* RIFF: Use GetSubListAt() instead of GetFirstSubList() /
  GetNextSubList() in entire RIFF.cpp file.

* Bumped version (4.3.0.svn11).

1 Version SVN trunk (?)
2
3 * src/gig.cpp, src/gig.h:
4 - Region::DeleteDimensionZone(): Fix clang sanatizer warning.
5 - Region::SplitDimensionZone(): Fix clang sanatizer warning.
6 - Sample: Fix unnecessary RAM consumption in case of 24 bit samples
7 (InternalDecompressionBuffer is no longer needed for 24 bit samples since
8 SVN r902 / libgig release 3.1.0).
9
10 * src/SF.cpp, src/SF.h:
11 - File::DeleteInstrument(): Fix clang sanatizer warning.
12
13 * src/RIFF.cpp, src/RIFF.h:
14 - Chunk::LoadChunkData(): Fix clang sanatizer warning.
15 - List::LoadSubChunks(): Fix potential garbage data access if reading a
16 RIFF chunk ID failed.
17 - Added methods File::IsIOPerThread() and File::SetIOPerThread(bool); the
18 latter allows to automatically use a separate file I/O stream state for
19 each thread.
20 - Added method List::GetSubChunkAt().
21 - Added method List::GetSubListAt().
22 - Marked methods List::GetFirstSubChunk(), List::GetNextSubChunk(),
23 List::GetFirstSubList() and List::GetNextSubList() as deprecated.
24 - Use GetSubListAt() instead of GetFirstSubList() / GetNextSubList() in
25 entire RIFF.cpp file.
26
27 Version 4.3.0 (9 May 2021)
28
29 * general changes:
30 - Require at least a C++11 compliant compiler.
31 - Require some UUID generating function by underlying system.
32
33 * src/gig.cpp, src/gig.h:
34 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
35 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
36 allow to define override LFOs' wave form (e.g. saw or square instead of
37 the default wave form which was always sine in the original
38 Gigasampler/GigaStudio software).
39 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
40 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
41 move the start point horizontally of the LFOs' waves (0�� ... 360��).
42 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
43 (the original Gigasampler/GigaStudio software only had that flip phase
44 option for LFO1 and LFO2).
45 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
46 Region::UsesAnyGigFormatExtension(),
47 Instrument::UsesAnyGigFormatExtension() and
48 File::UsesAnyGigFormatExtension() (however only as private methods yet,
49 see comments on methods why).
50 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
51 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
52 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
53 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
54 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
55 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
56 (patch by Ivan Maguidhir).
57 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
58 (original patch by Ivan Maguidhir).
59 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
60 dimensions being in different order after deleting a dimension zone.
61 - Script: Generate a persistent UUID for each script.
62 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
63 accordingly added new methods to Instrument class:
64 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
65 GetScriptPatchVariable(), SetScriptPatchVariable(),
66 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
67 as child of our '3LS ' list chunk on Instrument level.
68 - Fixed undefined behaviour when modifying script slots on an instrument
69 that had been cloned and not been saved yet (e.g. unintended modification
70 of original instrument's script slots, and crash on Instrument destruction
71 due to double free of pScriptRefs).
72
73 * src/Serialization.cpp, src/Serialization.h:
74 - Fixed broken Archive(RawData) constructor which always threw an
75 Exception.
76 - Added built-in support for C++ String objects (a.k.a. std::string
77 from the STL) and bumped Srx format version to 1.1 for that reason.
78 - Fixed assertion fault on some systems if a member variable defined was
79 serialized which was declared as size_t or ssize_t data type.
80 - Added new method Archive::operation() which allows applications to
81 distinguish between serialization vs. deserialization in their
82 serialize() method implementations.
83 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
84 the STL).
85 - Member offsets are now signed and for (newly added support of) member
86 variables on the heap -1 is always used as offset instead.
87 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
88 STL).
89 - DataType: Added optional 2nd custom type name.
90 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
91 STL).
92
93 * src/helper.h:
94 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
95 function call.
96
97 * src/tools/gigdump.cpp:
98 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
99 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
100 LFO2FlipPhase and LFO3FlipPhase.
101
102 Version 4.2.0 (25 Jul 2019)
103
104 * general changes:
105 - Added MSVC build support (anonymous patch from mailing list).
106 - Introduced CMake build support (yet constrained for building with MSVC)
107 (anonymous patch from mailing list).
108 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
109 destructors. Added new virtual method DeleteChunks() to those classes
110 for this which must be explicitly called instead to remove their RIFF
111 chunks.
112 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
113 of zero; which is unsafe per se.
114 - Added C++11 "override" keyword where appropriate.
115 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
116 of their actions when not passing a progress_t callback structure.
117
118 * src/gig.cpp, src/gig.h:
119 - Fixed Doxygen API comments for enum types (currently latest Doxygen
120 [v1.8.13] only supports C comments in macro arguments expansion, but
121 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
122 the Doxygen source code, which currently also filter out new line
123 \n chars).
124 - Added new method File::CountSamples().
125 - Added new method File::CountInstruments().
126 - Fixed gig v4 files falsely being handled as v2 format
127 (patch by Ivan Maguidhir).
128 - Added gig v4 version identifier (File::VERSION_4).
129 - GIG FORMAT EXTENSION: Added attribute
130 DimensionRegion::SustainReleaseTrigger which allows to define whether
131 a sustain pedal up event shall cause a release trigger sample to be
132 played (default: don't play release trigger sample by sustain pedal).
133 - GIG FORMAT EXTENSION: Added attribute
134 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
135 regular behaviour of playing release trigger sample on MIDI note-off
136 events.
137 - Introduced support for writing extension files (.gx01, .gx02, ...)
138 (original patch by Ivan Maguidhir).
139 - Many gig classes derive now from DLS::Storage (see DLS changes below).
140 - Added File::GetRiffFile() method.
141
142 * src/DLS.cpp, src/DLS.h:
143 - File: Fixed implicitly allocated RIFF::File object never been freed.
144 - Added new abstract interface base class DLS::Storage which is derived by
145 the respective classes for implementing (the old) UpdateChunks() and the
146 new DeleteChunks() method.
147 - Added File::GetRiffFile() method.
148
149 * src/sf2.cpp, src/sf2.h:
150 - Added Sample::GetFile() method.
151 - Added File::GetRiffFile() method.
152
153 * src/Serialization.cpp, src/Serialization.h:
154 - Hide pure internal declarations from header file to avoid numerous
155 compiler warnings when building and linking against the public API.
156 - Fixed comparision logic bug
157 - Fixed memory leak in DataType::customTypeName().
158
159 * src/RIFF.cpp, src/RIFF.h:
160 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
161 caused a resource leak
162 - Avoid compiler warning when building for 32 bit windows.
163 - Added new method progress_t::subdivide().
164 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
165 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
166 allows a more fine graded control into which portions the subtasks are
167 divided to.
168
169 * src/tools/gigdump.cpp:
170 - Added command line option --instrument-names which causes only
171 instrument names and their index numbers to be printed.
172
173 Version 4.1.0 (25 Nov 2017)
174 * general changes:
175 - removed 2 GB limitation when loading a gig or DLS file
176 - using now native integer size where appropriate
177 - fixed minor issues with man pages (patch by Debian maintainer)
178 - fixed various spelling mistakes (patch by Debian maintainer)
179 - Added new "Serialization" framework (and equally named namespace)
180 which allows to serialize and deserialize native C++ objects
181 in a portable, easy and flexible way.
182 - print compiler warning if no RTTI available
183 - Fixed potential crash in command line tools gig2stereo, korg2gig,
184 korgdump and sf2extract.
185 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
186 (original patch by Paul Brossier, slightly modified).
187 - Debian: Fixed packaging error about invalid substitution variable
188 "Source-Version".
189 - Raised Debian compatibility level to Debian 9 "Stretch".
190
191 * src/gig.cpp, src/gig.h:
192 - fixed bug in Script::SetGroup: the script chunk wasn't moved
193 - fixed compilation error with clang 3.4
194 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
195 as one single monolithic gig file. In case .gig file is >= 2GB expect a
196 large monolithic file, otherwise if .gig file is < 2 GB check for
197 "extension" files (.gx01, .gx02, ...) instead.
198 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
199 if there were dimensions after the velocity dimension: it only created
200 valid velocity tables for cases of dimensions lower than the velocity
201 dimension.
202 - added new method Sample::VerifyWaveData() which allows to check whether
203 a sample had been damaged for some reason
204 - Fix: samples' CRC checksums were damaged on file structure changes.
205 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
206 - Added new method Sample::GetWaveDataCRC32Checksum().
207 - Changed default value of EG2Release (filter release time) to 60s.
208 - Instruments' default pitch bend range is now +-2 semi tones.
209 - Fixed CRC checksums being wrong sometimes.
210 - Fix: method File::AddContentOf() did not clone script groups and scripts
211 of passed original file.
212 - Added support for serializing & deserializing DimensionRegion
213 objects (and crossfade_t and leverage_ctrl_t objects).
214 - Added enum reflection API functions for retrieving enum declaration type
215 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
216 - Exception class now has a variadic constructor which allows to add
217 textual format specifiers like with printf().
218 - On unknown leverage controller exception: show precise unknown leverage
219 controller number found.
220 - Ignore invalid leverage controller types and just show a warning on the
221 console instead of throwing an exception.
222 - Added new struct eg_opt_t and new class member variable
223 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
224 extension to the gig file format, which allows to override the default
225 behavior of the first two EGs' state machines.
226 - Fixed undefined behavior when loading a gig file with invalid
227 velocity curve parameters (fixes CVE-2017-12951).
228 - Fixed undefined behavior when loading a gig file with invalid wave
229 pool index number (fixes CVE-2017-12954).
230
231 * src/DLS.cpp, src/DLS.h:
232 - Sample: wave pool offsets are now 64 bits (to allow support for files
233 larger than 4 GB).
234 - Exception class now has a variadic constructor which allows to add
235 textual format specifiers like with printf().
236
237 * src/RIFF.cpp, src/RIFF.h:
238 - added support for RIFF files larger than 4 GB, by default the required
239 internal RIFF file offset size is automatically detected (that is RIFF
240 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
241 automatically use 64 bit offsets), a particular offset size can be forced
242 with a new option added to the RIFF File constructor though
243 - when saving a modified, grown RIFF file, the temporary file size during
244 Save() operation will no longer be larger than the final grown file size
245 - Exception class now has a variadic constructor which allows to add
246 textual format specifiers like with printf().
247
248 * src/Serialization.cpp, src/Serialization.h:
249 - Archive: Added method isModified().
250 - Archive: Added method setAutoValue().
251 - Archive: Added method setIntValue().
252 - Archive: Added method setRealValue().
253 - Archive: Added method setBoolValue().
254 - Archive: Added method setEnumValue().
255 - Archive: Added method valueAsString().
256 - Archive::rawData(): Automatically re-encode new raw data stream if
257 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
258 - Object: Added method memberByUID().
259 - Object: remove() method is now protected.
260 - Archive: Added method removeMember().
261 - Archive: Added methods name() and setName().
262 - Archive: Added methods comment() and setComment().
263 - Archive: Added methods timeStampCreated(), timeStampModified(),
264 dateTimeCreated() and dateTimeModified().
265 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
266 - DataType: Implemented demangling C++ type names (for methods
267 asLongDescr() and customTypeName(bool demangle=false)).
268 - Archive::setAutoValue(): Handle human readable boolean text
269 representations like "yes", "no", "true", "false" as expected.
270 - Exception class now has a variadic constructor which allows to add
271 textual format specifiers like with printf().
272 - DataType fix: Retain backward compatibility to older versions of native
273 C++ classes/structs.
274
275 * src/Akai.cpp:
276 - Fixed compilation error with recent, more strict compilers.
277

290 data
291 - added and implemented new parameter "--verify" which allows to check
292 the raw wave form data integrity of all samples
293 - added and implemented new parameter "--rebuild-checksums" which allows
294 to recalculate the CRC32 checksum of all samples' raw wave data and
295 rebuilding the gig file's global checksum table (i.e. in case the
296 file's checksum table was damaged)
297 - print samples' CRC32 checksums
298 - Print the new EG behavior options (eg_opt_t).
299
300 * src/tools/gigextract.cpp:
301 - Fix: if sample name contains a path separator (slash or backslash) then
302 replace them by a minus sign to avoid file system issues.
303
304 * src/tools/gig2stereo.cpp:
305 - Also merge mono sample pairs with non matching loop information if
306 argument --incompatible was given.
307
308 * packaging changes:
309 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
310 auto detect whether it (sh/c)ould output its messages in color.

345
346 * AKAI file format:
347 - Added Linux/POSIX ported version of libakai. Note that libakai is released
348 under LGPL terms while libgig is released under GPL terms. To handle this

428 - Cleanup of an old DLL binary backward compatibility hack.
429
430 * src/gigextract.cpp:
431 - export sample loop, unity note and fine tune with libsndfile

452 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
453
454 * src/RIFF.cpp, src/RIFF.h:
455 - bugfix: saving to the same file after the file size had been
456 increased made the file corrupt (#82)
457 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
458 is not written physically yet (#82)
459 - bugfix: saving to the same file after the file size had been

461 - bugfix: undefined behavior (e.g. endless loop) when opening zero
462 length files, now throws a RIFF::Exception instead (fixes bug #121)
463 - bugfix: destructor for base class RIFF::Chunk accessed members
464 of derived class RIFF::File, which is bad, and caused crashes
465 when using Visual C++
466 - bugfix: files that contain zero length RIFF lists were not read
467 correctly (fixes #127) (bug was introduced 2009-03-13)

508 - added missing parameter initalizations in sample, region and
509 instrument constructors
510 - clear unused fields when saving samples and regions
511 - fixed write support bugs: v3 dimension limits and chunksize
512 weren't saved, leverage controller of type controlchange

526 instruments
527 - write support: improved the default values for dimension region
528 parameters
529 - more write support fixes: crossfade parameters were not saved,
530 v3 dimension limits were not correctly initialized and saved
531 when dimensions were added or deleted, v3 wave pool offsets were
532 not saved correctly
533 - write support: 24 bit samples can now be written
534 - write support: version 3 is now the default for new files
535 - more write support fixes: the 3ewg chunk is now bigger for v3,
536 dimension regions without mapped samples are now allowed, 3gnl
537 list in v3 files now always has 128 entries, several parameters
538 where incorrectly saved due to an operator precedence mistake
539 - DeleteSample now removes all references to the deleted sample
540 - AddDimension now copies all parameters from existing dimension
541 regions and also makes sure that the samplechannel dimension is
542 placed first in the list of dimensions.
543 - added method GetParent() to class 'DimensionRegion', which returns its
544 parent Region
545 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
546 unused areas
547 - added various setter methods to DimensionRegion class which take care
548 of updating lookup tables / caches.
549

565 - custom velocity splits now works for gig v3 files too
566 - added support for custom splits points for other dimensions than
567 velocity (gig v3 feature)
568 - added "smart midi" and "round robin keyboard" dimensions
569 - added new method File::DeleteGroupOnly() which only deletes the given
570 group but moves all its members to another group, the other method,
571 that is File::DeleteGroup() now removes not just the group, but also
572 all the samples that belong to that group
573 - fixed crash which occured on interfering File::DeleteSample() and
574 File::GetNextSample() calls (due to iterator invalidation)
575 - fixed group names which were not saved
576 - fixed group destructor which did not remove the RIFF chunk associated
577 with the group
578 - added Instrument::MoveRegion method
579 - fixed constructor for Region, which did not initialize correctly
580 when used from Instrument::AddRegion
581 - when saving, override the gig::Regions sample reference simply by
582 the region's first dimension region's sample (avoids an exception
583 when trying to save a new instrument)
584 - fixed AddDimension() method which did not fill out all mandatory
585 dimension definition fields
586
587 * src/DLS.cpp, src/DLS.h:

720 articulation informations are ignored at the moment
721 (patch by Andreas Persson)
722 - added some file format compatibility checks
723 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

777 - fixed man pages automake install rule (which didn't work on Mandrake,
778 SuSE and Fedora)
779 - fixed generation of Doxygen API documentation (now also included in
780 RPM and Debian packages)
781
782 * src/gig.cpp, src/gig.h:
783 - fixed / improved accuracy of all three velocity to volume
784 transformation functions a.k.a. 'nonlinear','linear','special'
785 (patch by Andreas Persson)
786 - denormals are filtered from the velocity to volume tables
787 - bugfix for dimension region switching (wrong handling of the release
788 trigger dimension, no bit range check for dimensions of split type
789 'split_type_bit')
790 - fixed panorama value in DimensionRegion (invalid conversion from
791 signed 7 bit to signed 8 bit)
792 - added class attribute 'Layers' to class 'gig::Region'
793 - symbol prototyping of gig::Region (fixes build failure with qsampler)
794

812 - header files included on installation.
813 - autotools-generated files removed from CVS repository.
814 - added support for generating Debian packages
815 - version of shared library can be set in configure.in
816
817 Version 0.7.0 (3 May 2004)
818
819 * general changes:
820 - various big endian specific corrections
821 (successfully tested now on PPC)
822 - minor adjustments to avoid compile errors on some systems
823 (using now pow() instead of powl() and --pedantic g++ compiler switch)
824 - libtoolized the library
825 - added man pages for the command line tools
826 (gigextract, gigdump, dlsdump, rifftree)
827
828 * src/gig.cpp, src/gig.h:
829 - fixed bug in decompression algorithm which caused it not to detect
830 the end of a stream
831 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
832 takes the MIDI key velocity value as an argument and returns the
833 appropriate volume factor (0.0 ... 1.0) for the sample to be played
834 back, the velocity curve transformation functions used for this are
835 only an approximation so far
836 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
837 'Sample::LoopSize' which reflected wrong values
838 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
839 measured in sample points instead of byte offset
840 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
841 'Sample::FineTune'
842 - added class attribute 'Sample::LoopSize'
843 - added method GetInstrument(uint index) to class 'File'
844 - added ReadAndLoop() method to class 'Sample' which is an extension to
845 the normal Read() method to honor the sample's looping information
846 while streaming from disk
847 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
848 'eg2_ctrl_t': replaced this huge enumeration by a structure which
849 reflects the MIDI controller number in case of an ordinary control
850 change controller (this saves a huge switch-case block in the
851 application of the library user)
852 - renamed following attributes in class 'DimensionRegion':
853 'AttenuationContol' -> 'AttenuationController',
854 'InvertAttenuationControl' -> 'InvertAttenuationController',
855 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
856 - minor fix in API documentation for method GetVelocityAttenuation() in
857 class 'DimensionRegion'
858
859 * src/RIFF.cpp, src/RIFF.h:
860 - added additional API documentation
861 - minor fix in Chunk::Read() method (only a minor efficiency issue)
862
863 * src/gigdump.cpp:
864 - added printout of samples' looping informations
865
866 Version 0.6.0 (3 Nov 2003)
867
868 * initial release
