117 Version 4.3.0 (9 May 2021)
118
119 * general changes:
120 - Require at least a C++11 compliant compiler.
121 - Require some UUID generating function by underlying system.
122
123 * src/gig.cpp, src/gig.h:
124 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
125 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
126 allow to define override LFOs' wave form (e.g. saw or square instead of
127 the default wave form which was always sine in the original
128 Gigasampler/GigaStudio software).
129 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
130 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
131 move the start point horizontally of the LFOs' waves (0�� ... 360��).
132 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
133 (the original Gigasampler/GigaStudio software only had that flip phase
134 option for LFO1 and LFO2).
135 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
136 Region::UsesAnyGigFormatExtension(),
137 Instrument::UsesAnyGigFormatExtension() and
138 File::UsesAnyGigFormatExtension() (however only as private methods yet,
139 see comments on methods why).
140 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
141 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
142 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
143 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
144 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
145 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
146 (patch by Ivan Maguidhir).
147 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
148 (original patch by Ivan Maguidhir).
149 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
150 dimensions being in different order after deleting a dimension zone.
151 - Script: Generate a persistent UUID for each script.
152 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
153 accordingly added new methods to Instrument class:
154 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
155 GetScriptPatchVariable(), SetScriptPatchVariable(),
156 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
157 as child of our '3LS ' list chunk on Instrument level.
158 - Fixed undefined behaviour when modifying script slots on an instrument
159 that had been cloned and not been saved yet (e.g. unintended modification
160 of original instrument's script slots, and crash on Instrument destruction
161 due to double free of pScriptRefs).
162
163 * src/Serialization.cpp, src/Serialization.h:
164 - Fixed broken Archive(RawData) constructor which always threw an
165 Exception.
166 - Added built-in support for C++ String objects (a.k.a. std::string
167 from the STL) and bumped Srx format version to 1.1 for that reason.
168 - Fixed assertion fault on some systems if a member variable defined was
169 serialized which was declared as size_t or ssize_t data type.
170 - Added new method Archive::operation() which allows applications to
171 distinguish between serialization vs. deserialization in their
172 serialize() method implementations.
173 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
174 the STL).
175 - Member offsets are now signed and for (newly added support of) member
176 variables on the heap -1 is always used as offset instead.
177 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
178 STL).
179 - DataType: Added optional 2nd custom type name.
180 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
181 STL).
182
183 * src/helper.h:
184 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
185 function call.
186
187 * src/tools/gigdump.cpp:
188 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
189 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
190 LFO2FlipPhase and LFO3FlipPhase.
191
192 Version 4.2.0 (25 Jul 2019)
193
194 * general changes:
195 - Added MSVC build support (anonymous patch from mailing list).
196 - Introduced CMake build support (yet constrained for building with MSVC)
197 (anonymous patch from mailing list).
198 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
199 destructors. Added new virtual method DeleteChunks() to those classes
200 for this which must be explicitly called instead to remove their RIFF
201 chunks.
202 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
203 of zero; which is unsafe per se.
204 - Added C++11 "override" keyword where appropriate.
205 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
206 of their actions when not passing a progress_t callback structure.
207
208 * src/gig.cpp, src/gig.h:
209 - Fixed Doxygen API comments for enum types (currently latest Doxygen
210 [v1.8.13] only supports C comments in macro arguments expansion, but
211 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
212 the Doxygen source code, which currently also filter out new line
213 \n chars).
214 - Added new method File::CountSamples().
215 - Added new method File::CountInstruments().
216 - Fixed gig v4 files falsely being handled as v2 format
217 (patch by Ivan Maguidhir).
218 - Added gig v4 version identifier (File::VERSION_4).
219 - GIG FORMAT EXTENSION: Added attribute
220 DimensionRegion::SustainReleaseTrigger which allows to define whether
221 a sustain pedal up event shall cause a release trigger sample to be
222 played (default: don't play release trigger sample by sustain pedal).
223 - GIG FORMAT EXTENSION: Added attribute
224 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
225 regular behaviour of playing release trigger sample on MIDI note-off
226 events.
227 - Introduced support for writing extension files (.gx01, .gx02, ...)
228 (original patch by Ivan Maguidhir).
229 - Many gig classes derive now from DLS::Storage (see DLS changes below).
230 - Added File::GetRiffFile() method.
231
232 * src/DLS.cpp, src/DLS.h:
233 - File: Fixed implicitly allocated RIFF::File object never been freed.
234 - Added new abstract interface base class DLS::Storage which is derived by
235 the respective classes for implementing (the old) UpdateChunks() and the
236 new DeleteChunks() method.
237 - Added File::GetRiffFile() method.
238
239 * src/sf2.cpp, src/sf2.h:
240 - Added Sample::GetFile() method.
241 - Added File::GetRiffFile() method.
242
243 * src/Serialization.cpp, src/Serialization.h:
244 - Hide pure internal declarations from header file to avoid numerous
245 compiler warnings when building and linking against the public API.
246 - Fixed comparision logic bug
247 - Fixed memory leak in DataType::customTypeName().
248
249 * src/RIFF.cpp, src/RIFF.h:
250 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
251 caused a resource leak
252 - Avoid compiler warning when building for 32 bit windows.
253 - Added new method progress_t::subdivide().
254 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
255 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
256 allows a more fine graded control into which portions the subtasks are
257 divided to.
258
259 * src/tools/gigdump.cpp:
260 - Added command line option --instrument-names which causes only
261 instrument names and their index numbers to be printed.
262
263 Version 4.1.0 (25 Nov 2017)
264 * general changes:
265 - removed 2 GB limitation when loading a gig or DLS file
266 - using now native integer size where appropriate
267 - fixed minor issues with man pages (patch by Debian maintainer)
268 - fixed various spelling mistakes (patch by Debian maintainer)
269 - Added new "Serialization" framework (and equally named namespace)
270 which allows to serialize and deserialize native C++ objects
271 in a portable, easy and flexible way.
272 - print compiler warning if no RTTI available
273 - Fixed potential crash in command line tools gig2stereo, korg2gig,
274 korgdump and sf2extract.
275 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
276 (original patch by Paul Brossier, slightly modified).
277 - Debian: Fixed packaging error about invalid substitution variable
278 "Source-Version".
279 - Raised Debian compatibility level to Debian 9 "Stretch".
280
281 * src/gig.cpp, src/gig.h:
282 - fixed bug in Script::SetGroup: the script chunk wasn't moved
283 - fixed compilation error with clang 3.4
284 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
285 as one single monolithic gig file. In case .gig file is >= 2GB expect a
286 large monolithic file, otherwise if .gig file is < 2 GB check for
287 "extension" files (.gx01, .gx02, ...) instead.
288 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
289 if there were dimensions after the velocity dimension: it only created
290 valid velocity tables for cases of dimensions lower than the velocity
291 dimension.
292 - added new method Sample::VerifyWaveData() which allows to check whether
293 a sample had been damaged for some reason
294 - Fix: samples' CRC checksums were damaged on file structure changes.
295 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
296 - Added new method Sample::GetWaveDataCRC32Checksum().
297 - Changed default value of EG2Release (filter release time) to 60s.
298 - Instruments' default pitch bend range is now +-2 semi tones.
299 - Fixed CRC checksums being wrong sometimes.

301 of passed original file.
302 - Added support for serializing & deserializing DimensionRegion
303 objects (and crossfade_t and leverage_ctrl_t objects).
304 - Added enum reflection API functions for retrieving enum declaration type
305 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
306 - Exception class now has a variadic constructor which allows to add
307 textual format specifiers like with printf().
308 - On unknown leverage controller exception: show precise unknown leverage
309 controller number found.
310 - Ignore invalid leverage controller types and just show a warning on the
311 console instead of throwing an exception.
312 - Added new struct eg_opt_t and new class member variable
313 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
314 extension to the gig file format, which allows to override the default
315 behavior of the first two EGs' state machines.
316 - Fixed undefined behavior when loading a gig file with invalid
317 velocity curve parameters (fixes CVE-2017-12951).
318 - Fixed undefined behavior when loading a gig file with invalid wave
319 pool index number (fixes CVE-2017-12954).
320
321 * src/DLS.cpp, src/DLS.h:
322 - Sample: wave pool offsets are now 64 bits (to allow support for files
323 larger than 4 GB).
324 - Exception class now has a variadic constructor which allows to add
325 textual format specifiers like with printf().
326
327 * src/RIFF.cpp, src/RIFF.h:
328 - added support for RIFF files larger than 4 GB, by default the required
329 internal RIFF file offset size is automatically detected (that is RIFF
330 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
331 automatically use 64 bit offsets), a particular offset size can be forced
332 with a new option added to the RIFF File constructor though
333 - when saving a modified, grown RIFF file, the temporary file size during
334 Save() operation will no longer be larger than the final grown file size
335 - Exception class now has a variadic constructor which allows to add
336 textual format specifiers like with printf().
337
338 * src/Serialization.cpp, src/Serialization.h:
339 - Archive: Added method isModified().
340 - Archive: Added method setAutoValue().
341 - Archive: Added method setIntValue().
342 - Archive: Added method setRealValue().
343 - Archive: Added method setBoolValue().
344 - Archive: Added method setEnumValue().
345 - Archive: Added method valueAsString().
346 - Archive::rawData(): Automatically re-encode new raw data stream if
347 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
348 - Object: Added method memberByUID().
349 - Object: remove() method is now protected.
350 - Archive: Added method removeMember().
351 - Archive: Added methods name() and setName().
352 - Archive: Added methods comment() and setComment().
353 - Archive: Added methods timeStampCreated(), timeStampModified(),
354 dateTimeCreated() and dateTimeModified().
355 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
356 - DataType: Implemented demangling C++ type names (for methods
357 asLongDescr() and customTypeName(bool demangle=false)).
358 - Archive::setAutoValue(): Handle human readable boolean text
359 representations like "yes", "no", "true", "false" as expected.
360 - Exception class now has a variadic constructor which allows to add
361 textual format specifiers like with printf().
362 - DataType fix: Retain backward compatibility to older versions of native
363 C++ classes/structs.
364
365 * src/Akai.cpp:
366 - Fixed compilation error with recent, more strict compilers.
367
368 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
369 - improved output of non-ascii characters in usage messages
370 - fixed printf format strings
371
372 * src/tools/korg2gig.cpp:
373 - fixed c++11 narrowing warnings
374 - fixed fine tuning which was not translated at all
375
376 * src/tools/gigdump.cpp:
377 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
378 dimension regions
379 - additionally print RIFF chunk file offset and RIFF chunk size of sample
380 data
381 - added and implemented new parameter "--verify" which allows to check
382 the raw wave form data integrity of all samples
383 - added and implemented new parameter "--rebuild-checksums" which allows
384 to recalculate the CRC32 checksum of all samples' raw wave data and
385 rebuilding the gig file's global checksum table (i.e. in case the
386 file's checksum table was damaged)
387 - print samples' CRC32 checksums
388 - Print the new EG behavior options (eg_opt_t).
389
390 * src/tools/gigextract.cpp:
391 - Fix: if sample name contains a path separator (slash or backslash) then
392 replace them by a minus sign to avoid file system issues.
393
394 * src/tools/gig2stereo.cpp:
395 - Also merge mono sample pairs with non matching loop information if
396 argument --incompatible was given.
397

435
436 * AKAI file format:
437 - Added Linux/POSIX ported version of libakai. Note that libakai is released

622 not saved correctly
623 - write support: 24 bit samples can now be written
624 - write support: version 3 is now the default for new files

627 list in v3 files now always has 128 entries, several parameters
628 where incorrectly saved due to an operator precedence mistake
629 - DeleteSample now removes all references to the deleted sample
630 - AddDimension now copies all parameters from existing dimension
631 regions and also makes sure that the samplechannel dimension is
632 placed first in the list of dimensions.

634 parent Region
635 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

657 velocity (gig v3 feature)
658 - added "smart midi" and "round robin keyboard" dimensions
659 - added new method File::DeleteGroupOnly() which only deletes the given
660 group but moves all its members to another group, the other method,
661 that is File::DeleteGroup() now removes not just the group, but also
662 all the samples that belong to that group
663 - fixed crash which occured on interfering File::DeleteSample() and

811 (patch by Andreas Persson)
812 - added some file format compatibility checks
813 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

868 SuSE and Fedora)
869 - fixed generation of Doxygen API documentation (now also included in
870 RPM and Debian packages)
871
872 * src/gig.cpp, src/gig.h:
873 - fixed / improved accuracy of all three velocity to volume
874 transformation functions a.k.a. 'nonlinear','linear','special'
875 (patch by Andreas Persson)
876 - denormals are filtered from the velocity to volume tables
877 - bugfix for dimension region switching (wrong handling of the release
878 trigger dimension, no bit range check for dimensions of split type

882 - added class attribute 'Layers' to class 'gig::Region'
883 - symbol prototyping of gig::Region (fixes build failure with qsampler)
884

908
909 * general changes:
910 - various big endian specific corrections

915 - added man pages for the command line tools
916 (gigextract, gigdump, dlsdump, rifftree)
917
918 * src/gig.cpp, src/gig.h:
919 - fixed bug in decompression algorithm which caused it not to detect
920 the end of a stream
921 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
922 takes the MIDI key velocity value as an argument and returns the
923 appropriate volume factor (0.0 ... 1.0) for the sample to be played
924 back, the velocity curve transformation functions used for this are
925 only an approximation so far
926 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
927 'Sample::LoopSize' which reflected wrong values
928 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
929 measured in sample points instead of byte offset
930 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
931 'Sample::FineTune'
932 - added class attribute 'Sample::LoopSize'
933 - added method GetInstrument(uint index) to class 'File'
934 - added ReadAndLoop() method to class 'Sample' which is an extension to
935 the normal Read() method to honor the sample's looping information
936 while streaming from disk
937 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
938 'eg2_ctrl_t': replaced this huge enumeration by a structure which
939 reflects the MIDI controller number in case of an ordinary control
940 change controller (this saves a huge switch-case block in the
941 application of the library user)
942 - renamed following attributes in class 'DimensionRegion':
943 'AttenuationContol' -> 'AttenuationController',
944 'InvertAttenuationControl' -> 'InvertAttenuationController',
945 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
946 - minor fix in API documentation for method GetVelocityAttenuation() in
947 class 'DimensionRegion'
948
949 * src/RIFF.cpp, src/RIFF.h:
950 - added additional API documentation
951 - minor fix in Chunk::Read() method (only a minor efficiency issue)
