Audio engineers, producers, and musicians looking for vintage Uni-Vibe character will be thrilled with the Blue Cat Audio PolyVibe, a powerful software plug-in based on the original Dunlop pedal with many enhancements and innovations that can simulate many kinds of vibes—chorus, phaser, rotary, or wah/vocal effects.

Using the original filter designs as a starting point, the plug-in lets you control the filter’s shape and motion to create new modulation effects, with two extra modes. It can also produce stereo vibe effects and all modulations can be synced to the host application. PolyVibes is compatible with Mac or Windows and works with most major DAWs using VST, AU, and AAX formats.
