Battery 2 With Gb/le7 Options

[moneytrain]

hi,
i was wondering whether you could use battery 2 with garageband. is there an option that you can assign different samples to different keys on the keyboard and create loops?
could you use it with logic express? as there is no ultrabeat in express, could you load the samples into the exsp-mkII player and create loops?

thanks a lot in advance,

(p)

my formulations may not be the best, but i'm still a total newcomer and haven't even composed a single song.
