* GIG FORMAT EXTENSION: Added attribute
  DimensionRegion::SustainReleaseTrigger which allows to define whether
  a sustain pedal up event shall cause a release trigger sample to be

451     * format. A DimensionRegion provides the link to the sample to be played
452     * and all required articulation informations to be interpreted for playing
453     * back the sample and processing it appropriately by the sampler software.
454     * Every Region of a Gigasampler Instrument has at least one dimension
455     * region (exactly then when the Region has no dimension defined). Many
456     * Regions though provide more than one DimensionRegion, which reflect
457     * different playing "cases". For example a different sample might be played
458     * if a certain pedal is pressed down, or if the note was triggered with
459     * different velocity.
460 schoenebeck 2 *
461 schoenebeck 2699 * One instance of a DimensionRegion reflects exactly one particular case
462     * while playing an instrument (for instance "note between C3 and E3 was
463     * triggered AND note on velocity was between 20 and 42 AND modulation wheel
464     * controller is between 80 and 127). The DimensionRegion defines what to do
465     * under that one particular case, that is which sample to play back and how
466     * to play that sample back exactly and how to process it. So a
467     * DimensionRegion object is always linked to exactly one sample. It may
468     * however also link to no sample at all, for defining a "silence" case
469     * where nothing shall be played (for example when note on velocity was
470     * below 6).
471 schoenebeck 2 *
472 schoenebeck 2699 * Note that a DimensionRegion object only defines "what to do", but it does
473     * not define "when to do it". To actually resolve which DimensionRegion to
474     * pick under which situation, you need to refer to the DimensionRegions'
475     * parent Region object. The Region object contains the necessary
476     * "Dimension" definitions, which in turn define which DimensionRegion is
477     * associated with which playing case exactly.
478     *
479     * The Gigasampler/GigaStudio format defines 3 Envelope Generators and 3
480     * Low Frequency Oscillators:
481     *
482 schoenebeck 2 * - EG1 and LFO1, both controlling sample amplitude

736 schoenebeck 809 *
737 schoenebeck 2699 * This class provides access to the actual audio sample data of a
738     * Gigasampler/GigaStudio file. Along to the actual sample data, it also
739     * provides access to the sample's meta informations like bit depth,
740     * sample rate, encoding type, but also loop informations. The latter may be
741     * used by instruments for resembling sounds with arbitary note lengths.
742     *
743 schoenebeck 809 * In case you created a new sample with File::AddSample(), you should
744     * first update all attributes with the desired meta informations
745     * (amount of channels, bit depth, sample rate, etc.), then call
746     * Resize() with the desired sample size, followed by File::Save(), this
747     * will create the mandatory RIFF chunk which will hold the sample wave
748     * data and / or resize the file so you will be able to Write() the
749     * sample data directly to disk.
750 schoenebeck 1154 *
751     * @e Caution: for gig synthesis, most looping relevant information are
752     * retrieved from the respective DimensionRegon instead from the Sample
753     * itself. This was made for allowing different loop definitions for the
754     * same sample under different conditions.
755 schoenebeck 2699 *
756     * Since the gig format was designed as extension to the DLS file format,
757     * this class is derived from the DLS::Sample class. So also refer to

908     *
909     * Note: Instead of using MIDI rules, we recommend you using real-time
910     * instrument scripts instead. Read about the reasons below.
911     *
912     * MIDI Rules (also called "iMIDI rules" or "intelligent MIDI rules") were
913     * introduced with GigaStudio 4 as an attempt to increase the power of
914     * potential user controls over sounds. At that point other samplers already
915     * supported certain powerful user control features, which were not possible
916     * with GigaStudio yet. For example triggering new notes by MIDI CC
917     * controller.
918     *
919     * Such extended features however were usually implemented by other samplers
920     * by requiring the sound designer to write an instrument script which the
921     * designer would then bundle with the respective instrument file. Such
922     * scripts are essentially text files, using a very specific programming
923     * language for the purpose of controlling the sampler in real-time. Since
924     * however musicians are not typically keen to writing such cumbersome
925     * script files, the GigaStudio designers decided to implement such extended
926     * features completely without instrument scripts. Instead they created a
927     * set of rules, which could be defined and altered conveniently by mouse
928     * clicks in GSt's instrument editor application. The downside of this
929     * overall approach however, was that those MIDI rules were very limited in
930     * practice. As sound designer you easily came across the possiblities such
931     * MIDI rules were able to offer.
932     *
933     * Due to such severe use case constraints, support for MIDI rules is quite
934     * limited in libgig. At the moment only the "Control Trigger", "Alternator"
935     * and the "Legato" MIDI rules are supported by libgig. Consequently the
936     * graphical instrument editor application gigedit just supports the
937     * "Control Trigger" and "Legato" MIDI rules, and LinuxSampler even does not
938     * support any MIDI rule type at all and LinuxSampler probably will not
939     * support MIDI rules in future either.
940     *
941     * Instead of using MIDI rules, we introduced real-time instrument scripts
942     * as extension to the original GigaStudio file format. This script based
943     * solution is much more powerful than MIDI rules and is already supported
944     * by libgig, gigedit and LinuxSampler.
945     *
946     * @deprecated Just provided for backward compatiblity, use Script for new
947     * instruments instead.

1310     * with libgig. It allows you to open existing .gig files, modifying them
1311     * and saving them persistently either under the same file name or under a
1312     * different location.
1313     *
1314     * A .gig file is merely a monolithic file. That means samples and the
1315     * defintion of the virtual instruments are contained in the same file. A
1316     * .gig file contains an arbitrary amount of samples, and an arbitrary
1317     * amount of instruments which are referencing those samples. It is also
1318     * possible to store samples in .gig files not being referenced by any
1319     * instrument. This is not an error from the file format's point of view and
1320     * it is actually often used in practice during the design phase of new gig
1321     * instruments.
1322     *
1323     * So on toplevel of the gig file format you have:
1324     *
1325     * - A set of samples (see Sample).
1326     * - A set of virtual instruments (see Instrument).
1327     *
1328     * And as extension to the original GigaStudio format, we added:
1329     *
1330     * - Real-time instrument scripts (see Script).
1331     *
1332     * Note that the latter however is only supported by libgig, gigedit and
1333     * LinuxSampler. Scripts are not supported by the original GigaStudio
1334     * software.
1335     *
1336     * All released Gigasampler/GigaStudio file format versions are supported
1337     * (so from first Gigasampler version up to including GigaStudio 4).
1338     *
1339     * Since the gig format was designed as extension to the DLS file format,
1340     * this class is derived from the DLS::File class. So also refer to
1341     * DLS::File for additional informations, class attributes and methods.
