Melodyne does so much more than people realize. I use it to tune bass parts, transpose audio, level vocals with respect to amplitude, and even do envelope-controlled flanging. Many of these applications are documented in the "Friday's Tip of the Week" thread.
After you install, you'll have the best results doing tempo detection if you select Percussion as the default algorithm.
The only real downside is Melodyne's color scheme doesn't fit too well your Aqua or Green Glow themes
