/** @brief Group of Gigasampler objects |
648 |
|
* |
649 |
|
* Groups help to organize a huge collection of Gigasampler objects. |
650 |
|
* Groups are not concerned at all for the synthesis, but they help |
651 |
|
* sound library developers when working on complex instruments with an |
652 |
|
* instrument editor (as long as that instrument editor supports it ;-). |
653 |
|
* |
654 |
|
* At the moment, it seems as only samples can be grouped together in |
655 |
|
* the Gigasampler format yet. If this is false in the meantime, please |
656 |
|
* tell us ! |
