Octave Shift; Midi Channel - M-Audio Keystation 49es User Manual

Octave Shift

Another method of shifting the Keystation 49es octaves is with the use of the keys labeled "Octave +" and "Octave -
". After the Advanced Function button has been pressed, placing the keyboard in Edit Mode, pressing these keys
will shift the keyboard's pitch up or down one or more octaves (one for each time pressed). The default octave shift
designation is "0" and will be the octave setting each time you power up the keyboard. The lights above the octave
buttons indicate that 0 octave shift is set when both are on.
To assign the "+" and "-" keys to control the octave:
1. Press the Advanced Functions button to get the keyboard into Edit Mode.
2. Press the black key representing "OCTAVE". Edit Mode will finish as soon as OCTAVE has been pressed.
There is also a method of performing a quick octave change, which can be useful when using the octave buttons to
control another MIDI function. This is accomplished as follows:
1. Press the Advanced Functions button to put the keyboard in Edit Mode.
2. Press the black key representing "OCTAVE +", increasing the octave by 1 (you may press it again to
increase the octave by 2, and so on). Press the black key representing "OCTAVE -", decreasing the octave
by 1 (you may press it again to decrease the octave by 2, and so on). Press the black key representing
"OCTAVE 0" to reset the octave shift to 0.
3. When you have chosen your octave shift press "ENTER," to select your Octave and leave Edit Mode.
Selecting Cancel or Advanced will cancel the selection, and exit from Advanced mode.
Transposition
In some cases it may be useful to reduce or increase the pitch by a number of semitones rather than an entire
octave. For example, if you are playing a song with a singer that is having difficulty hitting the top notes, you may
want to reduce the pitch by one or two semitones. This is achieved using a MIDI function called "Transpose."
Transpose works in the same way as Octave Shift above, except the shift can be up +/- 12 semitones. As with
Octave Shift, there are two ways of transposing the keyboard. You can use the Octave "+" and "-" buttons, or the
black keys "TRANSPOSE -," "TRANSPOSE 0" and "TRANSPOSE +," respectively.
To assign the Octave "+" and "-" buttons to transpose:
1. Press the Advanced Functions button to engage Edit Mode.
2. Press the black key representing "TRANSPOSE." (Edit Mode will disengage as soon as "TRANSPOSE" has
been pressed.)
3. Press the "+" key and you will hear the pitch of the note you play go up.
4. Press both "+" and "-" together to cancel transpose.

MIDI Channel

MIDI data from the keyboard can be sent on any of 16 MIDI Channels. However, certain MIDI devices and MIDI
software applications require the keyboard to send data on a specified channel. If this is the case, you can change
the channel the data is sent using the following method:
1. Press the Advanced Functions button to engage Edit Mode.
2. Press one of the 16 Channel keys, according to the Channel that you need.
For example, if a device specifies that you need to send data on Channel 10, press the Advanced Functions button,
and select Channel 10. The Channel can also be assigned to the Octave "+" and "-" buttons. Once assigned,
pressing "+" or "-" will increase or decrease the channel incrementally.
When Channel 16 is reached and "+" is pressed, Channel 1 will be selected. If the Octave "+" and "-" keys are
selected to vary the Channel, the LEDs above the buttons will not change, since it is not possible to have a Channel
with a negative value. Pressing both the "+" and "-" buttons together will recall Channel 1.
