Yes, you can There are several options to do this:
Option 1: you can use the “Fac R” (= factory reset) option on the global menu page 3. You need to click 2 times to confirm and it will take 2 minutes to complete. Once the message on the screen is gone, the process is complete.
However, this procedure will also copy the 4 voices preset to preset 2-99. If you don’t want to have these copies in the other presets you can follow the steps in option 2.
You first power off your SSP and you remove the microSD card.
you insert the microSD card (using the adapter) into your computer. In case you receive warnings about formatting the card, please ignore (this might be the case when you are using a windows computer).
You go to the “factory” folder (BOOT partition of the microSD card) and you copy the 2 presets from the “factory” folder to the “presets” folder. Of course, this will overwrite preset 00 and 01 (if you want them at a different preset number, you have to rename them first but make sure you use the same naming convention)
You safely remove/eject the SD card (!) and put it back in the SSP
You power up the SSP again
Let me know if this fixes your problem?
