1 Version SVN trunk (?)
2
3 * src/SF.cpp, src/SF.h:
4 - File::DeleteInstrument(): Fix clang sanatizer warning.
5
6 * src/RIFF.cpp, src/RIFF.h:
7 - Chunk::LoadChunkData(): Fix clang sanatizer warning.
8
9 Version 4.3.0 (9 May 2021)
10
11 * general changes:
12 - Require at least a C++11 compliant compiler.
13 - Require some UUID generating function by underlying system.
14
15 * src/gig.cpp, src/gig.h:
16 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
17 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
18 allow to define override LFOs' wave form (e.g. saw or square instead of
19 the default wave form which was always sine in the original
20 Gigasampler/GigaStudio software).
21 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
22 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
23 move the start point horizontally of the LFOs' waves (0° ... 360°).
24 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
25 (the original Gigasampler/GigaStudio software only had that flip phase
26 option for LFO1 and LFO2).
27 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
28 Region::UsesAnyGigFormatExtension(),
29 Instrument::UsesAnyGigFormatExtension() and
30 File::UsesAnyGigFormatExtension() (however only as private methods yet,
31 see comments on methods why).
32 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
33 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
34 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
35 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
36 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
37 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
38 (patch by Ivan Maguidhir).
39 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
40 (original patch by Ivan Maguidhir).
41 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
42 dimensions being in different order after deleting a dimension zone.
43 - Script: Generate a persistent UUID for each script.
44 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
45 accordingly added new methods to Instrument class:
46 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
47 GetScriptPatchVariable(), SetScriptPatchVariable(),
48 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
49 as child of our '3LS ' list chunk on Instrument level.
50 - Fixed undefined behaviour when modifying script slots on an instrument
51 that had been cloned and not been saved yet (e.g. unintended modification
52 of original instrument's script slots, and crash on Instrument destruction
53 due to double free of pScriptRefs).
54
55 * src/Serialization.cpp, src/Serialization.h:
56 - Fixed broken Archive(RawData) constructor which always threw an
57 Exception.
58 - Added built-in support for C++ String objects (a.k.a. std::string
59 from the STL) and bumped Srx format version to 1.1 for that reason.
60 - Fixed assertion fault on some systems if a member variable defined was
61 serialized which was declared as size_t or ssize_t data type.
62 - Added new method Archive::operation() which allows applications to
63 distinguish between serialization vs. deserialization in their
64 serialize() method implementations.
65 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
66 the STL).
67 - Member offsets are now signed and for (newly added support of) member
68 variables on the heap -1 is always used as offset instead.
69 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
70 STL).
71 - DataType: Added optional 2nd custom type name.
72 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
73 STL).
74
75 * src/helper.h:
76 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
77 function call.
78
79 * src/tools/gigdump.cpp:
80 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
81 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
82 LFO2FlipPhase and LFO3FlipPhase.
83
84 Version 4.2.0 (25 Jul 2019)
85
86 * general changes:
87 - Added MSVC build support (anonymous patch from mailing list).
88 - Introduced CMake build support (yet constrained for building with MSVC)
89 (anonymous patch from mailing list).
90 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
91 destructors. Added new virtual method DeleteChunks() to those classes
92 for this which must be explicitly called instead to remove their RIFF
93 chunks.
94 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
95 of zero; which is unsafe per se.
96 - Added C++11 "override" keyword where appropriate.
97 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
98 of their actions when not passing a progress_t callback structure.
99
100 * src/gig.cpp, src/gig.h:
101 - Fixed Doxygen API comments for enum types (currently latest Doxygen
102 [v1.8.13] only supports C comments in macro arguments expansion, but
103 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
104 the Doxygen source code, which currently also filter out new line
105 \n chars).
106 - Added new method File::CountSamples().
107 - Added new method File::CountInstruments().
108 - Fixed gig v4 files falsely being handled as v2 format
109 (patch by Ivan Maguidhir).
110 - Added gig v4 version identifier (File::VERSION_4).
111 - GIG FORMAT EXTENSION: Added attribute
112 DimensionRegion::SustainReleaseTrigger which allows to define whether
113 a sustain pedal up event shall cause a release trigger sample to be
114 played (default: don't play release trigger sample by sustain pedal).
115 - GIG FORMAT EXTENSION: Added attribute
116 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
117 regular behaviour of playing release trigger sample on MIDI note-off
118 events.
119 - Introduced support for writing extension files (.gx01, .gx02, ...)
120 (original patch by Ivan Maguidhir).
121 - Many gig classes derive now from DLS::Storage (see DLS changes below).
122 - Added File::GetRiffFile() method.
123
124 * src/DLS.cpp, src/DLS.h:
125 - File: Fixed implicitly allocated RIFF::File object never been freed.
126 - Added new abstract interface base class DLS::Storage which is derived by
127 the respective classes for implementing (the old) UpdateChunks() and the
128 new DeleteChunks() method.
129 - Added File::GetRiffFile() method.
130
131 * src/sf2.cpp, src/sf2.h:
132 - Added Sample::GetFile() method.
133 - Added File::GetRiffFile() method.
134
135 * src/Serialization.cpp, src/Serialization.h:
136 - Hide pure internal declarations from header file to avoid numerous
137 compiler warnings when building and linking against the public API.
138 - Fixed comparision logic bug
139 - Fixed memory leak in DataType::customTypeName().
140
141 * src/RIFF.cpp, src/RIFF.h:
142 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
143 caused a resource leak
144 - Avoid compiler warning when building for 32 bit windows.
145 - Added new method progress_t::subdivide().
146 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
147 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
148 allows a more fine graded control into which portions the subtasks are
149 divided to.
150
151 * src/tools/gigdump.cpp:
152 - Added command line option --instrument-names which causes only
153 instrument names and their index numbers to be printed.
154
155 Version 4.1.0 (25 Nov 2017)
156 * general changes:
157 - removed 2 GB limitation when loading a gig or DLS file
158 - using now native integer size where appropriate
159 - fixed minor issues with man pages (patch by Debian maintainer)
160 - fixed various spelling mistakes (patch by Debian maintainer)
161 - Added new "Serialization" framework (and equally named namespace)
162 which allows to serialize and deserialize native C++ objects
163 in a portable, easy and flexible way.
164 - print compiler warning if no RTTI available
165 - Fixed potential crash in command line tools gig2stereo, korg2gig,
166 korgdump and sf2extract.
167 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
168 (original patch by Paul Brossier, slightly modified).
169 - Debian: Fixed packaging error about invalid substitution variable
170 "Source-Version".
171 - Raised Debian compatibility level to Debian 9 "Stretch".
172
173 * src/gig.cpp, src/gig.h:
174 - fixed bug in Script::SetGroup: the script chunk wasn't moved
175 - fixed compilation error with clang 3.4
176 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
177 as one single monolithic gig file. In case .gig file is >= 2GB expect a
178 large monolithic file, otherwise if .gig file is < 2 GB check for
179 "extension" files (.gx01, .gx02, ...) instead.
180 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
181 if there were dimensions after the velocity dimension: it only created
182 valid velocity tables for cases of dimensions lower than the velocity
183 dimension.
184 - added new method Sample::VerifyWaveData() which allows to check whether
185 a sample had been damaged for some reason
186 - Fix: samples' CRC checksums were damaged on file structure changes.
187 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
188 - Added new method Sample::GetWaveDataCRC32Checksum().
189 - Changed default value of EG2Release (filter release time) to 60s.
190 - Instruments' default pitch bend range is now +-2 semi tones.
191 - Fixed CRC checksums being wrong sometimes.
192 - Fix: method File::AddContentOf() did not clone script groups and scripts
193 of passed original file.
194 - Added support for serializing & deserializing DimensionRegion
195 objects (and crossfade_t and leverage_ctrl_t objects).
196 - Added enum reflection API functions for retrieving enum declaration type
197 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
198 - Exception class now has a variadic constructor which allows to add
199 textual format specifiers like with printf().
200 - On unknown leverage controller exception: show precise unknown leverage
201 controller number found.
202 - Ignore invalid leverage controller types and just show a warning on the
203 console instead of throwing an exception.
204 - Added new struct eg_opt_t and new class member variable
205 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
206 extension to the gig file format, which allows to override the default
207 behavior of the first two EGs' state machines.
208 - Fixed undefined behavior when loading a gig file with invalid
209 velocity curve parameters (fixes CVE-2017-12951).
210 - Fixed undefined behavior when loading a gig file with invalid wave
211 pool index number (fixes CVE-2017-12954).
212
213 * src/DLS.cpp, src/DLS.h:
214 - Sample: wave pool offsets are now 64 bits (to allow support for files
215 larger than 4 GB).
216 - Exception class now has a variadic constructor which allows to add
217 textual format specifiers like with printf().
218
219 * src/RIFF.cpp, src/RIFF.h:
220 - added support for RIFF files larger than 4 GB, by default the required
221 internal RIFF file offset size is automatically detected (that is RIFF
222 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
223 automatically use 64 bit offsets), a particular offset size can be forced
224 with a new option added to the RIFF File constructor though
225 - when saving a modified, grown RIFF file, the temporary file size during
226 Save() operation will no longer be larger than the final grown file size
227 - Exception class now has a variadic constructor which allows to add
228 textual format specifiers like with printf().
229
230 * src/Serialization.cpp, src/Serialization.h:
231 - Archive: Added method isModified().
232 - Archive: Added method setAutoValue().
233 - Archive: Added method setIntValue().
234 - Archive: Added method setRealValue().
235 - Archive: Added method setBoolValue().
236 - Archive: Added method setEnumValue().
237 - Archive: Added method valueAsString().
238 - Archive::rawData(): Automatically re-encode new raw data stream if
239 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
240 - Object: Added method memberByUID().
241 - Object: remove() method is now protected.
242 - Archive: Added method removeMember().
243 - Archive: Added methods name() and setName().
244 - Archive: Added methods comment() and setComment().
245 - Archive: Added methods timeStampCreated(), timeStampModified(),
246 dateTimeCreated() and dateTimeModified().
247 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
248 - DataType: Implemented demangling C++ type names (for methods
249 asLongDescr() and customTypeName(bool demangle=false)).
250 - Archive::setAutoValue(): Handle human readable boolean text
251 representations like "yes", "no", "true", "false" as expected.
252 - Exception class now has a variadic constructor which allows to add
253 textual format specifiers like with printf().
254 - DataType fix: Retain backward compatibility to older versions of native
255 C++ classes/structs.
256
257 * src/Akai.cpp:
258 - Fixed compilation error with recent, more strict compilers.
259
260 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
261 - improved output of non-ascii characters in usage messages

272 data
273 - added and implemented new parameter "--verify" which allows to check
274 the raw wave form data integrity of all samples
275 - added and implemented new parameter "--rebuild-checksums" which allows
276 to recalculate the CRC32 checksum of all samples' raw wave data and
277 rebuilding the gig file's global checksum table (i.e. in case the
278 file's checksum table was damaged)
279 - print samples' CRC32 checksums
280 - Print the new EG behavior options (eg_opt_t).
281
282 * src/tools/gigextract.cpp:
283 - Fix: if sample name contains a path separator (slash or backslash) then
284 replace them by a minus sign to avoid file system issues.
285
286 * src/tools/gig2stereo.cpp:
287 - Also merge mono sample pairs with non matching loop information if
288 argument --incompatible was given.
289

327
328 * AKAI file format:
329 - Added Linux/POSIX ported version of libakai. Note that libakai is released

372 of instruments within the same gig file.
373

410 - Cleanup of an old DLL binary backward compatibility hack.
411
412 * src/gigextract.cpp:
413 - export sample loop, unity note and fine tune with libsndfile

434 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
435
436 * src/RIFF.cpp, src/RIFF.h:
437 - bugfix: saving to the same file after the file size had been
438 increased made the file corrupt (#82)
439 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
440 is not written physically yet (#82)
441 - bugfix: saving to the same file after the file size had been

444 length files, now throws a RIFF::Exception instead (fixes bug #121)
445 - bugfix: destructor for base class RIFF::Chunk accessed members
446 of derived class RIFF::File, which is bad, and caused crashes
447 when using Visual C++

490 - added missing parameter initalizations in sample, region and
491 instrument constructors
492 - clear unused fields when saving samples and regions
493 - fixed write support bugs: v3 dimension limits and chunksize

496 dimension region chunks also placed wrong
497 - added initialization of some fixed info strings in file and
498 instrument
499 - write support: files created by libgig will now have the RIFF
500 chunks in correct order
501 - write support: two previously unknown fields in dimension
502 definition are now saved
503 - added constants for gig file versions
504 - write support: the 3crc and einf chunks are now created or
505 updated when a file is saved (3crc contains sample checksums,
506 einf contains file statistics)
507 - write support: DLSID is now generated on the file and the
508 instruments
509 - write support: improved the default values for dimension region
510 parameters
511 - more write support fixes: crossfade parameters were not saved,
512 v3 dimension limits were not correctly initialized and saved
513 when dimensions were added or deleted, v3 wave pool offsets were
514 not saved correctly
515 - write support: 24 bit samples can now be written
516 - write support: version 3 is now the default for new files
517 - more write support fixes: the 3ewg chunk is now bigger for v3,
518 dimension regions without mapped samples are now allowed, 3gnl
519 list in v3 files now always has 128 entries, several parameters
520 where incorrectly saved due to an operator precedence mistake
521 - DeleteSample now removes all references to the deleted sample
522 - AddDimension now copies all parameters from existing dimension
523 regions and also makes sure that the samplechannel dimension is
524 placed first in the list of dimensions.
525 - added method GetParent() to class 'DimensionRegion', which returns its
526 parent Region
527 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
528 unused areas
529 - added various setter methods to DimensionRegion class which take care
530 of updating lookup tables / caches.

552 group but moves all its members to another group, the other method,
553 that is File::DeleteGroup() now removes not just the group, but also
554 all the samples that belong to that group
555 - fixed crash which occured on interfering File::DeleteSample() and
556 File::GetNextSample() calls (due to iterator invalidation)
557 - fixed group names which were not saved
558 - fixed group destructor which did not remove the RIFF chunk associated
559 with the group
560 - added Instrument::MoveRegion method
561 - fixed constructor for Region, which did not initialize correctly
562 when used from Instrument::AddRegion
563 - when saving, override the gig::Regions sample reference simply by
564 the region's first dimension region's sample (avoids an exception
565 when trying to save a new instrument)

567 dimension definition fields
568
569 * src/DLS.cpp, src/DLS.h:

702 articulation informations are ignored at the moment
703 (patch by Andreas Persson)
704 - added some file format compatibility checks
705 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

760 SuSE and Fedora)
761 - fixed generation of Doxygen API documentation (now also included in
762 RPM and Debian packages)
763
764 * src/gig.cpp, src/gig.h:
765 - fixed / improved accuracy of all three velocity to volume
766 transformation functions a.k.a. 'nonlinear','linear','special'
767 (patch by Andreas Persson)
768 - denormals are filtered from the velocity to volume tables
769 - bugfix for dimension region switching (wrong handling of the release
770 trigger dimension, no bit range check for dimensions of split type

772 - fixed panorama value in DimensionRegion (invalid conversion from
773 signed 7 bit to signed 8 bit)
774 - added class attribute 'Layers' to class 'gig::Region'
775 - symbol prototyping of gig::Region (fixes build failure with qsampler)
776

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