Kuvert

Envelope Shaper

A groundbreaking way of looping effects.

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.

Features

  • Volume envelope
  • Low cut filter envelope (with resonance)
  • High cut filter envelope (with resonance)
  • ”Glitch” envelope (alters timing)
  • Delay send envelope (with tempo synchronized time, filter and feedback
