152 Version 4.3.0 (9 May 2021)
153
154 * general changes:
155 - Require at least a C++11 compliant compiler.
156 - Require some UUID generating function by underlying system.
157
158 * src/gig.cpp, src/gig.h:
159 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
160 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
161 allow to define override LFOs' wave form (e.g. saw or square instead of
162 the default wave form which was always sine in the original
163 Gigasampler/GigaStudio software).
164 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
165 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
166 move the start point horizontally of the LFOs' waves (0�� ... 360��).
167 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
168 (the original Gigasampler/GigaStudio software only had that flip phase
169 option for LFO1 and LFO2).
170 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
171 Region::UsesAnyGigFormatExtension(),
172 Instrument::UsesAnyGigFormatExtension() and
173 File::UsesAnyGigFormatExtension() (however only as private methods yet,
174 see comments on methods why).
175 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
176 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
177 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
178 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
179 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
180 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
181 (patch by Ivan Maguidhir).
182 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
183 (original patch by Ivan Maguidhir).
184 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
185 dimensions being in different order after deleting a dimension zone.
186 - Script: Generate a persistent UUID for each script.
187 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
188 accordingly added new methods to Instrument class:
189 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
190 GetScriptPatchVariable(), SetScriptPatchVariable(),
191 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
192 as child of our '3LS ' list chunk on Instrument level.
193 - Fixed undefined behaviour when modifying script slots on an instrument
194 that had been cloned and not been saved yet (e.g. unintended modification
195 of original instrument's script slots, and crash on Instrument destruction
196 due to double free of pScriptRefs).
197
198 * src/Serialization.cpp, src/Serialization.h:
199 - Fixed broken Archive(RawData) constructor which always threw an
200 Exception.
201 - Added built-in support for C++ String objects (a.k.a. std::string
202 from the STL) and bumped Srx format version to 1.1 for that reason.
203 - Fixed assertion fault on some systems if a member variable defined was
204 serialized which was declared as size_t or ssize_t data type.
205 - Added new method Archive::operation() which allows applications to
206 distinguish between serialization vs. deserialization in their
207 serialize() method implementations.
208 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
209 the STL).
210 - Member offsets are now signed and for (newly added support of) member
211 variables on the heap -1 is always used as offset instead.
212 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
213 STL).
214 - DataType: Added optional 2nd custom type name.
215 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
216 STL).
217
218 * src/helper.h:
219 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
220 function call.
221
222 * src/tools/gigdump.cpp:
223 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
224 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
225 LFO2FlipPhase and LFO3FlipPhase.
226
227 Version 4.2.0 (25 Jul 2019)
228
229 * general changes:
230 - Added MSVC build support (anonymous patch from mailing list).
231 - Introduced CMake build support (yet constrained for building with MSVC)
232 (anonymous patch from mailing list).
233 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
234 destructors. Added new virtual method DeleteChunks() to those classes
235 for this which must be explicitly called instead to remove their RIFF
236 chunks.
237 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
238 of zero; which is unsafe per se.
239 - Added C++11 "override" keyword where appropriate.
240 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
241 of their actions when not passing a progress_t callback structure.
242
243 * src/gig.cpp, src/gig.h:
244 - Fixed Doxygen API comments for enum types (currently latest Doxygen
245 [v1.8.13] only supports C comments in macro arguments expansion, but
246 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
247 the Doxygen source code, which currently also filter out new line
248 \n chars).
249 - Added new method File::CountSamples().
250 - Added new method File::CountInstruments().
251 - Fixed gig v4 files falsely being handled as v2 format
252 (patch by Ivan Maguidhir).
253 - Added gig v4 version identifier (File::VERSION_4).
254 - GIG FORMAT EXTENSION: Added attribute
255 DimensionRegion::SustainReleaseTrigger which allows to define whether
256 a sustain pedal up event shall cause a release trigger sample to be
257 played (default: don't play release trigger sample by sustain pedal).
258 - GIG FORMAT EXTENSION: Added attribute
259 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
260 regular behaviour of playing release trigger sample on MIDI note-off
261 events.
262 - Introduced support for writing extension files (.gx01, .gx02, ...)
263 (original patch by Ivan Maguidhir).
264 - Many gig classes derive now from DLS::Storage (see DLS changes below).
265 - Added File::GetRiffFile() method.
266
267 * src/DLS.cpp, src/DLS.h:
268 - File: Fixed implicitly allocated RIFF::File object never been freed.
269 - Added new abstract interface base class DLS::Storage which is derived by
270 the respective classes for implementing (the old) UpdateChunks() and the
271 new DeleteChunks() method.
272 - Added File::GetRiffFile() method.
273
274 * src/sf2.cpp, src/sf2.h:
275 - Added Sample::GetFile() method.
276 - Added File::GetRiffFile() method.
277
278 * src/Serialization.cpp, src/Serialization.h:
279 - Hide pure internal declarations from header file to avoid numerous
280 compiler warnings when building and linking against the public API.
281 - Fixed comparision logic bug
282 - Fixed memory leak in DataType::customTypeName().
283
284 * src/RIFF.cpp, src/RIFF.h:
285 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
286 caused a resource leak
287 - Avoid compiler warning when building for 32 bit windows.
288 - Added new method progress_t::subdivide().
289 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
290 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
291 allows a more fine graded control into which portions the subtasks are
292 divided to.
293
294 * src/tools/gigdump.cpp:
295 - Added command line option --instrument-names which causes only
296 instrument names and their index numbers to be printed.
297
298 Version 4.1.0 (25 Nov 2017)
299 * general changes:
300 - removed 2 GB limitation when loading a gig or DLS file
301 - using now native integer size where appropriate
302 - fixed minor issues with man pages (patch by Debian maintainer)
303 - fixed various spelling mistakes (patch by Debian maintainer)
304 - Added new "Serialization" framework (and equally named namespace)
305 which allows to serialize and deserialize native C++ objects
306 in a portable, easy and flexible way.
307 - print compiler warning if no RTTI available
308 - Fixed potential crash in command line tools gig2stereo, korg2gig,
309 korgdump and sf2extract.
310 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
311 (original patch by Paul Brossier, slightly modified).
312 - Debian: Fixed packaging error about invalid substitution variable
313 "Source-Version".
314 - Raised Debian compatibility level to Debian 9 "Stretch".
315
316 * src/gig.cpp, src/gig.h:
317 - fixed bug in Script::SetGroup: the script chunk wasn't moved
318 - fixed compilation error with clang 3.4
319 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
320 as one single monolithic gig file. In case .gig file is >= 2GB expect a
321 large monolithic file, otherwise if .gig file is < 2 GB check for
322 "extension" files (.gx01, .gx02, ...) instead.
323 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
324 if there were dimensions after the velocity dimension: it only created
325 valid velocity tables for cases of dimensions lower than the velocity
326 dimension.
327 - added new method Sample::VerifyWaveData() which allows to check whether
328 a sample had been damaged for some reason
329 - Fix: samples' CRC checksums were damaged on file structure changes.
330 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
331 - Added new method Sample::GetWaveDataCRC32Checksum().

336 of passed original file.
337 - Added support for serializing & deserializing DimensionRegion
338 objects (and crossfade_t and leverage_ctrl_t objects).
339 - Added enum reflection API functions for retrieving enum declaration type
340 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
341 - Exception class now has a variadic constructor which allows to add
342 textual format specifiers like with printf().
343 - On unknown leverage controller exception: show precise unknown leverage
344 controller number found.
345 - Ignore invalid leverage controller types and just show a warning on the
346 console instead of throwing an exception.
347 - Added new struct eg_opt_t and new class member variable
348 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
349 extension to the gig file format, which allows to override the default
350 behavior of the first two EGs' state machines.
351 - Fixed undefined behavior when loading a gig file with invalid
352 velocity curve parameters (fixes CVE-2017-12951).
353 - Fixed undefined behavior when loading a gig file with invalid wave
354 pool index number (fixes CVE-2017-12954).
355
356 * src/DLS.cpp, src/DLS.h:
357 - Sample: wave pool offsets are now 64 bits (to allow support for files
358 larger than 4 GB).
359 - Exception class now has a variadic constructor which allows to add
360 textual format specifiers like with printf().
361
362 * src/RIFF.cpp, src/RIFF.h:
363 - added support for RIFF files larger than 4 GB, by default the required
364 internal RIFF file offset size is automatically detected (that is RIFF
365 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
366 automatically use 64 bit offsets), a particular offset size can be forced
367 with a new option added to the RIFF File constructor though
368 - when saving a modified, grown RIFF file, the temporary file size during
369 Save() operation will no longer be larger than the final grown file size
370 - Exception class now has a variadic constructor which allows to add
371 textual format specifiers like with printf().
372
373 * src/Serialization.cpp, src/Serialization.h:
374 - Archive: Added method isModified().
375 - Archive: Added method setAutoValue().
376 - Archive: Added method setIntValue().
377 - Archive: Added method setRealValue().
378 - Archive: Added method setBoolValue().
379 - Archive: Added method setEnumValue().
380 - Archive: Added method valueAsString().
381 - Archive::rawData(): Automatically re-encode new raw data stream if
382 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
383 - Object: Added method memberByUID().
384 - Object: remove() method is now protected.
385 - Archive: Added method removeMember().
386 - Archive: Added methods name() and setName().
387 - Archive: Added methods comment() and setComment().
388 - Archive: Added methods timeStampCreated(), timeStampModified(),
389 dateTimeCreated() and dateTimeModified().
390 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
391 - DataType: Implemented demangling C++ type names (for methods
392 asLongDescr() and customTypeName(bool demangle=false)).
393 - Archive::setAutoValue(): Handle human readable boolean text
394 representations like "yes", "no", "true", "false" as expected.
395 - Exception class now has a variadic constructor which allows to add
396 textual format specifiers like with printf().
397 - DataType fix: Retain backward compatibility to older versions of native
398 C++ classes/structs.
399
400 * src/Akai.cpp:
401 - Fixed compilation error with recent, more strict compilers.
402
403 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

415 data
416 - added and implemented new parameter "--verify" which allows to check
417 the raw wave form data integrity of all samples
418 - added and implemented new parameter "--rebuild-checksums" which allows
419 to recalculate the CRC32 checksum of all samples' raw wave data and
420 rebuilding the gig file's global checksum table (i.e. in case the
421 file's checksum table was damaged)
422 - print samples' CRC32 checksums
423 - Print the new EG behavior options (eg_opt_t).
424
425 * src/tools/gigextract.cpp:
426 - Fix: if sample name contains a path separator (slash or backslash) then
427 replace them by a minus sign to avoid file system issues.
428
429 * src/tools/gig2stereo.cpp:
430 - Also merge mono sample pairs with non matching loop information if
431 argument --incompatible was given.

471 * AKAI file format:
472 - Added Linux/POSIX ported version of libakai. Note that libakai is released
473 under LGPL terms while libgig is released under GPL terms. To handle this
474 license difference appropriately the AKAI support part is built as
475 separate DLL (.so file).
476 - Fixed Mac OSX support so that the Akai lib files and tools compile without
477 any exotic third party libraries.
478 - Fixed various compilation errors for Windows.
479 - POSIX fix: open() requires third (mode) argument if used with O_CREAT
480 (fixes #219).

512 new one being dropped after save operation and the gig file being tainted
513 (chunks at wrong location in the RIFF tree).
514 - Added new method Instrument::MoveTo() which allows to rearrange the order
515 of instruments within the same gig file.
516

547 one allows to move the subchunk from the current list to another list
548 - POSIX: only assume -1 result value as error on open() calls
549 - POSIX: show operating system's error reason if opening a file failed

586 - bugfix: undefined behavior (e.g. endless loop) when opening zero
587 length files, now throws a RIFF::Exception instead (fixes bug #121)
588 - bugfix: destructor for base class RIFF::Chunk accessed members
589 of derived class RIFF::File, which is bad, and caused crashes
590 when using Visual C++
591 - bugfix: files that contain zero length RIFF lists were not read
592 correctly (fixes #127) (bug was introduced 2009-03-13)

657 not saved correctly
658 - write support: 24 bit samples can now be written

692 velocity (gig v3 feature)
693 - added "smart midi" and "round robin keyboard" dimensions
694 - added new method File::DeleteGroupOnly() which only deletes the given
695 group but moves all its members to another group, the other method,
696 that is File::DeleteGroup() now removes not just the group, but also
697 all the samples that belong to that group
698 - fixed crash which occured on interfering File::DeleteSample() and

905 RPM and Debian packages)
906
907 * src/gig.cpp, src/gig.h:
908 - fixed / improved accuracy of all three velocity to volume
909 transformation functions a.k.a. 'nonlinear','linear','special'
910 (patch by Andreas Persson)

943
944 * general changes:
945 - various big endian specific corrections

950 - added man pages for the command line tools
951 (gigextract, gigdump, dlsdump, rifftree)
952
953 * src/gig.cpp, src/gig.h:
954 - fixed bug in decompression algorithm which caused it not to detect
955 the end of a stream
956 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
957 takes the MIDI key velocity value as an argument and returns the
958 appropriate volume factor (0.0 ... 1.0) for the sample to be played
959 back, the velocity curve transformation functions used for this are
960 only an approximation so far
961 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
962 'Sample::LoopSize' which reflected wrong values
963 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
964 measured in sample points instead of byte offset
965 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
966 'Sample::FineTune'
967 - added class attribute 'Sample::LoopSize'
968 - added method GetInstrument(uint index) to class 'File'
969 - added ReadAndLoop() method to class 'Sample' which is an extension to
970 the normal Read() method to honor the sample's looping information
971 while streaming from disk
972 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
973 'eg2_ctrl_t': replaced this huge enumeration by a structure which
974 reflects the MIDI controller number in case of an ordinary control
975 change controller (this saves a huge switch-case block in the
976 application of the library user)
977 - renamed following attributes in class 'DimensionRegion':
978 'AttenuationContol' -> 'AttenuationController',
979 'InvertAttenuationControl' -> 'InvertAttenuationController',
980 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
981 - minor fix in API documentation for method GetVelocityAttenuation() in
982 class 'DimensionRegion'
983
984 * src/RIFF.cpp, src/RIFF.h:
