To restore the operating system of a Supernova or Supernova II, hold
down part edit button 6 while you turn the synthesiser on. The display
will show "reload O/S from ROM to flash?". Push the page up button to
accept this prompt. The reload should take around 5 seconds.
Once the reload is complete you can restore the factory settings for
the Supernova or Supernova II. To do this find the local control &
memory protect page in the global menu. Ensure that local control is
turned on and memory protect is turned off. Press the page up button to
advance to the restore from ROM page of the global menu. Use the fast
data controls to select "total data" as the option to be restored.
Push the write button twice to initiate the reload. This reload takes
around 15 seconds. Once the reload has taken place, the memory (not the
buffers) will have been initialised. Turn the Supernova off and back on
again or advance to a new Program / Performance to clear the buffers.
The items that are restored are: Program banks A-D, Performance banks
A-B, Drum Banks a-d (Supernova II only), all arp patterns and the
global menu data. Program banks E-H, Performance banks C-D, Drum Banks
e-h cannot be restored as these are not stored in ROM.
