/** @brief Group of Gigasampler objects |
650 |
|
* |
651 |
|
* Groups help to organize a huge collection of Gigasampler objects. |
652 |
|
* Groups are not concerned at all for the synthesis, but they help |
653 |
|
* sound library developers when working on complex instruments with an |
654 |
|
* instrument editor (as long as that instrument editor supports it ;-). |
655 |
|
* |
656 |
|
* At the moment, it seems as only samples can be grouped together in |
657 |
|
* the Gigasampler format yet. If this is false in the meantime, please |
658 |
|
* tell us ! |
659 |
|
* |
660 |
|
* A sample is always assigned to exactly one Group. This also means |
661 |
|
* there is always at least one Group in a .gig file, no matter if you |
662 |
|
* created one yet or not. |
