This unique plug-in also allows users to sculpt custom LFO curves and shapes and comes equipped with dozens of presets to achieve desired results quickly.

Excellent plugin! Simple but powerful, extremely versatile, and makes it fast to get the pattern you're looking for and help something sink into the groove. They say you should spend money on good tools and this is an excellent utility for a lot of applications. I can't recommend it highly enough, it's one of my bread and butter plugins.

Plus, Xfer customer support is top notch. I used the contact form on their website to ask about an issue I was having and they replied (and solved my problem) in less than 5 minutes.

Great plugin, great company.

One of my favorites, and the new filters are just too good to be true

How does it compare with Cableguys Volume Shaper? Anyone?
