87 Version 4.3.0 (9 May 2021)
88
89 * general changes:
90 - Require at least a C++11 compliant compiler.
91 - Require some UUID generating function by underlying system.
92
93 * src/gig.cpp, src/gig.h:
94 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
95 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
96 allow to define override LFOs' wave form (e.g. saw or square instead of
97 the default wave form which was always sine in the original
98 Gigasampler/GigaStudio software).
99 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
100 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
101 move the start point horizontally of the LFOs' waves (0�� ... 360��).
102 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
103 (the original Gigasampler/GigaStudio software only had that flip phase
104 option for LFO1 and LFO2).
105 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
106 Region::UsesAnyGigFormatExtension(),
107 Instrument::UsesAnyGigFormatExtension() and
108 File::UsesAnyGigFormatExtension() (however only as private methods yet,
109 see comments on methods why).
110 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
111 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
112 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
113 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
114 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
115 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
116 (patch by Ivan Maguidhir).
117 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
118 (original patch by Ivan Maguidhir).
119 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
120 dimensions being in different order after deleting a dimension zone.
121 - Script: Generate a persistent UUID for each script.
122 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
123 accordingly added new methods to Instrument class:
124 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
125 GetScriptPatchVariable(), SetScriptPatchVariable(),
126 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
127 as child of our '3LS ' list chunk on Instrument level.
128 - Fixed undefined behaviour when modifying script slots on an instrument
129 that had been cloned and not been saved yet (e.g. unintended modification
130 of original instrument's script slots, and crash on Instrument destruction
131 due to double free of pScriptRefs).
132
133 * src/Serialization.cpp, src/Serialization.h:
134 - Fixed broken Archive(RawData) constructor which always threw an
135 Exception.
136 - Added built-in support for C++ String objects (a.k.a. std::string
137 from the STL) and bumped Srx format version to 1.1 for that reason.
138 - Fixed assertion fault on some systems if a member variable defined was
139 serialized which was declared as size_t or ssize_t data type.
140 - Added new method Archive::operation() which allows applications to
141 distinguish between serialization vs. deserialization in their
142 serialize() method implementations.
143 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
144 the STL).
145 - Member offsets are now signed and for (newly added support of) member
146 variables on the heap -1 is always used as offset instead.
147 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
148 STL).
149 - DataType: Added optional 2nd custom type name.
150 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
151 STL).
152
153 * src/helper.h:
154 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
155 function call.
156
157 * src/tools/gigdump.cpp:
158 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
159 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
160 LFO2FlipPhase and LFO3FlipPhase.
161
162 Version 4.2.0 (25 Jul 2019)
163
164 * general changes:
165 - Added MSVC build support (anonymous patch from mailing list).
166 - Introduced CMake build support (yet constrained for building with MSVC)
167 (anonymous patch from mailing list).
168 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
169 destructors. Added new virtual method DeleteChunks() to those classes
170 for this which must be explicitly called instead to remove their RIFF
171 chunks.
172 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
173 of zero; which is unsafe per se.
174 - Added C++11 "override" keyword where appropriate.
175 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
176 of their actions when not passing a progress_t callback structure.
177
178 * src/gig.cpp, src/gig.h:
179 - Fixed Doxygen API comments for enum types (currently latest Doxygen
180 [v1.8.13] only supports C comments in macro arguments expansion, but
181 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
182 the Doxygen source code, which currently also filter out new line
183 \n chars).
184 - Added new method File::CountSamples().
185 - Added new method File::CountInstruments().
186 - Fixed gig v4 files falsely being handled as v2 format
187 (patch by Ivan Maguidhir).
188 - Added gig v4 version identifier (File::VERSION_4).
189 - GIG FORMAT EXTENSION: Added attribute
190 DimensionRegion::SustainReleaseTrigger which allows to define whether
191 a sustain pedal up event shall cause a release trigger sample to be
192 played (default: don't play release trigger sample by sustain pedal).
193 - GIG FORMAT EXTENSION: Added attribute
194 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
195 regular behaviour of playing release trigger sample on MIDI note-off
196 events.
197 - Introduced support for writing extension files (.gx01, .gx02, ...)
198 (original patch by Ivan Maguidhir).
199 - Many gig classes derive now from DLS::Storage (see DLS changes below).
200 - Added File::GetRiffFile() method.
201
202 * src/DLS.cpp, src/DLS.h:
203 - File: Fixed implicitly allocated RIFF::File object never been freed.
204 - Added new abstract interface base class DLS::Storage which is derived by
205 the respective classes for implementing (the old) UpdateChunks() and the
206 new DeleteChunks() method.
207 - Added File::GetRiffFile() method.
208
209 * src/sf2.cpp, src/sf2.h:
210 - Added Sample::GetFile() method.
211 - Added File::GetRiffFile() method.
212
213 * src/Serialization.cpp, src/Serialization.h:
214 - Hide pure internal declarations from header file to avoid numerous
215 compiler warnings when building and linking against the public API.
216 - Fixed comparision logic bug
217 - Fixed memory leak in DataType::customTypeName().
218
219 * src/RIFF.cpp, src/RIFF.h:
220 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
221 caused a resource leak
222 - Avoid compiler warning when building for 32 bit windows.
223 - Added new method progress_t::subdivide().
224 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
225 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
226 allows a more fine graded control into which portions the subtasks are
227 divided to.
228
229 * src/tools/gigdump.cpp:
230 - Added command line option --instrument-names which causes only
231 instrument names and their index numbers to be printed.
232
233 Version 4.1.0 (25 Nov 2017)
234 * general changes:
235 - removed 2 GB limitation when loading a gig or DLS file
236 - using now native integer size where appropriate
237 - fixed minor issues with man pages (patch by Debian maintainer)
238 - fixed various spelling mistakes (patch by Debian maintainer)
239 - Added new "Serialization" framework (and equally named namespace)
240 which allows to serialize and deserialize native C++ objects
241 in a portable, easy and flexible way.
242 - print compiler warning if no RTTI available
243 - Fixed potential crash in command line tools gig2stereo, korg2gig,
244 korgdump and sf2extract.
245 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
246 (original patch by Paul Brossier, slightly modified).
247 - Debian: Fixed packaging error about invalid substitution variable
248 "Source-Version".
249 - Raised Debian compatibility level to Debian 9 "Stretch".
250
251 * src/gig.cpp, src/gig.h:
252 - fixed bug in Script::SetGroup: the script chunk wasn't moved
253 - fixed compilation error with clang 3.4
254 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
255 as one single monolithic gig file. In case .gig file is >= 2GB expect a
256 large monolithic file, otherwise if .gig file is < 2 GB check for
257 "extension" files (.gx01, .gx02, ...) instead.
258 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
259 if there were dimensions after the velocity dimension: it only created
260 valid velocity tables for cases of dimensions lower than the velocity
261 dimension.
262 - added new method Sample::VerifyWaveData() which allows to check whether
263 a sample had been damaged for some reason
264 - Fix: samples' CRC checksums were damaged on file structure changes.
265 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
266 - Added new method Sample::GetWaveDataCRC32Checksum().
267 - Changed default value of EG2Release (filter release time) to 60s.
268 - Instruments' default pitch bend range is now +-2 semi tones.
269 - Fixed CRC checksums being wrong sometimes.
270 - Fix: method File::AddContentOf() did not clone script groups and scripts
271 of passed original file.
272 - Added support for serializing & deserializing DimensionRegion
273 objects (and crossfade_t and leverage_ctrl_t objects).
274 - Added enum reflection API functions for retrieving enum declaration type
275 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
276 - Exception class now has a variadic constructor which allows to add
277 textual format specifiers like with printf().
278 - On unknown leverage controller exception: show precise unknown leverage
279 controller number found.
280 - Ignore invalid leverage controller types and just show a warning on the
281 console instead of throwing an exception.
282 - Added new struct eg_opt_t and new class member variable
283 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
284 extension to the gig file format, which allows to override the default
285 behavior of the first two EGs' state machines.
286 - Fixed undefined behavior when loading a gig file with invalid
287 velocity curve parameters (fixes CVE-2017-12951).
288 - Fixed undefined behavior when loading a gig file with invalid wave
289 pool index number (fixes CVE-2017-12954).
290
291 * src/DLS.cpp, src/DLS.h:
292 - Sample: wave pool offsets are now 64 bits (to allow support for files
293 larger than 4 GB).
294 - Exception class now has a variadic constructor which allows to add
295 textual format specifiers like with printf().
296
297 * src/RIFF.cpp, src/RIFF.h:
298 - added support for RIFF files larger than 4 GB, by default the required
299 internal RIFF file offset size is automatically detected (that is RIFF
300 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
301 automatically use 64 bit offsets), a particular offset size can be forced
302 with a new option added to the RIFF File constructor though
303 - when saving a modified, grown RIFF file, the temporary file size during
304 Save() operation will no longer be larger than the final grown file size
305 - Exception class now has a variadic constructor which allows to add
306 textual format specifiers like with printf().
307
308 * src/Serialization.cpp, src/Serialization.h:
309 - Archive: Added method isModified().
310 - Archive: Added method setAutoValue().
311 - Archive: Added method setIntValue().
312 - Archive: Added method setRealValue().
313 - Archive: Added method setBoolValue().
314 - Archive: Added method setEnumValue().
315 - Archive: Added method valueAsString().
316 - Archive::rawData(): Automatically re-encode new raw data stream if
317 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
318 - Object: Added method memberByUID().
319 - Object: remove() method is now protected.
320 - Archive: Added method removeMember().
321 - Archive: Added methods name() and setName().
322 - Archive: Added methods comment() and setComment().
323 - Archive: Added methods timeStampCreated(), timeStampModified(),
324 dateTimeCreated() and dateTimeModified().
325 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
326 - DataType: Implemented demangling C++ type names (for methods
327 asLongDescr() and customTypeName(bool demangle=false)).
328 - Archive::setAutoValue(): Handle human readable boolean text
329 representations like "yes", "no", "true", "false" as expected.
330 - Exception class now has a variadic constructor which allows to add
331 textual format specifiers like with printf().
332 - DataType fix: Retain backward compatibility to older versions of native
333 C++ classes/structs.
334
335 * src/Akai.cpp:
336 - Fixed compilation error with recent, more strict compilers.

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

405
406 * AKAI file format:
407 - Added Linux/POSIX ported version of libakai. Note that libakai is released

483 - POSIX: only assume -1 result value as error on open() calls
484 - POSIX: show operating system's error reason if opening a file failed
485 - Added support for custom progress notification while saving to RIFF file.
486 - Fixed embarrassing old bug: POSIX read() errors were never detected on
487 Chunk::Read() calls due to signment incompatible variable.
488 - Cleanup of an old DLL binary backward compatibility hack.
489
490 * src/gigextract.cpp:
491 - export sample loop, unity note and fine tune with libsndfile

517 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
518 is not written physically yet (#82)
519 - bugfix: saving to the same file after the file size had been
520 decreased sometimes also made the file corrupt!
521 - bugfix: undefined behavior (e.g. endless loop) when opening zero
522 length files, now throws a RIFF::Exception instead (fixes bug #121)
523 - bugfix: destructor for base class RIFF::Chunk accessed members
524 of derived class RIFF::File, which is bad, and caused crashes
525 when using Visual C++
526 - bugfix: files that contain zero length RIFF lists were not read
527 correctly (fixes #127) (bug was introduced 2009-03-13)

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

586 instruments
587 - write support: improved the default values for dimension region
588 parameters
589 - more write support fixes: crossfade parameters were not saved,
590 v3 dimension limits were not correctly initialized and saved
591 when dimensions were added or deleted, v3 wave pool offsets were
592 not saved correctly
593 - write support: 24 bit samples can now be written
594 - write support: version 3 is now the default for new files
595 - more write support fixes: the 3ewg chunk is now bigger for v3,

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

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

637 with the group
638 - added Instrument::MoveRegion method
639 - fixed constructor for Region, which did not initialize correctly
640 when used from Instrument::AddRegion
641 - when saving, override the gig::Regions sample reference simply by
642 the region's first dimension region's sample (avoids an exception
643 when trying to save a new instrument)

645 dimension definition fields
646
647 * src/DLS.cpp, src/DLS.h:

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

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

878
879 * general changes:
880 - various big endian specific corrections

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