I'm in need of several .wav, MOD-formatted, or soundfont samples (for about a dozen different remixes). I'm using ModPLUG Tracker as my creation method, because it's free, and I understand how it works, and I'm poor and can't afford commercial music composition software. Currently, what I'm looking for is the following: A sound that resembles a footstep, marching, something like that. A steel drum. A whistle, of the variety that might be heard in use by a referee or lifeguard (loud shrill noise, not like a person whistling with their mouth). Something (or two sounds taken together) which sounds like a heartbeat. A handclap. So far, I've been unable to find these sounds in the links provided, though I'll admit the possibility that I may have overlooked something. If anyone knows where I can find these, please let me know.
