Yamaha DTXpress/DTXplorer/DTXtreme

Hi Guys

I currently have the standard Dtxpress II kit and based upon your 
recommendations I plan on buying a Pintech ConcertCast Pad.

Do I need any extra hardware to connect it to kit? I want to keep 
using the current snare pad - so do I need anything else except the 
pad itself?

Thanks

Yoav
