Octave Shift
Another method of shifting the Q88 MKII octaves is with the use of the keys labeled "Octave
+" and "Octave -". After the Advanced 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 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 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, except the shift can be up to +/- 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 button to engage Edit Mode.
2. Press the black key labeled "TRANSPOSE" (Eb2). (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 the "-" key to transpose the keyboard down a half-step.
5. Press both "+" and "-" together to return to no transposition change.
