Elektron Octatrack MKII

Two upgrade methods. .BIN via USB+CF card (preferred): on the Octatrack, navigate to SYSTEM → USB DISK MODE and press [ENTER/YES]; copy the .bin OS file to the root of the Compact Flash card; unmount, then navigate to SYSTEM → OS UPGRADE and press [ENTER/YES]. SYSEX via MIDI (alternative): connect the Octatrack MIDI IN to a computer MIDI interface (the USB port cannot transmit the OS); send the .syx file using Elektron Transfer or any sysex-capable tool. Do not power off the unit during the final bootstrap stage.
