Envelope Shaper

macOS/Windows $39.99 and iPad $7.99

A groundbreaking way of looping effects.

Stay in the loop.

Kuvert defines a whole new way of dealing with effects. In short, Kuvert allows you to draw five different envelopes. These envelopes control different effect parameters, and can be drawn freely or onto a grid. The envelopes are looped, while the incoming audio isn’t (unless you’re feeding it looped material of course). This is a powerful & fun way of altering your sounds to reach a whole new level, sometimes not even recognizable! Thanks to the looping nature of the plug-in, it will fit very well into any musical context. One way of using it would be to revitalize any looped material (such as beats) within just a few seconds.
