I really should read documentation a little more carefully rather than skimming.
My recent synth OS upgrade contained TWO OS files. One for models containing the KORE 64 DIMM installed, and one for those without. For some strange inexplicable reason, I thought my particular model HAD it installed but upon opening up the back panel to reseat the DIMM, I found it wasn't there and never had been.
A quick hard reset to delete the proprietary objects and a reinstall of the proper OS file fixed the issue, but NOW I want the KORE 64 upgrade. It's got tons more sounds of all types from orchestral to vintage synths, guitars, basses and drum kits.
Eh, you live and learn and fortunately didn't do any damage to my baby.
Time for a relaxing mug o' tea.
Still time for people to buy my CD hard copy, or via iTunes and similar if you wanna go with a digital version. You don't get the nice informative insert that way though.
