To me, this is not the ideal way to do it. Things to consider:
1-using midi to replace a hihat seems like a better option(using a drum VI such
as Superior Drummer 3)
2-random is not really what you want. Its more likely that you actually need 3-
4 levels at most to cover normal player dynamics.
3-were all your 100 or so hits played by a person? If not(and they are all
exactly the same volume), then I would start over and record a person
playing.
4-how about loading some hits into a sample player(Structure?), and
playing/triggering with a midi controller where you can play with dynamics?
5-since there's usually 4 ways to anything in digital, what's the end goal?
Maybe there's another method that would get the desired results
