* Compatibility fix (gig.cpp): GigaStudio always expects 128 '3gnm' RIFF
  chunks (patch by Ivan Maguidhir).

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

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

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

319 (chunks at wrong location in the RIFF tree).
320 - Added new method Instrument::MoveTo() which allows to rearrange the order
321 of instruments within the same gig file.
322

386 - bugfix: saving to the same file after the file size had been
387 increased made the file corrupt (#82)
388 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
389 is not written physically yet (#82)

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

439 - added missing parameter initalizations in sample, region and
440 instrument constructors
441 - clear unused fields when saving samples and regions
442 - fixed write support bugs: v3 dimension limits and chunksize

451 definition are now saved
452 - added constants for gig file versions
453 - write support: the 3crc and einf chunks are now created or
454 updated when a file is saved (3crc contains sample checksums,

456 - write support: DLSID is now generated on the file and the
457 instruments
458 - write support: improved the default values for dimension region
459 parameters
460 - more write support fixes: crossfade parameters were not saved,
461 v3 dimension limits were not correctly initialized and saved
462 when dimensions were added or deleted, v3 wave pool offsets were
463 not saved correctly
464 - write support: 24 bit samples can now be written
465 - write support: version 3 is now the default for new files
466 - more write support fixes: the 3ewg chunk is now bigger for v3,

468 list in v3 files now always has 128 entries, several parameters
469 where incorrectly saved due to an operator precedence mistake
470 - DeleteSample now removes all references to the deleted sample
471 - AddDimension now copies all parameters from existing dimension
472 regions and also makes sure that the samplechannel dimension is
473 placed first in the list of dimensions.

475 parent Region
476 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
477 unused areas

487
488 Version 3.1.1 (24 Mar 2007)
489
490 * packaging changes:

496 - custom velocity splits now works for gig v3 files too
497 - added support for custom splits points for other dimensions than
498 velocity (gig v3 feature)
499 - added "smart midi" and "round robin keyboard" dimensions
500 - added new method File::DeleteGroupOnly() which only deletes the given
501 group but moves all its members to another group, the other method,
502 that is File::DeleteGroup() now removes not just the group, but also
503 all the samples that belong to that group
504 - fixed crash which occured on interfering File::DeleteSample() and
505 File::GetNextSample() calls (due to iterator invalidation)
506 - fixed group names which were not saved
507 - fixed group destructor which did not remove the RIFF chunk associated
508 with the group
509 - added Instrument::MoveRegion method
510 - fixed constructor for Region, which did not initialize correctly
511 when used from Instrument::AddRegion
512 - when saving, override the gig::Regions sample reference simply by
513 the region's first dimension region's sample (avoids an exception
514 when trying to save a new instrument)
515 - fixed AddDimension() method which did not fill out all mandatory
516 dimension definition fields
517
518 * src/DLS.cpp, src/DLS.h:
519 - added Instrument::MoveRegion method
520 - fixed software info field which was wrongly stored on instruments,
521 causing an exception when trying to save a new instrument
522
523 * src/RIFF.cpp, src/RIFF.h:
524 - fixed RIFF::Chunk destructor which did not unregister previously
525 resized chunks, leading to a "zero size chunk" exception when
526 File::Save() was called
527 - added List::MoveSubChunk method
528

578 - fixed the GetVelocityCutoff function, it wasn't always using the
579 VCFVelocityScale parameter when no cutoff controller was defined
580 - support for the gig v3 feature to have a number of dimension
581 splits not equal to a power of two
582 - added write support (highly experimental)
583

590 - added write support
591 - Chunk::LoadChunkData() can now be called again to resize the buffer
592 after a Chunk::Resize() and before the File::Save() call to allow
593 placing the new data in the chunk's write buffer and perform the
594 resize and write operations in one rush
595
596 * src/gigdump.cpp:
597 - fixed to show the correct amount of dimension regions instead of 32
598 (patch by James Wylder)

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

657 - fixed crossfade points order (structure for big endian and little
658 endian systems was interchanged)
659 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

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

741 - added libgig.spec and libgig.pc package configurations for generating
742 Redhat packages
743 - header files included on installation.
744 - autotools-generated files removed from CVS repository.
745 - added support for generating Debian packages
746 - version of shared library can be set in configure.in
747
748 Version 0.7.0 (3 May 2004)
749
750 * general changes:
751 - various big endian specific corrections
752 (successfully tested now on PPC)
753 - minor adjustments to avoid compile errors on some systems
754 (using now pow() instead of powl() and --pedantic g++ compiler switch)
755 - libtoolized the library
756 - added man pages for the command line tools
757 (gigextract, gigdump, dlsdump, rifftree)
758
759 * src/gig.cpp, src/gig.h:
760 - fixed bug in decompression algorithm which caused it not to detect
761 the end of a stream
762 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
763 takes the MIDI key velocity value as an argument and returns the
764 appropriate volume factor (0.0 ... 1.0) for the sample to be played
765 back, the velocity curve transformation functions used for this are
766 only an approximation so far
767 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
768 'Sample::LoopSize' which reflected wrong values
769 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
770 measured in sample points instead of byte offset
771 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
772 'Sample::FineTune'
773 - added class attribute 'Sample::LoopSize'
774 - added method GetInstrument(uint index) to class 'File'
775 - added ReadAndLoop() method to class 'Sample' which is an extension to
776 the normal Read() method to honor the sample's looping information
777 while streaming from disk
778 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
779 'eg2_ctrl_t': replaced this huge enumeration by a structure which
780 reflects the MIDI controller number in case of an ordinary control
781 change controller (this saves a huge switch-case block in the
782 application of the library user)
783 - renamed following attributes in class 'DimensionRegion':
784 'AttenuationContol' -> 'AttenuationController',
785 'InvertAttenuationControl' -> 'InvertAttenuationController',
786 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
787 - minor fix in API documentation for method GetVelocityAttenuation() in
788 class 'DimensionRegion'
789
790 * src/RIFF.cpp, src/RIFF.h:
791 - added additional API documentation
792 - minor fix in Chunk::Read() method (only a minor efficiency issue)
793
794 * src/gigdump.cpp:
795 - added printout of samples' looping informations
796
797 Version 0.6.0 (3 Nov 2003)
798
799 * initial release
