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

279 of passed original file.
280 - Added support for serializing & deserializing DimensionRegion
281 objects (and crossfade_t and leverage_ctrl_t objects).
282 - Added enum reflection API functions for retrieving enum declaration type
283 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
284 - Exception class now has a variadic constructor which allows to add
285 textual format specifiers like with printf().
286 - On unknown leverage controller exception: show precise unknown leverage
287 controller number found.
288 - Ignore invalid leverage controller types and just show a warning on the
289 console instead of throwing an exception.
290 - Added new struct eg_opt_t and new class member variable
291 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
292 extension to the gig file format, which allows to override the default
293 behavior of the first two EGs' state machines.
294 - Fixed undefined behavior when loading a gig file with invalid
295 velocity curve parameters (fixes CVE-2017-12951).
296 - Fixed undefined behavior when loading a gig file with invalid wave
297 pool index number (fixes CVE-2017-12954).
298
299 * src/DLS.cpp, src/DLS.h:
300 - Sample: wave pool offsets are now 64 bits (to allow support for files
301 larger than 4 GB).
302 - Exception class now has a variadic constructor which allows to add
303 textual format specifiers like with printf().
304
305 * src/RIFF.cpp, src/RIFF.h:
306 - added support for RIFF files larger than 4 GB, by default the required
307 internal RIFF file offset size is automatically detected (that is RIFF
308 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
309 automatically use 64 bit offsets), a particular offset size can be forced
310 with a new option added to the RIFF File constructor though
311 - when saving a modified, grown RIFF file, the temporary file size during
312 Save() operation will no longer be larger than the final grown file size
313 - Exception class now has a variadic constructor which allows to add
314 textual format specifiers like with printf().
315
316 * src/Serialization.cpp, src/Serialization.h:
317 - Archive: Added method isModified().
318 - Archive: Added method setAutoValue().
319 - Archive: Added method setIntValue().
320 - Archive: Added method setRealValue().
321 - Archive: Added method setBoolValue().
322 - Archive: Added method setEnumValue().
323 - Archive: Added method valueAsString().
324 - Archive::rawData(): Automatically re-encode new raw data stream if
325 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
326 - Object: Added method memberByUID().
327 - Object: remove() method is now protected.
328 - Archive: Added method removeMember().
329 - Archive: Added methods name() and setName().
330 - Archive: Added methods comment() and setComment().
331 - Archive: Added methods timeStampCreated(), timeStampModified(),
332 dateTimeCreated() and dateTimeModified().
333 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
334 - DataType: Implemented demangling C++ type names (for methods
335 asLongDescr() and customTypeName(bool demangle=false)).
336 - Archive::setAutoValue(): Handle human readable boolean text
337 representations like "yes", "no", "true", "false" as expected.
338 - Exception class now has a variadic constructor which allows to add
339 textual format specifiers like with printf().
340 - DataType fix: Retain backward compatibility to older versions of native
341 C++ classes/structs.
342
343 * src/Akai.cpp:
344 - Fixed compilation error with recent, more strict compilers.

358 data
359 - added and implemented new parameter "--verify" which allows to check
360 the raw wave form data integrity of all samples
361 - added and implemented new parameter "--rebuild-checksums" which allows
362 to recalculate the CRC32 checksum of all samples' raw wave data and
363 rebuilding the gig file's global checksum table (i.e. in case the
364 file's checksum table was damaged)
365 - print samples' CRC32 checksums
366 - Print the new EG behavior options (eg_opt_t).
367
368 * src/tools/gigextract.cpp:
369 - Fix: if sample name contains a path separator (slash or backslash) then
370 replace them by a minus sign to avoid file system issues.
371
372 * src/tools/gig2stereo.cpp:
373 - Also merge mono sample pairs with non matching loop information if
374 argument --incompatible was given.

473 - added new method Sample::ReadNoClear()
474
475 * src/RIFF.cpp, src/RIFF.h:

495 Chunk::Read() calls due to signment incompatible variable.
496 - Cleanup of an old DLL binary backward compatibility hack.
497
498 * src/gigextract.cpp:
499 - export sample loop, unity note and fine tune with libsndfile

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

577 instrument constructors
578 - clear unused fields when saving samples and regions
579 - fixed write support bugs: v3 dimension limits and chunksize

594 instruments
595 - write support: improved the default values for dimension region
596 parameters
597 - more write support fixes: crossfade parameters were not saved,
598 v3 dimension limits were not correctly initialized and saved
599 when dimensions were added or deleted, v3 wave pool offsets were
600 not saved correctly
601 - write support: 24 bit samples can now be written
602 - write support: version 3 is now the default for new files
603 - more write support fixes: the 3ewg chunk is now bigger for v3,

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

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

645 with the group
646 - added Instrument::MoveRegion method
647 - fixed constructor for Region, which did not initialize correctly
648 when used from Instrument::AddRegion
649 - when saving, override the gig::Regions sample reference simply by
650 the region's first dimension region's sample (avoids an exception
651 when trying to save a new instrument)

789 (patch by Andreas Persson)
790 - added some file format compatibility checks
791 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

860 - added class attribute 'Layers' to class 'gig::Region'
861 - symbol prototyping of gig::Region (fixes build failure with qsampler)
862

886
887 * general changes:
888 - various big endian specific corrections

893 - added man pages for the command line tools
894 (gigextract, gigdump, dlsdump, rifftree)
895
896 * src/gig.cpp, src/gig.h:
897 - fixed bug in decompression algorithm which caused it not to detect
898 the end of a stream
899 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
900 takes the MIDI key velocity value as an argument and returns the
901 appropriate volume factor (0.0 ... 1.0) for the sample to be played
902 back, the velocity curve transformation functions used for this are
903 only an approximation so far
904 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
905 'Sample::LoopSize' which reflected wrong values
906 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
907 measured in sample points instead of byte offset
908 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
909 'Sample::FineTune'
910 - added class attribute 'Sample::LoopSize'
911 - added method GetInstrument(uint index) to class 'File'
912 - added ReadAndLoop() method to class 'Sample' which is an extension to
913 the normal Read() method to honor the sample's looping information
914 while streaming from disk
915 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
916 'eg2_ctrl_t': replaced this huge enumeration by a structure which
917 reflects the MIDI controller number in case of an ordinary control
918 change controller (this saves a huge switch-case block in the
919 application of the library user)
920 - renamed following attributes in class 'DimensionRegion':
921 'AttenuationContol' -> 'AttenuationController',
922 'InvertAttenuationControl' -> 'InvertAttenuationController',
923 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
924 - minor fix in API documentation for method GetVelocityAttenuation() in
925 class 'DimensionRegion'
926
927 * src/RIFF.cpp, src/RIFF.h:
928 - added additional API documentation
929 - minor fix in Chunk::Read() method (only a minor efficiency issue)
930
931 * src/gigdump.cpp:
932 - added printout of samples' looping informations
933
934 Version 0.6.0 (3 Nov 2003)
