709         * just of historical nature, because the gig format was derived from the

712         * Each Region consists of at least one or more DimensionRegions. The actual
713         * amount of DimensionRegions depends on which kind of "dimensions" are

1003         *
1004         * Groups help to organize a huge collection of Gigasampler objects.
1005         * Groups are not concerned at all for the synthesis, but they help
1006         * sound library developers when working on complex instruments with an
1007         * instrument editor (as long as that instrument editor supports it ;-).
1008         *
1009         * At the moment, it seems as only samples can be grouped together in
1010         * the Gigasampler format yet. If this is false in the meantime, please
1011         * tell us !
1012         *
1013         * A sample is always assigned to exactly one Group. This also means
1014         * there is always at least one Group in a .gig file, no matter if you
1015         * created one yet or not.
