Yamaha DTXpress/DTXplorer/DTXtreme

Hello all,

I have the origiginal DTXpress I kit that I'm looking to upgrade the 
brain/sound module. I'm looking at the DTXpressIII brain as a 
replacement and also the Alesis DM Pro with my pad set. I lso have 
upgraded dual pads for the snare and hat along with dual trigger 
cybals and bell pad.
Any problems of incompatatabiltiy?

Thanks, Steve
