In short, this plug-in is so valuable because it is so good at so many things. It's a fantastic delay, since you can fine-tune the character and action of the repeats to such a large extent. Chorus, flanging, phasing — it's all in there. The pitch-shifting is top-notch, which is no surprise coming from the company that brought the entire concept of digitally-altering pitch to the masses. The routing, filtering, distortion, and modulation capabilities are nothing short of what you'd have access to with a robust modular synthesizer setup. Yes, the GUI is a bit complex, but time invested in mastering it will definitely pay off once you dive into the depths of this very powerful processing tool.
