Yamaha DTXpress/DTXplorer/DTXtreme

Hey all,

I will be getting rid of my Roland td-5 in the next few weeks and plan on picking up a dtxpress.
had a few questions that you might be able to answer.

does the module have a metronome?? 
I am assuming so.

and how many inputs does the back have?
Currently my td-5 only has 5 drum inputs,  1 HH and 2 cymbals.

Thanks

Joe
