65 Version 4.3.0 (9 May 2021)
66
67 * general changes:
68 - Require at least a C++11 compliant compiler.
69 - Require some UUID generating function by underlying system.
70
71 * src/gig.cpp, src/gig.h:
72 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
73 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
74 allow to define override LFOs' wave form (e.g. saw or square instead of
75 the default wave form which was always sine in the original
76 Gigasampler/GigaStudio software).
77 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
78 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
79 move the start point horizontally of the LFOs' waves (0�� ... 360��).
80 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
81 (the original Gigasampler/GigaStudio software only had that flip phase
82 option for LFO1 and LFO2).
83 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
84 Region::UsesAnyGigFormatExtension(),
85 Instrument::UsesAnyGigFormatExtension() and
86 File::UsesAnyGigFormatExtension() (however only as private methods yet,
87 see comments on methods why).
88 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
89 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
90 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
91 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
92 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
93 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
94 (patch by Ivan Maguidhir).
95 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
96 (original patch by Ivan Maguidhir).
97 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
98 dimensions being in different order after deleting a dimension zone.
99 - Script: Generate a persistent UUID for each script.
100 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
101 accordingly added new methods to Instrument class:
102 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
103 GetScriptPatchVariable(), SetScriptPatchVariable(),
104 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
105 as child of our '3LS ' list chunk on Instrument level.
106 - Fixed undefined behaviour when modifying script slots on an instrument
107 that had been cloned and not been saved yet (e.g. unintended modification
108 of original instrument's script slots, and crash on Instrument destruction
109 due to double free of pScriptRefs).
110
111 * src/Serialization.cpp, src/Serialization.h:
112 - Fixed broken Archive(RawData) constructor which always threw an
113 Exception.
114 - Added built-in support for C++ String objects (a.k.a. std::string
115 from the STL) and bumped Srx format version to 1.1 for that reason.
116 - Fixed assertion fault on some systems if a member variable defined was
117 serialized which was declared as size_t or ssize_t data type.
118 - Added new method Archive::operation() which allows applications to
119 distinguish between serialization vs. deserialization in their
120 serialize() method implementations.
121 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
122 the STL).
123 - Member offsets are now signed and for (newly added support of) member
124 variables on the heap -1 is always used as offset instead.
125 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
126 STL).
127 - DataType: Added optional 2nd custom type name.
128 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
129 STL).
130
131 * src/helper.h:
132 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
133 function call.
134
135 * src/tools/gigdump.cpp:
136 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
137 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
138 LFO2FlipPhase and LFO3FlipPhase.
139
140 Version 4.2.0 (25 Jul 2019)
141
142 * general changes:
143 - Added MSVC build support (anonymous patch from mailing list).
144 - Introduced CMake build support (yet constrained for building with MSVC)
145 (anonymous patch from mailing list).
146 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
147 destructors. Added new virtual method DeleteChunks() to those classes
148 for this which must be explicitly called instead to remove their RIFF
149 chunks.
150 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
151 of zero; which is unsafe per se.
152 - Added C++11 "override" keyword where appropriate.
153 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
154 of their actions when not passing a progress_t callback structure.
155
156 * src/gig.cpp, src/gig.h:
157 - Fixed Doxygen API comments for enum types (currently latest Doxygen
158 [v1.8.13] only supports C comments in macro arguments expansion, but
159 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
160 the Doxygen source code, which currently also filter out new line
161 \n chars).
162 - Added new method File::CountSamples().
163 - Added new method File::CountInstruments().
164 - Fixed gig v4 files falsely being handled as v2 format
165 (patch by Ivan Maguidhir).
166 - Added gig v4 version identifier (File::VERSION_4).
167 - GIG FORMAT EXTENSION: Added attribute
168 DimensionRegion::SustainReleaseTrigger which allows to define whether
169 a sustain pedal up event shall cause a release trigger sample to be
170 played (default: don't play release trigger sample by sustain pedal).
171 - GIG FORMAT EXTENSION: Added attribute
172 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
173 regular behaviour of playing release trigger sample on MIDI note-off
174 events.
175 - Introduced support for writing extension files (.gx01, .gx02, ...)
176 (original patch by Ivan Maguidhir).
177 - Many gig classes derive now from DLS::Storage (see DLS changes below).
178 - Added File::GetRiffFile() method.
179
180 * src/DLS.cpp, src/DLS.h:
181 - File: Fixed implicitly allocated RIFF::File object never been freed.
182 - Added new abstract interface base class DLS::Storage which is derived by
183 the respective classes for implementing (the old) UpdateChunks() and the
184 new DeleteChunks() method.
185 - Added File::GetRiffFile() method.
186
187 * src/sf2.cpp, src/sf2.h:
188 - Added Sample::GetFile() method.
189 - Added File::GetRiffFile() method.
190
191 * src/Serialization.cpp, src/Serialization.h:
192 - Hide pure internal declarations from header file to avoid numerous
193 compiler warnings when building and linking against the public API.
194 - Fixed comparision logic bug
195 - Fixed memory leak in DataType::customTypeName().
196
197 * src/RIFF.cpp, src/RIFF.h:
198 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
199 caused a resource leak
200 - Avoid compiler warning when building for 32 bit windows.
201 - Added new method progress_t::subdivide().
202 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
203 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
204 allows a more fine graded control into which portions the subtasks are
205 divided to.
206
207 * src/tools/gigdump.cpp:
208 - Added command line option --instrument-names which causes only
209 instrument names and their index numbers to be printed.
210
211 Version 4.1.0 (25 Nov 2017)
212 * general changes:
213 - removed 2 GB limitation when loading a gig or DLS file
214 - using now native integer size where appropriate
215 - fixed minor issues with man pages (patch by Debian maintainer)
216 - fixed various spelling mistakes (patch by Debian maintainer)
217 - Added new "Serialization" framework (and equally named namespace)
218 which allows to serialize and deserialize native C++ objects
219 in a portable, easy and flexible way.
220 - print compiler warning if no RTTI available
221 - Fixed potential crash in command line tools gig2stereo, korg2gig,
222 korgdump and sf2extract.
223 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
224 (original patch by Paul Brossier, slightly modified).
225 - Debian: Fixed packaging error about invalid substitution variable
226 "Source-Version".
227 - Raised Debian compatibility level to Debian 9 "Stretch".
228
229 * src/gig.cpp, src/gig.h:
230 - fixed bug in Script::SetGroup: the script chunk wasn't moved
231 - fixed compilation error with clang 3.4
232 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
233 as one single monolithic gig file. In case .gig file is >= 2GB expect a
234 large monolithic file, otherwise if .gig file is < 2 GB check for
235 "extension" files (.gx01, .gx02, ...) instead.
236 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
237 if there were dimensions after the velocity dimension: it only created
238 valid velocity tables for cases of dimensions lower than the velocity
239 dimension.
240 - added new method Sample::VerifyWaveData() which allows to check whether
241 a sample had been damaged for some reason
242 - Fix: samples' CRC checksums were damaged on file structure changes.
243 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
244 - Added new method Sample::GetWaveDataCRC32Checksum().
245 - Changed default value of EG2Release (filter release time) to 60s.
246 - Instruments' default pitch bend range is now +-2 semi tones.
247 - Fixed CRC checksums being wrong sometimes.
248 - Fix: method File::AddContentOf() did not clone script groups and scripts
249 of passed original file.
250 - Added support for serializing & deserializing DimensionRegion
251 objects (and crossfade_t and leverage_ctrl_t objects).
252 - Added enum reflection API functions for retrieving enum declaration type
253 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
254 - Exception class now has a variadic constructor which allows to add
255 textual format specifiers like with printf().
256 - On unknown leverage controller exception: show precise unknown leverage
257 controller number found.
258 - Ignore invalid leverage controller types and just show a warning on the
259 console instead of throwing an exception.
260 - Added new struct eg_opt_t and new class member variable
261 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
262 extension to the gig file format, which allows to override the default
263 behavior of the first two EGs' state machines.
264 - Fixed undefined behavior when loading a gig file with invalid
265 velocity curve parameters (fixes CVE-2017-12951).
266 - Fixed undefined behavior when loading a gig file with invalid wave
267 pool index number (fixes CVE-2017-12954).
268
269 * src/DLS.cpp, src/DLS.h:
270 - Sample: wave pool offsets are now 64 bits (to allow support for files
271 larger than 4 GB).
272 - Exception class now has a variadic constructor which allows to add
273 textual format specifiers like with printf().
274
275 * src/RIFF.cpp, src/RIFF.h:
276 - added support for RIFF files larger than 4 GB, by default the required
277 internal RIFF file offset size is automatically detected (that is RIFF
278 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
279 automatically use 64 bit offsets), a particular offset size can be forced
280 with a new option added to the RIFF File constructor though
281 - when saving a modified, grown RIFF file, the temporary file size during
282 Save() operation will no longer be larger than the final grown file size
283 - Exception class now has a variadic constructor which allows to add
284 textual format specifiers like with printf().
285
286 * src/Serialization.cpp, src/Serialization.h:
287 - Archive: Added method isModified().
288 - Archive: Added method setAutoValue().
289 - Archive: Added method setIntValue().
290 - Archive: Added method setRealValue().
291 - Archive: Added method setBoolValue().
292 - Archive: Added method setEnumValue().
293 - Archive: Added method valueAsString().
294 - Archive::rawData(): Automatically re-encode new raw data stream if
295 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
296 - Object: Added method memberByUID().
297 - Object: remove() method is now protected.
298 - Archive: Added method removeMember().
299 - Archive: Added methods name() and setName().
300 - Archive: Added methods comment() and setComment().
301 - Archive: Added methods timeStampCreated(), timeStampModified(),
302 dateTimeCreated() and dateTimeModified().
303 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
304 - DataType: Implemented demangling C++ type names (for methods
305 asLongDescr() and customTypeName(bool demangle=false)).
306 - Archive::setAutoValue(): Handle human readable boolean text
307 representations like "yes", "no", "true", "false" as expected.
308 - Exception class now has a variadic constructor which allows to add
309 textual format specifiers like with printf().
310 - DataType fix: Retain backward compatibility to older versions of native
311 C++ classes/structs.
312
313 * src/Akai.cpp:
314 - Fixed compilation error with recent, more strict compilers.
315
316 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
317 - improved output of non-ascii characters in usage messages

328 data
329 - added and implemented new parameter "--verify" which allows to check
330 the raw wave form data integrity of all samples
331 - added and implemented new parameter "--rebuild-checksums" which allows
332 to recalculate the CRC32 checksum of all samples' raw wave data and
333 rebuilding the gig file's global checksum table (i.e. in case the
334 file's checksum table was damaged)
335 - print samples' CRC32 checksums
336 - Print the new EG behavior options (eg_opt_t).
337
338 * src/tools/gigextract.cpp:
339 - Fix: if sample name contains a path separator (slash or backslash) then
340 replace them by a minus sign to avoid file system issues.
341
342 * src/tools/gig2stereo.cpp:
343 - Also merge mono sample pairs with non matching loop information if
344 argument --incompatible was given.
345
346 * packaging changes:
347 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
348 auto detect whether it (sh/c)ould output its messages in color.

383
384 * AKAI file format:
385 - Added Linux/POSIX ported version of libakai. Note that libakai is released

426 (chunks at wrong location in the RIFF tree).
427 - Added new method Instrument::MoveTo() which allows to rearrange the order
428 of instruments within the same gig file.
429

475 Version 3.3.0 (30 Jul 2009)
476
477 * general changes:
478 - fixed compilation with gcc 4.3
479 - fixes for building with Visual C++
480 - minor fix in configure for building DLL on Windows
481
482 * src/gig.cpp, src/gig.h:
483 - added partial support for MIDI rules, only the Controller
484 Triggered rule is supported so far
485 - bugfix: removed another iterator invalidation in DeleteSample
486 - bugfix in Sample::LoadSampleData*(): reset sample read position to
487 sample start before trying to (re)load sample data from file (#82)
488 - bugfix: EG3 depth parameter was not saved correctly
489 - fixed crash which occured when streaming a gig sample with
490 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
491
492 * src/RIFF.cpp, src/RIFF.h:
493 - bugfix: saving to the same file after the file size had been
494 increased made the file corrupt (#82)
495 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
496 is not written physically yet (#82)
497 - bugfix: saving to the same file after the file size had been
498 decreased sometimes also made the file corrupt!
499 - bugfix: undefined behavior (e.g. endless loop) when opening zero
500 length files, now throws a RIFF::Exception instead (fixes bug #121)
501 - bugfix: destructor for base class RIFF::Chunk accessed members
502 of derived class RIFF::File, which is bad, and caused crashes
503 when using Visual C++
504 - bugfix: files that contain zero length RIFF lists were not read
505 correctly (fixes #127) (bug was introduced 2009-03-13)

519
520 * packaging changes:
521 - added Mac OSX XCode project files (patch by Toshi Nagata)

545 are saved when the file is written, even if they are empty.
546 - added missing parameter initalizations in sample, region and
547 instrument constructors
548 - clear unused fields when saving samples and regions
549 - fixed write support bugs: v3 dimension limits and chunksize
550 weren't saved, leverage controller of type controlchange
551 couldn't be saved, group name list chunk was placed wrong,
552 dimension region chunks also placed wrong
553 - added initialization of some fixed info strings in file and
554 instrument
555 - write support: files created by libgig will now have the RIFF
556 chunks in correct order

563 - write support: DLSID is now generated on the file and the
564 instruments
565 - write support: improved the default values for dimension region
566 parameters
567 - more write support fixes: crossfade parameters were not saved,
568 v3 dimension limits were not correctly initialized and saved
569 when dimensions were added or deleted, v3 wave pool offsets were
570 not saved correctly
571 - write support: 24 bit samples can now be written
572 - write support: version 3 is now the default for new files
573 - more write support fixes: the 3ewg chunk is now bigger for v3,
574 dimension regions without mapped samples are now allowed, 3gnl
575 list in v3 files now always has 128 entries, several parameters
576 where incorrectly saved due to an operator precedence mistake
577 - DeleteSample now removes all references to the deleted sample
578 - AddDimension now copies all parameters from existing dimension
579 regions and also makes sure that the samplechannel dimension is
580 placed first in the list of dimensions.
581 - added method GetParent() to class 'DimensionRegion', which returns its
582 parent Region
583 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
584 unused areas
585 - added various setter methods to DimensionRegion class which take care
586 of updating lookup tables / caches.
587

601
602 * src/gig.cpp, src/gig.h:
603 - custom velocity splits now works for gig v3 files too
604 - added support for custom splits points for other dimensions than
605 velocity (gig v3 feature)
606 - added "smart midi" and "round robin keyboard" dimensions
607 - added new method File::DeleteGroupOnly() which only deletes the given
608 group but moves all its members to another group, the other method,
609 that is File::DeleteGroup() now removes not just the group, but also
610 all the samples that belong to that group
611 - fixed crash which occured on interfering File::DeleteSample() and
612 File::GetNextSample() calls (due to iterator invalidation)
613 - fixed group names which were not saved
614 - fixed group destructor which did not remove the RIFF chunk associated
615 with the group
616 - added Instrument::MoveRegion method
617 - fixed constructor for Region, which did not initialize correctly
618 when used from Instrument::AddRegion
619 - when saving, override the gig::Regions sample reference simply by
620 the region's first dimension region's sample (avoids an exception
621 when trying to save a new instrument)
622 - fixed AddDimension() method which did not fill out all mandatory
623 dimension definition fields
624
625 * src/DLS.cpp, src/DLS.h:
626 - added Instrument::MoveRegion method
627 - fixed software info field which was wrongly stored on instruments,
628 causing an exception when trying to save a new instrument
629
630 * src/RIFF.cpp, src/RIFF.h:
631 - fixed RIFF::Chunk destructor which did not unregister previously
632 resized chunks, leading to a "zero size chunk" exception when
633 File::Save() was called
634 - added List::MoveSubChunk method
635

697 - added write support
698 - Chunk::LoadChunkData() can now be called again to resize the buffer
699 after a Chunk::Resize() and before the File::Save() call to allow
700 placing the new data in the chunk's write buffer and perform the
701 resize and write operations in one rush
702
703 * src/gigdump.cpp:
704 - fixed to show the correct amount of dimension regions instead of 32
705 (patch by James Wylder)

758 articulation informations are ignored at the moment
759 (patch by Andreas Persson)
760 - added some file format compatibility checks
761 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
762 never used, because the necessary check was made before

814 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
815 - fixed man pages automake install rule (which didn't work on Mandrake,
816 SuSE and Fedora)
817 - fixed generation of Doxygen API documentation (now also included in
818 RPM and Debian packages)
819
820 * src/gig.cpp, src/gig.h:
821 - fixed / improved accuracy of all three velocity to volume
822 transformation functions a.k.a. 'nonlinear','linear','special'
823 (patch by Andreas Persson)
824 - denormals are filtered from the velocity to volume tables
825 - bugfix for dimension region switching (wrong handling of the release
826 trigger dimension, no bit range check for dimensions of split type

830 - added class attribute 'Layers' to class 'gig::Region'
831 - symbol prototyping of gig::Region (fixes build failure with qsampler)
832

852 - added support for generating Debian packages
853 - version of shared library can be set in configure.in
854
855 Version 0.7.0 (3 May 2004)
856
857 * general changes:
858 - various big endian specific corrections
859 (successfully tested now on PPC)
860 - minor adjustments to avoid compile errors on some systems
861 (using now pow() instead of powl() and --pedantic g++ compiler switch)
862 - libtoolized the library
863 - added man pages for the command line tools
864 (gigextract, gigdump, dlsdump, rifftree)
865
866 * src/gig.cpp, src/gig.h:
867 - fixed bug in decompression algorithm which caused it not to detect
868 the end of a stream
869 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
870 takes the MIDI key velocity value as an argument and returns the
871 appropriate volume factor (0.0 ... 1.0) for the sample to be played
872 back, the velocity curve transformation functions used for this are
873 only an approximation so far
874 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
875 'Sample::LoopSize' which reflected wrong values
876 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
877 measured in sample points instead of byte offset
878 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
879 'Sample::FineTune'
880 - added class attribute 'Sample::LoopSize'
881 - added method GetInstrument(uint index) to class 'File'
882 - added ReadAndLoop() method to class 'Sample' which is an extension to
883 the normal Read() method to honor the sample's looping information
884 while streaming from disk
885 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
886 'eg2_ctrl_t': replaced this huge enumeration by a structure which
887 reflects the MIDI controller number in case of an ordinary control
888 change controller (this saves a huge switch-case block in the
889 application of the library user)
890 - renamed following attributes in class 'DimensionRegion':
891 'AttenuationContol' -> 'AttenuationController',
892 'InvertAttenuationControl' -> 'InvertAttenuationController',
893 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
894 - minor fix in API documentation for method GetVelocityAttenuation() in
895 class 'DimensionRegion'
896
897 * src/RIFF.cpp, src/RIFF.h:
898 - added additional API documentation
899 - minor fix in Chunk::Read() method (only a minor efficiency issue)
900
901 * src/gigdump.cpp:
902 - added printout of samples' looping informations
903
904 Version 0.6.0 (3 Nov 2003)
905
906 * initial release
