case, is a good idea to try reducing 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 is +/- 12.
As with Octave Shift, there are two ways of transposing the keyboard. You can use
the Octave "+" and "-" buttons, or the black keys F# 3, G# 3 and Bb3. These black
keys represent "TRANSPOSE -," "TRANSPOSE 0" and "TRANSPOSE +," respectively.
To assign the octave "+" and "-" buttons to transpose:
Press the Advanced Functions button to get the keyboard into Edit Mode.
Press the black key above D1 (named D# 1), representing "DATA = TRANSPOSE."
Edit Mode will finish as soon as D# 1 has been pressed.
Press the "+" key and you will hear the pitch of the note you play go up.
*A semitone represents the change in pitch from one note to another. So,
changing two semi- tones is the same as playing a note two notes higher.
Channel
MIDI data from the keyboard can be sent on any of 16 MIDI channels. However,
certain MIDI devices and MIDI software requires 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:
Press the Advanced Functions button to get the keyboard into Edit Mode.
Press one of the 16 channel keys from D1 to E3, whichever one represents
the channel you need.
For example, if a device specifies that you need to send data on Channel 10,
press the Advanced Functions button, and then key F2 to select Channel 10.
The Channel can also be assigned to the Octave "+" and "-" buttons. This will
increment through the channels. 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 lights 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.
Program Change
Program Changes are used to change the instrument or voice you are using.
For example, let's change the instrument to a bass sound. To do this we need
to send a program change of 32, which will select an acoustic bass sound
10
