soundfont? gigastudio? at the NSKit

[bilibilek]

i downloaded the NSKit sample drum sounds. i did it in wav format so i've got 14 different levels of snare sounds, 16 levels of hat sounds etc. all in different wav files.

as long as i'm using leafdrums (even though it is very practical) when i'm trying to do some partition with an increasing attack it gives me a hard time. i have to use at least 3 of the files in different channels.

there must be a different way, isn't there? what are those soundfont and gigastudio formats in that site? which program are they run with?
