15 Version 4.3.0 (9 May 2021)
16
17 * general changes:
18 - Require at least a C++11 compliant compiler.
19 - Require some UUID generating function by underlying system.
20
21 * src/gig.cpp, src/gig.h:
22 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
23 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
24 allow to define override LFOs' wave form (e.g. saw or square instead of
25 the default wave form which was always sine in the original
26 Gigasampler/GigaStudio software).
27 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
28 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
29 move the start point horizontally of the LFOs' waves (0�� ... 360��).
30 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
31 (the original Gigasampler/GigaStudio software only had that flip phase
32 option for LFO1 and LFO2).
33 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
34 Region::UsesAnyGigFormatExtension(),
35 Instrument::UsesAnyGigFormatExtension() and
36 File::UsesAnyGigFormatExtension() (however only as private methods yet,
37 see comments on methods why).
38 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
39 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
40 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
41 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
42 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
43 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
44 (patch by Ivan Maguidhir).
45 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
46 (original patch by Ivan Maguidhir).
47 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
48 dimensions being in different order after deleting a dimension zone.
49 - Script: Generate a persistent UUID for each script.
50 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
51 accordingly added new methods to Instrument class:
52 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
53 GetScriptPatchVariable(), SetScriptPatchVariable(),
54 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
55 as child of our '3LS ' list chunk on Instrument level.
56 - Fixed undefined behaviour when modifying script slots on an instrument
57 that had been cloned and not been saved yet (e.g. unintended modification
58 of original instrument's script slots, and crash on Instrument destruction
59 due to double free of pScriptRefs).
60
61 * src/Serialization.cpp, src/Serialization.h:
62 - Fixed broken Archive(RawData) constructor which always threw an
63 Exception.
64 - Added built-in support for C++ String objects (a.k.a. std::string
65 from the STL) and bumped Srx format version to 1.1 for that reason.
66 - Fixed assertion fault on some systems if a member variable defined was
67 serialized which was declared as size_t or ssize_t data type.
68 - Added new method Archive::operation() which allows applications to
69 distinguish between serialization vs. deserialization in their
70 serialize() method implementations.
71 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
72 the STL).
73 - Member offsets are now signed and for (newly added support of) member
74 variables on the heap -1 is always used as offset instead.
75 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
76 STL).
77 - DataType: Added optional 2nd custom type name.
78 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
79 STL).
80
81 * src/helper.h:
82 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
83 function call.
84
85 * src/tools/gigdump.cpp:
86 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
87 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
88 LFO2FlipPhase and LFO3FlipPhase.
89
90 Version 4.2.0 (25 Jul 2019)
91
92 * general changes:
93 - Added MSVC build support (anonymous patch from mailing list).
94 - Introduced CMake build support (yet constrained for building with MSVC)
95 (anonymous patch from mailing list).
96 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
97 destructors. Added new virtual method DeleteChunks() to those classes
98 for this which must be explicitly called instead to remove their RIFF
99 chunks.
100 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
101 of zero; which is unsafe per se.
102 - Added C++11 "override" keyword where appropriate.
103 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
104 of their actions when not passing a progress_t callback structure.
105
106 * src/gig.cpp, src/gig.h:
107 - Fixed Doxygen API comments for enum types (currently latest Doxygen
108 [v1.8.13] only supports C comments in macro arguments expansion, but
109 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
110 the Doxygen source code, which currently also filter out new line
111 \n chars).
112 - Added new method File::CountSamples().
113 - Added new method File::CountInstruments().
114 - Fixed gig v4 files falsely being handled as v2 format
115 (patch by Ivan Maguidhir).
116 - Added gig v4 version identifier (File::VERSION_4).
117 - GIG FORMAT EXTENSION: Added attribute
118 DimensionRegion::SustainReleaseTrigger which allows to define whether
119 a sustain pedal up event shall cause a release trigger sample to be
120 played (default: don't play release trigger sample by sustain pedal).
121 - GIG FORMAT EXTENSION: Added attribute
122 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
123 regular behaviour of playing release trigger sample on MIDI note-off
124 events.
125 - Introduced support for writing extension files (.gx01, .gx02, ...)
126 (original patch by Ivan Maguidhir).
127 - Many gig classes derive now from DLS::Storage (see DLS changes below).
128 - Added File::GetRiffFile() method.
129
130 * src/DLS.cpp, src/DLS.h:
131 - File: Fixed implicitly allocated RIFF::File object never been freed.
132 - Added new abstract interface base class DLS::Storage which is derived by
133 the respective classes for implementing (the old) UpdateChunks() and the
134 new DeleteChunks() method.
135 - Added File::GetRiffFile() method.
136
137 * src/sf2.cpp, src/sf2.h:
138 - Added Sample::GetFile() method.
139 - Added File::GetRiffFile() method.
140
141 * src/Serialization.cpp, src/Serialization.h:
142 - Hide pure internal declarations from header file to avoid numerous
143 compiler warnings when building and linking against the public API.
144 - Fixed comparision logic bug
145 - Fixed memory leak in DataType::customTypeName().
146
147 * src/RIFF.cpp, src/RIFF.h:
148 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
149 caused a resource leak
150 - Avoid compiler warning when building for 32 bit windows.
151 - Added new method progress_t::subdivide().
152 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
153 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
154 allows a more fine graded control into which portions the subtasks are
155 divided to.
156
157 * src/tools/gigdump.cpp:
158 - Added command line option --instrument-names which causes only
159 instrument names and their index numbers to be printed.
160
161 Version 4.1.0 (25 Nov 2017)
162 * general changes:
163 - removed 2 GB limitation when loading a gig or DLS file
164 - using now native integer size where appropriate
165 - fixed minor issues with man pages (patch by Debian maintainer)
166 - fixed various spelling mistakes (patch by Debian maintainer)
167 - Added new "Serialization" framework (and equally named namespace)
168 which allows to serialize and deserialize native C++ objects
169 in a portable, easy and flexible way.
170 - print compiler warning if no RTTI available
171 - Fixed potential crash in command line tools gig2stereo, korg2gig,
172 korgdump and sf2extract.
173 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
174 (original patch by Paul Brossier, slightly modified).
175 - Debian: Fixed packaging error about invalid substitution variable
176 "Source-Version".
177 - Raised Debian compatibility level to Debian 9 "Stretch".
178
179 * src/gig.cpp, src/gig.h:
180 - fixed bug in Script::SetGroup: the script chunk wasn't moved
181 - fixed compilation error with clang 3.4
182 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
183 as one single monolithic gig file. In case .gig file is >= 2GB expect a
184 large monolithic file, otherwise if .gig file is < 2 GB check for
185 "extension" files (.gx01, .gx02, ...) instead.
186 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
187 if there were dimensions after the velocity dimension: it only created
188 valid velocity tables for cases of dimensions lower than the velocity
189 dimension.
190 - added new method Sample::VerifyWaveData() which allows to check whether
191 a sample had been damaged for some reason
192 - Fix: samples' CRC checksums were damaged on file structure changes.
193 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
194 - Added new method Sample::GetWaveDataCRC32Checksum().
195 - Changed default value of EG2Release (filter release time) to 60s.
196 - Instruments' default pitch bend range is now +-2 semi tones.
197 - Fixed CRC checksums being wrong sometimes.
198 - Fix: method File::AddContentOf() did not clone script groups and scripts
199 of passed original file.
200 - Added support for serializing & deserializing DimensionRegion
201 objects (and crossfade_t and leverage_ctrl_t objects).
202 - Added enum reflection API functions for retrieving enum declaration type
203 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
204 - Exception class now has a variadic constructor which allows to add
205 textual format specifiers like with printf().
206 - On unknown leverage controller exception: show precise unknown leverage
207 controller number found.
208 - Ignore invalid leverage controller types and just show a warning on the
209 console instead of throwing an exception.
210 - Added new struct eg_opt_t and new class member variable
211 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
212 extension to the gig file format, which allows to override the default
213 behavior of the first two EGs' state machines.
214 - Fixed undefined behavior when loading a gig file with invalid
215 velocity curve parameters (fixes CVE-2017-12951).
216 - Fixed undefined behavior when loading a gig file with invalid wave
217 pool index number (fixes CVE-2017-12954).
218
219 * src/DLS.cpp, src/DLS.h:
220 - Sample: wave pool offsets are now 64 bits (to allow support for files
221 larger than 4 GB).
222 - Exception class now has a variadic constructor which allows to add
223 textual format specifiers like with printf().
224
225 * src/RIFF.cpp, src/RIFF.h:
226 - added support for RIFF files larger than 4 GB, by default the required
227 internal RIFF file offset size is automatically detected (that is RIFF
228 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
229 automatically use 64 bit offsets), a particular offset size can be forced
230 with a new option added to the RIFF File constructor though
231 - when saving a modified, grown RIFF file, the temporary file size during
232 Save() operation will no longer be larger than the final grown file size
233 - Exception class now has a variadic constructor which allows to add
234 textual format specifiers like with printf().
235
236 * src/Serialization.cpp, src/Serialization.h:
237 - Archive: Added method isModified().
238 - Archive: Added method setAutoValue().
239 - Archive: Added method setIntValue().
240 - Archive: Added method setRealValue().
241 - Archive: Added method setBoolValue().
242 - Archive: Added method setEnumValue().
243 - Archive: Added method valueAsString().
244 - Archive::rawData(): Automatically re-encode new raw data stream if
245 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
246 - Object: Added method memberByUID().
247 - Object: remove() method is now protected.
248 - Archive: Added method removeMember().
249 - Archive: Added methods name() and setName().
250 - Archive: Added methods comment() and setComment().
251 - Archive: Added methods timeStampCreated(), timeStampModified(),
252 dateTimeCreated() and dateTimeModified().
253 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
254 - DataType: Implemented demangling C++ type names (for methods
255 asLongDescr() and customTypeName(bool demangle=false)).
256 - Archive::setAutoValue(): Handle human readable boolean text
257 representations like "yes", "no", "true", "false" as expected.
258 - Exception class now has a variadic constructor which allows to add
259 textual format specifiers like with printf().
260 - DataType fix: Retain backward compatibility to older versions of native
261 C++ classes/structs.
262
263 * src/Akai.cpp:
264 - Fixed compilation error with recent, more strict compilers.
265
266 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
267 - improved output of non-ascii characters in usage messages

275 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
276 dimension regions
277 - additionally print RIFF chunk file offset and RIFF chunk size of sample
278 data
279 - added and implemented new parameter "--verify" which allows to check
280 the raw wave form data integrity of all samples
281 - added and implemented new parameter "--rebuild-checksums" which allows
282 to recalculate the CRC32 checksum of all samples' raw wave data and
283 rebuilding the gig file's global checksum table (i.e. in case the
284 file's checksum table was damaged)
285 - print samples' CRC32 checksums
286 - Print the new EG behavior options (eg_opt_t).
287
288 * src/tools/gigextract.cpp:
289 - Fix: if sample name contains a path separator (slash or backslash) then
290 replace them by a minus sign to avoid file system issues.
291
292 * src/tools/gig2stereo.cpp:
293 - Also merge mono sample pairs with non matching loop information if
294 argument --incompatible was given.
295
296 * packaging changes:
297 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
298 auto detect whether it (sh/c)ould output its messages in color.

333
334 * AKAI file format:
335 - Added Linux/POSIX ported version of libakai. Note that libakai is released

378 of instruments within the same gig file.
379

410 one allows to move the subchunk from the current list to another list
411 - POSIX: only assume -1 result value as error on open() calls
412 - POSIX: show operating system's error reason if opening a file failed
413 - Added support for custom progress notification while saving to RIFF file.

416 - Cleanup of an old DLL binary backward compatibility hack.
417
418 * src/gigextract.cpp:
419 - export sample loop, unity note and fine tune with libsndfile
420
421 * src/riftree.cpp:
422 - added more command line options for being able to also dump other kind

440 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
441
442 * src/RIFF.cpp, src/RIFF.h:
443 - bugfix: saving to the same file after the file size had been
444 increased made the file corrupt (#82)
445 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
446 is not written physically yet (#82)
447 - bugfix: saving to the same file after the file size had been

450 length files, now throws a RIFF::Exception instead (fixes bug #121)
451 - bugfix: destructor for base class RIFF::Chunk accessed members
452 of derived class RIFF::File, which is bad, and caused crashes
453 when using Visual C++
454 - bugfix: files that contain zero length RIFF lists were not read
455 correctly (fixes #127) (bug was introduced 2009-03-13)

481 lengths can be specified for each INFO chunk
482 - added Resource::GenerateDLSID function
483 - write support fix: allow regions without mapped samples

497 instrument constructors
498 - clear unused fields when saving samples and regions
499 - fixed write support bugs: v3 dimension limits and chunksize

514 instruments
515 - write support: improved the default values for dimension region
516 parameters
517 - more write support fixes: crossfade parameters were not saved,
518 v3 dimension limits were not correctly initialized and saved
519 when dimensions were added or deleted, v3 wave pool offsets were
520 not saved correctly
521 - write support: 24 bit samples can now be written
522 - write support: version 3 is now the default for new files
523 - more write support fixes: the 3ewg chunk is now bigger for v3,

525 list in v3 files now always has 128 entries, several parameters
526 where incorrectly saved due to an operator precedence mistake
527 - DeleteSample now removes all references to the deleted sample
528 - AddDimension now copies all parameters from existing dimension
529 regions and also makes sure that the samplechannel dimension is
530 placed first in the list of dimensions.
531 - added method GetParent() to class 'DimensionRegion', which returns its
532 parent Region
533 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
534 unused areas
535 - added various setter methods to DimensionRegion class which take care
536 of updating lookup tables / caches.

554 - added support for custom splits points for other dimensions than
555 velocity (gig v3 feature)
556 - added "smart midi" and "round robin keyboard" dimensions
557 - added new method File::DeleteGroupOnly() which only deletes the given
558 group but moves all its members to another group, the other method,
559 that is File::DeleteGroup() now removes not just the group, but also
560 all the samples that belong to that group
561 - fixed crash which occured on interfering File::DeleteSample() and
562 File::GetNextSample() calls (due to iterator invalidation)

565 with the group
566 - added Instrument::MoveRegion method
567 - fixed constructor for Region, which did not initialize correctly
568 when used from Instrument::AddRegion
569 - when saving, override the gig::Regions sample reference simply by
570 the region's first dimension region's sample (avoids an exception
571 when trying to save a new instrument)

573 dimension definition fields
574
575 * src/DLS.cpp, src/DLS.h:

709 (patch by Andreas Persson)
710 - added some file format compatibility checks
711 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

764 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
765 - fixed man pages automake install rule (which didn't work on Mandrake,
766 SuSE and Fedora)
767 - fixed generation of Doxygen API documentation (now also included in
768 RPM and Debian packages)
769
770 * src/gig.cpp, src/gig.h:
771 - fixed / improved accuracy of all three velocity to volume
772 transformation functions a.k.a. 'nonlinear','linear','special'
773 (patch by Andreas Persson)
774 - denormals are filtered from the velocity to volume tables
775 - bugfix for dimension region switching (wrong handling of the release
776 trigger dimension, no bit range check for dimensions of split type
777 'split_type_bit')
778 - fixed panorama value in DimensionRegion (invalid conversion from
779 signed 7 bit to signed 8 bit)
780 - added class attribute 'Layers' to class 'gig::Region'
781 - symbol prototyping of gig::Region (fixes build failure with qsampler)
782
783 * src/gigextract.cpp:

798 - added libgig.spec and libgig.pc package configurations for generating
799 Redhat packages
800 - header files included on installation.
801 - autotools-generated files removed from CVS repository.
802 - added support for generating Debian packages
803 - version of shared library can be set in configure.in
804
805 Version 0.7.0 (3 May 2004)
806
807 * general changes:
808 - various big endian specific corrections
809 (successfully tested now on PPC)
810 - minor adjustments to avoid compile errors on some systems
811 (using now pow() instead of powl() and --pedantic g++ compiler switch)
812 - libtoolized the library
813 - added man pages for the command line tools
814 (gigextract, gigdump, dlsdump, rifftree)
815
816 * src/gig.cpp, src/gig.h:
817 - fixed bug in decompression algorithm which caused it not to detect
818 the end of a stream
819 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
820 takes the MIDI key velocity value as an argument and returns the
821 appropriate volume factor (0.0 ... 1.0) for the sample to be played
822 back, the velocity curve transformation functions used for this are
823 only an approximation so far
824 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
825 'Sample::LoopSize' which reflected wrong values
826 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
827 measured in sample points instead of byte offset
828 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
829 'Sample::FineTune'
830 - added class attribute 'Sample::LoopSize'
831 - added method GetInstrument(uint index) to class 'File'
832 - added ReadAndLoop() method to class 'Sample' which is an extension to
833 the normal Read() method to honor the sample's looping information
834 while streaming from disk
835 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
836 'eg2_ctrl_t': replaced this huge enumeration by a structure which
837 reflects the MIDI controller number in case of an ordinary control
838 change controller (this saves a huge switch-case block in the
839 application of the library user)
840 - renamed following attributes in class 'DimensionRegion':
841 'AttenuationContol' -> 'AttenuationController',
842 'InvertAttenuationControl' -> 'InvertAttenuationController',
843 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
844 - minor fix in API documentation for method GetVelocityAttenuation() in
845 class 'DimensionRegion'
846
847 * src/RIFF.cpp, src/RIFF.h:
848 - added additional API documentation
849 - minor fix in Chunk::Read() method (only a minor efficiency issue)
850
851 * src/gigdump.cpp:
852 - added printout of samples' looping informations
853
854 Version 0.6.0 (3 Nov 2003)
855
856 * initial release
