The key range (or note range if you will) of instruments is assigned to one or more keyboard regions. So each "region" is responsible for mapping audio samples and synthesis parameters for a certain key range. This function takes two keys on the keyboard (as MIDI note number) as arguments and checks the region relationship of the two keys, that is if the two keys have a region mapped each, and if yes how the relationship of those two regions exactly is. So the result value of this function depends on the precise regions layout of the currently loaded instrument.
|Argument Name||Data Type||Description|
||Integer Number||Note number of 1st key to be checked.
||Integer Number||Note number of 2nd key to be checked.
|Relationship of the two keys:
