38 schoenebeck 3623
39     * src/gig.cpp, src/gig.h:
40     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
41     DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
42     allow to define override LFOs' wave form (e.g. saw or square instead of
43     the default wave form which was always sine in the original
44     Gigasampler/GigaStudio software).
45     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
46     DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
47     move the start point horizontally of the LFOs' waves (0�� ... 360��).
48     - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
49     (the original Gigasampler/GigaStudio software only had that flip phase
50     option for LFO1 and LFO2).
51 schoenebeck 3710 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
52     Region::UsesAnyGigFormatExtension(),
53     Instrument::UsesAnyGigFormatExtension() and
54     File::UsesAnyGigFormatExtension() (however only as private methods yet,
55     see comments on methods why).
56 schoenebeck 3645 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
57     implementations to enum vcf_type_t: vcf_type_lowpass_1p,
58     vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
59     vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,

62     (patch by Ivan Maguidhir).
63 schoenebeck 3657 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
64     (original patch by Ivan Maguidhir).
65 schoenebeck 3720 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
66     dimensions being in different order after deleting a dimension zone.
67 schoenebeck 3723 - Script: Generate a persistent UUID for each script.
68 schoenebeck 3731 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
69     accordingly added new methods to Instrument class:
70     IsScriptPatchVariableSet(), GetScriptPatchVariables(),
71     GetScriptPatchVariable(), SetScriptPatchVariable(),
72     UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
73     as child of our '3LS ' list chunk on Instrument level.
74 schoenebeck 3799 - Fixed undefined behaviour when modifying script slots on an instrument
75     that had been cloned and not been saved yet (e.g. unintended modification
76     of original instrument's script slots, and crash on Instrument destruction
77     due to double free of pScriptRefs).
78 schoenebeck 3623
79 schoenebeck 3770 * src/Serialization.cpp, src/Serialization.h:
80     - Fixed broken Archive(RawData) constructor which always threw an
81     Exception.
82 schoenebeck 3771 - Added built-in support for C++ String objects (a.k.a. std::string
83     from the STL) and bumped Srx format version to 1.1 for that reason.
84 schoenebeck 3773 - Fixed assertion fault on some systems if a member variable defined was
85     serialized which was declared as size_t or ssize_t data type.
86 schoenebeck 3774 - Added new method Archive::operation() which allows applications to
87     distinguish between serialization vs. deserialization in their
88     serialize() method implementations.
89 schoenebeck 3775 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
90     the STL).
91     - Member offsets are now signed and for (newly added support of) member
92     variables on the heap -1 is always used as offset instead.
93 schoenebeck 3776 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
94     STL).
95 schoenebeck 3777 - DataType: Added optional 2nd custom type name.

107    
108 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
109 schoenebeck 3392
110 schoenebeck 3476 * general changes:

112     - Introduced CMake build support (yet constrained for building with MSVC)
113     (anonymous patch from mailing list).
114 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
115     destructors. Added new virtual method DeleteChunks() to those classes
116     for this which must be explicitly called instead to remove their RIFF
117     chunks.
118     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
119     of zero; which is unsafe per se.
120     - Added C++11 "override" keyword where appropriate.
121 schoenebeck 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
122     of their actions when not passing a progress_t callback structure.
123 schoenebeck 3476
124 schoenebeck 3398 * src/gig.cpp, src/gig.h:
125     - Fixed Doxygen API comments for enum types (currently latest Doxygen
126     [v1.8.13] only supports C comments in macro arguments expansion, but
127     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
128     the Doxygen source code, which currently also filter out new line
129     \n chars).
130 schoenebeck 3414 - Added new method File::CountSamples().
131     - Added new method File::CountInstruments().
132 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
133     (patch by Ivan Maguidhir).
134     - Added gig v4 version identifier (File::VERSION_4).
135 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
136     DimensionRegion::SustainReleaseTrigger which allows to define whether
137     a sustain pedal up event shall cause a release trigger sample to be
138     played (default: don't play release trigger sample by sustain pedal).
139 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
140     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
141     regular behaviour of playing release trigger sample on MIDI note-off
142     events.
143 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
144     (original patch by Ivan Maguidhir).
145 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).

150 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
151     the respective classes for implementing (the old) UpdateChunks() and the
152     new DeleteChunks() method.
153 schoenebeck 3481 - Added File::GetRiffFile() method.
154 schoenebeck 3463
155 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
156     - Added Sample::GetFile() method.
157     - Added File::GetRiffFile() method.
158    
159 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
160     - Hide pure internal declarations from header file to avoid numerous
161     compiler warnings when building and linking against the public API.
162 persson 3454 - Fixed comparision logic bug
163 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
164 schoenebeck 3392
165 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
166     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
167     caused a resource leak
168 persson 3468 - Avoid compiler warning when building for 32 bit windows.
169 schoenebeck 3478 - Added new method progress_t::subdivide().
170 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
171     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
172     allows a more fine graded control into which portions the subtasks are
173     divided to.
174 schoenebeck 3412
175 schoenebeck 3425 * src/tools/gigdump.cpp:
176     - Added command line option --instrument-names which causes only
177     instrument names and their index numbers to be printed.
178    
179 schoenebeck 3370 Version 4.1.0 (25 Nov 2017)

200 schoenebeck 2912 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
201 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
202     large monolithic file, otherwise if .gig file is < 2 GB check for
203     "extension" files (.gx01, .gx02, ...) instead.
204 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
205     if there were dimensions after the velocity dimension: it only created
206     valid velocity tables for cases of dimensions lower than the velocity
207     dimension.
208 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
209     a sample had been damaged for some reason
210     - Fix: samples' CRC checksums were damaged on file structure changes.
211 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
212     - Added new method Sample::GetWaveDataCRC32Checksum().
213 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
214 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
215 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.

217     of passed original file.
218 schoenebeck 3138 - Added support for serializing & deserializing DimensionRegion
219     objects (and crossfade_t and leverage_ctrl_t objects).
220 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
221 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
222 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
223     textual format specifiers like with printf().
224     - On unknown leverage controller exception: show precise unknown leverage
225     controller number found.
226 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
227     console instead of throwing an exception.
228 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
229 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
230     extension to the gig file format, which allows to override the default
231     behavior of the first two EGs' state machines.
232 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
233     velocity curve parameters (fixes CVE-2017-12951).
234 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
235     pool index number (fixes CVE-2017-12954).
236 schoenebeck 2909
237 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
238     - Sample: wave pool offsets are now 64 bits (to allow support for files
239     larger than 4 GB).
240 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
241     textual format specifiers like with printf().
242 persson 3454
243 schoenebeck 2912 * src/RIFF.cpp, src/RIFF.h:
244     - added support for RIFF files larger than 4 GB, by default the required
245     internal RIFF file offset size is automatically detected (that is RIFF
246     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
247     automatically use 64 bit offsets), a particular offset size can be forced
248     with a new option added to the RIFF File constructor though
249     - when saving a modified, grown RIFF file, the temporary file size during
250     Save() operation will no longer be larger than the final grown file size
251 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
252     textual format specifiers like with printf().

261     - Archive: Added method valueAsString().
262     - Archive::rawData(): Automatically re-encode new raw data stream if
263     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
264 schoenebeck 3153 - Object: Added method memberByUID().
265     - Object: remove() method is now protected.
266 schoenebeck 3156 - Archive: Added method removeMember().
267     - Archive: Added methods name() and setName().
268     - Archive: Added methods comment() and setComment().
269     - Archive: Added methods timeStampCreated(), timeStampModified(),
270     dateTimeCreated() and dateTimeModified().
271 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
272 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
273     asLongDescr() and customTypeName(bool demangle=false)).
274 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
275     representations like "yes", "no", "true", "false" as expected.
276 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
277     textual format specifiers like with printf().
278 schoenebeck 3334 - DataType fix: Retain backward compatibility to older versions of native
279     C++ classes/structs.
280 schoenebeck 3150

289     - fixed c++11 narrowing warnings
290 schoenebeck 2909 - fixed fine tuning which was not translated at all
291 persson 2836
292 schoenebeck 2923 * src/tools/gigdump.cpp:
293     - additionally print VelocityUpperLimit and DimensionUpperLimits of all
294     dimension regions
295 schoenebeck 2984 - additionally print RIFF chunk file offset and RIFF chunk size of sample
296     data
297 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
298     the raw wave form data integrity of all samples
299     - added and implemented new parameter "--rebuild-checksums" which allows
300     to recalculate the CRC32 checksum of all samples' raw wave data and
301     rebuilding the gig file's global checksum table (i.e. in case the
302     file's checksum table was damaged)
303 schoenebeck 2989 - print samples' CRC32 checksums
304 schoenebeck 3323 - Print the new EG behavior options (eg_opt_t).

778 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
779 schoenebeck 196
780     * packaging changes:
781     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
782     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
783 schoenebeck 315 - fixed man pages automake install rule (which didn't work on Mandrake,
784     SuSE and Fedora)
785     - fixed generation of Doxygen API documentation (now also included in
786     RPM and Debian packages)
787 schoenebeck 196
788 schoenebeck 231 * src/gig.cpp, src/gig.h:
789     - fixed / improved accuracy of all three velocity to volume
790 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
791     (patch by Andreas Persson)
792 schoenebeck 231 - denormals are filtered from the velocity to volume tables
793 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
794     trigger dimension, no bit range check for dimensions of split type
795     'split_type_bit')
796 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
797     signed 7 bit to signed 8 bit)
798 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
799 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
800 schoenebeck 231
801 schoenebeck 220 * src/gigextract.cpp:
802     - added support for libsndfile (if libaudiofile and libsndfile are
803     available then libsndfile is preferred)
804    
805 schoenebeck 229 * src/gigdump.cpp:
806     - added printout for dimension informations (amount, type, bits, zones)
807 schoenebeck 231 - added printout for velocity response curve parameters
808 schoenebeck 235 - added printout for crossfade definitions
809 schoenebeck 269 - added printout for panorama value for each DimensionRegion
810 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
811     Gigasampler layers
812 schoenebeck 229
813 capela 168 Version 0.7.1 (2 Jul 2004)
814    
815     * packaging changes:
816 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
817     Redhat packages
818 capela 168 - header files included on installation.
819     - autotools-generated files removed from CVS repository.
820 schoenebeck 186 - added support for generating Debian packages
821     - version of shared library can be set in configure.in
822    
823 schoenebeck 58 Version 0.7.0 (3 May 2004)
824    
825     * general changes:
826     - various big endian specific corrections
827     (successfully tested now on PPC)
828     - minor adjustments to avoid compile errors on some systems
829     (using now pow() instead of powl() and --pedantic g++ compiler switch)
830     - libtoolized the library
831     - added man pages for the command line tools
832     (gigextract, gigdump, dlsdump, rifftree)
833    
834     * src/gig.cpp, src/gig.h:
835     - fixed bug in decompression algorithm which caused it not to detect
836     the end of a stream
837     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
838     takes the MIDI key velocity value as an argument and returns the
839     appropriate volume factor (0.0 ... 1.0) for the sample to be played
840     back, the velocity curve transformation functions used for this are
841     only an approximation so far
842     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
843     'Sample::LoopSize' which reflected wrong values
844     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
845     measured in sample points instead of byte offset
846     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
847     'Sample::FineTune'
848     - added class attribute 'Sample::LoopSize'
849     - added method GetInstrument(uint index) to class 'File'
850     - added ReadAndLoop() method to class 'Sample' which is an extension to
851     the normal Read() method to honor the sample's looping information
852     while streaming from disk
853     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
854     'eg2_ctrl_t': replaced this huge enumeration by a structure which
855     reflects the MIDI controller number in case of an ordinary control
856     change controller (this saves a huge switch-case block in the
857     application of the library user)
858     - renamed following attributes in class 'DimensionRegion':
859     'AttenuationContol' -> 'AttenuationController',
860     'InvertAttenuationControl' -> 'InvertAttenuationController',
861     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
862     - minor fix in API documentation for method GetVelocityAttenuation() in
863     class 'DimensionRegion'
864    
865     * src/RIFF.cpp, src/RIFF.h:
866     - added additional API documentation
867     - minor fix in Chunk::Read() method (only a minor efficiency issue)
868    
869     * src/gigdump.cpp:
870     - added printout of samples' looping informations
871    
872 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
873    
874     * initial release
