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.

Great plugin.

This is easily the best sounding transient designer that I have ever used.

Works even at extreme settings

I have used a competition version with more options but even the slightest of increased attack settings produced nasty clicks with that one . Envolution sounds good even under extreme settings which is what I use it for occasionally especially on Bass and Drums. The EQ could be a bit more flexible as far as I'm concerned. Great plugin to deal with boominess/muddiness in Console from the get go.

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 )

Great Transient Designer

Awesome alternative to Spiff, SPL, Smack Attack etc etc etc. It certainly has its own flavour and definitely deserves a place in my tool box!

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.
