Advanced Functions
In addition to setting an octave shift, the two octave "+" and "-" buttons discussed earlier in the manual under
the section "Octave Buttons" can also be used to control one of six MIDI functions.
The first 6 black keys are used to select the function of the octave buttons. Some of the functions that these
keys can be used for cannot send out a value less than 0. When used to control these functions, both LEDs
above the buttons will remain on, regardless of the current setting of that function.
To select an alternate function:
1. Press the Advanced Functions button, putting the keyboard into Edit Mode.
2. Press the black key that represents the function you want. Edit Mode will finish as soon as you have
selected the function and you will be able to play notes again.
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.
