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

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

398 data
399 - added and implemented new parameter "--verify" which allows to check
400 the raw wave form data integrity of all samples
401 - added and implemented new parameter "--rebuild-checksums" which allows
402 to recalculate the CRC32 checksum of all samples' raw wave data and
403 rebuilding the gig file's global checksum table (i.e. in case the
404 file's checksum table was damaged)
405 - print samples' CRC32 checksums
406 - Print the new EG behavior options (eg_opt_t).
407
408 * src/tools/gigextract.cpp:
409 - Fix: if sample name contains a path separator (slash or backslash) then
410 replace them by a minus sign to avoid file system issues.
411
412 * src/tools/gig2stereo.cpp:
413 - Also merge mono sample pairs with non matching loop information if
414 argument --incompatible was given.
415
416 * packaging changes:
417 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
418 auto detect whether it (sh/c)ould output its messages in color.

888 RPM and Debian packages)
889
890 * src/gig.cpp, src/gig.h:
891 - fixed / improved accuracy of all three velocity to volume
892 transformation functions a.k.a. 'nonlinear','linear','special'
893 (patch by Andreas Persson)
894 - denormals are filtered from the velocity to volume tables

900 - added class attribute 'Layers' to class 'gig::Region'
901 - symbol prototyping of gig::Region (fixes build failure with qsampler)
902

937 - fixed bug in decompression algorithm which caused it not to detect
938 the end of a stream
939 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
940 takes the MIDI key velocity value as an argument and returns the
941 appropriate volume factor (0.0 ... 1.0) for the sample to be played
942 back, the velocity curve transformation functions used for this are
943 only an approximation so far
944 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
945 'Sample::LoopSize' which reflected wrong values
946 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
947 measured in sample points instead of byte offset
948 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
949 'Sample::FineTune'
950 - added class attribute 'Sample::LoopSize'
951 - added method GetInstrument(uint index) to class 'File'
952 - added ReadAndLoop() method to class 'Sample' which is an extension to
953 the normal Read() method to honor the sample's looping information
954 while streaming from disk
955 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
956 'eg2_ctrl_t': replaced this huge enumeration by a structure which
957 reflects the MIDI controller number in case of an ordinary control
958 change controller (this saves a huge switch-case block in the
959 application of the library user)
960 - renamed following attributes in class 'DimensionRegion':
961 'AttenuationContol' -> 'AttenuationController',
962 'InvertAttenuationControl' -> 'InvertAttenuationController',
963 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
964 - minor fix in API documentation for method GetVelocityAttenuation() in
965 class 'DimensionRegion'
966
967 * src/RIFF.cpp, src/RIFF.h:
968 - added additional API documentation
969 - minor fix in Chunk::Read() method (only a minor efficiency issue)
