By looking at the service manuals and schematics of the 480L, Relab were able to observe the behaviour of all the analogue components and model, with relative ease, “everything from internal clipping to quirks in the feedback loops”. Presumably, the end result of this effort is that the LX480 won’t just sound like a 480L - it will behave like one too.Īll of which sounds rather enticing already, but Relab’s quest for accuracy didn’t end there: as well as the actual reverb generation, those clever Danes also saw fit to model the analogue side of things. Of the modelling process, Relab’s Martin Lind has commented that, while they didn’t have access to the raw algorithms used in the real thing, their experience in studying digital reverbs means they have “developed methods to determine the exact structures” employed by the original - which bodes well for the emulation! He goes on to say, however, that recreating the algorithm isn’t even the hardest part of the process: mapping the user controls (which are styled to closely resemble a Lexicon LARC) to the algorithm parameters is apparently much more time-consuming. The LX480 is, as its name implies, a model of the revered Lexicon 480L, one of the most iconic digital reverbs ever, and one that still gets used today despite being over 20 years old!

Now Relab have released the first plug-in under their own name, and it promises to be something rather special. They were founded in 2004 and, while you may not have heard their name before, you’ll almost certainly have heard (or heard of) the fruits of their labours: IK Multimedia’s Classik Studio Reverb and SSL’s X-Verb (for their Duende DSP processors) are but two of the plug-ins they’ve had a hand in. Relab Development are a Danish company that specialise in plug-in coding.
