The Keyboard - M-Audio AXIOM 25-49-61 User Manual

2.1 The Keyboard

When you play the keyboard, MIDI note messages are sent. These messages are read by your computer software or external MIDI
gear and used to generate sound accordingly.
2.1.1 Velocity Curve
Every time you press a key, a MIDI note message is sent with a velocity value between 0 and 127; this value specifies how hard you
pressed the key. A velocity value of 0 specifies that the key has been released. Since different people have different playing styles,
your Axiom offers a number of different velocity curves. You should experiment with the different velocity curves to find the curve
that best suits your playing style.
It is also possible to send fixed velocities each time you press a key. This is useful when composing drum parts or simple synthesizer
tracks. The fixed velocities are selected by assigning curve 10 to 12 as follows:
To change the velocity curve:
49- and 61-note versions:
Locate the label Vel Curve. Press the two buttons above this label.
<
The LCD will show the currently selected velocity curve, preceded by a 'C' if a curve is selected, or 'F' if a fixed
<
velocity is selected.
Enter the new curve number using the numeric keypad or use the -/+ keys to select a different curve.
<
25-note version:
Press the Advanced button. This sets the keyboard to control data entry.
<
Press the Curve key on the keyboard.
<
The LCD will show the currently selected velocity curve preceded by a 'C' if a curve is selected, or 'F' if a fixed
<
velocity is selected.
Enter the new curve number using the numeric data entry keys or use the -/+ keys to select a different curve..
<
Press the ENTER key to confirm the selected curve.
<
The velocity curve is saved whenever you power down your Axiom.
2.1.2 Octave
There are 128 possible notes that can be sent as MIDI messages. If you wish to play a note that is out of your keyboard's range, it
is possible to shift the keyboard's range up or down using the Octave buttons. The Octave buttons shift the range of the keyboard
up or down by 12 notes at a time. All of the 128 notes can be accessed via the Octave button.
To access all 11 available octaves from your keyboard:
Locate the Octave buttons.
