Q: Why are the keys on my keyboard playing the wrong notes (e.g. The C key triggers a C# note)?

A: M-Audio keyboards allow you to transpose the keyboard which lets you change the pitch you are controlling and continue to play in the key that is most comfortable for you.  It is possible to transpose up or down by as much as 12 MIDI notes (or semitones).

Axiom Series: To transpose the pitch you are playing, locate the Octave / Transpose buttons and press them both together.  The current transpose value will show on the LCD display.  Press either > to transpose up by one half step, or < to transpose down by one half step.  The transpose value on the LCD will update accordingly.  When you stop pressing the Octave / Transpose buttons, the “Trans” symbol on the LCD display will stop flashing and performance mode will resume.

Axiom Pro: To transpose the pitch you are playing, locate the Octave / Data buttons and press them both together.  The current transpose value will show on the LCD display.  Press either > to transpose up by one half step, or < to transpose down by one half step.  The transpose value on the LCD will update accordingly.  When you stop pressing the Octave / Data buttons, the display will result to its default state and performance mode will resume.

Oxygen Series: To activate the Transpose function, press both Octave up and down buttons simultaneously and then use the up and down buttons to adjust transposition by one semitone.  Press Octave up one time for each semi tone you want to transpose up, and press Octave down one time for each semi tone you want to transpose down.

Keystation Pro 88: To activate the Transpose function, press both Octave + and - buttons simultaneously and then use the + and - buttons to adjust transposition by one semitone.  Press Octave + one time for each semi tone you want to transpose up, and press Octave - one time for each semi tone you want to transpose down.

O2/KeyStudio 25/KeyRig 25: To activate the Transpose function, press both Octave up and down buttons simultaneously and then use the up and down buttons to adjust transposition by one semitone.  Press Octave up one time for each semi tone you want to transpose up, and press Octave down one time for each semi tone you want to transpose down.
