108 Version 4.3.0 (9 May 2021)
109
110 * general changes:
111 - Require at least a C++11 compliant compiler.
112 - Require some UUID generating function by underlying system.
113
114 * src/gig.cpp, src/gig.h:
115 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
116 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
117 allow to define override LFOs' wave form (e.g. saw or square instead of
118 the default wave form which was always sine in the original
119 Gigasampler/GigaStudio software).
120 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
121 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
122 move the start point horizontally of the LFOs' waves (0�� ... 360��).
123 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
124 (the original Gigasampler/GigaStudio software only had that flip phase
125 option for LFO1 and LFO2).
126 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
127 Region::UsesAnyGigFormatExtension(),
128 Instrument::UsesAnyGigFormatExtension() and
129 File::UsesAnyGigFormatExtension() (however only as private methods yet,
130 see comments on methods why).
131 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
132 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
133 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
134 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
135 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
136 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
137 (patch by Ivan Maguidhir).
138 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
139 (original patch by Ivan Maguidhir).
140 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
141 dimensions being in different order after deleting a dimension zone.
142 - Script: Generate a persistent UUID for each script.
143 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
144 accordingly added new methods to Instrument class:
145 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
146 GetScriptPatchVariable(), SetScriptPatchVariable(),
147 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
148 as child of our '3LS ' list chunk on Instrument level.
149 - Fixed undefined behaviour when modifying script slots on an instrument
150 that had been cloned and not been saved yet (e.g. unintended modification
151 of original instrument's script slots, and crash on Instrument destruction
152 due to double free of pScriptRefs).
153
154 * src/Serialization.cpp, src/Serialization.h:
155 - Fixed broken Archive(RawData) constructor which always threw an
156 Exception.
157 - Added built-in support for C++ String objects (a.k.a. std::string
158 from the STL) and bumped Srx format version to 1.1 for that reason.
159 - Fixed assertion fault on some systems if a member variable defined was
160 serialized which was declared as size_t or ssize_t data type.
161 - Added new method Archive::operation() which allows applications to
162 distinguish between serialization vs. deserialization in their
163 serialize() method implementations.
164 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
165 the STL).
166 - Member offsets are now signed and for (newly added support of) member
167 variables on the heap -1 is always used as offset instead.
168 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
169 STL).
170 - DataType: Added optional 2nd custom type name.
171 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
172 STL).
173
174 * src/helper.h:
175 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
176 function call.
177
178 * src/tools/gigdump.cpp:
179 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
180 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
181 LFO2FlipPhase and LFO3FlipPhase.
182
183 Version 4.2.0 (25 Jul 2019)
184

186 - Added MSVC build support (anonymous patch from mailing list).
187 - Introduced CMake build support (yet constrained for building with MSVC)
188 (anonymous patch from mailing list).
189 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
190 destructors. Added new virtual method DeleteChunks() to those classes
191 for this which must be explicitly called instead to remove their RIFF
192 chunks.
193 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
194 of zero; which is unsafe per se.
195 - Added C++11 "override" keyword where appropriate.
196 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
197 of their actions when not passing a progress_t callback structure.
198
199 * src/gig.cpp, src/gig.h:
200 - Fixed Doxygen API comments for enum types (currently latest Doxygen
201 [v1.8.13] only supports C comments in macro arguments expansion, but
202 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
203 the Doxygen source code, which currently also filter out new line
204 \n chars).
205 - Added new method File::CountSamples().
206 - Added new method File::CountInstruments().
207 - Fixed gig v4 files falsely being handled as v2 format
208 (patch by Ivan Maguidhir).
209 - Added gig v4 version identifier (File::VERSION_4).
210 - GIG FORMAT EXTENSION: Added attribute
211 DimensionRegion::SustainReleaseTrigger which allows to define whether
212 a sustain pedal up event shall cause a release trigger sample to be
213 played (default: don't play release trigger sample by sustain pedal).
214 - GIG FORMAT EXTENSION: Added attribute
215 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
216 regular behaviour of playing release trigger sample on MIDI note-off
217 events.
218 - Introduced support for writing extension files (.gx01, .gx02, ...)
219 (original patch by Ivan Maguidhir).
220 - Many gig classes derive now from DLS::Storage (see DLS changes below).
221 - Added File::GetRiffFile() method.
222
223 * src/DLS.cpp, src/DLS.h:
224 - File: Fixed implicitly allocated RIFF::File object never been freed.
225 - Added new abstract interface base class DLS::Storage which is derived by
226 the respective classes for implementing (the old) UpdateChunks() and the
227 new DeleteChunks() method.
228 - Added File::GetRiffFile() method.
229
230 * src/sf2.cpp, src/sf2.h:
231 - Added Sample::GetFile() method.
232 - Added File::GetRiffFile() method.
233
234 * src/Serialization.cpp, src/Serialization.h:
235 - Hide pure internal declarations from header file to avoid numerous
236 compiler warnings when building and linking against the public API.
237 - Fixed comparision logic bug
238 - Fixed memory leak in DataType::customTypeName().
239
240 * src/RIFF.cpp, src/RIFF.h:
241 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
242 caused a resource leak
243 - Avoid compiler warning when building for 32 bit windows.
244 - Added new method progress_t::subdivide().
245 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
246 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
247 allows a more fine graded control into which portions the subtasks are
248 divided to.
249
250 * src/tools/gigdump.cpp:
251 - Added command line option --instrument-names which causes only
252 instrument names and their index numbers to be printed.
253
254 Version 4.1.0 (25 Nov 2017)
255 * general changes:
256 - removed 2 GB limitation when loading a gig or DLS file
257 - using now native integer size where appropriate
258 - fixed minor issues with man pages (patch by Debian maintainer)
259 - fixed various spelling mistakes (patch by Debian maintainer)
260 - Added new "Serialization" framework (and equally named namespace)
261 which allows to serialize and deserialize native C++ objects
262 in a portable, easy and flexible way.
263 - print compiler warning if no RTTI available
264 - Fixed potential crash in command line tools gig2stereo, korg2gig,
265 korgdump and sf2extract.
266 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
267 (original patch by Paul Brossier, slightly modified).
268 - Debian: Fixed packaging error about invalid substitution variable
269 "Source-Version".
270 - Raised Debian compatibility level to Debian 9 "Stretch".
271
272 * src/gig.cpp, src/gig.h:
273 - fixed bug in Script::SetGroup: the script chunk wasn't moved
274 - fixed compilation error with clang 3.4
275 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
276 as one single monolithic gig file. In case .gig file is >= 2GB expect a
277 large monolithic file, otherwise if .gig file is < 2 GB check for
278 "extension" files (.gx01, .gx02, ...) instead.
279 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
280 if there were dimensions after the velocity dimension: it only created
281 valid velocity tables for cases of dimensions lower than the velocity
282 dimension.
283 - added new method Sample::VerifyWaveData() which allows to check whether
284 a sample had been damaged for some reason
285 - Fix: samples' CRC checksums were damaged on file structure changes.
286 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
287 - Added new method Sample::GetWaveDataCRC32Checksum().
288 - Changed default value of EG2Release (filter release time) to 60s.
289 - Instruments' default pitch bend range is now +-2 semi tones.
290 - Fixed CRC checksums being wrong sometimes.
291 - Fix: method File::AddContentOf() did not clone script groups and scripts
292 of passed original file.
293 - Added support for serializing & deserializing DimensionRegion
294 objects (and crossfade_t and leverage_ctrl_t objects).
295 - Added enum reflection API functions for retrieving enum declaration type
296 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
297 - Exception class now has a variadic constructor which allows to add
298 textual format specifiers like with printf().
299 - On unknown leverage controller exception: show precise unknown leverage
300 controller number found.
301 - Ignore invalid leverage controller types and just show a warning on the
302 console instead of throwing an exception.
303 - Added new struct eg_opt_t and new class member variable
304 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
305 extension to the gig file format, which allows to override the default
306 behavior of the first two EGs' state machines.
307 - Fixed undefined behavior when loading a gig file with invalid
308 velocity curve parameters (fixes CVE-2017-12951).
309 - Fixed undefined behavior when loading a gig file with invalid wave
310 pool index number (fixes CVE-2017-12954).
311
312 * src/DLS.cpp, src/DLS.h:
313 - Sample: wave pool offsets are now 64 bits (to allow support for files
314 larger than 4 GB).
315 - Exception class now has a variadic constructor which allows to add
316 textual format specifiers like with printf().
317
318 * src/RIFF.cpp, src/RIFF.h:
319 - added support for RIFF files larger than 4 GB, by default the required
320 internal RIFF file offset size is automatically detected (that is RIFF
321 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
322 automatically use 64 bit offsets), a particular offset size can be forced
323 with a new option added to the RIFF File constructor though
324 - when saving a modified, grown RIFF file, the temporary file size during
325 Save() operation will no longer be larger than the final grown file size
326 - Exception class now has a variadic constructor which allows to add
327 textual format specifiers like with printf().
328
329 * src/Serialization.cpp, src/Serialization.h:
330 - Archive: Added method isModified().
331 - Archive: Added method setAutoValue().
332 - Archive: Added method setIntValue().
333 - Archive: Added method setRealValue().
334 - Archive: Added method setBoolValue().
335 - Archive: Added method setEnumValue().
336 - Archive: Added method valueAsString().
337 - Archive::rawData(): Automatically re-encode new raw data stream if
338 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
339 - Object: Added method memberByUID().
340 - Object: remove() method is now protected.
341 - Archive: Added method removeMember().
342 - Archive: Added methods name() and setName().
343 - Archive: Added methods comment() and setComment().
344 - Archive: Added methods timeStampCreated(), timeStampModified(),
345 dateTimeCreated() and dateTimeModified().
346 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
347 - DataType: Implemented demangling C++ type names (for methods
348 asLongDescr() and customTypeName(bool demangle=false)).
349 - Archive::setAutoValue(): Handle human readable boolean text
350 representations like "yes", "no", "true", "false" as expected.
351 - Exception class now has a variadic constructor which allows to add
352 textual format specifiers like with printf().
353 - DataType fix: Retain backward compatibility to older versions of native
354 C++ classes/structs.
355
356 * src/Akai.cpp:
357 - Fixed compilation error with recent, more strict compilers.
358
359 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
360 - improved output of non-ascii characters in usage messages

371 data
372 - added and implemented new parameter "--verify" which allows to check
373 the raw wave form data integrity of all samples
374 - added and implemented new parameter "--rebuild-checksums" which allows
375 to recalculate the CRC32 checksum of all samples' raw wave data and
376 rebuilding the gig file's global checksum table (i.e. in case the
377 file's checksum table was damaged)
378 - print samples' CRC32 checksums
379 - Print the new EG behavior options (eg_opt_t).
380
381 * src/tools/gigextract.cpp:
382 - Fix: if sample name contains a path separator (slash or backslash) then
383 replace them by a minus sign to avoid file system issues.
384
385 * src/tools/gig2stereo.cpp:
386 - Also merge mono sample pairs with non matching loop information if
387 argument --incompatible was given.
388

426
427 * AKAI file format:
428 - Added Linux/POSIX ported version of libakai. Note that libakai is released

503 one allows to move the subchunk from the current list to another list
504 - POSIX: only assume -1 result value as error on open() calls
505 - POSIX: show operating system's error reason if opening a file failed
506 - Added support for custom progress notification while saving to RIFF file.

538 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
539 is not written physically yet (#82)
540 - bugfix: saving to the same file after the file size had been
541 decreased sometimes also made the file corrupt!
542 - bugfix: undefined behavior (e.g. endless loop) when opening zero
543 length files, now throws a RIFF::Exception instead (fixes bug #121)

590 instrument constructors
591 - clear unused fields when saving samples and regions
592 - fixed write support bugs: v3 dimension limits and chunksize

612 when dimensions were added or deleted, v3 wave pool offsets were
613 not saved correctly
614 - write support: 24 bit samples can now be written

618 list in v3 files now always has 128 entries, several parameters
619 where incorrectly saved due to an operator precedence mistake
620 - DeleteSample now removes all references to the deleted sample
621 - AddDimension now copies all parameters from existing dimension
622 regions and also makes sure that the samplechannel dimension is
623 placed first in the list of dimensions.

625 parent Region
626 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

651 group but moves all its members to another group, the other method,
652 that is File::DeleteGroup() now removes not just the group, but also
653 all the samples that belong to that group
654 - fixed crash which occured on interfering File::DeleteSample() and

802 (patch by Andreas Persson)
803 - added some file format compatibility checks
804 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

859 SuSE and Fedora)
860 - fixed generation of Doxygen API documentation (now also included in
861 RPM and Debian packages)
862
863 * src/gig.cpp, src/gig.h:
864 - fixed / improved accuracy of all three velocity to volume
865 transformation functions a.k.a. 'nonlinear','linear','special'
866 (patch by Andreas Persson)
867 - denormals are filtered from the velocity to volume tables
868 - bugfix for dimension region switching (wrong handling of the release

899
900 * general changes:
901 - various big endian specific corrections

906 - added man pages for the command line tools
907 (gigextract, gigdump, dlsdump, rifftree)
908
909 * src/gig.cpp, src/gig.h:
910 - fixed bug in decompression algorithm which caused it not to detect
911 the end of a stream
912 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
913 takes the MIDI key velocity value as an argument and returns the
914 appropriate volume factor (0.0 ... 1.0) for the sample to be played
915 back, the velocity curve transformation functions used for this are
916 only an approximation so far
917 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
918 'Sample::LoopSize' which reflected wrong values
919 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
920 measured in sample points instead of byte offset
921 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
922 'Sample::FineTune'
923 - added class attribute 'Sample::LoopSize'
924 - added method GetInstrument(uint index) to class 'File'
925 - added ReadAndLoop() method to class 'Sample' which is an extension to
926 the normal Read() method to honor the sample's looping information
927 while streaming from disk
928 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
929 'eg2_ctrl_t': replaced this huge enumeration by a structure which
930 reflects the MIDI controller number in case of an ordinary control
931 change controller (this saves a huge switch-case block in the
932 application of the library user)
933 - renamed following attributes in class 'DimensionRegion':
934 'AttenuationContol' -> 'AttenuationController',
935 'InvertAttenuationControl' -> 'InvertAttenuationController',
936 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
937 - minor fix in API documentation for method GetVelocityAttenuation() in
938 class 'DimensionRegion'
939
940 * src/RIFF.cpp, src/RIFF.h:
941 - added additional API documentation
942 - minor fix in Chunk::Read() method (only a minor efficiency issue)
943
944 * src/gigdump.cpp:
945 - added printout of samples' looping informations
946
947 Version 0.6.0 (3 Nov 2003)
