SysEx Messages and Device ID
When transmitting SysEx messages, the individual control channel number does not define a transmit channel, but a
Device ID. When the CHAN ASGN key is pressed, the "c" is not displayed on the LED screen.
Device IDs range between 0-127. In most cases, the Device ID should be set to 127 so that all devices will receive the
SysEx message.
The Device ID for a SysEx message assigned to a controller cannot be changed using the Device ID key. This key is
used for varying the global Device ID of Oxygen 88.
Non-Volatile Memory
All Oxygen keyboards feature non-volatile memory, which allows for automatic saving of preset patches when the
device is powering down. The current controller and channel assignments are stored even if the Save function has not
been used. The Program, Bank LSB and Bank MSB data, Global Channel setting, and last used memory preset patch
are also stored.
Restoring the Factory Settings
Factory default settings can be restored by holding down the - and + buttons during power-up. At this point all
previously saved data will be erased.
