Modulation Control
The Modulation control is used for modulation of the sound being played. This type of real-time controller was introduced on electronic
keyboards to give the performer the option of adding vibrato to similar to acoustic instruments.
The Modulation control on your M-Audio O keyboard is fully MIDI assignable. Please refer to the "Programming and Editing" section of this

Foot Switch
Any polarity foot switch (not included) can be plugged in to the foot switch input on your M-Audio O keyboard. The keyboard will automatically
2
detect the correct polarity upon powering on. If you want to reverse the polarity, make sure the pedal is pressed when you switch on your
keyboard.
The foot switch is normally used for sustaining the sound you are playing without having to keep your hands on the keyboard. This is also the
default function on your M-Audio O keyboard.

On the M-Audio O , you can program the footswitch to send out MIDI notes that can trigger samples on different MIDI channels, without
2
moving your hands from the keyboard. You can also send Program Changes any other MIDI message that can be sent from the 8 assignable
MIDI buttons on your keyboard.
For more detail about how to program the foot switch, please read the "Programming and Editing" section of this manual.
MIDI Out
On the back of the keyboard is the MIDI output port that can connect to an external sound module or MIDI keyboard. By default, all controller
data is sent out via the MIDI output as well as the USB out.
To have the MIDI output function like a USB-to-MIDI interface, engage "MIDI Out from USB" Mode by pressing the ADVANCED FUNCTION
button and then the key on the keyboard labeled MIDI OUT.
For more information on "MIDI Out from USB" Mode, please read the "Programming and Editing" section of this manual.

Introduction to Programming Options
Each of the M-Audio O 's controllers can send MIDI CC, RPN/NRPN, GM 1&2, and SysEx messages. They can also be assigned to individual
2
MIDI channels.
MIDI CC (continuous controller) numbers are part of the standard MIDI specifications and are typically used to control the real-time changing
of parameters in musical equipment. For a complete list of standard MIDI controller numbers from 0 to 131, please see Appendix E.
Any of the real-time controllers on the keyboard can be assigned to a MIDI CC number; the 8 assignable buttons and pedal have slightly
different options from the Fader or rotary controllers.
The 2 charts show the transmit messages that can be programmed for each of the 8 knobs, the fader, and assignable MIDI buttons.
Please pay extra attention to the differences between programming the faders or knobs and programming the buttons.
