Transpose
In some cases it is useful to increase or decrease the transmitted pitch by a small number of semitones rather than a whole octave.
For example, you may be playing a song with a singer and the singer is having trouble hitting the high notes. In this case, you can try
reducing the pitch by one or more semitones. This is achieved using a function called "Transpose."
Transpose works similar to octave shift, except the shift is not limited to multiples of 12 semi-tones. As with octave shift, there are
two ways of transposing the keyboard. When in Edit mode, you can assign the Octave "<" and ">" buttons to control the transpose
feature. Alternatively, you can use the black keys F#3, G#3, and Bb3 to shift the transposition. These black keys represent
"TRANSPOSE -," "TRANSPOSE 0" and "TRANSPOSE +" respectively.
To assign the Octave "<" and ">" buttons to transpose:
1. Press the Edit Mode button.
2. Press the black key above D1 (D#1), representing "DATA = TRANSPOSE." KeyStudio will exit Edit mode as soon as D#1
has been pressed.
When the Octave buttons are assigned to transpose the keyboard, the lights above the buttons indicate the direction of the
transposition. To return the keyboard's transpose shift to zero, press both the Octave "<" and ">" buttons at the same time.
Channel
MIDI data from the keyboard can be sent on any of 16 MIDI channels. KeyStudio's default is to transmit MIDI data on channel 1.
However, certain MIDI performance or recording scenarios may require the keyboard to send data on a different channel. You can
change the channel on which data is sent using the following method:
1. Press the Edit Mode button.
2. Press one of the 16 channel keys from D1 to E3, whichever one represents the channel you need. KeyStudio will exit Edit
mode as soon as a channel key has been pressed.
For example, if a device specifies that you need to send data on channel 10, press the Edit Mode button, and then F2 to select
channel 10. This channel is usually dedicated to drum sounds when working with GM compatible synthesizers and sound modules.
The channel can also be assigned to the Octave "<" and ">" buttons by pressing the Edit Mode button and then C#2. This will allow
the Octave "<" and ">" buttons to increment or decrement through the channels. When channel 16 is reached and ">" is pressed,
channel 1 will be selected. If the Octave "<" and ">" keys are assigned 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
KeyStudio's default, channel 1.
