2.8 The Instrument Buttons
The instrument buttons can also be used to send Program changes out on the current transmit channel of your ProKeys 88sx. The Program changes
that these buttons send are listed in the table below. The Program change message will be accompanied by a Bank LSB and MSB message with a
value of zero. These are also the Program messages you will need to send from your computer or sequencer to the ProKeys 88sx, in order to play
the programs from an external source.

2.9 Transpose Buttons
The Transpose buttons can be used to change the pitch of the instrument. Some players like to play in a particular key like C or F, for example.
Transpose lets you change the pitch of your instrument 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 semitones. This means if you press the Transpose + or – button 12 times, the tone will sound exactly one octave higher
or lower.
The Transpose buttons each have an associated LED. When the ProKeys 88sx is not transposed, both LEDs will be off. If you set the transpose to a
negative value, the LED above the Transpose - button will light up, but the LED above the Transpose + button will remain off. If you set the transpose
to a positive value, the + LED will light up.
Pressing both Transpose buttons at the same time will set the transpose back to zero, and both LEDs will switch off.
Note: If you have assigned the Transpose buttons to a function other than transpose, it is still possible to transpose your ProKeys 88sx, using the
Transpose + and Transpose – function keys in Edit mode:
< Press Advanced Functions.
< Press key C#4 to decrease the pitch, or D#4 to increase it.
2.9.1 Octave
It is also possible to set the Transpose buttons so as to shift a whole octave “on the fly.” This is achieved as follows:
< Press Advanced Functions.
< Press key C#1.
It is possible to change the keyboard’s pitch by a maximum of one octave down or two octaves up. Pressing both Transpose buttons together will
set the octave shift back to zero and both LEDs will turn off.
In order to switch the Transpose buttons back to controlling Transpose:
< Press Advanced Functions.
< Press key D#1.
If you just want to make a quick octave adjustment, and do not wish to alter the assignment of your Transpose buttons, this is achieved using the
Octave + and Octave – function keys when in Edit mode.
< Press Advanced Functions.
< Press key C#3 to decrease the pitch, or D#3 to increase it.
