89 Version 4.3.0 (9 May 2021)
90
91 * general changes:
92 - Require at least a C++11 compliant compiler.
93 - Require some UUID generating function by underlying system.
94
95 * src/gig.cpp, src/gig.h:
96 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
97 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
98 allow to define override LFOs' wave form (e.g. saw or square instead of
99 the default wave form which was always sine in the original
100 Gigasampler/GigaStudio software).
101 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
102 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
103 move the start point horizontally of the LFOs' waves (0�� ... 360��).
104 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
105 (the original Gigasampler/GigaStudio software only had that flip phase
106 option for LFO1 and LFO2).
107 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
108 Region::UsesAnyGigFormatExtension(),
109 Instrument::UsesAnyGigFormatExtension() and
110 File::UsesAnyGigFormatExtension() (however only as private methods yet,
111 see comments on methods why).
112 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
113 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
114 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
115 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
116 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
117 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
118 (patch by Ivan Maguidhir).
119 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
120 (original patch by Ivan Maguidhir).
121 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
122 dimensions being in different order after deleting a dimension zone.
123 - Script: Generate a persistent UUID for each script.
124 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
125 accordingly added new methods to Instrument class:
126 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
127 GetScriptPatchVariable(), SetScriptPatchVariable(),
128 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
129 as child of our '3LS ' list chunk on Instrument level.
130 - Fixed undefined behaviour when modifying script slots on an instrument
131 that had been cloned and not been saved yet (e.g. unintended modification
132 of original instrument's script slots, and crash on Instrument destruction
133 due to double free of pScriptRefs).
134
135 * src/Serialization.cpp, src/Serialization.h:
136 - Fixed broken Archive(RawData) constructor which always threw an
137 Exception.
138 - Added built-in support for C++ String objects (a.k.a. std::string
139 from the STL) and bumped Srx format version to 1.1 for that reason.
140 - Fixed assertion fault on some systems if a member variable defined was
141 serialized which was declared as size_t or ssize_t data type.
142 - Added new method Archive::operation() which allows applications to
143 distinguish between serialization vs. deserialization in their
144 serialize() method implementations.
145 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
146 the STL).
147 - Member offsets are now signed and for (newly added support of) member
148 variables on the heap -1 is always used as offset instead.
149 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
150 STL).
151 - DataType: Added optional 2nd custom type name.
152 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
153 STL).
154
155 * src/helper.h:
156 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
157 function call.
158
159 * src/tools/gigdump.cpp:
160 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
161 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
162 LFO2FlipPhase and LFO3FlipPhase.
163
164 Version 4.2.0 (25 Jul 2019)
165
166 * general changes:
167 - Added MSVC build support (anonymous patch from mailing list).
168 - Introduced CMake build support (yet constrained for building with MSVC)
169 (anonymous patch from mailing list).
170 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
171 destructors. Added new virtual method DeleteChunks() to those classes
172 for this which must be explicitly called instead to remove their RIFF
173 chunks.
174 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
175 of zero; which is unsafe per se.
176 - Added C++11 "override" keyword where appropriate.
177 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
178 of their actions when not passing a progress_t callback structure.
179
180 * src/gig.cpp, src/gig.h:
181 - Fixed Doxygen API comments for enum types (currently latest Doxygen
182 [v1.8.13] only supports C comments in macro arguments expansion, but
183 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
184 the Doxygen source code, which currently also filter out new line
185 \n chars).
186 - Added new method File::CountSamples().
187 - Added new method File::CountInstruments().
188 - Fixed gig v4 files falsely being handled as v2 format
189 (patch by Ivan Maguidhir).
190 - Added gig v4 version identifier (File::VERSION_4).
191 - GIG FORMAT EXTENSION: Added attribute
192 DimensionRegion::SustainReleaseTrigger which allows to define whether
193 a sustain pedal up event shall cause a release trigger sample to be
194 played (default: don't play release trigger sample by sustain pedal).
195 - GIG FORMAT EXTENSION: Added attribute
196 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
197 regular behaviour of playing release trigger sample on MIDI note-off
198 events.
199 - Introduced support for writing extension files (.gx01, .gx02, ...)
200 (original patch by Ivan Maguidhir).
201 - Many gig classes derive now from DLS::Storage (see DLS changes below).
202 - Added File::GetRiffFile() method.
203
204 * src/DLS.cpp, src/DLS.h:
205 - File: Fixed implicitly allocated RIFF::File object never been freed.
206 - Added new abstract interface base class DLS::Storage which is derived by
207 the respective classes for implementing (the old) UpdateChunks() and the
208 new DeleteChunks() method.
209 - Added File::GetRiffFile() method.
210
211 * src/sf2.cpp, src/sf2.h:
212 - Added Sample::GetFile() method.
213 - Added File::GetRiffFile() method.
214
215 * src/Serialization.cpp, src/Serialization.h:
216 - Hide pure internal declarations from header file to avoid numerous
217 compiler warnings when building and linking against the public API.
218 - Fixed comparision logic bug
219 - Fixed memory leak in DataType::customTypeName().
220
221 * src/RIFF.cpp, src/RIFF.h:
222 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
223 caused a resource leak
224 - Avoid compiler warning when building for 32 bit windows.
225 - Added new method progress_t::subdivide().
226 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
227 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
228 allows a more fine graded control into which portions the subtasks are
229 divided to.
230
231 * src/tools/gigdump.cpp:
232 - Added command line option --instrument-names which causes only
233 instrument names and their index numbers to be printed.
234
235 Version 4.1.0 (25 Nov 2017)
236 * general changes:
237 - removed 2 GB limitation when loading a gig or DLS file
238 - using now native integer size where appropriate
239 - fixed minor issues with man pages (patch by Debian maintainer)
240 - fixed various spelling mistakes (patch by Debian maintainer)
241 - Added new "Serialization" framework (and equally named namespace)
242 which allows to serialize and deserialize native C++ objects
243 in a portable, easy and flexible way.
244 - print compiler warning if no RTTI available
245 - Fixed potential crash in command line tools gig2stereo, korg2gig,
246 korgdump and sf2extract.
247 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
248 (original patch by Paul Brossier, slightly modified).
249 - Debian: Fixed packaging error about invalid substitution variable
250 "Source-Version".
251 - Raised Debian compatibility level to Debian 9 "Stretch".
252
253 * src/gig.cpp, src/gig.h:
254 - fixed bug in Script::SetGroup: the script chunk wasn't moved
255 - fixed compilation error with clang 3.4
256 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
257 as one single monolithic gig file. In case .gig file is >= 2GB expect a
258 large monolithic file, otherwise if .gig file is < 2 GB check for
259 "extension" files (.gx01, .gx02, ...) instead.
260 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
261 if there were dimensions after the velocity dimension: it only created
262 valid velocity tables for cases of dimensions lower than the velocity
263 dimension.
264 - added new method Sample::VerifyWaveData() which allows to check whether
265 a sample had been damaged for some reason
266 - Fix: samples' CRC checksums were damaged on file structure changes.
267 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
268 - Added new method Sample::GetWaveDataCRC32Checksum().

273 of passed original file.
274 - Added support for serializing & deserializing DimensionRegion
275 objects (and crossfade_t and leverage_ctrl_t objects).
276 - Added enum reflection API functions for retrieving enum declaration type
277 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
278 - Exception class now has a variadic constructor which allows to add
279 textual format specifiers like with printf().
280 - On unknown leverage controller exception: show precise unknown leverage
281 controller number found.
282 - Ignore invalid leverage controller types and just show a warning on the
283 console instead of throwing an exception.
284 - Added new struct eg_opt_t and new class member variable
285 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
286 extension to the gig file format, which allows to override the default
287 behavior of the first two EGs' state machines.
288 - Fixed undefined behavior when loading a gig file with invalid
289 velocity curve parameters (fixes CVE-2017-12951).
290 - Fixed undefined behavior when loading a gig file with invalid wave
291 pool index number (fixes CVE-2017-12954).
292
293 * src/DLS.cpp, src/DLS.h:
294 - Sample: wave pool offsets are now 64 bits (to allow support for files
295 larger than 4 GB).
296 - Exception class now has a variadic constructor which allows to add
297 textual format specifiers like with printf().
298
299 * src/RIFF.cpp, src/RIFF.h:
300 - added support for RIFF files larger than 4 GB, by default the required
301 internal RIFF file offset size is automatically detected (that is RIFF
302 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
303 automatically use 64 bit offsets), a particular offset size can be forced
304 with a new option added to the RIFF File constructor though
305 - when saving a modified, grown RIFF file, the temporary file size during
306 Save() operation will no longer be larger than the final grown file size
307 - Exception class now has a variadic constructor which allows to add
308 textual format specifiers like with printf().
309
310 * src/Serialization.cpp, src/Serialization.h:
311 - Archive: Added method isModified().
312 - Archive: Added method setAutoValue().
313 - Archive: Added method setIntValue().
314 - Archive: Added method setRealValue().
315 - Archive: Added method setBoolValue().
316 - Archive: Added method setEnumValue().
317 - Archive: Added method valueAsString().
318 - Archive::rawData(): Automatically re-encode new raw data stream if
319 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
320 - Object: Added method memberByUID().
321 - Object: remove() method is now protected.
322 - Archive: Added method removeMember().
323 - Archive: Added methods name() and setName().
324 - Archive: Added methods comment() and setComment().
325 - Archive: Added methods timeStampCreated(), timeStampModified(),
326 dateTimeCreated() and dateTimeModified().
327 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
328 - DataType: Implemented demangling C++ type names (for methods
329 asLongDescr() and customTypeName(bool demangle=false)).
330 - Archive::setAutoValue(): Handle human readable boolean text
331 representations like "yes", "no", "true", "false" as expected.
332 - Exception class now has a variadic constructor which allows to add
333 textual format specifiers like with printf().
334 - DataType fix: Retain backward compatibility to older versions of native
335 C++ classes/structs.
336

352 data
353 - added and implemented new parameter "--verify" which allows to check
354 the raw wave form data integrity of all samples
355 - added and implemented new parameter "--rebuild-checksums" which allows
356 to recalculate the CRC32 checksum of all samples' raw wave data and
357 rebuilding the gig file's global checksum table (i.e. in case the
358 file's checksum table was damaged)
359 - print samples' CRC32 checksums
360 - Print the new EG behavior options (eg_opt_t).
361
362 * src/tools/gigextract.cpp:
363 - Fix: if sample name contains a path separator (slash or backslash) then
364 replace them by a minus sign to avoid file system issues.
365
366 * src/tools/gig2stereo.cpp:
367 - Also merge mono sample pairs with non matching loop information if
368 argument --incompatible was given.
369

407
408 * AKAI file format:
409 - Added Linux/POSIX ported version of libakai. Note that libakai is released

475 - added new method File::SetFileName() allowing to call File::Save()
476 later on without passing a file name
477 - added new method File::IsNew()
478 - added support for loading RIFF-like files with a bit different layout
479 than "real" RIFF files (used for KORG format support)
480 - added new method Chunk::GetFile()
481 - added new method Chunk::GetLayout()
482 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
483 allows to move a subchunk within the current List, whereas the new 2nd
484 one allows to move the subchunk from the current list to another list
485 - POSIX: only assume -1 result value as error on open() calls
486 - POSIX: show operating system's error reason if opening a file failed
487 - Added support for custom progress notification while saving to RIFF file.
488 - Fixed embarrassing old bug: POSIX read() errors were never detected on
489 Chunk::Read() calls due to signment incompatible variable.
490 - Cleanup of an old DLL binary backward compatibility hack.
491
492 * src/gigextract.cpp:
493 - export sample loop, unity note and fine tune with libsndfile
494
495 * src/riftree.cpp:
496 - added more command line options for being able to also dump other kind
497 of file formats similar but not equal to the RIFF format

511 sample start before trying to (re)load sample data from file (#82)
512 - bugfix: EG3 depth parameter was not saved correctly
513 - fixed crash which occured when streaming a gig sample with
514 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
515
516 * src/RIFF.cpp, src/RIFF.h:
517 - bugfix: saving to the same file after the file size had been
518 increased made the file corrupt (#82)
519 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
520 is not written physically yet (#82)
521 - bugfix: saving to the same file after the file size had been
522 decreased sometimes also made the file corrupt!
523 - bugfix: undefined behavior (e.g. endless loop) when opening zero
524 length files, now throws a RIFF::Exception instead (fixes bug #121)
525 - bugfix: destructor for base class RIFF::Chunk accessed members
526 of derived class RIFF::File, which is bad, and caused crashes
527 when using Visual C++
528 - bugfix: files that contain zero length RIFF lists were not read
529 correctly (fixes #127) (bug was introduced 2009-03-13)

571 instrument constructors
572 - clear unused fields when saving samples and regions
573 - fixed write support bugs: v3 dimension limits and chunksize

592 v3 dimension limits were not correctly initialized and saved
593 when dimensions were added or deleted, v3 wave pool offsets were
594 not saved correctly
595 - write support: 24 bit samples can now be written
596 - write support: version 3 is now the default for new files
597 - more write support fixes: the 3ewg chunk is now bigger for v3,

599 list in v3 files now always has 128 entries, several parameters
600 where incorrectly saved due to an operator precedence mistake
601 - DeleteSample now removes all references to the deleted sample
602 - AddDimension now copies all parameters from existing dimension
603 regions and also makes sure that the samplechannel dimension is
604 placed first in the list of dimensions.
605 - added method GetParent() to class 'DimensionRegion', which returns its
606 parent Region
607 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
608 unused areas
609 - added various setter methods to DimensionRegion class which take care
610 of updating lookup tables / caches.

628 - added support for custom splits points for other dimensions than
629 velocity (gig v3 feature)
630 - added "smart midi" and "round robin keyboard" dimensions
631 - added new method File::DeleteGroupOnly() which only deletes the given
632 group but moves all its members to another group, the other method,
633 that is File::DeleteGroup() now removes not just the group, but also
634 all the samples that belong to that group
635 - fixed crash which occured on interfering File::DeleteSample() and
636 File::GetNextSample() calls (due to iterator invalidation)

638 - fixed group destructor which did not remove the RIFF chunk associated
639 with the group
640 - added Instrument::MoveRegion method
641 - fixed constructor for Region, which did not initialize correctly
642 when used from Instrument::AddRegion
643 - when saving, override the gig::Regions sample reference simply by
644 the region's first dimension region's sample (avoids an exception
645 when trying to save a new instrument)
646 - fixed AddDimension() method which did not fill out all mandatory
647 dimension definition fields
648
649 * src/DLS.cpp, src/DLS.h:

783 (patch by Andreas Persson)
784 - added some file format compatibility checks
785 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

840 SuSE and Fedora)
841 - fixed generation of Doxygen API documentation (now also included in
842 RPM and Debian packages)
843
844 * src/gig.cpp, src/gig.h:
845 - fixed / improved accuracy of all three velocity to volume
846 transformation functions a.k.a. 'nonlinear','linear','special'
847 (patch by Andreas Persson)
848 - denormals are filtered from the velocity to volume tables
849 - bugfix for dimension region switching (wrong handling of the release
850 trigger dimension, no bit range check for dimensions of split type

854 - added class attribute 'Layers' to class 'gig::Region'
855 - symbol prototyping of gig::Region (fixes build failure with qsampler)
856

887 - added man pages for the command line tools
888 (gigextract, gigdump, dlsdump, rifftree)
889
890 * src/gig.cpp, src/gig.h:
891 - fixed bug in decompression algorithm which caused it not to detect
892 the end of a stream
893 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
894 takes the MIDI key velocity value as an argument and returns the
895 appropriate volume factor (0.0 ... 1.0) for the sample to be played
896 back, the velocity curve transformation functions used for this are
897 only an approximation so far
898 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
899 'Sample::LoopSize' which reflected wrong values
900 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
901 measured in sample points instead of byte offset
902 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
903 'Sample::FineTune'
904 - added class attribute 'Sample::LoopSize'
905 - added method GetInstrument(uint index) to class 'File'
906 - added ReadAndLoop() method to class 'Sample' which is an extension to
907 the normal Read() method to honor the sample's looping information
908 while streaming from disk
909 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
910 'eg2_ctrl_t': replaced this huge enumeration by a structure which
911 reflects the MIDI controller number in case of an ordinary control
912 change controller (this saves a huge switch-case block in the
913 application of the library user)
914 - renamed following attributes in class 'DimensionRegion':
915 'AttenuationContol' -> 'AttenuationController',
916 'InvertAttenuationControl' -> 'InvertAttenuationController',
917 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
918 - minor fix in API documentation for method GetVelocityAttenuation() in
919 class 'DimensionRegion'
920
921 * src/RIFF.cpp, src/RIFF.h:
922 - added additional API documentation
923 - minor fix in Chunk::Read() method (only a minor efficiency issue)
924
925 * src/gigdump.cpp:
926 - added printout of samples' looping informations
927
928 Version 0.6.0 (3 Nov 2003)
