Hi All, I've recently become the proud owner of an MB-6582 :frantics: so now have access to 4 cores rather than the 1 core of my little Sammich. I set up a multi patch (patch 1) on the first core and used up the 6 voices (on MIDI channels 1-6). Then I set up a core 2 multi patch (patch 2) where I had set the MIDI channels to 7-12 in the Ensemble. The problem I am having is that when I want to edit the voices in core 2 (patch 2) via the sysex editor, it changes the patch 1 settings too.
