Watch the display as you turn it on. The software release number is
displayed under “KARMA Music Workstation” at the bottom of the
screen, next to KORG.
OS Software releases are available from Korg USA, Korg Germany, Korg
Japan, and other distributors on their web sites. There are also complete
instructions on how to install it, in the applicable language. There are
direct links on my site at: www.karma-lab.com -> [Specs, Manuals & Updates]
