Matrix-6G VST3


Matrix-6G is a VST3 plugin designed to be used with the Matrix-6R rack-mounted analog synthesizer module, manufactured by Oberheim in the mid-1980s. It presents all of the synthesizer’s patch parameters in a single editor window within your DAW and allows for the automation of parameter changes. It also lets you store and recall patches, as well as edit Splits and Master settings.

At the moment, this plugin is only fully-functional in Cubase from Steinberg (version 10 and later) and Reaper from Cockos (version 6 and later). It is only compatible with 64-bit hosts (Windows OS only). The plugin is optimized for version 2.13 of the Matrix-6R hardware module’s firmware.  It may have limited compatibility with the Matrix-1000 module and the Matrix-6 keyboard model, but I have no way to test this. Similarly, I have no idea if this plugin is compatible with any third-party modification of the module’s firmware (it probably is not).


Simply download the .zip file and extract the .vst3 file into a folder on your computer where you store 64-bit VST3 plugins.

There is a PDF in the download folder that explains how to set up tracks for using the plugin in Reaper and in Cubase. Or you can watch this introductory video:
