Yamaha DTXpress/DTXplorer/DTXtreme

Hi there,

I have a DTXpress II and there are some problems with the rim zones
from the TP65S snare. I can't play the rim sounds when I want, this
happens very involuntarily. In most cases, I only hear the normal pad
sound when I hit the rim zones, but sometimes when I play straight on,
it happens that there is a rimshot to hear. But when I heard it, I can
play it easily about 5 times. After that, the rim is unplayable again.
The same on other inputs. 
I'm very confused. Is it necessary to hit an accurate angle, e.g. rim
and pad the same time or should it work when I just hit the rim?

I checked the settings on the module and everything seems to be just
fine. The rim ounds are set up properly, stereo cable used.

I don't know if it's a module or a pad problem, but I think it's the
second. Do you recommend doing a factory reset? How can I save my
entire settings via MIDI as dump?

Should I try to open the snare pad and check the cables or should I
just replace the entire pad?

Thanks for your help,
best regards,
Flynn

You need to do some swapping around to determine if it is the pad. 
Swap the cable with another to make sure it isn't the cable.  Try the
pad in another input (inputs 2, 6 and 7 are 3 zone on the DTXpress
II).  While a factory reset would sort out any things you may have
tweaked, try picking one of the preset kits, and the preset trigger
setups if you aren't using those.  Make sure the input is setup for
the TP65 (I think you have probably already checked that).

It does sound like a pad problem; either a bad connection or faulty
rim switch.  If you have a two zone pad, you could try that in the
same input and see if that works reliably to confirm that the module
is ok.

Thanks, Keith for your fast answer.

I already swapped the cable and used it with the HiHat controller and
it works just fine and also tried other inputs and it's the same
problem, also with the preset trigger setups (TP65S on input).

I also think that it is a pad problem. When I insert the plug into the
pad only half way, I can play the rim sounds just fine with the normal
pad surface (not the rims though). The question is now if the socket
is only canted inside or if the rim switch is really broken. 

I opened the pad a little bit but didn't open it completely (I worry
that I can damage the pad completely or rip something off beacuse I
can't afford a new one at that time). Both rim switches look ok, but
pressing on them with the finger and hitting the pad surface doesn't
make anything better. Another option of course would be the cable from
the rim switch to the circuit, perhaps a hairline crack in general?

I don't know if you have access to a multimeter, but if you do, the
rim should be just a few ohms between the ring and sleeve of the
connector when pressed, and 1k or 10k (I cannot remember which) when
you press the third zone.

It is not possible to press the rim and hit the pad - if the rim is
permanently shorted, the module ignores it - it expects the rim switch
to close within a certain time of the pad being hit.  I guess it works
this way due to the need to choke the cymbals.

I think there is some glue which could be stopping you getting it
apart, but there is a risk you could damage it.  What until it's
really broken.

If you can live without the rim for now, just use a mono cable - that
will ignore the rim switch.

Hi Guys, I seems to be having exactly the same drama with mine.  My 
Snare is a TP80S.  I bought the kit 2nd hand and have always had this 
problem with it.  Sometimes it works sweet, sometimes not.  
I will try the mulitmeter exercise this w/end and see how that goes.
I've already done the whole factory reset to no avail.

Cheers,
         Glenn.

Glenn,

Don't forget to try swapping cables, just in case.
