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 seven MIDI
functions.
The first 7 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 button, putting the keyboard into Edit Mode.
2. Press the black key that represents the function you want. With the exception of CC,
Edit Mode will finish as soon as you have selected the function and you will be able to
play notes again.
