some more things you can try:
a random lfo (MD) -> Sample loop length/start (battery)
or random lfo (hold) -> filter/eq
or both... or even more!
Look into the option Cycle round robin (or somethin' like that) as well.
This gives you the option of triggering a different sample pad from the same midi-note#, it cycles thru them as the name does suggest.
I really like Battery2
But i think it's a pitty that the Modulation option "loop count" isn't there anymore (it was in battery (1)). But options as compression and filtering make it much more easy to mix.
