User manual M-AUDIO OXYGEN 25

[. . . ] M-AUDIO Oxygen Series User Guide Oxygen Series User Guide 2 1 Introduction Congratulations on purchasing an M-Audio Oxygen Series keyboard. Oxygen keyboards now offer DirectLink, which provides support for Digital Audio Workstations (DAW)1 such as Pro Tools 8 by automatically mapping the track and master volume sliders, slider buttons, pan knobs and transport controls to their corresponding functions in the program. A single USB connection not only sends MIDI data to the computer, but also provides power to the keyboard. All Oxygen Series keyboards function as class-compliant devices and will be recognized by your computer without the need to install additional drivers. [. . . ] Generally, this is achieved by selecting the control for editing and assigning a 3-digit number. This section provides examples of the typical control assignment procedure for knobs, sliders, buttons and the sustain pedal jack. Assigning MIDI messages that are not explicitly mentioned in this section is done by using the same basic principle as given in the examples. Appendix A lists the standard MIDI CC numbers from 0 to 127 and their corresponding General MIDI parameters. Appendix B lists the additional, M-Audio specific MIDI assignment options (128 - 255), grouped by control type (sliders & knobs / buttons & sustain pedal jack), as well as their corresponding data type and purpose. NOTE: Your Oxygen keyboard never transmits values outside the range specified by the MIDI protocol (0-127). The controller numbers from 128 - 255 are only used internally by your Oxygen keyboard. This simplifies configuration of the knobs, buttons and sliders when assigning advanced MIDI messages, and allows additional configuration options for the controls (for example, setting Trigger or Toggle operation of a button). Oxygen Series User Guide 4 Setting Toggle Values (Min/Max) for Buttons or the Sustain Pedal When standard MIDI CC numbers are assigned to buttons or the Sustain pedal, they will toggle between two values. This means that one value is sent the first time it is pressed, and another value is sent the next time it is pressed. By default, the buttons on your Oxygen Series keyboard are already configured to operate as toggle switches. When configuring a button or the sustain pedal to operate in toggle mode, the following three values need to be specified: Key Control Assign (example) Data 2 (example) Data 3 (example) Parameter MIDI CC number Second press First press 10 (Pan) 0 (minimum) 127 (maximum) Value The following example will configure a button to "hard pan" the sound to the left speaker when it is pressed the first time, and "hard pan" to the right speaker when it is pressed a second time: 1. Select a button as described earlier in this guide Press the Advanced button Press the Control Assign key Type 10 using the number keys. This assigns MIDI CC number 10 (Pan) to the button. See Appendix A Press the Enter key Press the Advanced button Press the Data 2 key Type 0 using the number keys to assign the "second button press" (minimum) value Press the Enter key Press the Advanced button Press the Data 3 key Type 127 using the number keys to assign the "first button press" (maximum) value Press the Enter key TIP: It can be useful to transmit two other specific values instead of sending minimum (zero) and maximum (127) values as in the above example. When assigning a button to control Pan (MIDI CC 10), you can, for example, configure Data 2 to send value 38, and Data 3 to send value 93, effectively causing pan to switch between the approximate "ten o'clock" and "two o'clock" positions when pressing the button repeatedly. NOTE: If you want the button to send the same value every time it is pressed, enter the same value for both the Data 2 and Data 3 parameters. Oxygen Series User Guide 5 Setting Trigger Values for the Buttons or the Sustain Pedal It is possible to set a Trigger Value for a button or the sustain pedal, causing it to send one value when pressed and held down, and another value when released. The sustain pedal is already configured to send trigger values by default, ensuring it activates the sustain effect when pressed and deactivates it when the pedal is released. Buttons can also be configured to operate this way, which requires four values to be specified. At the example of the sustain pedal, these four values are: Key Control Assign Data 1 (example) Data 2 (example) Data 3 (example) Parameter Trigger On/Off operation MIDI CC number Button/Pedal Released Button/Pedal Pressed 146 64 (Sustain) 0 (minimum) 127 (maximum) Value NOTE: When working with proprietary M-Audio parameters from the 128-255 range, the "Control Assign" setting is used to configure a button or the sustain pedal for this special mode of operation. This means that certain values that are usually specified through the "Control Assign" setting must instead be specified via the "Data 1" parameter (such as the standard MIDI CC parameter in the example below). The following example will configure a button to "hard pan" the sound to the right speaker when it is held down, and "hard pan" to the left speaker when it is released. This involves configuring the button to operate as a trigger, while controlling the Pan parameter (MIDI CC 10): 1. Select a button as described earlier in this guide Press the Advanced button Press the Control Assign key Type 146 using the number keys. [. . . ] This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Re-orient or relocate the receiving antenna. Increase the separation between the equipment and receiver. [. . . ]
