PROGRAMMING BASICS
KEY NUMBER
The Key Number is affected by the Keyboard Center parameter which
can be set to any key from A-2 to G8. 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 velocity curves in
order to match your playing style or better adapt to the MIDI
controller. Experiment with the curves to find the one that works best
for your style and MIDI controller.
