Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,

I have not messed with this much, but I want to get a non-Yamaha
mesh-pad for my snare. In any event everytime I see that some one has
added one they set them up using the dual signal aux. But since I am
utilizing that for additional cymbals and since the the snare input on
the DTXpressIII is used with a 3 zone pad, can't you split that into
(at least 2) using adaptors? That way you could add a dual zone mesh
snare.

My DTXpress kit is only half a year old and I am begining to think I
should have went with V-Drums. The Yamaha stuff seems too propriatary.

In input would help.

I have the Pintech Concertcast dual zone snare and have used it on my
DTXpress using my expander box instead of using two inputs (see
DTXpander in the files section).  I like the mesh snare for expressive
snare work but I am not so keen on smashing my sticks to bits doing
cross stick sounds on the metal rim.  While it has been suggested that
I put some pipe lagging around the rim or something similar, if I
wanted a home made look I buy a wooden shell snare and convert it.  So
I often swap the snare depending on what I am playing.  Also, the mesh
snares are not so robust (my drum kit gets thrown in a car once a week
and the snare ends up upside down in the passenger footwell while
still attached to the snare stand - I wouldn't like to treat the mesh
one like that).

Sorry, but what is the DTXpander? The files related to it on the group
site are schmatics that I do not understand. Is it something I can
buy? Or do you have to make it? And does it allow you to split the
signals (IE an 3 zone pad in jack could handle 3 single pads plugged
into it with out signal bleed)?

The DTXpander is something I originally designed to allow people to
plug two pads into one input (eg a tom input) to allow expansion of
the kit using the unused stereo inputs.  For example, all the toms are
single zone, but the inputs are dual zone, so it allows you to add
three extra pads by "sharing" the tom inputs.  The extra pad will
appear as the "rim" input of the tom.

It has limitations because you cannot get both the rim and main pad
sound simultaneously, so it needs careful selection of what you use it
for.

Another use is for interfacing drums like the Pintech Concertcast dual
zone snare.  This uses two piezos rather than one piezo and a rim
switch, so would need two inputs on the DTXpress.  With the DTXpander
it can use one input.

Originally I made the circuit available for non-commercial use so
people could build their own because I didn't have time to make them.
 Since then I have made a PCB and built a few for sale for people who
are not confident in building their own.

OK, makes sence. I definatly do not have the expertise to put that
together. Not without a total step by step parts and how to guide.
What do you charge when you build them?

Thanks, I am glad it is useful.  I am an electronics engineer - hence
my interest.  Just don't ask me anything about drumming ;-)

I will send you a personal email - it was never my intention to use
the forum for selling things which is why I posted the schematics here
(and the edrumforfree site and the DIYedrums forum).
