Yamaha DTXpress/DTXplorer/DTXtreme

hi all from Italy.. 

i have a complete DTXII set (with rubber pads).

I decided to customize a "Wood Dixon Snare" mounting a mesh head on it..
now i need to buy a DUAL TRIGGER to play this snare on my module..
 
well.. many vendors says that most part of the existing triggers do
not work properly with Yamaha modules... how possible ??... surely i
don't want change my module with ROLAND...

Can You suggest me a working DUAL(centre + rim) TRIGGER ??...
(a link to buy it on internet will be well appreciated)

Thanks and up Yamaha.

Greetings, Gianluigi.

Assuming you have made a snare with two piezos you have two choices -
use two inputs on your module or build a DTXpander circuit which will
convert the rim piezo signal into a switch signal.  See the files
section for the circuit diagram.

While a Roland is an option, the cheaper Rolands are the same as the
Yamaha - they use a single piezo and rim switch rather than two piezos.

Thanks Keith for the prompt reply...

to be honest i was not thinking about "piezos" to trig my Acoustic
Snaredrum.. but to a "CLAMP TRIGGER" (is this the correct name ??)
the best example is the totally red type from DDrum.. do u remember
it??... well.. why a trigger like this wont work with my DTXII module??..

coming back to "piezos"... it would be a real cheap solution..
and i could use 2 channels on my module.... but piezos works properly
with DTXII module or i need to reprogram each channel once installed ??

Last thing.. WHERE TO STUCK PIEZOS ??
1 directly under the mesh head and 1 on the wood board of the Snare???

sorry but it's my first attempt in this field.. 
:-)

I assume you mean something like this:
http://www.ddrum.com/drumtriggers.htm

Yamaha do some as well:
http://www.generalmanual.com/Musical-Instruments/Yamaha-DT-20-Snare-Drum-Trigger.htm

The Yamaha module has settings for the DT series triggers, if that is
what you use.  I don't know what the output of the DRUM ones is like.
 However, if you want to get a rim sound as well as a main pad sound
you will need to use two inputs unless you use the DTXpander.  The
Yamaha DT series triggers have a piezo inside them.

If you use the Yamaha DT series all you should need to do is to edit
the trigger settings for that channel(s) to use the "DT Snare" setting
(see page 12 of the DTXpress II reference manual).  All the kits can
stay the same, although depending on which input you put the rim shot
sensor you will need to edit that.

If you want to put your own piezos onto a drum, it would be worthwhile
