Yamaha DTXpress/DTXplorer/DTXtreme

Hi there,

Alhough I have some experience in acoustic drums (mostly banging) I'm
a total newbie in this e-drums field, but not in computers. Now that I
wanna practice again at home, I'm searching for a e-drums kit and
stumbled across Yamaha. DTXreme2 looks very nice, and if I'm not
wrong, it's relatively better equipped (comparing it to Roland TD8).

I understand I can program some songs with both (DTXpress & DTXtreme),
and connect it to a PC via MIDI. What I couldn't figure out, however,
in those endlessly boring marketing brochures is:

- Can I plug these kits to PC via USB or Firewire, as in MIDI?

- In any case, has anyone practical experience on processing the
output, say, applying reverb, etc. on the computer? Do I need a
powerful PC to do it realtime? I see some ppl who have laptops beside
their e-kits, is this what they do?

- Finally the biggest question: Can I replace and/or combine other
sound modules and/or pads if I purchase, say, DTXreme2? In the future
I want to be able to use additional pads, cymbals, and if needed, a
better soundmodule and such.

Thanks for any information,
Cüneyt
