Lumina Delay is the first effects plug-in to be released by Mountainroad DSP, a company set up in 2021 by mix engineer Serge Courtois. Rather than relying on knobs and buttons, the plug‑in allows users to plot delay taps and control their parameters using an intuitive visual interface.
Much of Lumina Delay’s GUI is occupied by a grid-style display which is divided into three lanes: Volume, Pan and Hi/Low. Delay taps can be drawn directly onto the grid, and there’s no limit to how many can be added; users are able to create anything from simple slap-backs to intricate patterns that span multiple bars, and it’s even possible to add more than one at the same location and apply different parameter values to each of them.
The Volume lane offers up to +24db of boost and -100dB of attenuation on each individual tap, and can be controlled either by dragging the dot vertically or right-clicking and entering a specific value. The Pan lane, as you might expect, allows different pan values to be applied to each tap, making it possible to create detailed panning effects that would be difficult or impossible to create with traditional delay parameters. Low/High then offers control over low- and high-pass filter settings, again on a per-tap basis.
