File size: 37247 byte(s)
* Autoconf: require at least a C++11 compliant compiler.

* gig.cpp/.h: GIG FORMAT EXTENSION: Added attributes
  DimensionRegion::LFO1WaveForm, DimensionRegion::LFO2WaveForm and
  DimensionRegion::LFO3WaveForm, which allow to override LFOs'
  default wave form (e.g. saw or square instead of the default wave
  form which was always sine in the original Gigasampler/GigaStudio
  software).

* gig.cpp/.h: GIG FORMAT EXTENSION: Added attributes
  DimensionRegion::LFO1Phase, DimensionRegion::LFO2Phase and
  DimensionRegion::LFO3Phase, which allow to move the start point
  horizontally of the LFOs' waves on the time axis
  (0° ... 360°).

* gig.cpp/.h: GIG FORMAT EXTENSION: Added attribute
  DimensionRegion::LFO3FlipPhase (the original Gigasampler/GigaStudio
  software only had that flip phase option for LFO1 and LFO2).

* gig.cpp/.h: Added method DimensionRegion::UsesAnyGigFormatExtension()
  (however only as private method yet, see comments on method why).

* src/tools/gigdump.cpp: Print dimension region properties
  LFO1WaveForm, LFO2WaveForm, LFO3WaveForm, LFO1Phase, LFO2Phase,
  LFO3Phase, LFO1FlipPhase, LFO2FlipPhase and LFO3FlipPhase.

* Bumped version (4.2.0.svn1).

1 Version SVN trunk (?)

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).

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

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

269
270 * AKAI file format:
271 - Added Linux/POSIX ported version of libakai. Note that libakai is released
272 under LGPL terms while libgig is released under GPL terms. To handle this
273 license difference appropriately the AKAI support part is built as
274 separate DLL (.so file).
275 - Fixed Mac OSX support so that the Akai lib files and tools compile without
276 any exotic third party libraries.

310 - Bugfix: Adding a new region in between two existing regions caused the
311 new one being dropped after save operation and the gig file being tainted
312 (chunks at wrong location in the RIFF tree).
313 - Added new method Instrument::MoveTo() which allows to rearrange the order
314 of instruments within the same gig file.
315

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

432 - added missing parameter initalizations in sample, region and
433 instrument constructors
434 - clear unused fields when saving samples and regions
435 - fixed write support bugs: v3 dimension limits and chunksize

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

495 that is File::DeleteGroup() now removes not just the group, but also
496 all the samples that belong to that group
497 - fixed crash which occured on interfering File::DeleteSample() and
498 File::GetNextSample() calls (due to iterator invalidation)

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

644 articulation informations are ignored at the moment
645 (patch by Andreas Persson)
646 - added some file format compatibility checks
647 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

702 SuSE and Fedora)
703 - fixed generation of Doxygen API documentation (now also included in
704 RPM and Debian packages)
705
706 * src/gig.cpp, src/gig.h:
707 - fixed / improved accuracy of all three velocity to volume
708 transformation functions a.k.a. 'nonlinear','linear','special'
709 (patch by Andreas Persson)
710 - denormals are filtered from the velocity to volume tables
711 - bugfix for dimension region switching (wrong handling of the release
712 trigger dimension, no bit range check for dimensions of split type

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