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

316 of passed original file.
317 - Added support for serializing & deserializing DimensionRegion
318 objects (and crossfade_t and leverage_ctrl_t objects).
319 - Added enum reflection API functions for retrieving enum declaration type
320 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
321 - Exception class now has a variadic constructor which allows to add
322 textual format specifiers like with printf().
323 - On unknown leverage controller exception: show precise unknown leverage
324 controller number found.
325 - Ignore invalid leverage controller types and just show a warning on the
326 console instead of throwing an exception.
327 - Added new struct eg_opt_t and new class member variable
328 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
329 extension to the gig file format, which allows to override the default
330 behavior of the first two EGs' state machines.
331 - Fixed undefined behavior when loading a gig file with invalid
332 velocity curve parameters (fixes CVE-2017-12951).
333 - Fixed undefined behavior when loading a gig file with invalid wave
334 pool index number (fixes CVE-2017-12954).
335
336 * src/DLS.cpp, src/DLS.h:
337 - Sample: wave pool offsets are now 64 bits (to allow support for files
338 larger than 4 GB).
339 - Exception class now has a variadic constructor which allows to add
340 textual format specifiers like with printf().
341
342 * src/RIFF.cpp, src/RIFF.h:
343 - added support for RIFF files larger than 4 GB, by default the required
344 internal RIFF file offset size is automatically detected (that is RIFF
345 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
346 automatically use 64 bit offsets), a particular offset size can be forced
347 with a new option added to the RIFF File constructor though
348 - when saving a modified, grown RIFF file, the temporary file size during
349 Save() operation will no longer be larger than the final grown file size
350 - Exception class now has a variadic constructor which allows to add
351 textual format specifiers like with printf().
352
353 * src/Serialization.cpp, src/Serialization.h:
354 - Archive: Added method isModified().
355 - Archive: Added method setAutoValue().
356 - Archive: Added method setIntValue().
357 - Archive: Added method setRealValue().
358 - Archive: Added method setBoolValue().
359 - Archive: Added method setEnumValue().
360 - Archive: Added method valueAsString().
361 - Archive::rawData(): Automatically re-encode new raw data stream if
362 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
363 - Object: Added method memberByUID().
364 - Object: remove() method is now protected.
365 - Archive: Added method removeMember().
366 - Archive: Added methods name() and setName().
367 - Archive: Added methods comment() and setComment().
368 - Archive: Added methods timeStampCreated(), timeStampModified(),
369 dateTimeCreated() and dateTimeModified().
370 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
371 - DataType: Implemented demangling C++ type names (for methods
372 asLongDescr() and customTypeName(bool demangle=false)).
373 - Archive::setAutoValue(): Handle human readable boolean text
374 representations like "yes", "no", "true", "false" as expected.
375 - Exception class now has a variadic constructor which allows to add
376 textual format specifiers like with printf().
377 - DataType fix: Retain backward compatibility to older versions of native
378 C++ classes/structs.
379
380 * src/Akai.cpp:
381 - Fixed compilation error with recent, more strict compilers.
382
383 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
384 - improved output of non-ascii characters in usage messages
385 - fixed printf format strings
386
387 * src/tools/korg2gig.cpp:
388 - fixed c++11 narrowing warnings

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

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

897 - added class attribute 'Layers' to class 'gig::Region'
898 - symbol prototyping of gig::Region (fixes build failure with qsampler)
899

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