File size: 40096 byte(s)
* src/helper.h: Fix compile error with GCC 9 due to ignored result value
  of vasprintf() function call.

* Bumped version (4.2.0.svn19).

1 schoenebeck 3623 Version SVN trunk (?)
2    
3     * general changes:
4     - Require at least a C++11 compliant compiler.
5 schoenebeck 3723 - Require some UUID generating function by underlying system.
6 schoenebeck 3623
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 schoenebeck 3710 - 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 schoenebeck 3645 - 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 schoenebeck 3656 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
30     (patch by Ivan Maguidhir).
31 schoenebeck 3657 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
32     (original patch by Ivan Maguidhir).
33 schoenebeck 3720 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
34     dimensions being in different order after deleting a dimension zone.
35 schoenebeck 3723 - Script: Generate a persistent UUID for each script.
36 schoenebeck 3731 - 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 schoenebeck 3799 - 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 schoenebeck 3623
47 schoenebeck 3770 * src/Serialization.cpp, src/Serialization.h:
48     - Fixed broken Archive(RawData) constructor which always threw an
49     Exception.
50 schoenebeck 3771 - 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 schoenebeck 3773 - 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 schoenebeck 3774 - Added new method Archive::operation() which allows applications to
55     distinguish between serialization vs. deserialization in their
56     serialize() method implementations.
57 schoenebeck 3775 - 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 schoenebeck 3776 - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
62     STL).
63 schoenebeck 3777 - 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 schoenebeck 3770
67 schoenebeck 3859 * src/helper.h:
68     - Fix compile error with GCC 9 due to ignored result value of vasprintf()
69     function call.
70    
71 schoenebeck 3623 * src/tools/gigdump.cpp:
72     - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
73     LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
74     LFO2FlipPhase and LFO3FlipPhase.
75    
76 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
77 schoenebeck 3392
78 schoenebeck 3476 * general changes:
79     - Added MSVC build support (anonymous patch from mailing list).
80     - Introduced CMake build support (yet constrained for building with MSVC)
81     (anonymous patch from mailing list).
82 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
83     destructors. Added new virtual method DeleteChunks() to those classes
84     for this which must be explicitly called instead to remove their RIFF
85     chunks.
86     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
87     of zero; which is unsafe per se.
88     - Added C++11 "override" keyword where appropriate.
89 schoenebeck 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
90     of their actions when not passing a progress_t callback structure.
91 schoenebeck 3476
92 schoenebeck 3398 * src/gig.cpp, src/gig.h:
93     - Fixed Doxygen API comments for enum types (currently latest Doxygen
94     [v1.8.13] only supports C comments in macro arguments expansion, but
95     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
96     the Doxygen source code, which currently also filter out new line
97     \n chars).
98 schoenebeck 3414 - Added new method File::CountSamples().
99     - Added new method File::CountInstruments().
100 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
101     (patch by Ivan Maguidhir).
102     - Added gig v4 version identifier (File::VERSION_4).
103 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
104     DimensionRegion::SustainReleaseTrigger which allows to define whether
105     a sustain pedal up event shall cause a release trigger sample to be
106     played (default: don't play release trigger sample by sustain pedal).
107 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
108     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
109     regular behaviour of playing release trigger sample on MIDI note-off
110     events.
111 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
112     (original patch by Ivan Maguidhir).
113 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).

115 schoenebeck 3398
116 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
117     - File: Fixed implicitly allocated RIFF::File object never been freed.
118 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
119     the respective classes for implementing (the old) UpdateChunks() and the
120     new DeleteChunks() method.
121 schoenebeck 3481 - Added File::GetRiffFile() method.
122 schoenebeck 3463
123 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
124     - Added Sample::GetFile() method.
125     - Added File::GetRiffFile() method.
126    
127 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
128     - Hide pure internal declarations from header file to avoid numerous
129     compiler warnings when building and linking against the public API.
130 persson 3454 - Fixed comparision logic bug
131 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
132 schoenebeck 3392
133 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
134     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
135     caused a resource leak
136 persson 3468 - Avoid compiler warning when building for 32 bit windows.
137 schoenebeck 3478 - Added new method progress_t::subdivide().
138 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
139     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
140     allows a more fine graded control into which portions the subtasks are
141     divided to.
142 schoenebeck 3412
143 schoenebeck 3425 * src/tools/gigdump.cpp:
144     - Added command line option --instrument-names which causes only
145     instrument names and their index numbers to be printed.
146    
147 schoenebeck 3370 Version 4.1.0 (25 Nov 2017)

155     in a portable, easy and flexible way.
156 schoenebeck 3173 - print compiler warning if no RTTI available
157 schoenebeck 3175 - Fixed potential crash in command line tools gig2stereo, korg2gig,

168 schoenebeck 2912 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
169 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
170     large monolithic file, otherwise if .gig file is < 2 GB check for
171     "extension" files (.gx01, .gx02, ...) instead.
172 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
173     if there were dimensions after the velocity dimension: it only created
174     valid velocity tables for cases of dimensions lower than the velocity
175     dimension.
176 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
177     a sample had been damaged for some reason
178     - Fix: samples' CRC checksums were damaged on file structure changes.
179 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
180     - Added new method Sample::GetWaveDataCRC32Checksum().
181 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
182 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
183 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.
184 schoenebeck 3117 - Fix: method File::AddContentOf() did not clone script groups and scripts
185     of passed original file.
186 schoenebeck 3138 - Added support for serializing & deserializing DimensionRegion
187     objects (and crossfade_t and leverage_ctrl_t objects).
188 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
189 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
190 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
191     textual format specifiers like with printf().
192     - On unknown leverage controller exception: show precise unknown leverage
193     controller number found.
194 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
195     console instead of throwing an exception.
196 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
197 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
198     extension to the gig file format, which allows to override the default
199     behavior of the first two EGs' state machines.
200 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
201     velocity curve parameters (fixes CVE-2017-12951).
202 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
203     pool index number (fixes CVE-2017-12954).
204 schoenebeck 2909
205 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
206     - Sample: wave pool offsets are now 64 bits (to allow support for files
207     larger than 4 GB).
208 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
209     textual format specifiers like with printf().
210 persson 3454
211 schoenebeck 2912 * src/RIFF.cpp, src/RIFF.h:
212     - added support for RIFF files larger than 4 GB, by default the required
213     internal RIFF file offset size is automatically detected (that is RIFF
214     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
215     automatically use 64 bit offsets), a particular offset size can be forced
216     with a new option added to the RIFF File constructor though
217     - when saving a modified, grown RIFF file, the temporary file size during
218     Save() operation will no longer be larger than the final grown file size
219 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
220     textual format specifiers like with printf().
221 schoenebeck 2912

229     - Archive: Added method valueAsString().
230     - Archive::rawData(): Automatically re-encode new raw data stream if
231     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
232 schoenebeck 3153 - Object: Added method memberByUID().
233     - Object: remove() method is now protected.
234 schoenebeck 3156 - Archive: Added method removeMember().
235     - Archive: Added methods name() and setName().
236     - Archive: Added methods comment() and setComment().
237     - Archive: Added methods timeStampCreated(), timeStampModified(),
238     dateTimeCreated() and dateTimeModified().
239 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
240 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
241     asLongDescr() and customTypeName(bool demangle=false)).
242 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
243     representations like "yes", "no", "true", "false" as expected.
244 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
245     textual format specifiers like with printf().
246 schoenebeck 3334 - DataType fix: Retain backward compatibility to older versions of native
247     C++ classes/structs.
248 schoenebeck 3150
249 schoenebeck 3369 * src/Akai.cpp:

257     - fixed c++11 narrowing warnings
258 schoenebeck 2909 - fixed fine tuning which was not translated at all
259 persson 2836
260 schoenebeck 2923 * src/tools/gigdump.cpp:
261     - additionally print VelocityUpperLimit and DimensionUpperLimits of all
262     dimension regions
263 schoenebeck 2984 - additionally print RIFF chunk file offset and RIFF chunk size of sample
264     data
265 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
266     the raw wave form data integrity of all samples
267     - added and implemented new parameter "--rebuild-checksums" which allows
268     to recalculate the CRC32 checksum of all samples' raw wave data and
269     rebuilding the gig file's global checksum table (i.e. in case the
270     file's checksum table was damaged)
271 schoenebeck 2989 - print samples' CRC32 checksums
272 schoenebeck 3323 - Print the new EG behavior options (eg_opt_t).

769 schoenebeck 220 * src/gigextract.cpp:
770     - added support for libsndfile (if libaudiofile and libsndfile are
771     available then libsndfile is preferred)
772    
773 schoenebeck 229 * src/gigdump.cpp:
774     - added printout for dimension informations (amount, type, bits, zones)
775 schoenebeck 231 - added printout for velocity response curve parameters
776 schoenebeck 235 - added printout for crossfade definitions
777 schoenebeck 269 - added printout for panorama value for each DimensionRegion
778 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
779     Gigasampler layers
780 schoenebeck 229
781 capela 168 Version 0.7.1 (2 Jul 2004)
782    
783     * packaging changes:
784 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
785     Redhat packages
786 capela 168 - header files included on installation.
787     - autotools-generated files removed from CVS repository.
788 schoenebeck 186 - added support for generating Debian packages
789     - version of shared library can be set in configure.in
790    
791 schoenebeck 58 Version 0.7.0 (3 May 2004)
792    
793     * general changes:
794     - various big endian specific corrections
795     (successfully tested now on PPC)
796     - minor adjustments to avoid compile errors on some systems
797     (using now pow() instead of powl() and --pedantic g++ compiler switch)
798     - libtoolized the library
799     - added man pages for the command line tools
800     (gigextract, gigdump, dlsdump, rifftree)
801    
802     * src/gig.cpp, src/gig.h:
803     - fixed bug in decompression algorithm which caused it not to detect
804     the end of a stream
805     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
806     takes the MIDI key velocity value as an argument and returns the
807     appropriate volume factor (0.0 ... 1.0) for the sample to be played
808     back, the velocity curve transformation functions used for this are
809     only an approximation so far
810     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
811     'Sample::LoopSize' which reflected wrong values
812     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
813     measured in sample points instead of byte offset
814     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
815     'Sample::FineTune'
816     - added class attribute 'Sample::LoopSize'
817     - added method GetInstrument(uint index) to class 'File'
818     - added ReadAndLoop() method to class 'Sample' which is an extension to
819     the normal Read() method to honor the sample's looping information
820     while streaming from disk
821     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
822     'eg2_ctrl_t': replaced this huge enumeration by a structure which
823     reflects the MIDI controller number in case of an ordinary control
824     change controller (this saves a huge switch-case block in the
825     application of the library user)
826     - renamed following attributes in class 'DimensionRegion':
827     'AttenuationContol' -> 'AttenuationController',
828     'InvertAttenuationControl' -> 'InvertAttenuationController',
829     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
830     - minor fix in API documentation for method GetVelocityAttenuation() in
831     class 'DimensionRegion'
832    
833     * src/RIFF.cpp, src/RIFF.h:
834     - added additional API documentation
835     - minor fix in Chunk::Read() method (only a minor efficiency issue)
836    
837     * src/gigdump.cpp:
838     - added printout of samples' looping informations
839    
840 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
841    
842     * initial release
