19 schoenebeck 3623
20     * general changes:
21     - Require at least a C++11 compliant compiler.
22 schoenebeck 3723 - Require some UUID generating function by underlying system.
23 schoenebeck 3623
24     * src/gig.cpp, src/gig.h:
25     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
26     DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
27     allow to define override LFOs' wave form (e.g. saw or square instead of
28     the default wave form which was always sine in the original
29     Gigasampler/GigaStudio software).
30     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
31     DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
32     move the start point horizontally of the LFOs' waves (0�� ... 360��).
33     - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
34     (the original Gigasampler/GigaStudio software only had that flip phase
35     option for LFO1 and LFO2).
36 schoenebeck 3710 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
37     Region::UsesAnyGigFormatExtension(),
38     Instrument::UsesAnyGigFormatExtension() and
39     File::UsesAnyGigFormatExtension() (however only as private methods yet,
40     see comments on methods why).
41 schoenebeck 3645 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
42     implementations to enum vcf_type_t: vcf_type_lowpass_1p,
43     vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
44     vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
45     vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.

47     (patch by Ivan Maguidhir).
48 schoenebeck 3657 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
49     (original patch by Ivan Maguidhir).
50 schoenebeck 3720 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
51     dimensions being in different order after deleting a dimension zone.
52 schoenebeck 3723 - Script: Generate a persistent UUID for each script.
53 schoenebeck 3731 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
54     accordingly added new methods to Instrument class:
55     IsScriptPatchVariableSet(), GetScriptPatchVariables(),
56     GetScriptPatchVariable(), SetScriptPatchVariable(),
57     UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
58     as child of our '3LS ' list chunk on Instrument level.
59 schoenebeck 3799 - Fixed undefined behaviour when modifying script slots on an instrument
60     that had been cloned and not been saved yet (e.g. unintended modification
61     of original instrument's script slots, and crash on Instrument destruction
62     due to double free of pScriptRefs).
63 schoenebeck 3623
64 schoenebeck 3770 * src/Serialization.cpp, src/Serialization.h:
65     - Fixed broken Archive(RawData) constructor which always threw an
66     Exception.
67 schoenebeck 3771 - Added built-in support for C++ String objects (a.k.a. std::string
68     from the STL) and bumped Srx format version to 1.1 for that reason.
69 schoenebeck 3773 - Fixed assertion fault on some systems if a member variable defined was
70     serialized which was declared as size_t or ssize_t data type.
71 schoenebeck 3774 - Added new method Archive::operation() which allows applications to
72     distinguish between serialization vs. deserialization in their
73     serialize() method implementations.
74 schoenebeck 3775 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
75     the STL).
76     - Member offsets are now signed and for (newly added support of) member
77     variables on the heap -1 is always used as offset instead.
78 schoenebeck 3776 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
79     STL).
80 schoenebeck 3777 - DataType: Added optional 2nd custom type name.
81     - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
82     STL).
83 schoenebeck 3770
84 schoenebeck 3859 * src/helper.h:
85     - Fix compile error with GCC 9 due to ignored result value of vasprintf()
86     function call.

92    
93 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
94 schoenebeck 3392
95 schoenebeck 3476 * general changes:
96     - Added MSVC build support (anonymous patch from mailing list).
97     - Introduced CMake build support (yet constrained for building with MSVC)
98     (anonymous patch from mailing list).
99 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
100     destructors. Added new virtual method DeleteChunks() to those classes
101     for this which must be explicitly called instead to remove their RIFF
102     chunks.
103     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
104     of zero; which is unsafe per se.
105     - Added C++11 "override" keyword where appropriate.
106 schoenebeck 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
107     of their actions when not passing a progress_t callback structure.
108 schoenebeck 3476
109 schoenebeck 3398 * src/gig.cpp, src/gig.h:
110     - Fixed Doxygen API comments for enum types (currently latest Doxygen
111     [v1.8.13] only supports C comments in macro arguments expansion, but
112     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
113     the Doxygen source code, which currently also filter out new line
114     \n chars).
115 schoenebeck 3414 - Added new method File::CountSamples().
116     - Added new method File::CountInstruments().
117 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
118     (patch by Ivan Maguidhir).
119     - Added gig v4 version identifier (File::VERSION_4).
120 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
121     DimensionRegion::SustainReleaseTrigger which allows to define whether
122     a sustain pedal up event shall cause a release trigger sample to be
123     played (default: don't play release trigger sample by sustain pedal).
124 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
125     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
126     regular behaviour of playing release trigger sample on MIDI note-off
127     events.
128 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
129     (original patch by Ivan Maguidhir).
130 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).

132 schoenebeck 3398
133 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
134     - File: Fixed implicitly allocated RIFF::File object never been freed.
135 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
136     the respective classes for implementing (the old) UpdateChunks() and the
137     new DeleteChunks() method.
138 schoenebeck 3481 - Added File::GetRiffFile() method.
139 schoenebeck 3463
140 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
141     - Added Sample::GetFile() method.
142     - Added File::GetRiffFile() method.
143    
144 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
145     - Hide pure internal declarations from header file to avoid numerous
146     compiler warnings when building and linking against the public API.
147 persson 3454 - Fixed comparision logic bug
148 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
149 schoenebeck 3392
150 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
151     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
152     caused a resource leak
153 persson 3468 - Avoid compiler warning when building for 32 bit windows.
154 schoenebeck 3478 - Added new method progress_t::subdivide().
155 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
156     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
157     allows a more fine graded control into which portions the subtasks are
158     divided to.
159 schoenebeck 3412
160 schoenebeck 3425 * src/tools/gigdump.cpp:
161     - Added command line option --instrument-names which causes only
162     instrument names and their index numbers to be printed.
163    
164 schoenebeck 3370 Version 4.1.0 (25 Nov 2017)

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

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

246     - Archive: Added method valueAsString().
247     - Archive::rawData(): Automatically re-encode new raw data stream if
248     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
249 schoenebeck 3153 - Object: Added method memberByUID().
250     - Object: remove() method is now protected.
251 schoenebeck 3156 - Archive: Added method removeMember().
252     - Archive: Added methods name() and setName().
253     - Archive: Added methods comment() and setComment().
254     - Archive: Added methods timeStampCreated(), timeStampModified(),
255     dateTimeCreated() and dateTimeModified().
256 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
257 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
258     asLongDescr() and customTypeName(bool demangle=false)).
259 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
260     representations like "yes", "no", "true", "false" as expected.
261 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
262     textual format specifiers like with printf().
263 schoenebeck 3334 - DataType fix: Retain backward compatibility to older versions of native
264     C++ classes/structs.
265 schoenebeck 3150

276 persson 2836
277 schoenebeck 2923 * src/tools/gigdump.cpp:
278     - additionally print VelocityUpperLimit and DimensionUpperLimits of all
279     dimension regions
280 schoenebeck 2984 - additionally print RIFF chunk file offset and RIFF chunk size of sample
281     data
282 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
283     the raw wave form data integrity of all samples
284     - added and implemented new parameter "--rebuild-checksums" which allows
285     to recalculate the CRC32 checksum of all samples' raw wave data and
286     rebuilding the gig file's global checksum table (i.e. in case the
287     file's checksum table was damaged)
288 schoenebeck 2989 - print samples' CRC32 checksums
289 schoenebeck 3323 - Print the new EG behavior options (eg_opt_t).

295 schoenebeck 3115 * src/tools/gig2stereo.cpp:
296     - Also merge mono sample pairs with non matching loop information if
297     argument --incompatible was given.
298    
299 schoenebeck 2912 * packaging changes:
300     - Automake: set environment variable GCC_COLORS=auto to allow GCC to
301     auto detect whether it (sh/c)ould output its messages in color.
302

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