This was the first plug I ever tried by Tweakbench, and to this day, it's still my favorite. Pudding will take any audio you feed it and mutilate it and spit it back in your face and sneer and jeer at you. Amazingly, most of the time you'll enjoy what it spat upon you. The primary ability of this plug is of course it's granular shredding power. Don't expect Pudding to make pretty things, it hates to do that. It likes to take pretty things and make them weird dangerous things to excite your tracks.
Pudding allows complete control over all aspects of the grains, such as pitch, length, window, grain rate, etc. Due to this magnificent control you can really manipulate the sonic palette till you have just what you want. Or, if you're a lazy bastard like me, you'll love the Random button, which'll either create a great stream of grains or blow your monitors up (watch those levels!).
There are a lot of self proclaimed "extreme effects" out there, but this is one plug that's not only extreme, but actually useful. And that's why it's still sitting on my harddrive. Anyone can make a plug that implodes and discombobulates audio, but to enable that output to be a truly useful affair takes talent. With plugs like Pudding, Aaron shows he's of the latter league.
