* Require some UUID generating function by underlying system.

* gig.h/.cpp: Script class: Generate a persistent UUID for each script.

* Bumped version (4.2.0.svn7).

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

231 - added and implemented new parameter "--verify" which allows to check
232 the raw wave form data integrity of all samples
233 - added and implemented new parameter "--rebuild-checksums" which allows
234 to recalculate the CRC32 checksum of all samples' raw wave data and
235 rebuilding the gig file's global checksum table (i.e. in case the
236 file's checksum table was damaged)
237 - print samples' CRC32 checksums
238 - Print the new EG behavior options (eg_opt_t).
239
240 * src/tools/gigextract.cpp:
241 - Fix: if sample name contains a path separator (slash or backslash) then
242 replace them by a minus sign to avoid file system issues.
243
244 * src/tools/gig2stereo.cpp:
245 - Also merge mono sample pairs with non matching loop information if
246 argument --incompatible was given.
247

284 (.KMP and .KSF files)
285
286 * AKAI file format:
287 - Added Linux/POSIX ported version of libakai. Note that libakai is released
288 under LGPL terms while libgig is released under GPL terms. To handle this
289 license difference appropriately the AKAI support part is built as
290 separate DLL (.so file).
291 - Fixed Mac OSX support so that the Akai lib files and tools compile without
292 any exotic third party libraries.
293 - Fixed various compilation errors for Windows.

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

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

443 - fixed segmentation fault in the gig::File destructor sequence which
444 happened when gig::Group informations were accessed before
445 - fixed write support for big-endian systems
446 - defined lengths of a fixed set of info strings. These strings

448 - added missing parameter initalizations in sample, region and
449 instrument constructors
450 - clear unused fields when saving samples and regions
451 - fixed write support bugs: v3 dimension limits and chunksize
452 weren't saved, leverage controller of type controlchange
453 couldn't be saved, group name list chunk was placed wrong,
454 dimension region chunks also placed wrong
455 - added initialization of some fixed info strings in file and
456 instrument
457 - write support: files created by libgig will now have the RIFF

459 - write support: two previously unknown fields in dimension
460 definition are now saved
461 - added constants for gig file versions
462 - write support: the 3crc and einf chunks are now created or
463 updated when a file is saved (3crc contains sample checksums,
464 einf contains file statistics)
465 - write support: DLSID is now generated on the file and the
466 instruments
467 - write support: improved the default values for dimension region
468 parameters
469 - more write support fixes: crossfade parameters were not saved,
470 v3 dimension limits were not correctly initialized and saved
471 when dimensions were added or deleted, v3 wave pool offsets were
472 not saved correctly
473 - write support: 24 bit samples can now be written
474 - write support: version 3 is now the default for new files
475 - more write support fixes: the 3ewg chunk is now bigger for v3,
476 dimension regions without mapped samples are now allowed, 3gnl
477 list in v3 files now always has 128 entries, several parameters
478 where incorrectly saved due to an operator precedence mistake
479 - DeleteSample now removes all references to the deleted sample
480 - AddDimension now copies all parameters from existing dimension
481 regions and also makes sure that the samplechannel dimension is
482 placed first in the list of dimensions.
483 - added method GetParent() to class 'DimensionRegion', which returns its
484 parent Region
485 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
486 unused areas
487 - added various setter methods to DimensionRegion class which take care
488 of updating lookup tables / caches.
489

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

519 - fixed constructor for Region, which did not initialize correctly
520 when used from Instrument::AddRegion
521 - when saving, override the gig::Regions sample reference simply by
522 the region's first dimension region's sample (avoids an exception
523 when trying to save a new instrument)
524 - fixed AddDimension() method which did not fill out all mandatory
525 dimension definition fields
526
527 * src/DLS.cpp, src/DLS.h:
528 - added Instrument::MoveRegion method

660 articulation informations are ignored at the moment
661 (patch by Andreas Persson)
662 - added some file format compatibility checks
663 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
664 never used, because the necessary check was made before

713
714 * packaging changes:
715 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
716 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
717 - fixed man pages automake install rule (which didn't work on Mandrake,
718 SuSE and Fedora)
719 - fixed generation of Doxygen API documentation (now also included in
720 RPM and Debian packages)
721
722 * src/gig.cpp, src/gig.h:
723 - fixed / improved accuracy of all three velocity to volume
724 transformation functions a.k.a. 'nonlinear','linear','special'
725 (patch by Andreas Persson)
726 - denormals are filtered from the velocity to volume tables
727 - bugfix for dimension region switching (wrong handling of the release
728 trigger dimension, no bit range check for dimensions of split type
729 'split_type_bit')

731 signed 7 bit to signed 8 bit)
732 - added class attribute 'Layers' to class 'gig::Region'
733 - symbol prototyping of gig::Region (fixes build failure with qsampler)
734

750 - added libgig.spec and libgig.pc package configurations for generating
751 Redhat packages
752 - header files included on installation.
753 - autotools-generated files removed from CVS repository.
754 - added support for generating Debian packages
755 - version of shared library can be set in configure.in
756
757 Version 0.7.0 (3 May 2004)
758
759 * general changes:
760 - various big endian specific corrections
761 (successfully tested now on PPC)
762 - minor adjustments to avoid compile errors on some systems
763 (using now pow() instead of powl() and --pedantic g++ compiler switch)
764 - libtoolized the library
765 - added man pages for the command line tools
766 (gigextract, gigdump, dlsdump, rifftree)
767
768 * src/gig.cpp, src/gig.h:
769 - fixed bug in decompression algorithm which caused it not to detect
770 the end of a stream
771 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
772 takes the MIDI key velocity value as an argument and returns the
773 appropriate volume factor (0.0 ... 1.0) for the sample to be played
774 back, the velocity curve transformation functions used for this are
775 only an approximation so far
776 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
777 'Sample::LoopSize' which reflected wrong values
778 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
779 measured in sample points instead of byte offset
780 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
781 'Sample::FineTune'
782 - added class attribute 'Sample::LoopSize'
783 - added method GetInstrument(uint index) to class 'File'
784 - added ReadAndLoop() method to class 'Sample' which is an extension to
785 the normal Read() method to honor the sample's looping information
786 while streaming from disk
787 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
788 'eg2_ctrl_t': replaced this huge enumeration by a structure which
789 reflects the MIDI controller number in case of an ordinary control
790 change controller (this saves a huge switch-case block in the
791 application of the library user)
792 - renamed following attributes in class 'DimensionRegion':
793 'AttenuationContol' -> 'AttenuationController',
794 'InvertAttenuationControl' -> 'InvertAttenuationController',
795 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
796 - minor fix in API documentation for method GetVelocityAttenuation() in
797 class 'DimensionRegion'
798
799 * src/RIFF.cpp, src/RIFF.h:
800 - added additional API documentation
801 - minor fix in Chunk::Read() method (only a minor efficiency issue)
802
803 * src/gigdump.cpp:
804 - added printout of samples' looping informations
805
806 Version 0.6.0 (3 Nov 2003)
807
808 * initial release
