How many different hi-hat patches can be assigned and triggerable via a sampler?

[DRulz]

I would like to try to achieve a full working hi-hat - one with pedal splashes and also closed hi-hat sounds.

On the same note, can I assign a snare cross stick patch on the snare and trigger via midi? Can I assign a rimshot as well? How about cymbal chokes?

Just a note, I will be triggering via a software sampler Battery and also will dump this patch onto a hardware emu e6400 sampler.

Thanks.
