File size: 39232 byte(s)
* Serialization.cpp/.h: Added new method Archive::operation() which
  allows applications to distinguish between serialization vs.
  deserialization in their serialize() method implementations.

* Bumped version (4.2.0.svn12).

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 3623
43 schoenebeck 3770 * src/Serialization.cpp, src/Serialization.h:
44     - Fixed broken Archive(RawData) constructor which always threw an
45     Exception.
46 schoenebeck 3771 - Added built-in support for C++ String objects (a.k.a. std::string
47     from the STL) and bumped Srx format version to 1.1 for that reason.
48 schoenebeck 3773 - Fixed assertion fault on some systems if a member variable defined was
49     serialized which was declared as size_t or ssize_t data type.
50 schoenebeck 3774 - Added new method Archive::operation() which allows applications to
51     distinguish between serialization vs. deserialization in their
52     serialize() method implementations.
53 schoenebeck 3770
54 schoenebeck 3623 * src/tools/gigdump.cpp:
55     - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
56     LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
57     LFO2FlipPhase and LFO3FlipPhase.
58    
59 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
60 schoenebeck 3392
61 schoenebeck 3476 * general changes:
62     - Added MSVC build support (anonymous patch from mailing list).
63     - Introduced CMake build support (yet constrained for building with MSVC)
64     (anonymous patch from mailing list).
65 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
66     destructors. Added new virtual method DeleteChunks() to those classes
67     for this which must be explicitly called instead to remove their RIFF
68     chunks.
69     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
70     of zero; which is unsafe per se.
71     - Added C++11 "override" keyword where appropriate.
72 schoenebeck 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
73     of their actions when not passing a progress_t callback structure.
74 schoenebeck 3476
75 schoenebeck 3398 * src/gig.cpp, src/gig.h:
76     - Fixed Doxygen API comments for enum types (currently latest Doxygen
77     [v1.8.13] only supports C comments in macro arguments expansion, but
78     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
79     the Doxygen source code, which currently also filter out new line
80     \n chars).
81 schoenebeck 3414 - Added new method File::CountSamples().
82     - Added new method File::CountInstruments().
83 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
84     (patch by Ivan Maguidhir).
85     - Added gig v4 version identifier (File::VERSION_4).
86 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
87     DimensionRegion::SustainReleaseTrigger which allows to define whether
88     a sustain pedal up event shall cause a release trigger sample to be
89     played (default: don't play release trigger sample by sustain pedal).
90 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
91     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
92     regular behaviour of playing release trigger sample on MIDI note-off
93     events.
94 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
95     (original patch by Ivan Maguidhir).
96 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).
97 schoenebeck 3481 - Added File::GetRiffFile() method.
98 schoenebeck 3398
99 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
100     - File: Fixed implicitly allocated RIFF::File object never been freed.
101 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
102     the respective classes for implementing (the old) UpdateChunks() and the
103     new DeleteChunks() method.
104 schoenebeck 3481 - Added File::GetRiffFile() method.
105 schoenebeck 3463
106 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
107     - Added Sample::GetFile() method.
108     - Added File::GetRiffFile() method.
109    
110 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
111     - Hide pure internal declarations from header file to avoid numerous
112     compiler warnings when building and linking against the public API.
113 persson 3454 - Fixed comparision logic bug
114 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
115 schoenebeck 3392
116 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
117     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
118     caused a resource leak
119 persson 3468 - Avoid compiler warning when building for 32 bit windows.
120 schoenebeck 3478 - Added new method progress_t::subdivide().
121 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
122     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
123     allows a more fine graded control into which portions the subtasks are
124     divided to.
125 schoenebeck 3412
126 schoenebeck 3425 * src/tools/gigdump.cpp:
127     - Added command line option --instrument-names which causes only
128     instrument names and their index numbers to be printed.
129    
130 schoenebeck 3370 Version 4.1.0 (25 Nov 2017)

135 schoenebeck 3048 - fixed various spelling mistakes (patch by Debian maintainer)
136 schoenebeck 3138 - Added new "Serialization" framework (and equally named namespace)
137     which allows to serialize and deserialize native C++ objects
138     in a portable, easy and flexible way.
139 schoenebeck 3173 - print compiler warning if no RTTI available
140 schoenebeck 3175 - Fixed potential crash in command line tools gig2stereo, korg2gig,

152 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
153     large monolithic file, otherwise if .gig file is < 2 GB check for
154     "extension" files (.gx01, .gx02, ...) instead.
155 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
156     if there were dimensions after the velocity dimension: it only created
157     valid velocity tables for cases of dimensions lower than the velocity
158     dimension.
159 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
160     a sample had been damaged for some reason
161     - Fix: samples' CRC checksums were damaged on file structure changes.
162 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
163     - Added new method Sample::GetWaveDataCRC32Checksum().
164 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
165 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
166 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.

170     objects (and crossfade_t and leverage_ctrl_t objects).
171 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
172 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
173 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
174     textual format specifiers like with printf().
175     - On unknown leverage controller exception: show precise unknown leverage
176     controller number found.
177 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
178     console instead of throwing an exception.
179 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
180 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
181     extension to the gig file format, which allows to override the default
182     behavior of the first two EGs' state machines.
183 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
184     velocity curve parameters (fixes CVE-2017-12951).
185 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
186     pool index number (fixes CVE-2017-12954).
187 schoenebeck 2909
188 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
189     - Sample: wave pool offsets are now 64 bits (to allow support for files
190     larger than 4 GB).
191 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
192     textual format specifiers like with printf().
193 persson 3454
194 schoenebeck 2912 * src/RIFF.cpp, src/RIFF.h:
195     - added support for RIFF files larger than 4 GB, by default the required
196     internal RIFF file offset size is automatically detected (that is RIFF
197     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
198     automatically use 64 bit offsets), a particular offset size can be forced
199     with a new option added to the RIFF File constructor though
200     - when saving a modified, grown RIFF file, the temporary file size during
201     Save() operation will no longer be larger than the final grown file size
202 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
203     textual format specifiers like with printf().

213     - Archive::rawData(): Automatically re-encode new raw data stream if
214     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
215 schoenebeck 3153 - Object: Added method memberByUID().
216     - Object: remove() method is now protected.
217 schoenebeck 3156 - Archive: Added method removeMember().
218     - Archive: Added methods name() and setName().
219     - Archive: Added methods comment() and setComment().
220     - Archive: Added methods timeStampCreated(), timeStampModified(),
221     dateTimeCreated() and dateTimeModified().
222 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
223 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
224     asLongDescr() and customTypeName(bool demangle=false)).
225 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
226     representations like "yes", "no", "true", "false" as expected.
227 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
228     textual format specifiers like with printf().

242 persson 2836
243 schoenebeck 2923 * src/tools/gigdump.cpp:
244     - additionally print VelocityUpperLimit and DimensionUpperLimits of all
245     dimension regions
246 schoenebeck 2984 - additionally print RIFF chunk file offset and RIFF chunk size of sample
247     data
248 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
249     the raw wave form data integrity of all samples
250     - added and implemented new parameter "--rebuild-checksums" which allows
251     to recalculate the CRC32 checksum of all samples' raw wave data and
252     rebuilding the gig file's global checksum table (i.e. in case the
253     file's checksum table was damaged)
254 schoenebeck 2989 - print samples' CRC32 checksums
255 schoenebeck 3323 - Print the new EG behavior options (eg_opt_t).

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