MIDI and electronic drums

Some questions for anyone who’s got some first-hand experience:

I’m thinking about getting a DTXpress set of maybe a Hart Prodigy -

- do they have MIDI out?

- do they have more than one MIDI out?

-do I need more than one MIDI out to create multiple tracks (a separate MIDI track for each trigger, or a separate MIDI track for each group of triggers)

thanks!
