File size: 33934 byte(s)
* 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
  played (default: don't play release trigger sample by sustain pedal).
* Bumped version (4.1.0.svn7).

1 Version SVN trunk (?)
2
3 * src/gig.cpp, src/gig.h:
4 - Fixed Doxygen API comments for enum types (currently latest Doxygen
5 [v1.8.13] only supports C comments in macro arguments expansion, but
6 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
7 the Doxygen source code, which currently also filter out new line
8 \n chars).
9 - Added new method File::CountSamples().
10 - Added new method File::CountInstruments().
11 - Fixed gig v4 files falsely being handled as v2 format
12 (patch by Ivan Maguidhir).
13 - Added gig v4 version identifier (File::VERSION_4).
14 - GIG FORMAT EXTENSION: Added attribute
15 DimensionRegion::SustainReleaseTrigger which allows to define whether
16 a sustain pedal up event shall cause a release trigger sample to be
17 played (default: don't play release trigger sample by sustain pedal).
18
19 * src/Serialization.cpp, src/Serialization.h:
20 - Hide pure internal declarations from header file to avoid numerous
21 compiler warnings when building and linking against the public API.
22
23 * src/RIFF.cpp, src/RIFF.h:
24 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
25 caused a resource leak
26
27 * src/tools/gigdump.cpp:
28 - Added command line option --instrument-names which causes only
29 instrument names and their index numbers to be printed.
30
31 Version 4.1.0 (25 Nov 2017)
32 * general changes:
33 - removed 2 GB limitation when loading a gig or DLS file
34 - using now native integer size where appropriate
35 - fixed minor issues with man pages (patch by Debian maintainer)
36 - fixed various spelling mistakes (patch by Debian maintainer)
37 - Added new "Serialization" framework (and equally named namespace)
38 which allows to serialize and deserialize native C++ objects
39 in a portable, easy and flexible way.
40 - print compiler warning if no RTTI available
41 - Fixed potential crash in command line tools gig2stereo, korg2gig,
42 korgdump and sf2extract.
43 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
44 (original patch by Paul Brossier, slightly modified).
45 - Debian: Fixed packaging error about invalid substitution variable
46 "Source-Version".
47 - Raised Debian compatibility level to Debian 9 "Stretch".
48
49 * src/gig.cpp, src/gig.h:
50 - fixed bug in Script::SetGroup: the script chunk wasn't moved
51 - fixed compilation error with clang 3.4
52 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
53 as one single monolithic gig file. In case .gig file is >= 2GB expect a
54 large monolithic file, otherwise if .gig file is < 2 GB check for
55 "extension" files (.gx01, .gx02, ...) instead.
56 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
57 if there were dimensions after the velocity dimension: it only created
58 valid velocity tables for cases of dimensions lower than the velocity
59 dimension.
60 - added new method Sample::VerifyWaveData() which allows to check whether
61 a sample had been damaged for some reason
62 - Fix: samples' CRC checksums were damaged on file structure changes.
63 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
64 - Added new method Sample::GetWaveDataCRC32Checksum().
65 - Changed default value of EG2Release (filter release time) to 60s.
66 - Instruments' default pitch bend range is now +-2 semi tones.
67 - Fixed CRC checksums being wrong sometimes.
68 - Fix: method File::AddContentOf() did not clone script groups and scripts
69 of passed original file.
70 - Added support for serializing & deserializing DimensionRegion
71 objects (and crossfade_t and leverage_ctrl_t objects).
72 - Added enum reflection API functions for retrieving enum declaration type
73 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
74 - Exception class now has a variadic constructor which allows to add
75 textual format specifiers like with printf().
76 - On unknown leverage controller exception: show precise unknown leverage
77 controller number found.
78 - Ignore invalid leverage controller types and just show a warning on the
79 console instead of throwing an exception.
80 - Added new struct eg_opt_t and new class member variable
81 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
82 extension to the gig file format, which allows to override the default
83 behavior of the first two EGs' state machines.
84 - Fixed undefined behavior when loading a gig file with invalid
85 velocity curve parameters (fixes CVE-2017-12951).
86 - Fixed undefined behavior when loading a gig file with invalid wave
87 pool index number (fixes CVE-2017-12954).
88
89 * src/DLS.cpp, src/DLS.h:
90 - Sample: wave pool offsets are now 64 bits (to allow support for files
91 larger than 4 GB).
92 - Exception class now has a variadic constructor which allows to add
93 textual format specifiers like with printf().
94
95 * src/RIFF.cpp, src/RIFF.h:
96 - added support for RIFF files larger than 4 GB, by default the required
97 internal RIFF file offset size is automatically detected (that is RIFF
98 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
99 automatically use 64 bit offsets), a particular offset size can be forced
100 with a new option added to the RIFF File constructor though
101 - when saving a modified, grown RIFF file, the temporary file size during
102 Save() operation will no longer be larger than the final grown file size
103 - Exception class now has a variadic constructor which allows to add
104 textual format specifiers like with printf().
105
106 * src/Serialization.cpp, src/Serialization.h:
107 - Archive: Added method isModified().
108 - Archive: Added method setAutoValue().
109 - Archive: Added method setIntValue().
110 - Archive: Added method setRealValue().
111 - Archive: Added method setBoolValue().
112 - Archive: Added method setEnumValue().
113 - Archive: Added method valueAsString().
114 - Archive::rawData(): Automatically re-encode new raw data stream if
115 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
116 - Object: Added method memberByUID().
117 - Object: remove() method is now protected.
118 - Archive: Added method removeMember().
119 - Archive: Added methods name() and setName().
120 - Archive: Added methods comment() and setComment().
121 - Archive: Added methods timeStampCreated(), timeStampModified(),
122 dateTimeCreated() and dateTimeModified().
123 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
124 - DataType: Implemented demangling C++ type names (for methods
125 asLongDescr() and customTypeName(bool demangle=false)).
126 - Archive::setAutoValue(): Handle human readable boolean text
127 representations like "yes", "no", "true", "false" as expected.
128 - Exception class now has a variadic constructor which allows to add
129 textual format specifiers like with printf().
130 - DataType fix: Retain backward compatibility to older versions of native
131 C++ classes/structs.
132

152 to recalculate the CRC32 checksum of all samples' raw wave data and
153 rebuilding the gig file's global checksum table (i.e. in case the
154 file's checksum table was damaged)
155 - print samples' CRC32 checksums
156 - Print the new EG behavior options (eg_opt_t).
157
158 * src/tools/gigextract.cpp:
159 - Fix: if sample name contains a path separator (slash or backslash) then
160 replace them by a minus sign to avoid file system issues.

280 one allows to move the subchunk from the current list to another list
281 - POSIX: only assume -1 result value as error on open() calls
282 - POSIX: show operating system's error reason if opening a file failed

380 - write support: the 3crc and einf chunks are now created or
381 updated when a file is saved (3crc contains sample checksums,
382 einf contains file statistics)
383 - write support: DLSID is now generated on the file and the
384 instruments
385 - write support: improved the default values for dimension region
386 parameters

424 - added support for custom splits points for other dimensions than
425 velocity (gig v3 feature)
426 - added "smart midi" and "round robin keyboard" dimensions
427 - added new method File::DeleteGroupOnly() which only deletes the given
428 group but moves all its members to another group, the other method,
429 that is File::DeleteGroup() now removes not just the group, but also
430 all the samples that belong to that group
431 - fixed crash which occured on interfering File::DeleteSample() and
432 File::GetNextSample() calls (due to iterator invalidation)
433 - fixed group names which were not saved

435 with the group
436 - added Instrument::MoveRegion method
437 - fixed constructor for Region, which did not initialize correctly
438 when used from Instrument::AddRegion
439 - when saving, override the gig::Regions sample reference simply by
440 the region's first dimension region's sample (avoids an exception
441 when trying to save a new instrument)
442 - fixed AddDimension() method which did not fill out all mandatory
443 dimension definition fields
444
445 * src/DLS.cpp, src/DLS.h:

467 instead of the wave chunk
468 - keyswitching dimension is changed from split type "normal" to
469 "bit"
470 - real support for 24 bit samples - samples are not truncated to
471 16 bits anymore
472 - support for reading of ".art" files. (Merging of .art and .gig
473 files are not implemented yet.)

494 Version 3.0.0 (28 Apr 2006)
495
496 * general changes:
497 - added write support (that is for creating and modifying RIFF, DLS and
498 gig files)
499 - loading DLS and gig files is now much more permissive, DLS and gig
500 files are now loaded even if mandatory RIFF chunks are missing

505 - fixed the GetVelocityCutoff function, it wasn't always using the
506 VCFVelocityScale parameter when no cutoff controller was defined
507 - support for the gig v3 feature to have a number of dimension
508 splits not equal to a power of two
509 - added write support (highly experimental)

513 seeked instead of ordinary <artl> data chunks)
514 - added write support (highly experimental)
515
516 * src/RIFF.cpp, src/RIFF.h:
517 - added write support
518 - Chunk::LoadChunkData() can now be called again to resize the buffer
519 after a Chunk::Resize() and before the File::Save() call to allow
520 placing the new data in the chunk's write buffer and perform the
521 resize and write operations in one rush
522
523 * src/gigdump.cpp:
524 - fixed to show the correct amount of dimension regions instead of 32
525 (patch by James Wylder)
526

574 * src/gig.cpp, src/gig.h:
575 - experimental support for Gigasampler v3 format;
576 64 bit file offsets are truncated to 32 bit, 24 bit samples are
577 truncated to 16 bit, up to 8 dimensions are read, additional
578 articulation informations are ignored at the moment
579 (patch by Andreas Persson)
580 - added some file format compatibility checks
581 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
582 never used, because the necessary check was made before

631
632 * packaging changes:
633 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
634 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
635 - fixed man pages automake install rule (which didn't work on Mandrake,
636 SuSE and Fedora)
637 - fixed generation of Doxygen API documentation (now also included in
638 RPM and Debian packages)
639
640 * src/gig.cpp, src/gig.h:
641 - fixed / improved accuracy of all three velocity to volume
642 transformation functions a.k.a. 'nonlinear','linear','special'
643 (patch by Andreas Persson)
644 - denormals are filtered from the velocity to volume tables
645 - bugfix for dimension region switching (wrong handling of the release
646 trigger dimension, no bit range check for dimensions of split type
647 'split_type_bit')

649 signed 7 bit to signed 8 bit)
650 - added class attribute 'Layers' to class 'gig::Region'
651 - symbol prototyping of gig::Region (fixes build failure with qsampler)
652

660 - added printout for crossfade definitions
661 - added printout for panorama value for each DimensionRegion
662 - replaced printout of DLS Region layer by printout of amount of
663 Gigasampler layers
664
665 Version 0.7.1 (2 Jul 2004)
666
667 * packaging changes:
668 - added libgig.spec and libgig.pc package configurations for generating
669 Redhat packages
670 - header files included on installation.
671 - autotools-generated files removed from CVS repository.
672 - added support for generating Debian packages
673 - version of shared library can be set in configure.in
674
675 Version 0.7.0 (3 May 2004)
676
677 * general changes:
678 - various big endian specific corrections
679 (successfully tested now on PPC)
680 - minor adjustments to avoid compile errors on some systems
681 (using now pow() instead of powl() and --pedantic g++ compiler switch)
682 - libtoolized the library
683 - added man pages for the command line tools
684 (gigextract, gigdump, dlsdump, rifftree)
685
686 * src/gig.cpp, src/gig.h:
687 - fixed bug in decompression algorithm which caused it not to detect
688 the end of a stream
689 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
690 takes the MIDI key velocity value as an argument and returns the
691 appropriate volume factor (0.0 ... 1.0) for the sample to be played
692 back, the velocity curve transformation functions used for this are
693 only an approximation so far
694 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
695 'Sample::LoopSize' which reflected wrong values
696 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
697 measured in sample points instead of byte offset
698 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
699 'Sample::FineTune'
700 - added class attribute 'Sample::LoopSize'
701 - added method GetInstrument(uint index) to class 'File'
702 - added ReadAndLoop() method to class 'Sample' which is an extension to
703 the normal Read() method to honor the sample's looping information
704 while streaming from disk
705 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
706 'eg2_ctrl_t': replaced this huge enumeration by a structure which
707 reflects the MIDI controller number in case of an ordinary control
708 change controller (this saves a huge switch-case block in the
709 application of the library user)
710 - renamed following attributes in class 'DimensionRegion':
711 'AttenuationContol' -> 'AttenuationController',
712 'InvertAttenuationControl' -> 'InvertAttenuationController',
713 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
714 - minor fix in API documentation for method GetVelocityAttenuation() in
715 class 'DimensionRegion'
716
717 * src/RIFF.cpp, src/RIFF.h:
718 - added additional API documentation
719 - minor fix in Chunk::Read() method (only a minor efficiency issue)
720
721 * src/gigdump.cpp:
722 - added printout of samples' looping informations
723
724 Version 0.6.0 (3 Nov 2003)
725
726 * initial release
