6. Function Buttons:

All Oxygen Series keyboards feature 5 function buttons for programming, access to settings and advanced features as outlined below.

Advanced

The Advanced button allows access to the extended parameters listed along the top edge of the keyboard. When the Advanced button is pressed, the LED screen shows three dots along the bottom of the display, indicating that the keyboard is in Advanced mode. Please refer to Section 8 - Advanced Keyboard Functions and Section 9 - Advanced Programming Functions for more information on how this function is used.

Mute

When the Mute button is activated, the Knobs and Sliders will not transmit MIDI data and the LED screen will display "OFF" while adjusting them. This allows changes to Slider and Knob positions without affecting the settings of connected MIDI devices or applications.

As shown in the following example, the Mute function can be used to prevent "jumps" caused by differences between the physical positions of sliders and knobs on an Oxygen keyboard, and the expected values of the corresponding software parameters:

When loading a new sound patch for a virtual instrument in your DAW software, its settings will likely not match the current positions of the knobs on the Oxygen keyboard and will be "out-of-sync" with what the virtual instrument is expecting. In other words, an Oxygen Knob may be set to 64 (center position) while the sound patch expects this value to be at zero (all the way to the left). This may cause this synthesizer setting to jump or "snap" from zero to 64 when the Oxygen Knob is adjusted, which can be a jarring experience if the knob is controlling a parameter like Master Volume or Filter.

These value jumps can be prevented by first pressing the Mute button, and then setting the Knobs and Sliders to their expected positions before using them with a new sound patch. Press the Mute button a second time to exit Mute mode.

NOTE: The Mute function does not affect the buttons, keys or the sustain pedal and pressing any of them automatically cancels Mute mode.

Snapshot (Advanced & Mute)

Pressing the Advanced and Mute buttons at the same time activates the Snapshot function. The LED screen momentarily shows "S-S" and the Oxygen keyboard immediately sends the current values of all knobs and sliders. This feature can be used to simultaneously change multiple parameters within the software you are controlling to match the settings on your Oxygen keyboard.

Select

The Select button assigns the "-" and "+" buttons to one of three parameters as indicated by a dot along the lower edge of the LED display:

GLOBAL; The - / + buttons set the global MIDI channel.

PGM (program); The - / + buttons transmit program change messages.

PRESETS; The - / + buttons step through and load Oxygen presets from its 10 memory locations.

"-"and "+" Buttons

These buttons are used in combination with the Select button, to decrease (-) or increase (+) the value of the currently active function or parameter (Global MIDI channel, Program Change, Preset Number).
