File size: 39048 byte(s)
* Serialization.h: Fixed assertion fault on some systems if a member
  variable was serialised which was declared as size_t or ssize_t
  data type.

* Bumped version (4.2.0.svn11).

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

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

299
300 * AKAI file format:
301 - Added Linux/POSIX ported version of libakai. Note that libakai is released
302 under LGPL terms while libgig is released under GPL terms. To handle this
303 license difference appropriately the AKAI support part is built as
304 separate DLL (.so file).

408 * src/RIFF.cpp, src/RIFF.h:
409 - bugfix: saving to the same file after the file size had been
410 increased made the file corrupt (#82)
411 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
412 is not written physically yet (#82)

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

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

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

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

530 - fixed group destructor which did not remove the RIFF chunk associated
531 with the group
532 - added Instrument::MoveRegion method
533 - fixed constructor for Region, which did not initialize correctly
534 when used from Instrument::AddRegion
535 - when saving, override the gig::Regions sample reference simply by
536 the region's first dimension region's sample (avoids an exception
537 when trying to save a new instrument)
538 - fixed AddDimension() method which did not fill out all mandatory
539 dimension definition fields
540
541 * src/DLS.cpp, src/DLS.h:
542 - added Instrument::MoveRegion method

613 - added write support
614 - Chunk::LoadChunkData() can now be called again to resize the buffer
615 after a Chunk::Resize() and before the File::Save() call to allow

674 articulation informations are ignored at the moment
675 (patch by Andreas Persson)
676 - added some file format compatibility checks
677 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
678 never used, because the necessary check was made before

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

768 - added support for generating Debian packages
769 - version of shared library can be set in configure.in
770
771 Version 0.7.0 (3 May 2004)
772
773 * general changes:
774 - various big endian specific corrections
775 (successfully tested now on PPC)
776 - minor adjustments to avoid compile errors on some systems
777 (using now pow() instead of powl() and --pedantic g++ compiler switch)
778 - libtoolized the library
779 - added man pages for the command line tools
780 (gigextract, gigdump, dlsdump, rifftree)
781
782 * src/gig.cpp, src/gig.h:
783 - fixed bug in decompression algorithm which caused it not to detect
784 the end of a stream
785 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
786 takes the MIDI key velocity value as an argument and returns the
787 appropriate volume factor (0.0 ... 1.0) for the sample to be played
788 back, the velocity curve transformation functions used for this are
789 only an approximation so far
790 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
791 'Sample::LoopSize' which reflected wrong values
792 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
793 measured in sample points instead of byte offset
794 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
795 'Sample::FineTune'
796 - added class attribute 'Sample::LoopSize'
797 - added method GetInstrument(uint index) to class 'File'
798 - added ReadAndLoop() method to class 'Sample' which is an extension to
799 the normal Read() method to honor the sample's looping information
800 while streaming from disk
801 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
802 'eg2_ctrl_t': replaced this huge enumeration by a structure which
803 reflects the MIDI controller number in case of an ordinary control
804 change controller (this saves a huge switch-case block in the
805 application of the library user)
806 - renamed following attributes in class 'DimensionRegion':
807 'AttenuationContol' -> 'AttenuationController',
808 'InvertAttenuationControl' -> 'InvertAttenuationController',
809 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
810 - minor fix in API documentation for method GetVelocityAttenuation() in
811 class 'DimensionRegion'
812
813 * src/RIFF.cpp, src/RIFF.h:
814 - added additional API documentation
815 - minor fix in Chunk::Read() method (only a minor efficiency issue)
816
817 * src/gigdump.cpp:
818 - added printout of samples' looping informations
819
820 Version 0.6.0 (3 Nov 2003)
821
822 * initial release
