37 Version 4.3.0 (9 May 2021)
38
39 * general changes:
40 - Require at least a C++11 compliant compiler.
41 - Require some UUID generating function by underlying system.
42
43 * src/gig.cpp, src/gig.h:
44 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
45 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
46 allow to define override LFOs' wave form (e.g. saw or square instead of
47 the default wave form which was always sine in the original
48 Gigasampler/GigaStudio software).
49 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
50 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
51 move the start point horizontally of the LFOs' waves (0�� ... 360��).
52 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
53 (the original Gigasampler/GigaStudio software only had that flip phase
54 option for LFO1 and LFO2).
55 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
56 Region::UsesAnyGigFormatExtension(),
57 Instrument::UsesAnyGigFormatExtension() and
58 File::UsesAnyGigFormatExtension() (however only as private methods yet,
59 see comments on methods why).
60 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
61 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
62 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
63 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
64 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
65 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
66 (patch by Ivan Maguidhir).
67 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
68 (original patch by Ivan Maguidhir).
69 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
70 dimensions being in different order after deleting a dimension zone.
71 - Script: Generate a persistent UUID for each script.
72 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
73 accordingly added new methods to Instrument class:
74 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
75 GetScriptPatchVariable(), SetScriptPatchVariable(),
76 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
77 as child of our '3LS ' list chunk on Instrument level.
78 - Fixed undefined behaviour when modifying script slots on an instrument
79 that had been cloned and not been saved yet (e.g. unintended modification
80 of original instrument's script slots, and crash on Instrument destruction
81 due to double free of pScriptRefs).
82
83 * src/Serialization.cpp, src/Serialization.h:
84 - Fixed broken Archive(RawData) constructor which always threw an
85 Exception.
86 - Added built-in support for C++ String objects (a.k.a. std::string
87 from the STL) and bumped Srx format version to 1.1 for that reason.
88 - Fixed assertion fault on some systems if a member variable defined was
89 serialized which was declared as size_t or ssize_t data type.
90 - Added new method Archive::operation() which allows applications to
91 distinguish between serialization vs. deserialization in their
92 serialize() method implementations.
93 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
94 the STL).
95 - Member offsets are now signed and for (newly added support of) member
96 variables on the heap -1 is always used as offset instead.
97 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
98 STL).
99 - DataType: Added optional 2nd custom type name.
100 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
101 STL).
102
103 * src/helper.h:
104 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
105 function call.
106
107 * src/tools/gigdump.cpp:
108 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
109 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
110 LFO2FlipPhase and LFO3FlipPhase.
111
112 Version 4.2.0 (25 Jul 2019)
113
114 * general changes:
115 - Added MSVC build support (anonymous patch from mailing list).
116 - Introduced CMake build support (yet constrained for building with MSVC)
117 (anonymous patch from mailing list).
118 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
119 destructors. Added new virtual method DeleteChunks() to those classes
120 for this which must be explicitly called instead to remove their RIFF
121 chunks.
122 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
123 of zero; which is unsafe per se.
124 - Added C++11 "override" keyword where appropriate.
125 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
126 of their actions when not passing a progress_t callback structure.
127
128 * src/gig.cpp, src/gig.h:
129 - Fixed Doxygen API comments for enum types (currently latest Doxygen
130 [v1.8.13] only supports C comments in macro arguments expansion, but
131 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
132 the Doxygen source code, which currently also filter out new line
133 \n chars).
134 - Added new method File::CountSamples().
135 - Added new method File::CountInstruments().
136 - Fixed gig v4 files falsely being handled as v2 format
137 (patch by Ivan Maguidhir).
138 - Added gig v4 version identifier (File::VERSION_4).
139 - GIG FORMAT EXTENSION: Added attribute
140 DimensionRegion::SustainReleaseTrigger which allows to define whether
141 a sustain pedal up event shall cause a release trigger sample to be
142 played (default: don't play release trigger sample by sustain pedal).
143 - GIG FORMAT EXTENSION: Added attribute
144 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
145 regular behaviour of playing release trigger sample on MIDI note-off
146 events.
147 - Introduced support for writing extension files (.gx01, .gx02, ...)
148 (original patch by Ivan Maguidhir).
149 - Many gig classes derive now from DLS::Storage (see DLS changes below).
150 - Added File::GetRiffFile() method.
151
152 * src/DLS.cpp, src/DLS.h:
153 - File: Fixed implicitly allocated RIFF::File object never been freed.
154 - Added new abstract interface base class DLS::Storage which is derived by
155 the respective classes for implementing (the old) UpdateChunks() and the
156 new DeleteChunks() method.
157 - Added File::GetRiffFile() method.
158
159 * src/sf2.cpp, src/sf2.h:
160 - Added Sample::GetFile() method.
161 - Added File::GetRiffFile() method.
162
163 * src/Serialization.cpp, src/Serialization.h:
164 - Hide pure internal declarations from header file to avoid numerous
165 compiler warnings when building and linking against the public API.
166 - Fixed comparision logic bug
167 - Fixed memory leak in DataType::customTypeName().
168
169 * src/RIFF.cpp, src/RIFF.h:
170 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
171 caused a resource leak
172 - Avoid compiler warning when building for 32 bit windows.
173 - Added new method progress_t::subdivide().
174 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
175 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
176 allows a more fine graded control into which portions the subtasks are
177 divided to.
178
179 * src/tools/gigdump.cpp:
180 - Added command line option --instrument-names which causes only
181 instrument names and their index numbers to be printed.
182
183 Version 4.1.0 (25 Nov 2017)
184 * general changes:
185 - removed 2 GB limitation when loading a gig or DLS file
186 - using now native integer size where appropriate
187 - fixed minor issues with man pages (patch by Debian maintainer)
188 - fixed various spelling mistakes (patch by Debian maintainer)
189 - Added new "Serialization" framework (and equally named namespace)
190 which allows to serialize and deserialize native C++ objects
191 in a portable, easy and flexible way.
192 - print compiler warning if no RTTI available
193 - Fixed potential crash in command line tools gig2stereo, korg2gig,
194 korgdump and sf2extract.
195 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
196 (original patch by Paul Brossier, slightly modified).
197 - Debian: Fixed packaging error about invalid substitution variable
198 "Source-Version".
199 - Raised Debian compatibility level to Debian 9 "Stretch".
200
201 * src/gig.cpp, src/gig.h:
202 - fixed bug in Script::SetGroup: the script chunk wasn't moved
203 - fixed compilation error with clang 3.4
204 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
205 as one single monolithic gig file. In case .gig file is >= 2GB expect a
206 large monolithic file, otherwise if .gig file is < 2 GB check for
207 "extension" files (.gx01, .gx02, ...) instead.
208 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
209 if there were dimensions after the velocity dimension: it only created
210 valid velocity tables for cases of dimensions lower than the velocity
211 dimension.
212 - added new method Sample::VerifyWaveData() which allows to check whether
213 a sample had been damaged for some reason
214 - Fix: samples' CRC checksums were damaged on file structure changes.
215 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
216 - Added new method Sample::GetWaveDataCRC32Checksum().
217 - Changed default value of EG2Release (filter release time) to 60s.
218 - Instruments' default pitch bend range is now +-2 semi tones.
219 - Fixed CRC checksums being wrong sometimes.
220 - Fix: method File::AddContentOf() did not clone script groups and scripts
221 of passed original file.
222 - Added support for serializing & deserializing DimensionRegion
223 objects (and crossfade_t and leverage_ctrl_t objects).
224 - Added enum reflection API functions for retrieving enum declaration type
225 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
226 - Exception class now has a variadic constructor which allows to add
227 textual format specifiers like with printf().
228 - On unknown leverage controller exception: show precise unknown leverage
229 controller number found.
230 - Ignore invalid leverage controller types and just show a warning on the
231 console instead of throwing an exception.
232 - Added new struct eg_opt_t and new class member variable
233 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
234 extension to the gig file format, which allows to override the default
235 behavior of the first two EGs' state machines.
236 - Fixed undefined behavior when loading a gig file with invalid
237 velocity curve parameters (fixes CVE-2017-12951).
238 - Fixed undefined behavior when loading a gig file with invalid wave
239 pool index number (fixes CVE-2017-12954).
240
241 * src/DLS.cpp, src/DLS.h:
242 - Sample: wave pool offsets are now 64 bits (to allow support for files
243 larger than 4 GB).
244 - Exception class now has a variadic constructor which allows to add
245 textual format specifiers like with printf().
246
247 * src/RIFF.cpp, src/RIFF.h:
248 - added support for RIFF files larger than 4 GB, by default the required
249 internal RIFF file offset size is automatically detected (that is RIFF
250 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
251 automatically use 64 bit offsets), a particular offset size can be forced
252 with a new option added to the RIFF File constructor though
253 - when saving a modified, grown RIFF file, the temporary file size during
254 Save() operation will no longer be larger than the final grown file size
255 - Exception class now has a variadic constructor which allows to add
256 textual format specifiers like with printf().
257
258 * src/Serialization.cpp, src/Serialization.h:
259 - Archive: Added method isModified().
260 - Archive: Added method setAutoValue().
261 - Archive: Added method setIntValue().
262 - Archive: Added method setRealValue().
263 - Archive: Added method setBoolValue().
264 - Archive: Added method setEnumValue().
265 - Archive: Added method valueAsString().
266 - Archive::rawData(): Automatically re-encode new raw data stream if
267 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
268 - Object: Added method memberByUID().
269 - Object: remove() method is now protected.
270 - Archive: Added method removeMember().
271 - Archive: Added methods name() and setName().
272 - Archive: Added methods comment() and setComment().
273 - Archive: Added methods timeStampCreated(), timeStampModified(),
274 dateTimeCreated() and dateTimeModified().
275 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
276 - DataType: Implemented demangling C++ type names (for methods
277 asLongDescr() and customTypeName(bool demangle=false)).
278 - Archive::setAutoValue(): Handle human readable boolean text
279 representations like "yes", "no", "true", "false" as expected.
280 - Exception class now has a variadic constructor which allows to add
281 textual format specifiers like with printf().
282 - DataType fix: Retain backward compatibility to older versions of native
283 C++ classes/structs.
284

300 data
301 - added and implemented new parameter "--verify" which allows to check
302 the raw wave form data integrity of all samples
303 - added and implemented new parameter "--rebuild-checksums" which allows
304 to recalculate the CRC32 checksum of all samples' raw wave data and
305 rebuilding the gig file's global checksum table (i.e. in case the
306 file's checksum table was damaged)
307 - print samples' CRC32 checksums
308 - Print the new EG behavior options (eg_opt_t).
309
310 * src/tools/gigextract.cpp:
311 - Fix: if sample name contains a path separator (slash or backslash) then
312 replace them by a minus sign to avoid file system issues.
313
314 * src/tools/gig2stereo.cpp:
315 - Also merge mono sample pairs with non matching loop information if
316 argument --incompatible was given.
317
318 * packaging changes:
319 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
320 auto detect whether it (sh/c)ould output its messages in color.

355
356 * AKAI file format:
357 - Added Linux/POSIX ported version of libakai. Note that libakai is released

462 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
463
464 * src/RIFF.cpp, src/RIFF.h:
465 - bugfix: saving to the same file after the file size had been
466 increased made the file corrupt (#82)
467 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
468 is not written physically yet (#82)

470 decreased sometimes also made the file corrupt!
471 - bugfix: undefined behavior (e.g. endless loop) when opening zero
472 length files, now throws a RIFF::Exception instead (fixes bug #121)
473 - bugfix: destructor for base class RIFF::Chunk accessed members
474 of derived class RIFF::File, which is bad, and caused crashes
475 when using Visual C++
476 - bugfix: files that contain zero length RIFF lists were not read
477 correctly (fixes #127) (bug was introduced 2009-03-13)
478

484
485 * src/gig.cpp, src/gig.h:
486 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
487 applications to retrieve very superficial informations like amount of
488 instruments and their names in a very fast way
489
490 Version 3.2.0 (14 Oct 2007)
491
492 * packaging changes:
493 - added Mac OSX XCode project files (patch by Toshi Nagata)

518 - added missing parameter initalizations in sample, region and
519 instrument constructors
520 - clear unused fields when saving samples and regions
521 - fixed write support bugs: v3 dimension limits and chunksize
522 weren't saved, leverage controller of type controlchange
523 couldn't be saved, group name list chunk was placed wrong,
524 dimension region chunks also placed wrong
525 - added initialization of some fixed info strings in file and
526 instrument

536 instruments
537 - write support: improved the default values for dimension region
538 parameters
539 - more write support fixes: crossfade parameters were not saved,
540 v3 dimension limits were not correctly initialized and saved
541 when dimensions were added or deleted, v3 wave pool offsets were
542 not saved correctly
543 - write support: 24 bit samples can now be written
544 - write support: version 3 is now the default for new files
545 - more write support fixes: the 3ewg chunk is now bigger for v3,
546 dimension regions without mapped samples are now allowed, 3gnl
547 list in v3 files now always has 128 entries, several parameters
548 where incorrectly saved due to an operator precedence mistake
549 - DeleteSample now removes all references to the deleted sample
550 - AddDimension now copies all parameters from existing dimension
551 regions and also makes sure that the samplechannel dimension is
552 placed first in the list of dimensions.
553 - added method GetParent() to class 'DimensionRegion', which returns its
554 parent Region
555 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
556 unused areas
557 - added various setter methods to DimensionRegion class which take care
558 of updating lookup tables / caches.

575 - custom velocity splits now works for gig v3 files too
576 - added support for custom splits points for other dimensions than
577 velocity (gig v3 feature)
578 - added "smart midi" and "round robin keyboard" dimensions
579 - added new method File::DeleteGroupOnly() which only deletes the given
580 group but moves all its members to another group, the other method,
581 that is File::DeleteGroup() now removes not just the group, but also
582 all the samples that belong to that group
583 - fixed crash which occured on interfering File::DeleteSample() and
584 File::GetNextSample() calls (due to iterator invalidation)
585 - fixed group names which were not saved
586 - fixed group destructor which did not remove the RIFF chunk associated
587 with the group
588 - added Instrument::MoveRegion method
589 - fixed constructor for Region, which did not initialize correctly
590 when used from Instrument::AddRegion
591 - when saving, override the gig::Regions sample reference simply by
592 the region's first dimension region's sample (avoids an exception
593 when trying to save a new instrument)
594 - fixed AddDimension() method which did not fill out all mandatory
595 dimension definition fields
596
597 * src/DLS.cpp, src/DLS.h:

731 (patch by Andreas Persson)
732 - added some file format compatibility checks
733 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

788 SuSE and Fedora)
789 - fixed generation of Doxygen API documentation (now also included in
790 RPM and Debian packages)
791
792 * src/gig.cpp, src/gig.h:
793 - fixed / improved accuracy of all three velocity to volume
794 transformation functions a.k.a. 'nonlinear','linear','special'
795 (patch by Andreas Persson)
796 - denormals are filtered from the velocity to volume tables
797 - bugfix for dimension region switching (wrong handling of the release
798 trigger dimension, no bit range check for dimensions of split type
799 'split_type_bit')
800 - fixed panorama value in DimensionRegion (invalid conversion from
801 signed 7 bit to signed 8 bit)
802 - added class attribute 'Layers' to class 'gig::Region'
803 - symbol prototyping of gig::Region (fixes build failure with qsampler)
804

828
829 * general changes:
830 - various big endian specific corrections

835 - added man pages for the command line tools
836 (gigextract, gigdump, dlsdump, rifftree)
837
838 * src/gig.cpp, src/gig.h:
839 - fixed bug in decompression algorithm which caused it not to detect
840 the end of a stream
841 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
842 takes the MIDI key velocity value as an argument and returns the
843 appropriate volume factor (0.0 ... 1.0) for the sample to be played
844 back, the velocity curve transformation functions used for this are
845 only an approximation so far
846 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
847 'Sample::LoopSize' which reflected wrong values
848 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
849 measured in sample points instead of byte offset
850 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
851 'Sample::FineTune'
852 - added class attribute 'Sample::LoopSize'
853 - added method GetInstrument(uint index) to class 'File'
854 - added ReadAndLoop() method to class 'Sample' which is an extension to
855 the normal Read() method to honor the sample's looping information
856 while streaming from disk
857 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
858 'eg2_ctrl_t': replaced this huge enumeration by a structure which
859 reflects the MIDI controller number in case of an ordinary control
860 change controller (this saves a huge switch-case block in the
861 application of the library user)
862 - renamed following attributes in class 'DimensionRegion':
863 'AttenuationContol' -> 'AttenuationController',
864 'InvertAttenuationControl' -> 'InvertAttenuationController',
865 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
866 - minor fix in API documentation for method GetVelocityAttenuation() in
867 class 'DimensionRegion'
868
869 * src/RIFF.cpp, src/RIFF.h:
870 - added additional API documentation
871 - minor fix in Chunk::Read() method (only a minor efficiency issue)
872
873 * src/gigdump.cpp:
874 - added printout of samples' looping informations
875
876 Version 0.6.0 (3 Nov 2003)
877
878 * initial release
