Barry’s Toolkit: First Look At The New Lexicon Native PCM Reverb Plug-In

Real-Time
The real-time analyzer in the center of the upper half of the GUI is a spectacular, three-dimensional multi-band tool for actually “seeing” the reverb sound build up, play out and evolve over time. The time line runs from right to left with reverb level represented vertically.

Once a reverb signal is present, different color-coded audio waveforms parade across the screen. Each of the moving waves represents a frequency band from 50 Hz to 12.5 kHz with the lower frequency bands in the back and higher frequencies in the front.

I found the RTA edifying—perfect for adjusting the Early Reflection and Tail EQs, predelay, Bass RT, Reverb Out level and Size parameters.

Being a summed mono display, for stereo parameter settings rely on your ears, as you should for all adjustments. The RTA confirms what you are hearing and is mesmerizing too.

There are also two other ways to “read” the reverb sound: a more conventional and colorful 2-D spectrum analyzer bar graph and a linear moving amplitude waveform display.

The manual points out that these dazzling displays require additional host DSP so after impressing that client watching over your shoulder, save some DSP and turn them off before closing the plug-in’s window.

Reverb Controls
The remaining lower 2/3 of the GUI is devoted to the control faders. I found these faders to “mouse” very responsively without delay or glitching like other plug-ins.

Depending on the reverb plug-in you’ve called up, this section can be populated with up to nine parameter faders.

I liked that the most salient and useful faders are shown and for the most part, similar parameter faders from one reverb plug-in to another reside in the same slot—such as one of the most changed parameters—RT (reverb time).

For the most part, there is little need to drill deeper than this page.

There are so many presets in each Category, I found toggling through them quickly gets you close to what you want and then a quick fader move or two gets you all the rest of the way there.

Each parameter fader position is named and has a value box for manual entry. Clicking on Edit allows any of the parameter faders to be re-tasked or changed to control any of the other available parameters by using the pull-down menu under the Modifier button.
