How to update the Sequentix Cirklon2

1. Back up your data first: save everything as a single SYX file. 2. Download the OS ZIP for your model from the Sequentix downloads page and copy CK2OS.SYX to the root of the SD card. Cirklon and Cirklon2 use different OS files: use the one marked Cirklon 2. 3. Insert the SD card and hold step key 1 while powering on to enter firmware update mode. 4. Press encoder 8 to install the update. The OS can also be sent over MIDI as SysEx (slower). A failed update cannot brick the unit: just repeat it.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
