VSS™ INTRODUCTION
Overview of the VSS™ Reverb Section
On the opposite page you have a graphical overview of how the VSS™ Reverb algorithm is
constructed. To fully utilize the possibilities of Early Reflections and the Reverb tail you should
understand the relationship of these sections, and be able to control the most important parameters.
As this is just an introduction on how to work the VSS™ Reverb we will only direct your attention
to a few of the sections. For explanations of all the parameters you should refer to the complete algo-
rithm descriptions on the following pages.
Please note that the illustration only covers one Engine. So the M3000 has two of the illustrated elements.
Hearing the terms ”Early Reflections” and ”Reverb tail”, might lead you to believe that these two
sections are placed in a line, with the Early Reflections first followed by the Reverb tail section.
This is as you can see not the case. The two sections run parallel.
Pre Delay versus Rev Delay
The first two points we would like to bring to your attention is the Pre Delay and the Rev Delay.
The Rev Delay moves the Reverb tail away from the source material. This is listed in many other
reverb units as Pre Delay. In the M3000 the Pre Delay is the parameter that moves the entire Reverb
section; Early Reflections as well as tail. We recommend using the Rev Delay as your first choice
when moving the Reverb tail from the direct signal.
The Early Reflections take place in the first few hundred milliseconds and is what you hear before
the more randomly calculated tail. Therefore the idea of delaying the Early reflections with the
Pre Delay parameter should be carefully considered, and as the Early Reflection patterns are of a
very complex and precisely calculated structure, adding too much Pre Delay can give you a feeling
of less precision and might sound ”out of phase”.
Mixing the Reverb Out Levels
We recommend careful considerations concerning the level parameter on both the Early Reflections
(Early Lev) and the Reverb tail (Rev Lev).
To emphasize either the Early Reflections or the Reverb tail, try setting the Early level and the Rev
level with a difference of 6dB.
Modulation of the Reverb Tail
The M3000 is capable of producing an optimal precise clean Reverb tail. However in some situations
you might experience that the tail is too clean/perfect. This is why we’ve added the modulation
features. With Space Modulation and Reverb Modulation, you can tweak the tail in different directions.
As shown in the illustration the Space Modulation is a separate block that works on the very Output
of the Reverb, where the Reverb Modulation is an integrated part of the complex reverb
calculations that works specifically on the tail.
