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 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 within a few seconds.

• Volume envelope
• Low cut filter envelope (with resonance)
