The Importance of Transients

The Importance of Transients

All music contains transients of some kind, whether it’s drums, percussion, guitars, or piano to name a few. Being able to boost or cut these transients gives you unprecedented control of an instrument’s presence and weight in a mix. With the Envolution plug-in, you can easily make a snare snap to the foreground, or add presence and/or distance to drums, piano, guitar, and more.

Two Sections — Total Control

Two Sections — Total Control

The Envolution plug-in offers Transient and Sustain sections, each with its own set of Attack, Hold, and Release controls. This amount of fine tuning gives you a wide variety of uses — from subtly cutting down room ambience on drums and guitar to completely re-imagining signals with extreme envelope shaping.

Frequency-Dependent Tweaking and More

Frequency-Dependent Tweaking and More

Both the Sustain and Transient sections feature a FREQ control that offers Tilt or Focus EQ modes. Tilt is perfect for more gentle envelope shaping whereas Focus mode provides a band-pass or notch response for more precise control. The Envolution also features a Warmth function that adds harmonic richness while also preventing output signal overload and a Mix control for added versatility.

The goat

This Just replaced any other transient designer I had. Makes them all sound like Toys!

if you need to use transients in a surgical way, from a cello to a ruined Drop Edm(!) , you should probably use Envolution. I am convinced that I have used my money wisely. Uad and Sonnox are a nice combination. Michele Ranauro (close friend of a singing horse, hired on Midjourney by mistake )

Surprised By the Results

I used this plug-in on drums to tame transients. I was amazed by the results. Nothing else has done the job like the Oxford Evolution! Great tool to have in your tool belt.

Great on Midi Drums

The best thing I have ever tried to make midi drums sound real. I use Groove Agent since it is part of Cubase. I use Envotution on all my snares, kicks and hats. The difference in night and day. Works well on other instruments put for drums it is a must

Tengo varios diseñadores de transientes y me resignaba a no adquirir este. Pero como tal es el más completo de todos y no me arrepiento de tenerlo entre mis principales herramientas.

Oxford Envolution my go to transient designer

Envolution is by far the best transient designer I have ever used. Works magic on everything related to drums. May be used as a creative tool for Dance music. All in all, excellent.

Sonnox Oxford does it again. This is the best transient shaper in the business. extensive control over attack and sustain with visual representation of what the processing is doing to the wave shape. The most perfect percussive sculpting tool.

Here is some new blood for your sound

If you want to experiment with original software, which you certainly don't have in your plugins library, this is probably the one to get you thrilled. I haven't worked much with it yet at the time of my review, but I plan to experiment with this software with different instruments. I'm sure you'll be surprised with the results playing around with the settings. If you want new blood in your sound, you're going to be served. A +
