140
141 Version 4.3.0 (9 May 2021)
142
143 * general changes:
144 - Require at least a C++11 compliant compiler.
145 - Require some UUID generating function by underlying system.
146
147 * src/gig.cpp, src/gig.h:
148 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
149 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
150 allow to define override LFOs' wave form (e.g. saw or square instead of
151 the default wave form which was always sine in the original
152 Gigasampler/GigaStudio software).
153 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
154 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
155 move the start point horizontally of the LFOs' waves (0�� ... 360��).
156 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
157 (the original Gigasampler/GigaStudio software only had that flip phase
158 option for LFO1 and LFO2).
159 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
160 Region::UsesAnyGigFormatExtension(),
161 Instrument::UsesAnyGigFormatExtension() and
162 File::UsesAnyGigFormatExtension() (however only as private methods yet,
163 see comments on methods why).
164 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
165 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
166 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
167 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
168 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
169 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
170 (patch by Ivan Maguidhir).
171 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
172 (original patch by Ivan Maguidhir).
173 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
174 dimensions being in different order after deleting a dimension zone.
175 - Script: Generate a persistent UUID for each script.
176 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
177 accordingly added new methods to Instrument class:
178 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
179 GetScriptPatchVariable(), SetScriptPatchVariable(),
180 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
181 as child of our '3LS ' list chunk on Instrument level.
182 - Fixed undefined behaviour when modifying script slots on an instrument
183 that had been cloned and not been saved yet (e.g. unintended modification
184 of original instrument's script slots, and crash on Instrument destruction
185 due to double free of pScriptRefs).
186
187 * src/Serialization.cpp, src/Serialization.h:
188 - Fixed broken Archive(RawData) constructor which always threw an
189 Exception.
190 - Added built-in support for C++ String objects (a.k.a. std::string
191 from the STL) and bumped Srx format version to 1.1 for that reason.
192 - Fixed assertion fault on some systems if a member variable defined was
193 serialized which was declared as size_t or ssize_t data type.
194 - Added new method Archive::operation() which allows applications to
195 distinguish between serialization vs. deserialization in their
196 serialize() method implementations.
197 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
198 the STL).
199 - Member offsets are now signed and for (newly added support of) member
200 variables on the heap -1 is always used as offset instead.
201 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
202 STL).
203 - DataType: Added optional 2nd custom type name.
204 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
205 STL).
206
207 * src/helper.h:
208 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
209 function call.
210
211 * src/tools/gigdump.cpp:
212 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
213 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
214 LFO2FlipPhase and LFO3FlipPhase.
215
216 Version 4.2.0 (25 Jul 2019)
217
218 * general changes:
219 - Added MSVC build support (anonymous patch from mailing list).
220 - Introduced CMake build support (yet constrained for building with MSVC)
221 (anonymous patch from mailing list).
222 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
223 destructors. Added new virtual method DeleteChunks() to those classes
224 for this which must be explicitly called instead to remove their RIFF
225 chunks.
226 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
227 of zero; which is unsafe per se.
228 - Added C++11 "override" keyword where appropriate.
229 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
230 of their actions when not passing a progress_t callback structure.
231
232 * src/gig.cpp, src/gig.h:
233 - Fixed Doxygen API comments for enum types (currently latest Doxygen
234 [v1.8.13] only supports C comments in macro arguments expansion, but
235 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
236 the Doxygen source code, which currently also filter out new line
237 \n chars).
238 - Added new method File::CountSamples().
239 - Added new method File::CountInstruments().
240 - Fixed gig v4 files falsely being handled as v2 format
241 (patch by Ivan Maguidhir).
242 - Added gig v4 version identifier (File::VERSION_4).
243 - GIG FORMAT EXTENSION: Added attribute
244 DimensionRegion::SustainReleaseTrigger which allows to define whether
245 a sustain pedal up event shall cause a release trigger sample to be
246 played (default: don't play release trigger sample by sustain pedal).
247 - GIG FORMAT EXTENSION: Added attribute
248 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
249 regular behaviour of playing release trigger sample on MIDI note-off
250 events.
251 - Introduced support for writing extension files (.gx01, .gx02, ...)
252 (original patch by Ivan Maguidhir).
253 - Many gig classes derive now from DLS::Storage (see DLS changes below).
254 - Added File::GetRiffFile() method.
255
256 * src/DLS.cpp, src/DLS.h:
257 - File: Fixed implicitly allocated RIFF::File object never been freed.
258 - Added new abstract interface base class DLS::Storage which is derived by
259 the respective classes for implementing (the old) UpdateChunks() and the
260 new DeleteChunks() method.
261 - Added File::GetRiffFile() method.
262
263 * src/sf2.cpp, src/sf2.h:
264 - Added Sample::GetFile() method.
265 - Added File::GetRiffFile() method.
266
267 * src/Serialization.cpp, src/Serialization.h:
268 - Hide pure internal declarations from header file to avoid numerous
269 compiler warnings when building and linking against the public API.
270 - Fixed comparision logic bug
271 - Fixed memory leak in DataType::customTypeName().
272
273 * src/RIFF.cpp, src/RIFF.h:
274 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
275 caused a resource leak
276 - Avoid compiler warning when building for 32 bit windows.
277 - Added new method progress_t::subdivide().
278 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
279 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
280 allows a more fine graded control into which portions the subtasks are
281 divided to.
282
283 * src/tools/gigdump.cpp:
284 - Added command line option --instrument-names which causes only
285 instrument names and their index numbers to be printed.
286
287 Version 4.1.0 (25 Nov 2017)
288 * general changes:
289 - removed 2 GB limitation when loading a gig or DLS file
290 - using now native integer size where appropriate
291 - fixed minor issues with man pages (patch by Debian maintainer)
292 - fixed various spelling mistakes (patch by Debian maintainer)
293 - Added new "Serialization" framework (and equally named namespace)
294 which allows to serialize and deserialize native C++ objects
295 in a portable, easy and flexible way.
296 - print compiler warning if no RTTI available
297 - Fixed potential crash in command line tools gig2stereo, korg2gig,
298 korgdump and sf2extract.
299 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
300 (original patch by Paul Brossier, slightly modified).
301 - Debian: Fixed packaging error about invalid substitution variable
302 "Source-Version".
303 - Raised Debian compatibility level to Debian 9 "Stretch".
304
305 * src/gig.cpp, src/gig.h:
306 - fixed bug in Script::SetGroup: the script chunk wasn't moved
307 - fixed compilation error with clang 3.4
308 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
309 as one single monolithic gig file. In case .gig file is >= 2GB expect a
310 large monolithic file, otherwise if .gig file is < 2 GB check for
311 "extension" files (.gx01, .gx02, ...) instead.
312 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
313 if there were dimensions after the velocity dimension: it only created
314 valid velocity tables for cases of dimensions lower than the velocity
315 dimension.
316 - added new method Sample::VerifyWaveData() which allows to check whether
317 a sample had been damaged for some reason
318 - Fix: samples' CRC checksums were damaged on file structure changes.
319 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
320 - Added new method Sample::GetWaveDataCRC32Checksum().
321 - Changed default value of EG2Release (filter release time) to 60s.
322 - Instruments' default pitch bend range is now +-2 semi tones.
323 - Fixed CRC checksums being wrong sometimes.
324 - Fix: method File::AddContentOf() did not clone script groups and scripts
325 of passed original file.
326 - Added support for serializing & deserializing DimensionRegion
327 objects (and crossfade_t and leverage_ctrl_t objects).
328 - Added enum reflection API functions for retrieving enum declaration type
329 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
330 - Exception class now has a variadic constructor which allows to add
331 textual format specifiers like with printf().
332 - On unknown leverage controller exception: show precise unknown leverage
333 controller number found.
334 - Ignore invalid leverage controller types and just show a warning on the
335 console instead of throwing an exception.
336 - Added new struct eg_opt_t and new class member variable
337 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
338 extension to the gig file format, which allows to override the default
339 behavior of the first two EGs' state machines.
340 - Fixed undefined behavior when loading a gig file with invalid
341 velocity curve parameters (fixes CVE-2017-12951).
342 - Fixed undefined behavior when loading a gig file with invalid wave
343 pool index number (fixes CVE-2017-12954).
344
345 * src/DLS.cpp, src/DLS.h:
346 - Sample: wave pool offsets are now 64 bits (to allow support for files
347 larger than 4 GB).
348 - Exception class now has a variadic constructor which allows to add
349 textual format specifiers like with printf().
350
351 * src/RIFF.cpp, src/RIFF.h:
352 - added support for RIFF files larger than 4 GB, by default the required
353 internal RIFF file offset size is automatically detected (that is RIFF
354 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
355 automatically use 64 bit offsets), a particular offset size can be forced
356 with a new option added to the RIFF File constructor though
357 - when saving a modified, grown RIFF file, the temporary file size during
358 Save() operation will no longer be larger than the final grown file size
359 - Exception class now has a variadic constructor which allows to add
360 textual format specifiers like with printf().
361
362 * src/Serialization.cpp, src/Serialization.h:
363 - Archive: Added method isModified().
364 - Archive: Added method setAutoValue().
365 - Archive: Added method setIntValue().
366 - Archive: Added method setRealValue().
367 - Archive: Added method setBoolValue().
368 - Archive: Added method setEnumValue().
369 - Archive: Added method valueAsString().
370 - Archive::rawData(): Automatically re-encode new raw data stream if
371 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
372 - Object: Added method memberByUID().
373 - Object: remove() method is now protected.
374 - Archive: Added method removeMember().
375 - Archive: Added methods name() and setName().
376 - Archive: Added methods comment() and setComment().
377 - Archive: Added methods timeStampCreated(), timeStampModified(),
378 dateTimeCreated() and dateTimeModified().
379 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
380 - DataType: Implemented demangling C++ type names (for methods
381 asLongDescr() and customTypeName(bool demangle=false)).
382 - Archive::setAutoValue(): Handle human readable boolean text
383 representations like "yes", "no", "true", "false" as expected.
384 - Exception class now has a variadic constructor which allows to add
385 textual format specifiers like with printf().
386 - DataType fix: Retain backward compatibility to older versions of native
387 C++ classes/structs.
388
389 * src/Akai.cpp:
390 - Fixed compilation error with recent, more strict compilers.
391
392 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
393 - improved output of non-ascii characters in usage messages
394 - fixed printf format strings
395
396 * src/tools/korg2gig.cpp:
397 - fixed c++11 narrowing warnings
398 - fixed fine tuning which was not translated at all
399
400 * src/tools/gigdump.cpp:
401 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
402 dimension regions
403 - additionally print RIFF chunk file offset and RIFF chunk size of sample
404 data
405 - added and implemented new parameter "--verify" which allows to check
406 the raw wave form data integrity of all samples
407 - added and implemented new parameter "--rebuild-checksums" which allows
408 to recalculate the CRC32 checksum of all samples' raw wave data and
409 rebuilding the gig file's global checksum table (i.e. in case the
410 file's checksum table was damaged)
411 - print samples' CRC32 checksums
412 - Print the new EG behavior options (eg_opt_t).
413
414 * src/tools/gigextract.cpp:
415 - Fix: if sample name contains a path separator (slash or backslash) then
416 replace them by a minus sign to avoid file system issues.
417
418 * src/tools/gig2stereo.cpp:
419 - Also merge mono sample pairs with non matching loop information if
420 argument --incompatible was given.
421
422 * packaging changes:
423 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
424 auto detect whether it (sh/c)ould output its messages in color.
425
426 Version 4.0.0 (14 Jul 2015)
427 * general changes:

458 (.KMP and .KSF files)
459
460 * AKAI file format:
461 - Added Linux/POSIX ported version of libakai. Note that libakai is released

896 * src/gig.cpp, src/gig.h:
897 - fixed / improved accuracy of all three velocity to volume
898 transformation functions a.k.a. 'nonlinear','linear','special'
899 (patch by Andreas Persson)

906 - added class attribute 'Layers' to class 'gig::Region'
907 - symbol prototyping of gig::Region (fixes build failure with qsampler)
908

943 - fixed bug in decompression algorithm which caused it not to detect
944 the end of a stream
945 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
946 takes the MIDI key velocity value as an argument and returns the
947 appropriate volume factor (0.0 ... 1.0) for the sample to be played
948 back, the velocity curve transformation functions used for this are
949 only an approximation so far
950 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
951 'Sample::LoopSize' which reflected wrong values
952 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
953 measured in sample points instead of byte offset

955 'Sample::FineTune'
956 - added class attribute 'Sample::LoopSize'
957 - added method GetInstrument(uint index) to class 'File'

959 the normal Read() method to honor the sample's looping information
960 while streaming from disk
961 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
962 'eg2_ctrl_t': replaced this huge enumeration by a structure which
963 reflects the MIDI controller number in case of an ordinary control
964 change controller (this saves a huge switch-case block in the
965 application of the library user)
966 - renamed following attributes in class 'DimensionRegion':
967 'AttenuationContol' -> 'AttenuationController',
968 'InvertAttenuationControl' -> 'InvertAttenuationController',
969 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
970 - minor fix in API documentation for method GetVelocityAttenuation() in
971 class 'DimensionRegion'
972
973 * src/RIFF.cpp, src/RIFF.h:
974 - added additional API documentation
