PROGRAMMING BASICS
KEY NUMBER
The Key Number is affected by the Keyboard Center parameter which
can be set to any key from A-1 to C7. The keyboard center establishes a
reference point for keyboard modulation; keys above this point will have
a positive value, while keys below it will be negative. For example, if we
wished to change the volume of an instrument using key number and the
key center were set to middle C, the instrument would get progressively
louder above middle C and progressively softer below middle C.

VELOCITY CURVES
Incoming velocity values can be scaled by one of the four velocity curves
in order to match your playing style or better adapt to the MIDI controller.
Experiment with the four curves to find the one that works best for your
style and MIDI controller.
