same_region()

The key range (or note range if you will) of instruments is assigned to one more multiple 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 numbers) 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.

??key1?? Integer Number Note number.
[required]
??key2?? Integer Number Note number.

Return Value

Description Data Type
Relationship of the two keys:
0: Both keys have a region, however they are two different regions, which also and don't overlap each other.
1: Both keys have a region and it is exactly the same region.
2: Both keys have a region, which are two different regions, they are overlapping each other though.
3: ??key1?? has a region, ??key2?? does not have any region.
4: ??key1?? does not have any region, ??key2?? has a region.
5: ??key1?? and ??key2?? both don't have any region.
Integer Number
The GigaStudio/Gigasampler format currently does not officially allow overlapping regions. So the designated return value 2 is reserved for such a potential future feature.
