ah okay sige bootcamp tayo.
the *.dll file you downloaded is a VST instrument plugin which will require a host/DAW like reaper.
http://www.reaper.fm/(peeps, uhh kung may alam kayong absolutely free na midi+wav DAW software suggest niyo na)
reaper is not free pero i think i've heard people say that it will function past the trial period (di ko sure). if the trial period portion turns you off, siguro pwede ka maghanap ng 'other versions' sa 'sipa-pwet' or some other site that hosts files provided by people with eye patches, peg legs and a parrot on their shoulder *wink*.
eto yung general idea (di ko alam specifics sa reaper eh, sorry):
- after installing reaper, you need to load said *.dll (tromine-gt). sorry di ko kabisado reaper baka someone else knows. *help naman*
- you create a midi track then configure it so that it sends midi information to the VST instrument you loaded.
- in the midi editor, create the beat you want.
hehe teka isipin ko pa, wait...
