Question it is unclear to me if the plug in works with the original (black) System 6000 as well,  or only System 6000 MKII.  Answer You can use the System 6000 Integrator plug-in with any System 6000 MKII mainframe, including the previous-generation Mastering 6000 MKII and Reverb 6000 MKII. The original System 6000 (black) is not supported, but you can of course upgrade your System 6000 frame to MKII specifications
