The operating system of the SP-808/SP-808EX can be updated by using MIDI files supplied by Roland. Use the following procedure to update the operating system via MIDI:
1. Connect the MIDI OUT of a MIDI sequencer (computer-based, MC-50MKII, etc.) to the MIDI IN of the SP-808/SP-808EX.
2. Load the first MIDI file of the update into the sequencer.
3. Hold down the STATUS & EFFECTS buttons for Track A and then power on the SP-808/SP-808EX to display "MIDI UPDATE - Waiting MIDI . . ."
4. Send the first MIDI file from the sequencer.
5. Repeat step #4 for the remainder of the MIDI files.
6. When all the files have been sent, turn off the SP-808/SP808EX and turn it back on.
