Also, camelphat is almost too good to be free. I've seriously used this lil compressor ahead of some proper expensive ones and instead of hardware cos when it works it's really sweet. Doesn't work on everything, but try it out. Great as a drum smasher, or you can put it on a bus and get parallel action going on - it can do some pretty twisted stuff to the decay of drum sounds. The filter is also useable and it's got a nasty distortion too.
