13
14 Version 4.3.0 (9 May 2021)
15
16 * general changes:
17 - Require at least a C++11 compliant compiler.
18 - Require some UUID generating function by underlying system.
19
20 * src/gig.cpp, src/gig.h:
21 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
22 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
23 allow to define override LFOs' wave form (e.g. saw or square instead of
24 the default wave form which was always sine in the original
25 Gigasampler/GigaStudio software).
26 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
27 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
28 move the start point horizontally of the LFOs' waves (0�� ... 360��).
29 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
30 (the original Gigasampler/GigaStudio software only had that flip phase
31 option for LFO1 and LFO2).
32 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
33 Region::UsesAnyGigFormatExtension(),
34 Instrument::UsesAnyGigFormatExtension() and
35 File::UsesAnyGigFormatExtension() (however only as private methods yet,
36 see comments on methods why).
37 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
38 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
39 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
40 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
41 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
42 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
43 (patch by Ivan Maguidhir).
44 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
45 (original patch by Ivan Maguidhir).
46 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
47 dimensions being in different order after deleting a dimension zone.
48 - Script: Generate a persistent UUID for each script.
49 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
50 accordingly added new methods to Instrument class:
51 IsScriptPatchVariableSet(), GetScriptPatchVariables(),
52 GetScriptPatchVariable(), SetScriptPatchVariable(),
53 UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
54 as child of our '3LS ' list chunk on Instrument level.
55 - Fixed undefined behaviour when modifying script slots on an instrument
56 that had been cloned and not been saved yet (e.g. unintended modification
57 of original instrument's script slots, and crash on Instrument destruction
58 due to double free of pScriptRefs).
59
60 * src/Serialization.cpp, src/Serialization.h:
61 - Fixed broken Archive(RawData) constructor which always threw an
62 Exception.
63 - Added built-in support for C++ String objects (a.k.a. std::string
64 from the STL) and bumped Srx format version to 1.1 for that reason.
65 - Fixed assertion fault on some systems if a member variable defined was
66 serialized which was declared as size_t or ssize_t data type.
67 - Added new method Archive::operation() which allows applications to
68 distinguish between serialization vs. deserialization in their
69 serialize() method implementations.
70 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
71 the STL).
72 - Member offsets are now signed and for (newly added support of) member
73 variables on the heap -1 is always used as offset instead.
74 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
75 STL).
76 - DataType: Added optional 2nd custom type name.
77 - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
78 STL).
79
80 * src/helper.h:
81 - Fix compile error with GCC 9 due to ignored result value of vasprintf()
82 function call.
83
84 * src/tools/gigdump.cpp:
85 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
86 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
87 LFO2FlipPhase and LFO3FlipPhase.
88
89 Version 4.2.0 (25 Jul 2019)
90
91 * general changes:
92 - Added MSVC build support (anonymous patch from mailing list).
93 - Introduced CMake build support (yet constrained for building with MSVC)
94 (anonymous patch from mailing list).
95 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
96 destructors. Added new virtual method DeleteChunks() to those classes
97 for this which must be explicitly called instead to remove their RIFF
98 chunks.
99 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
100 of zero; which is unsafe per se.
101 - Added C++11 "override" keyword where appropriate.
102 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
103 of their actions when not passing a progress_t callback structure.
104
105 * src/gig.cpp, src/gig.h:
106 - Fixed Doxygen API comments for enum types (currently latest Doxygen
107 [v1.8.13] only supports C comments in macro arguments expansion, but
108 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
109 the Doxygen source code, which currently also filter out new line
110 \n chars).
111 - Added new method File::CountSamples().
112 - Added new method File::CountInstruments().
113 - Fixed gig v4 files falsely being handled as v2 format
114 (patch by Ivan Maguidhir).
115 - Added gig v4 version identifier (File::VERSION_4).
116 - GIG FORMAT EXTENSION: Added attribute
117 DimensionRegion::SustainReleaseTrigger which allows to define whether
118 a sustain pedal up event shall cause a release trigger sample to be
119 played (default: don't play release trigger sample by sustain pedal).
120 - GIG FORMAT EXTENSION: Added attribute
121 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
122 regular behaviour of playing release trigger sample on MIDI note-off
123 events.
124 - Introduced support for writing extension files (.gx01, .gx02, ...)
125 (original patch by Ivan Maguidhir).
126 - Many gig classes derive now from DLS::Storage (see DLS changes below).
127 - Added File::GetRiffFile() method.
128
129 * src/DLS.cpp, src/DLS.h:
130 - File: Fixed implicitly allocated RIFF::File object never been freed.
131 - Added new abstract interface base class DLS::Storage which is derived by
132 the respective classes for implementing (the old) UpdateChunks() and the
133 new DeleteChunks() method.
134 - Added File::GetRiffFile() method.
135
136 * src/sf2.cpp, src/sf2.h:
137 - Added Sample::GetFile() method.
138 - Added File::GetRiffFile() method.
139
140 * src/Serialization.cpp, src/Serialization.h:
141 - Hide pure internal declarations from header file to avoid numerous
142 compiler warnings when building and linking against the public API.
143 - Fixed comparision logic bug
144 - Fixed memory leak in DataType::customTypeName().
145
146 * src/RIFF.cpp, src/RIFF.h:
147 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
148 caused a resource leak
149 - Avoid compiler warning when building for 32 bit windows.
150 - Added new method progress_t::subdivide().
151 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
152 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
153 allows a more fine graded control into which portions the subtasks are
154 divided to.
155
156 * src/tools/gigdump.cpp:
157 - Added command line option --instrument-names which causes only
158 instrument names and their index numbers to be printed.
159
160 Version 4.1.0 (25 Nov 2017)
161 * general changes:
162 - removed 2 GB limitation when loading a gig or DLS file
163 - using now native integer size where appropriate
164 - fixed minor issues with man pages (patch by Debian maintainer)
165 - fixed various spelling mistakes (patch by Debian maintainer)
166 - Added new "Serialization" framework (and equally named namespace)
167 which allows to serialize and deserialize native C++ objects
168 in a portable, easy and flexible way.
169 - print compiler warning if no RTTI available
170 - Fixed potential crash in command line tools gig2stereo, korg2gig,
171 korgdump and sf2extract.
172 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
173 (original patch by Paul Brossier, slightly modified).
174 - Debian: Fixed packaging error about invalid substitution variable
175 "Source-Version".
176 - Raised Debian compatibility level to Debian 9 "Stretch".
177
178 * src/gig.cpp, src/gig.h:
179 - fixed bug in Script::SetGroup: the script chunk wasn't moved
180 - fixed compilation error with clang 3.4
181 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
182 as one single monolithic gig file. In case .gig file is >= 2GB expect a
183 large monolithic file, otherwise if .gig file is < 2 GB check for
184 "extension" files (.gx01, .gx02, ...) instead.
185 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
186 if there were dimensions after the velocity dimension: it only created
187 valid velocity tables for cases of dimensions lower than the velocity
188 dimension.
189 - added new method Sample::VerifyWaveData() which allows to check whether
190 a sample had been damaged for some reason
191 - Fix: samples' CRC checksums were damaged on file structure changes.
192 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
193 - Added new method Sample::GetWaveDataCRC32Checksum().
194 - Changed default value of EG2Release (filter release time) to 60s.
195 - Instruments' default pitch bend range is now +-2 semi tones.
196 - Fixed CRC checksums being wrong sometimes.
197 - Fix: method File::AddContentOf() did not clone script groups and scripts
198 of passed original file.
199 - Added support for serializing & deserializing DimensionRegion
200 objects (and crossfade_t and leverage_ctrl_t objects).
201 - Added enum reflection API functions for retrieving enum declaration type
202 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
203 - Exception class now has a variadic constructor which allows to add
204 textual format specifiers like with printf().
205 - On unknown leverage controller exception: show precise unknown leverage
206 controller number found.
207 - Ignore invalid leverage controller types and just show a warning on the
208 console instead of throwing an exception.
209 - Added new struct eg_opt_t and new class member variable
210 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
211 extension to the gig file format, which allows to override the default
212 behavior of the first two EGs' state machines.
213 - Fixed undefined behavior when loading a gig file with invalid
214 velocity curve parameters (fixes CVE-2017-12951).
215 - Fixed undefined behavior when loading a gig file with invalid wave
216 pool index number (fixes CVE-2017-12954).
217
218 * src/DLS.cpp, src/DLS.h:
219 - Sample: wave pool offsets are now 64 bits (to allow support for files
220 larger than 4 GB).
221 - Exception class now has a variadic constructor which allows to add
222 textual format specifiers like with printf().
223
224 * src/RIFF.cpp, src/RIFF.h:
225 - added support for RIFF files larger than 4 GB, by default the required
226 internal RIFF file offset size is automatically detected (that is RIFF
227 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
228 automatically use 64 bit offsets), a particular offset size can be forced
229 with a new option added to the RIFF File constructor though
230 - when saving a modified, grown RIFF file, the temporary file size during
231 Save() operation will no longer be larger than the final grown file size
232 - Exception class now has a variadic constructor which allows to add
233 textual format specifiers like with printf().
234
235 * src/Serialization.cpp, src/Serialization.h:
236 - Archive: Added method isModified().
237 - Archive: Added method setAutoValue().
238 - Archive: Added method setIntValue().
239 - Archive: Added method setRealValue().
240 - Archive: Added method setBoolValue().
241 - Archive: Added method setEnumValue().
242 - Archive: Added method valueAsString().
243 - Archive::rawData(): Automatically re-encode new raw data stream if
244 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
245 - Object: Added method memberByUID().
246 - Object: remove() method is now protected.
247 - Archive: Added method removeMember().
248 - Archive: Added methods name() and setName().
249 - Archive: Added methods comment() and setComment().
250 - Archive: Added methods timeStampCreated(), timeStampModified(),
251 dateTimeCreated() and dateTimeModified().
252 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
253 - DataType: Implemented demangling C++ type names (for methods
254 asLongDescr() and customTypeName(bool demangle=false)).
255 - Archive::setAutoValue(): Handle human readable boolean text
256 representations like "yes", "no", "true", "false" as expected.
257 - Exception class now has a variadic constructor which allows to add
258 textual format specifiers like with printf().
259 - DataType fix: Retain backward compatibility to older versions of native
260 C++ classes/structs.
261
262 * src/Akai.cpp:
263 - Fixed compilation error with recent, more strict compilers.
264
265 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
266 - improved output of non-ascii characters in usage messages

277 data
278 - added and implemented new parameter "--verify" which allows to check
279 the raw wave form data integrity of all samples
280 - added and implemented new parameter "--rebuild-checksums" which allows
281 to recalculate the CRC32 checksum of all samples' raw wave data and
282 rebuilding the gig file's global checksum table (i.e. in case the
283 file's checksum table was damaged)
284 - print samples' CRC32 checksums
285 - Print the new EG behavior options (eg_opt_t).
286
287 * src/tools/gigextract.cpp:
288 - Fix: if sample name contains a path separator (slash or backslash) then
289 replace them by a minus sign to avoid file system issues.
290
291 * src/tools/gig2stereo.cpp:
292 - Also merge mono sample pairs with non matching loop information if
293 argument --incompatible was given.
294

332
333 * AKAI file format:
334 - Added Linux/POSIX ported version of libakai. Note that libakai is released

377 of instruments within the same gig file.
378

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

415 - Cleanup of an old DLL binary backward compatibility hack.
416
417 * src/gigextract.cpp:
418 - export sample loop, unity note and fine tune with libsndfile

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

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

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

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

513 instruments
514 - write support: improved the default values for dimension region
515 parameters
516 - more write support fixes: crossfade parameters were not saved,
517 v3 dimension limits were not correctly initialized and saved
518 when dimensions were added or deleted, v3 wave pool offsets were
519 not saved correctly
520 - write support: 24 bit samples can now be written
521 - write support: version 3 is now the default for new files
522 - more write support fixes: the 3ewg chunk is now bigger for v3,
523 dimension regions without mapped samples are now allowed, 3gnl
524 list in v3 files now always has 128 entries, several parameters
525 where incorrectly saved due to an operator precedence mistake
526 - DeleteSample now removes all references to the deleted sample
527 - AddDimension now copies all parameters from existing dimension
528 regions and also makes sure that the samplechannel dimension is
529 placed first in the list of dimensions.
530 - added method GetParent() to class 'DimensionRegion', which returns its
531 parent Region
532 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
533 unused areas
534 - added various setter methods to DimensionRegion class which take care
535 of updating lookup tables / caches.

557 group but moves all its members to another group, the other method,
558 that is File::DeleteGroup() now removes not just the group, but also
559 all the samples that belong to that group
560 - fixed crash which occured on interfering File::DeleteSample() and
561 File::GetNextSample() calls (due to iterator invalidation)

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

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

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

765 SuSE and Fedora)
766 - fixed generation of Doxygen API documentation (now also included in
767 RPM and Debian packages)
768
769 * src/gig.cpp, src/gig.h:
770 - fixed / improved accuracy of all three velocity to volume
771 transformation functions a.k.a. 'nonlinear','linear','special'
772 (patch by Andreas Persson)
773 - denormals are filtered from the velocity to volume tables
774 - bugfix for dimension region switching (wrong handling of the release
775 trigger dimension, no bit range check for dimensions of split type
776 'split_type_bit')
777 - fixed panorama value in DimensionRegion (invalid conversion from
778 signed 7 bit to signed 8 bit)
779 - added class attribute 'Layers' to class 'gig::Region'
780 - symbol prototyping of gig::Region (fixes build failure with qsampler)
781

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