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 ID’s 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 an Oxygen Series keyboard.

For more information, please refer to the SysEx Messages and Device ID sections.

Non-Volatile Memory

All Oxygen keyboards feature non-volatile memory, which allows for automatic saving of presets 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 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.
