MX300
Stereo Reverb/Effects Processor with USB "Hardware Plug-In" Capability
Our revolutionary MX200 and MX400 changed everything. The great sound of a hardware Lexicon reverb — plus the ability to put that power to work as part of your DAW workflow via PC VST® and Mac® AU plug-ins (32-bit only). Now we’ve packed a significant portion of the MX400’s feature set into the ultra-affordable MX300.

FEATURES
What the MX300 brings.
Our revolutionary MX200 and MX400 changed everything. The great sound of a hardware Lexicon reverb — plus the ability to put that power to work as part of your DAW workflow via PC VST® and Mac® AU plug-ins (32-bit only). Now we’ve packed a significant portion of the MX400’s feature set into the ultra-affordable MX300.
All parameters of every reverb, delay and dynamic effect in this powerhouse processor are available inside any PC VST® or Macintosh® AU compatible DAW program. Just link your computer to the MX300 with a USB cable and control automation and recall parameters exactly as you would with any software plug-in. You get the sonic benefits only Lexicon hardware can provide…without bogging down your computer’s CPU with the extreme demands of reverb plug-ins.
