* GIG FORMAT EXTENSION: added LinuxSampler specific filter type
  implementations to enum gig::vcf_type_t: vcf_type_lowpass_1p,
  vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
  vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
  vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.

* Bumped version (4.2.0.svn2).

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

220 - added and implemented new parameter "--verify" which allows to check
221 the raw wave form data integrity of all samples
222 - added and implemented new parameter "--rebuild-checksums" which allows
223 to recalculate the CRC32 checksum of all samples' raw wave data and
224 rebuilding the gig file's global checksum table (i.e. in case the
225 file's checksum table was damaged)
226 - print samples' CRC32 checksums
227 - Print the new EG behavior options (eg_opt_t).
228
229 * src/tools/gigextract.cpp:
230 - Fix: if sample name contains a path separator (slash or backslash) then
231 replace them by a minus sign to avoid file system issues.
232
233 * src/tools/gig2stereo.cpp:
234 - Also merge mono sample pairs with non matching loop information if
235 argument --incompatible was given.

274
275 * AKAI file format:
276 - Added Linux/POSIX ported version of libakai. Note that libakai is released
277 under LGPL terms while libgig is released under GPL terms. To handle this
278 license difference appropriately the AKAI support part is built as
279 separate DLL (.so file).
280 - Fixed Mac OSX support so that the Akai lib files and tools compile without
281 any exotic third party libraries.

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

437 - added missing parameter initalizations in sample, region and
438 instrument constructors
439 - clear unused fields when saving samples and regions
440 - fixed write support bugs: v3 dimension limits and chunksize
441 weren't saved, leverage controller of type controlchange
442 couldn't be saved, group name list chunk was placed wrong,
443 dimension region chunks also placed wrong

449 definition are now saved
450 - added constants for gig file versions
451 - write support: the 3crc and einf chunks are now created or
452 updated when a file is saved (3crc contains sample checksums,
453 einf contains file statistics)
454 - write support: DLSID is now generated on the file and the
455 instruments
456 - write support: improved the default values for dimension region
457 parameters
458 - more write support fixes: crossfade parameters were not saved,
459 v3 dimension limits were not correctly initialized and saved
460 when dimensions were added or deleted, v3 wave pool offsets were
461 not saved correctly
462 - write support: 24 bit samples can now be written
463 - write support: version 3 is now the default for new files
464 - more write support fixes: the 3ewg chunk is now bigger for v3,

466 list in v3 files now always has 128 entries, several parameters
467 where incorrectly saved due to an operator precedence mistake
468 - DeleteSample now removes all references to the deleted sample
469 - AddDimension now copies all parameters from existing dimension
470 regions and also makes sure that the samplechannel dimension is
471 placed first in the list of dimensions.
472 - added method GetParent() to class 'DimensionRegion', which returns its
473 parent Region
474 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
475 unused areas
476 - added various setter methods to DimensionRegion class which take care
477 of updating lookup tables / caches.
478
479 * src/RIFF.cpp, src/RIFF.h:
480 - added File::SetByteOrder method
481 - Windows fix: saving a new file didn't work

499 group but moves all its members to another group, the other method,
500 that is File::DeleteGroup() now removes not just the group, but also
501 all the samples that belong to that group
502 - fixed crash which occured on interfering File::DeleteSample() and

506 with the group
507 - added Instrument::MoveRegion method
508 - fixed constructor for Region, which did not initialize correctly
509 when used from Instrument::AddRegion
510 - when saving, override the gig::Regions sample reference simply by
511 the region's first dimension region's sample (avoids an exception
512 when trying to save a new instrument)
513 - fixed AddDimension() method which did not fill out all mandatory
514 dimension definition fields
515
516 * src/DLS.cpp, src/DLS.h:
517 - added Instrument::MoveRegion method

519 causing an exception when trying to save a new instrument
520
521 * src/RIFF.cpp, src/RIFF.h:

576 - fixed the GetVelocityCutoff function, it wasn't always using the
577 VCFVelocityScale parameter when no cutoff controller was defined
578 - support for the gig v3 feature to have a number of dimension
579 splits not equal to a power of two
580 - added write support (highly experimental)

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

649 articulation informations are ignored at the moment
650 (patch by Andreas Persson)
651 - added some file format compatibility checks
652 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
653 never used, because the necessary check was made before

702
703 * packaging changes:
704 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
705 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
706 - fixed man pages automake install rule (which didn't work on Mandrake,
707 SuSE and Fedora)
708 - fixed generation of Doxygen API documentation (now also included in
709 RPM and Debian packages)
710
711 * src/gig.cpp, src/gig.h:
712 - fixed / improved accuracy of all three velocity to volume
713 transformation functions a.k.a. 'nonlinear','linear','special'
714 (patch by Andreas Persson)
715 - denormals are filtered from the velocity to volume tables
716 - bugfix for dimension region switching (wrong handling of the release
717 trigger dimension, no bit range check for dimensions of split type
718 'split_type_bit')
719 - fixed panorama value in DimensionRegion (invalid conversion from
720 signed 7 bit to signed 8 bit)
721 - added class attribute 'Layers' to class 'gig::Region'
722 - symbol prototyping of gig::Region (fixes build failure with qsampler)
723

736 Version 0.7.1 (2 Jul 2004)
737
738 * packaging changes:
739 - added libgig.spec and libgig.pc package configurations for generating
740 Redhat packages
741 - header files included on installation.
742 - autotools-generated files removed from CVS repository.
743 - added support for generating Debian packages
744 - version of shared library can be set in configure.in
745
746 Version 0.7.0 (3 May 2004)
747
748 * general changes:
749 - various big endian specific corrections
750 (successfully tested now on PPC)
751 - minor adjustments to avoid compile errors on some systems
752 (using now pow() instead of powl() and --pedantic g++ compiler switch)
753 - libtoolized the library
754 - added man pages for the command line tools
755 (gigextract, gigdump, dlsdump, rifftree)
756
757 * src/gig.cpp, src/gig.h:
758 - fixed bug in decompression algorithm which caused it not to detect
759 the end of a stream
760 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
761 takes the MIDI key velocity value as an argument and returns the
762 appropriate volume factor (0.0 ... 1.0) for the sample to be played
763 back, the velocity curve transformation functions used for this are
764 only an approximation so far
765 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
766 'Sample::LoopSize' which reflected wrong values
767 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
768 measured in sample points instead of byte offset
769 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
770 'Sample::FineTune'
771 - added class attribute 'Sample::LoopSize'
772 - added method GetInstrument(uint index) to class 'File'
773 - added ReadAndLoop() method to class 'Sample' which is an extension to
774 the normal Read() method to honor the sample's looping information
775 while streaming from disk
776 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
777 'eg2_ctrl_t': replaced this huge enumeration by a structure which
778 reflects the MIDI controller number in case of an ordinary control
779 change controller (this saves a huge switch-case block in the
780 application of the library user)
781 - renamed following attributes in class 'DimensionRegion':
782 'AttenuationContol' -> 'AttenuationController',
783 'InvertAttenuationControl' -> 'InvertAttenuationController',
784 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
785 - minor fix in API documentation for method GetVelocityAttenuation() in
786 class 'DimensionRegion'
787
788 * src/RIFF.cpp, src/RIFF.h:
789 - added additional API documentation
790 - minor fix in Chunk::Read() method (only a minor efficiency issue)
791
792 * src/gigdump.cpp:
793 - added printout of samples' looping informations
794
795 Version 0.6.0 (3 Nov 2003)
796
797 * initial release
