I will have to figure out how to do a factory reset?
Here is how to do it. But make sure to save what you have now in case you need to get it back.
Here’s a quick trick to revert all sounds and combis of your 01/W(fd) to the factory sounds.
Beware that anything you have entered or changed in the 01/W will be lost!
1. Press both the COMPARE and RESET buttons, keep them depressed and power on the 01/W
2. After a few seconds, the display will show the ROM version and date. All sounds are initialized to one setting.
3. Press the GLOBAL button, and go with the PAGE+ button to page 7.
4. Press the LOAD soft-key and answer with YES.
5. Now your 01/W contains the factory sounds and presets.
