Yamaha DTXpress/DTXplorer/DTXtreme

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.. 
:-)
