The KEYHOLD and MOD LEDs light and the Scatter wheel LEDs flash. The OCTAVE UP and DOWN LEDs flash one after the other when the PC is connected to the SYSTEM-1
3. The drive that appears in the PC now contains two folders, BACKUP and RESTORE. The BACKUP folder contains 64 files, named SYSTEM1_PATCH1 thru’ SYSTEM1_PATCH64. To backup these files, copy them to another drive/folder on the PC.
NOTE: If a PLUG-OUT synth is loaded, such as the SH-101, there will be additional files in the backup directory. These will be named PLUGOUT_PATCH1 thru’ PLUGOUT_PATCH64.
4. To restore any backed up patches, copy the required files from the PC to the RESTORE folder on the SYSTEM-1 drive. Note that the files you copy must follow the same naming format as shown above. In addition, note also that any patches copied to the RESTORE directory will overwrite whatever is currently stored in the SYSTEM-1.
5. Wait until the OCTAVE UP and DOWN LEDs stop flashing then restart the SYSTEM-1.
