Made this a while back for my brother (he wanted essentially exactly what you were talking about). It's based on SoundLump, from the Jitter Cookbook series.
--I'm not sure if it needs any externals, and it's horribly messy. Never really planned for anyone to actually see it's guts. One downside is that it does not clip the lines 'behind' the foreground lines - so it's not exactly like the Joy Division cover, but it's pretty close.
