* Serialization.cpp/.h: Added new method Archive::operation() which
  allows applications to distinguish between serialization vs.
  deserialization in their serialize() method implementations.

* Bumped version (4.2.0.svn12).

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

247 data
248 - added and implemented new parameter "--verify" which allows to check
249 the raw wave form data integrity of all samples
250 - added and implemented new parameter "--rebuild-checksums" which allows
251 to recalculate the CRC32 checksum of all samples' raw wave data and
252 rebuilding the gig file's global checksum table (i.e. in case the
253 file's checksum table was damaged)
254 - print samples' CRC32 checksums
255 - Print the new EG behavior options (eg_opt_t).
256
257 * src/tools/gigextract.cpp:
258 - Fix: if sample name contains a path separator (slash or backslash) then
259 replace them by a minus sign to avoid file system issues.
260
261 * src/tools/gig2stereo.cpp:
262 - Also merge mono sample pairs with non matching loop information if
263 argument --incompatible was given.
264

302
303 * AKAI file format:
304 - Added Linux/POSIX ported version of libakai. Note that libakai is released
305 under LGPL terms while libgig is released under GPL terms. To handle this
306 license difference appropriately the AKAI support part is built as

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

465 - added missing parameter initalizations in sample, region and
466 instrument constructors
467 - clear unused fields when saving samples and regions
468 - fixed write support bugs: v3 dimension limits and chunksize

481 einf contains file statistics)
482 - write support: DLSID is now generated on the file and the
483 instruments
484 - write support: improved the default values for dimension region
485 parameters
486 - more write support fixes: crossfade parameters were not saved,
487 v3 dimension limits were not correctly initialized and saved
488 when dimensions were added or deleted, v3 wave pool offsets were
489 not saved correctly
490 - write support: 24 bit samples can now be written
491 - write support: version 3 is now the default for new files
492 - more write support fixes: the 3ewg chunk is now bigger for v3,
493 dimension regions without mapped samples are now allowed, 3gnl
494 list in v3 files now always has 128 entries, several parameters
495 where incorrectly saved due to an operator precedence mistake
496 - DeleteSample now removes all references to the deleted sample
497 - AddDimension now copies all parameters from existing dimension
498 regions and also makes sure that the samplechannel dimension is
499 placed first in the list of dimensions.
500 - added method GetParent() to class 'DimensionRegion', which returns its
501 parent Region
502 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
503 unused areas
504 - added various setter methods to DimensionRegion class which take care
505 of updating lookup tables / caches.

528 that is File::DeleteGroup() now removes not just the group, but also
529 all the samples that belong to that group
530 - fixed crash which occured on interfering File::DeleteSample() and

535 - added Instrument::MoveRegion method
536 - fixed constructor for Region, which did not initialize correctly
537 when used from Instrument::AddRegion
538 - when saving, override the gig::Regions sample reference simply by
539 the region's first dimension region's sample (avoids an exception
540 when trying to save a new instrument)

542 dimension definition fields
543
544 * src/DLS.cpp, src/DLS.h:

677 articulation informations are ignored at the moment
678 (patch by Andreas Persson)
679 - added some file format compatibility checks
680 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

735 SuSE and Fedora)
736 - fixed generation of Doxygen API documentation (now also included in
737 RPM and Debian packages)
738
739 * src/gig.cpp, src/gig.h:
740 - fixed / improved accuracy of all three velocity to volume
741 transformation functions a.k.a. 'nonlinear','linear','special'
742 (patch by Andreas Persson)
743 - denormals are filtered from the velocity to volume tables
744 - bugfix for dimension region switching (wrong handling of the release
745 trigger dimension, no bit range check for dimensions of split type
746 'split_type_bit')
747 - fixed panorama value in DimensionRegion (invalid conversion from
748 signed 7 bit to signed 8 bit)
749 - added class attribute 'Layers' to class 'gig::Region'
750 - symbol prototyping of gig::Region (fixes build failure with qsampler)
751

771 - added support for generating Debian packages
772 - version of shared library can be set in configure.in
773
774 Version 0.7.0 (3 May 2004)
775
776 * general changes:
777 - various big endian specific corrections
778 (successfully tested now on PPC)
779 - minor adjustments to avoid compile errors on some systems
780 (using now pow() instead of powl() and --pedantic g++ compiler switch)
781 - libtoolized the library
782 - added man pages for the command line tools
783 (gigextract, gigdump, dlsdump, rifftree)
784
785 * src/gig.cpp, src/gig.h:
786 - fixed bug in decompression algorithm which caused it not to detect
787 the end of a stream
788 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
789 takes the MIDI key velocity value as an argument and returns the
790 appropriate volume factor (0.0 ... 1.0) for the sample to be played
791 back, the velocity curve transformation functions used for this are
792 only an approximation so far
793 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
794 'Sample::LoopSize' which reflected wrong values
795 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
796 measured in sample points instead of byte offset
797 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
798 'Sample::FineTune'
799 - added class attribute 'Sample::LoopSize'
800 - added method GetInstrument(uint index) to class 'File'
801 - added ReadAndLoop() method to class 'Sample' which is an extension to
802 the normal Read() method to honor the sample's looping information
803 while streaming from disk
804 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
805 'eg2_ctrl_t': replaced this huge enumeration by a structure which
806 reflects the MIDI controller number in case of an ordinary control
807 change controller (this saves a huge switch-case block in the
808 application of the library user)
809 - renamed following attributes in class 'DimensionRegion':
810 'AttenuationContol' -> 'AttenuationController',
811 'InvertAttenuationControl' -> 'InvertAttenuationController',
812 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
813 - minor fix in API documentation for method GetVelocityAttenuation() in
814 class 'DimensionRegion'
815
816 * src/RIFF.cpp, src/RIFF.h:
817 - added additional API documentation
818 - minor fix in Chunk::Read() method (only a minor efficiency issue)
819
820 * src/gigdump.cpp:
821 - added printout of samples' looping informations
822
823 Version 0.6.0 (3 Nov 2003)
824
825 * initial release
