11 Troubleshooting
Oxygen keyboard suddenly stops working.
Turn off the unit for 10 seconds, then restart your computer and power up the keyboard. If the problem persists,
check the M-Audio website for the latest drivers and re-install them.
The keyboard is connected to my computer with the USB cable, but I cannot locate my Oxygen
keyboard in my software’s MIDI devices dialog box.
Your Oxygen keyboard may not be receiving enough USB bus power to function correctly. Try plugging it into a
different USB port or a powered USB hub connected to your computer.
In Windows XP, the Oxygen MIDI ports will appear as "USB Audio Device" if the optional drivers have not
been
installed. Select "USB Audio Device" as your audio and MIDI input and output device.
Please refer to Chapter 5 of this guide for instructions on how to install the Oxygen Series Drivers.
The Oxygen keyboard does not trigger sounds in my music software.
Most programs have a MIDI activity indicator that can be used to confirm whether MIDI data from the keyboard
is reaching the software. If the software is not receiving any MIDI data, be sure the controller is properly
installed and is selected as a MIDI input device within your software. Refer to the documentation for your DAW
software, to learn how to configure and select MIDI input devices.
If the MIDI activity display indicates that MIDI data is reaching your software, then you may not be hearing
sounds because the MIDI data is not being routed correctly through the software itself. Refer to the
documentation for your DAW software, to learn how to route MIDI data properly.
When playing a virtual instrument loaded in my music software, there is a noticeable delay before I
hear any sound.
This delay is known as latency, and it may be possible to reduce it through the Control Panel of your audio
interface. Please refer to your audio interface’s User Guide to see if this is possible.
I have connected a sustain pedal to my Oxygen keyboard, but its operation is reversed (i.e., the notes
sustain when the pedal isn’t pressed, but the notes stop sustaining once the pedal is pressed).
The polarity of the sustain pedal is determined by the keyboard upon startup. When the keyboard is powering
up, the sustain pedal is assumed to be in the "up" (off) position. It is important that the sustain pedal is not
pressed down during startup, otherwise its operation may be reversed.
My virtual instrument software (or hardware MIDI module) always recalls the sound next to the
program change number that I have sent to it from my Oxygen keyboard. For example, if I send a
program change number 40 (Violin), my MIDI module or software loads sound number 41 (Viola).
This behavior is normal. Some MIDI devices count their sound presets from 1-128 instead of 0-127. As a
result, there may be an offset of +/-1 between the program change number sent from the keyboard and the
recalled sound preset on your module.
I have changed many parameters and would like to go back to the keyboard’s default settings.
Oxygen Series keyboards can be reset to their "factory" settings by simultaneously pressing the "+" and "
-"
buttons as the unit is switched on.
