instead of the closed sound. My problem is that I`m lacking everything
in between! I`ll measure out the resistance tomorrow, that`s a way to
start with at least- although I don`t think it`s the case my RHH might
be faulty?
Did you ever measure the resistances of your HH controler? Would be
interesting to compare!

The way it should be is that the module should start playing the open
sound as soon as I release just a little bit of pressure on my pedal-
but it should play the sound with very little decay and then it should
continuously increase the decay to full while I release the foot
pressure even more. That way it should come close to an acoustic HH-
don`t you think so?
The HH controler should control the decay value whilst opening up the
HH- but my stupid thing doen`t seem to know this..   ;-)

Wolfgang,

The resistances should be:

150k (foot down)
160k
207k
357k
infinity (foot off)

I measured mine and they are within 3k of those values with the
exception of the infinity which is around 6M

It is surprising that the foot down resistance is so high and the next
level is only a small change, but it works fine.  For information ,my
HH OffS is -10.

I assume you are using a stereo cable?  Two other resistors, a diode
and capacitor connect to the ring of the jack and they are important
for the splash sound, but a mono cable usually stops the pedal working
altogether.

Keith.

Hello Keith,

I`ve measured the resistance today and I have the same
values than you- but I`ll find it almost impossible to
get the readings between 150k and 350k! I cannot hit
and hold them even for a second, neither with my feet
nor with my hand! The only value in between that I`m
halfway capable of hitting an holding is the 350k,
next will be eternity.
Even stranger when you assume what the guy from
drumtec told me (7 resistors...)?!
I`ve also found another setting in the drumset overall
parameters that is named HH sensitivity, played around
with it but didn`t do much diference at all.

greetings,
Wolfgang

Wolfgang,

Unless someone else can shed any light on this problem, I would
suggest maybe you have a faulty HH controller.  I don't know how the
RHH works, but the HH pedal progressively shorts out the resistors to
give the final values (it actually consists of 150k, 10k, 47k & 150k
resistors in series).  Maybe you should return it as faulty?

Keith.

My RHH130 had pedal problems out of the box, I had to lean most of my 
weight on my foot to -sometimes- get a closed sound.  I had already been 
reading the group so by the time my kit arrived I was aware of possible 
HH defects.  This message was the basis of my solution:

http://launch.groups.yahoo.com/group/DTXpress/message/8838

When the replacement arrived, I tested with the old one to confirm that 
it hadn't mysteriously fixed itself and then swapped in the new unit 
without making any other changes.  The replacement felt completely 
normal as opposed to the original that had me doubting the intelligence 
of my purchase.

First thing: Many thanx to all of you who have contributed to this thread!
So obviously I`m not the only one who has complained about this
matter. Right now I`m not quite sure what to do? My special kit is
brand new out of the box and it`s always hard to believe that some
part of it won`t work properly right from the start on. But now I`ve
learned that this has been the case with other kits.
I`m an electronic technician ( or at least that was the profession
I`ve learned 20 years ago...lol) so I could take the hihat apart and
check wether there�s something bad or not- but I`d void my guarantee
if I`d do so! So maybe it`ll be just smarter to try out another RHH130
and see wether it`s different from my unit or not?
What I did today was to turn the little output pot on the back of the
RHH130 to 12 o`clock position- this made it a little bit better, but
I`m still far from being able to play slightly open hh sounds if I
want to. Right now when I release the pressure of my left foot
sometimes the right sound will appear- but I better do not breathe no
more and freeze any moves of the lower parts of my body just to keep
it for a little while- not the easiest exercise......

Tomorrow I`ll call my dealer and see if he`ll be willing to send me
another RHH130 to crosscheck it- I`ll keep you informed on my progress
(if there is any)!

CU all,
Wolfgang
