a hi-hat

This one is just a little bit of the crash sound plus some filtered noise. Right now I have the subpatcher at 16x oversampling, but you can bring it down all the way to 2x or something if it uses too much CPU; I often do that in compositions. It just sounds a little grittier (not necessarily a flaw) when there's aliasing.

You can get a whole variety of sounds by messing with the parameters. E.g.: ogg mp3
