The latest 008 / 008R OS version is 1.03-00 (released 2nd May 2019).
Updates are downloaded and installed by connecting an Ethernet cable from your local network router to your synth and selecting Update on the Settings->Update page.
If you are experiencing any problems with your 008 / 008R we first recommend that you update your synth to the latest OS version as this may be the solution to the issues.
