SOLD: Lexicon MX400 Dual Stereo / Surround, Reverb, Delay, & Modulation FX Processor. This is quite a powerful 1u rack mount effects processor from the 2010s. It has some unique features from the era, including a VST/AU (32-bit only) app and a standalone MX Edit app that can control the unit via USB. Since the unit has midi and USB, you can use the standalone app via USB and use standard midi to automate parameters in your DAW. If your DAW still supports 32 bit plugins, you can just use the VST.

Depending on configuration / how many effects you're using, it also has some very nice EQ/ducking features on some of the reverbs and delays. If you're using all 4 FX channels, you can't get to these features (bummer, but that's how it's setup). If you're using 2 FX channels (1 FX per stereo pair, which is how we used it in the studio), you then get access to the unique EQ/ducking parameters, which are ideal for getting a good, modern, clean sound.

Sale includes unit, power cord, and USB cord. Overall condition is nice and clean, though the black chassis is not without imperfections. It works flawlessly and has been well taken care of.
