File size: 39978 byte(s)
* src/gig.cpp: Fixed undefined behaviour when modifying script slots on an
  instrument that had been cloned and not been saved yet (e.g. unintended
  modification of original instrument's script slots, and crash on
  Instrument destruction due to double free of pScriptRefs).

* Bumped version (4.2.0.svn17).

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

260 data
261 - added and implemented new parameter "--verify" which allows to check
262 the raw wave form data integrity of all samples
263 - added and implemented new parameter "--rebuild-checksums" which allows
264 to recalculate the CRC32 checksum of all samples' raw wave data and
265 rebuilding the gig file's global checksum table (i.e. in case the
266 file's checksum table was damaged)
267 - print samples' CRC32 checksums
268 - Print the new EG behavior options (eg_opt_t).
269
270 * src/tools/gigextract.cpp:
271 - Fix: if sample name contains a path separator (slash or backslash) then
272 replace them by a minus sign to avoid file system issues.
273
274 * src/tools/gig2stereo.cpp:
275 - Also merge mono sample pairs with non matching loop information if
276 argument --incompatible was given.
277

314 (.KMP and .KSF files)
315
316 * AKAI file format:
317 - Added Linux/POSIX ported version of libakai. Note that libakai is released
318 under LGPL terms while libgig is released under GPL terms. To handle this
319 license difference appropriately the AKAI support part is built as

360 of instruments within the same gig file.
361

422 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
423
424 * src/RIFF.cpp, src/RIFF.h:
425 - bugfix: saving to the same file after the file size had been
426 increased made the file corrupt (#82)
427 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
428 is not written physically yet (#82)

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

474 happened when gig::Group informations were accessed before
475 - fixed write support for big-endian systems
476 - defined lengths of a fixed set of info strings. These strings
477 are saved when the file is written, even if they are empty.
478 - added missing parameter initalizations in sample, region and
479 instrument constructors
480 - clear unused fields when saving samples and regions
481 - fixed write support bugs: v3 dimension limits and chunksize
482 weren't saved, leverage controller of type controlchange
483 couldn't be saved, group name list chunk was placed wrong,
484 dimension region chunks also placed wrong
485 - added initialization of some fixed info strings in file and
486 instrument
487 - write support: files created by libgig will now have the RIFF
488 chunks in correct order
489 - write support: two previously unknown fields in dimension
490 definition are now saved
491 - added constants for gig file versions
492 - write support: the 3crc and einf chunks are now created or
493 updated when a file is saved (3crc contains sample checksums,
494 einf contains file statistics)
495 - write support: DLSID is now generated on the file and the
496 instruments
497 - write support: improved the default values for dimension region
498 parameters
499 - more write support fixes: crossfade parameters were not saved,
500 v3 dimension limits were not correctly initialized and saved
501 when dimensions were added or deleted, v3 wave pool offsets were
502 not saved correctly
503 - write support: 24 bit samples can now be written
504 - write support: version 3 is now the default for new files
505 - more write support fixes: the 3ewg chunk is now bigger for v3,
506 dimension regions without mapped samples are now allowed, 3gnl
507 list in v3 files now always has 128 entries, several parameters
508 where incorrectly saved due to an operator precedence mistake
509 - DeleteSample now removes all references to the deleted sample
510 - AddDimension now copies all parameters from existing dimension
511 regions and also makes sure that the samplechannel dimension is
512 placed first in the list of dimensions.
513 - added method GetParent() to class 'DimensionRegion', which returns its
514 parent Region
515 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
516 unused areas
517 - added various setter methods to DimensionRegion class which take care
518 of updating lookup tables / caches.
519

535 - custom velocity splits now works for gig v3 files too
536 - added support for custom splits points for other dimensions than
537 velocity (gig v3 feature)
538 - added "smart midi" and "round robin keyboard" dimensions
539 - added new method File::DeleteGroupOnly() which only deletes the given
540 group but moves all its members to another group, the other method,
541 that is File::DeleteGroup() now removes not just the group, but also
542 all the samples that belong to that group
543 - fixed crash which occured on interfering File::DeleteSample() and
544 File::GetNextSample() calls (due to iterator invalidation)
545 - fixed group names which were not saved
546 - fixed group destructor which did not remove the RIFF chunk associated
547 with the group
548 - added Instrument::MoveRegion method
549 - fixed constructor for Region, which did not initialize correctly
550 when used from Instrument::AddRegion
551 - when saving, override the gig::Regions sample reference simply by
552 the region's first dimension region's sample (avoids an exception
553 when trying to save a new instrument)
554 - fixed AddDimension() method which did not fill out all mandatory
555 dimension definition fields
556
557 * src/DLS.cpp, src/DLS.h:

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

690 articulation informations are ignored at the moment
691 (patch by Andreas Persson)
692 - added some file format compatibility checks
693 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

743
744 * packaging changes:
745 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
746 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
747 - fixed man pages automake install rule (which didn't work on Mandrake,
748 SuSE and Fedora)
749 - fixed generation of Doxygen API documentation (now also included in
750 RPM and Debian packages)
751
752 * src/gig.cpp, src/gig.h:
753 - fixed / improved accuracy of all three velocity to volume
754 transformation functions a.k.a. 'nonlinear','linear','special'
755 (patch by Andreas Persson)
756 - denormals are filtered from the velocity to volume tables
757 - bugfix for dimension region switching (wrong handling of the release
758 trigger dimension, no bit range check for dimensions of split type
759 'split_type_bit')
760 - fixed panorama value in DimensionRegion (invalid conversion from
761 signed 7 bit to signed 8 bit)
762 - added class attribute 'Layers' to class 'gig::Region'
763 - symbol prototyping of gig::Region (fixes build failure with qsampler)
764

784 - added support for generating Debian packages
785 - version of shared library can be set in configure.in
786
787 Version 0.7.0 (3 May 2004)
788
789 * general changes:
790 - various big endian specific corrections
791 (successfully tested now on PPC)
792 - minor adjustments to avoid compile errors on some systems
793 (using now pow() instead of powl() and --pedantic g++ compiler switch)
794 - libtoolized the library
795 - added man pages for the command line tools
796 (gigextract, gigdump, dlsdump, rifftree)
797
798 * src/gig.cpp, src/gig.h:
799 - fixed bug in decompression algorithm which caused it not to detect
800 the end of a stream
801 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
802 takes the MIDI key velocity value as an argument and returns the
803 appropriate volume factor (0.0 ... 1.0) for the sample to be played
804 back, the velocity curve transformation functions used for this are
805 only an approximation so far
806 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
807 'Sample::LoopSize' which reflected wrong values
808 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
809 measured in sample points instead of byte offset
810 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
811 'Sample::FineTune'
812 - added class attribute 'Sample::LoopSize'
813 - added method GetInstrument(uint index) to class 'File'
814 - added ReadAndLoop() method to class 'Sample' which is an extension to
815 the normal Read() method to honor the sample's looping information
816 while streaming from disk
817 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
818 'eg2_ctrl_t': replaced this huge enumeration by a structure which
819 reflects the MIDI controller number in case of an ordinary control
820 change controller (this saves a huge switch-case block in the
821 application of the library user)
822 - renamed following attributes in class 'DimensionRegion':
823 'AttenuationContol' -> 'AttenuationController',
824 'InvertAttenuationControl' -> 'InvertAttenuationController',
825 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
826 - minor fix in API documentation for method GetVelocityAttenuation() in
827 class 'DimensionRegion'
828
829 * src/RIFF.cpp, src/RIFF.h:
830 - added additional API documentation
831 - minor fix in Chunk::Read() method (only a minor efficiency issue)
832
833 * src/gigdump.cpp:
834 - added printout of samples' looping informations
835
836 Version 0.6.0 (3 Nov 2003)
837
838 * initial release
