The number of memories that can be saved on the OD-200 depends on the version of the system program. To check the current version on your OD-200, insert a plug into the INPUT A jack while holding down the [MEMORY] button. The device will power on, and the version will be displayed on the display.
- Older versions than Ver.1.10: 4 + Manual

Version 1.10 and later: 127 + Manual
The ETF (EXTENT FROM) and ETT (EXTENT TO) parameters allow you to change the range of memories that are switched by pressing the MEMORY button. For instructions on how to set this, please refer to the "Overall Settings (Menu)" section of the OD-200 Owner’s Manual.
