111 Version 4.3.0 (9 May 2021)
112
113 * general changes:
114 - Require at least a C++11 compliant compiler.
115 - Require some UUID generating function by underlying system.
116
117 * src/gig.cpp, src/gig.h:
118 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
119 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
120 allow to define override LFOs' wave form (e.g. saw or square instead of
121 the default wave form which was always sine in the original
122 Gigasampler/GigaStudio software).
123 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
124 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
125 move the start point horizontally of the LFOs' waves (0�� ... 360��).
126 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
127 (the original Gigasampler/GigaStudio software only had that flip phase
128 option for LFO1 and LFO2).
129 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
130 Region::UsesAnyGigFormatExtension(),
131 Instrument::UsesAnyGigFormatExtension() and
132 File::UsesAnyGigFormatExtension() (however only as private methods yet,
133 see comments on methods why).
134 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
135 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
136 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
137 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
138 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
139 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
140 (patch by Ivan Maguidhir).
141 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
142 (original patch by Ivan Maguidhir).
143 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
144 dimensions being in different order after deleting a dimension zone.
145 - Script: Generate a persistent UUID for each script.
146 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
147 accordingly added new methods to Instrument class:
148 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
149 GetScriptPatchVariable(), SetScriptPatchVariable(),
150 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
151 as child of our '3LS ' list chunk on Instrument level.
152 - Fixed undefined behaviour when modifying script slots on an instrument
153 that had been cloned and not been saved yet (e.g. unintended modification
154 of original instrument's script slots, and crash on Instrument destruction
155 due to double free of pScriptRefs).
156
157 * src/Serialization.cpp, src/Serialization.h:
158 - Fixed broken Archive(RawData) constructor which always threw an
159 Exception.
160 - Added built-in support for C++ String objects (a.k.a. std::string
161 from the STL) and bumped Srx format version to 1.1 for that reason.
162 - Fixed assertion fault on some systems if a member variable defined was
163 serialized which was declared as size_t or ssize_t data type.
164 - Added new method Archive::operation() which allows applications to
165 distinguish between serialization vs. deserialization in their
166 serialize() method implementations.
167 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
168 the STL).
169 - Member offsets are now signed and for (newly added support of) member
170 variables on the heap -1 is always used as offset instead.
171 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
172 STL).
173 - DataType: Added optional 2nd custom type name.
174 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
175 STL).
176
177 * src/helper.h:
178 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
179 function call.
180
181 * src/tools/gigdump.cpp:
182 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
183 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
184 LFO2FlipPhase and LFO3FlipPhase.
185
186 Version 4.2.0 (25 Jul 2019)
187
188 * general changes:
189 - Added MSVC build support (anonymous patch from mailing list).
190 - Introduced CMake build support (yet constrained for building with MSVC)
191 (anonymous patch from mailing list).
192 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
193 destructors. Added new virtual method DeleteChunks() to those classes
194 for this which must be explicitly called instead to remove their RIFF
195 chunks.
196 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
197 of zero; which is unsafe per se.
198 - Added C++11 "override" keyword where appropriate.
199 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
200 of their actions when not passing a progress_t callback structure.
201
202 * src/gig.cpp, src/gig.h:
203 - Fixed Doxygen API comments for enum types (currently latest Doxygen
204 [v1.8.13] only supports C comments in macro arguments expansion, but
205 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
206 the Doxygen source code, which currently also filter out new line
207 \n chars).
208 - Added new method File::CountSamples().
209 - Added new method File::CountInstruments().
210 - Fixed gig v4 files falsely being handled as v2 format
211 (patch by Ivan Maguidhir).
212 - Added gig v4 version identifier (File::VERSION_4).
213 - GIG FORMAT EXTENSION: Added attribute
214 DimensionRegion::SustainReleaseTrigger which allows to define whether
215 a sustain pedal up event shall cause a release trigger sample to be
216 played (default: don't play release trigger sample by sustain pedal).
217 - GIG FORMAT EXTENSION: Added attribute
218 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
219 regular behaviour of playing release trigger sample on MIDI note-off
220 events.
221 - Introduced support for writing extension files (.gx01, .gx02, ...)
222 (original patch by Ivan Maguidhir).
223 - Many gig classes derive now from DLS::Storage (see DLS changes below).
224 - Added File::GetRiffFile() method.
225
226 * src/DLS.cpp, src/DLS.h:
227 - File: Fixed implicitly allocated RIFF::File object never been freed.
228 - Added new abstract interface base class DLS::Storage which is derived by
229 the respective classes for implementing (the old) UpdateChunks() and the
230 new DeleteChunks() method.
231 - Added File::GetRiffFile() method.
232
233 * src/sf2.cpp, src/sf2.h:
234 - Added Sample::GetFile() method.
235 - Added File::GetRiffFile() method.
236
237 * src/Serialization.cpp, src/Serialization.h:
238 - Hide pure internal declarations from header file to avoid numerous
239 compiler warnings when building and linking against the public API.
240 - Fixed comparision logic bug
241 - Fixed memory leak in DataType::customTypeName().
242
243 * src/RIFF.cpp, src/RIFF.h:
244 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
245 caused a resource leak
246 - Avoid compiler warning when building for 32 bit windows.
247 - Added new method progress_t::subdivide().
248 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
249 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
250 allows a more fine graded control into which portions the subtasks are
251 divided to.
252
253 * src/tools/gigdump.cpp:
254 - Added command line option --instrument-names which causes only
255 instrument names and their index numbers to be printed.
256
257 Version 4.1.0 (25 Nov 2017)
258 * general changes:
259 - removed 2 GB limitation when loading a gig or DLS file
260 - using now native integer size where appropriate
261 - fixed minor issues with man pages (patch by Debian maintainer)
262 - fixed various spelling mistakes (patch by Debian maintainer)
263 - Added new "Serialization" framework (and equally named namespace)
264 which allows to serialize and deserialize native C++ objects
265 in a portable, easy and flexible way.
266 - print compiler warning if no RTTI available
267 - Fixed potential crash in command line tools gig2stereo, korg2gig,
268 korgdump and sf2extract.
269 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
270 (original patch by Paul Brossier, slightly modified).
271 - Debian: Fixed packaging error about invalid substitution variable
272 "Source-Version".
273 - Raised Debian compatibility level to Debian 9 "Stretch".
274
275 * src/gig.cpp, src/gig.h:
276 - fixed bug in Script::SetGroup: the script chunk wasn't moved
277 - fixed compilation error with clang 3.4
278 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
279 as one single monolithic gig file. In case .gig file is >= 2GB expect a
280 large monolithic file, otherwise if .gig file is < 2 GB check for
281 "extension" files (.gx01, .gx02, ...) instead.
282 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
283 if there were dimensions after the velocity dimension: it only created
284 valid velocity tables for cases of dimensions lower than the velocity
285 dimension.
286 - added new method Sample::VerifyWaveData() which allows to check whether
287 a sample had been damaged for some reason
288 - Fix: samples' CRC checksums were damaged on file structure changes.
289 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
290 - Added new method Sample::GetWaveDataCRC32Checksum().
291 - Changed default value of EG2Release (filter release time) to 60s.
292 - Instruments' default pitch bend range is now +-2 semi tones.
293 - Fixed CRC checksums being wrong sometimes.
294 - Fix: method File::AddContentOf() did not clone script groups and scripts
295 of passed original file.
296 - Added support for serializing & deserializing DimensionRegion
297 objects (and crossfade_t and leverage_ctrl_t objects).
298 - Added enum reflection API functions for retrieving enum declaration type
299 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
300 - Exception class now has a variadic constructor which allows to add
301 textual format specifiers like with printf().
302 - On unknown leverage controller exception: show precise unknown leverage
303 controller number found.
304 - Ignore invalid leverage controller types and just show a warning on the
305 console instead of throwing an exception.
306 - Added new struct eg_opt_t and new class member variable
307 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
308 extension to the gig file format, which allows to override the default
309 behavior of the first two EGs' state machines.
310 - Fixed undefined behavior when loading a gig file with invalid
311 velocity curve parameters (fixes CVE-2017-12951).
312 - Fixed undefined behavior when loading a gig file with invalid wave
313 pool index number (fixes CVE-2017-12954).
314
315 * src/DLS.cpp, src/DLS.h:
316 - Sample: wave pool offsets are now 64 bits (to allow support for files
317 larger than 4 GB).
318 - Exception class now has a variadic constructor which allows to add
319 textual format specifiers like with printf().
320
321 * src/RIFF.cpp, src/RIFF.h:
322 - added support for RIFF files larger than 4 GB, by default the required
323 internal RIFF file offset size is automatically detected (that is RIFF
324 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
325 automatically use 64 bit offsets), a particular offset size can be forced
326 with a new option added to the RIFF File constructor though
327 - when saving a modified, grown RIFF file, the temporary file size during
328 Save() operation will no longer be larger than the final grown file size
329 - Exception class now has a variadic constructor which allows to add
330 textual format specifiers like with printf().
331
332 * src/Serialization.cpp, src/Serialization.h:
333 - Archive: Added method isModified().
334 - Archive: Added method setAutoValue().
335 - Archive: Added method setIntValue().
336 - Archive: Added method setRealValue().
337 - Archive: Added method setBoolValue().
338 - Archive: Added method setEnumValue().
339 - Archive: Added method valueAsString().
340 - Archive::rawData(): Automatically re-encode new raw data stream if
341 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
342 - Object: Added method memberByUID().
343 - Object: remove() method is now protected.
344 - Archive: Added method removeMember().
345 - Archive: Added methods name() and setName().
346 - Archive: Added methods comment() and setComment().
347 - Archive: Added methods timeStampCreated(), timeStampModified(),
348 dateTimeCreated() and dateTimeModified().
349 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
350 - DataType: Implemented demangling C++ type names (for methods
351 asLongDescr() and customTypeName(bool demangle=false)).
352 - Archive::setAutoValue(): Handle human readable boolean text
353 representations like "yes", "no", "true", "false" as expected.
354 - Exception class now has a variadic constructor which allows to add
355 textual format specifiers like with printf().
356 - DataType fix: Retain backward compatibility to older versions of native
357 C++ classes/structs.
358
359 * src/Akai.cpp:
360 - Fixed compilation error with recent, more strict compilers.
361
362 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
363 - improved output of non-ascii characters in usage messages

371 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
372 dimension regions
373 - additionally print RIFF chunk file offset and RIFF chunk size of sample
374 data
375 - added and implemented new parameter "--verify" which allows to check
376 the raw wave form data integrity of all samples
377 - added and implemented new parameter "--rebuild-checksums" which allows
378 to recalculate the CRC32 checksum of all samples' raw wave data and
379 rebuilding the gig file's global checksum table (i.e. in case the
380 file's checksum table was damaged)
381 - print samples' CRC32 checksums
382 - Print the new EG behavior options (eg_opt_t).
383
384 * src/tools/gigextract.cpp:
385 - Fix: if sample name contains a path separator (slash or backslash) then
386 replace them by a minus sign to avoid file system issues.
387
388 * src/tools/gig2stereo.cpp:
389 - Also merge mono sample pairs with non matching loop information if
390 argument --incompatible was given.
391

429
430 * AKAI file format:
431 - Added Linux/POSIX ported version of libakai. Note that libakai is released

471 new one being dropped after save operation and the gig file being tainted
472 (chunks at wrong location in the RIFF tree).
473 - Added new method Instrument::MoveTo() which allows to rearrange the order
474 of instruments within the same gig file.
475

616 not saved correctly
617 - write support: 24 bit samples can now be written

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

628 parent Region
629 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

864 RPM and Debian packages)
865
866 * src/gig.cpp, src/gig.h:
867 - fixed / improved accuracy of all three velocity to volume
868 transformation functions a.k.a. 'nonlinear','linear','special'
869 (patch by Andreas Persson)
870 - denormals are filtered from the velocity to volume tables

902
903 * general changes:
904 - various big endian specific corrections

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

947 * src/gigdump.cpp:
948 - added printout of samples' looping informations
949
950 Version 0.6.0 (3 Nov 2003)
