10          entire gig.cpp file.
11        - Use GetSubListAt() instead of GetFirstSubList() / GetNextSubList() in
12          entire gig.cpp file.
13    
14      * src/SF.cpp, src/SF.h:
15        - File::DeleteInstrument(): Fix clang sanatizer warning.
16    
17      * src/DLS.cpp, src/DLS.h:

29          each thread.
30        - Added method List::GetSubChunkAt().
31        - Added method List::GetSubListAt().

36    
37    Version 4.3.0 (9 May 2021)
38    
39      * general changes:
40        - Require at least a C++11 compliant compiler.
41        - Require some UUID generating function by underlying system.
42    
43      * src/gig.cpp, src/gig.h:
44        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
45          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
46          allow to define override LFOs' wave form (e.g. saw or square instead of
47          the default wave form which was always sine in the original
48          Gigasampler/GigaStudio software).
49        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
50          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
51          move the start point horizontally of the LFOs' waves (0° ... 360°).
52        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
53          (the original Gigasampler/GigaStudio software only had that flip phase
54          option for LFO1 and LFO2).
55        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
56          Region::UsesAnyGigFormatExtension(),
57          Instrument::UsesAnyGigFormatExtension() and
58          File::UsesAnyGigFormatExtension() (however only as private methods yet,
59          see comments on methods why).
60        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
61          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
62          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
63          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
64          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
65        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
66          (patch by Ivan Maguidhir).
67        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
68          (original patch by Ivan Maguidhir).
69        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
70          dimensions being in different order after deleting a dimension zone.
71        - Script: Generate a persistent UUID for each script.
72        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
73          accordingly added new methods to Instrument class:
74          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
75          GetScriptPatchVariable(), SetScriptPatchVariable(),
76          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
77          as child of our '3LS ' list chunk on Instrument level.
78        - Fixed undefined behaviour when modifying script slots on an instrument
79          that had been cloned and not been saved yet (e.g. unintended modification
80          of original instrument's script slots, and crash on Instrument destruction
81          due to double free of pScriptRefs).
82    
83      * src/Serialization.cpp, src/Serialization.h:
84        - Fixed broken Archive(RawData) constructor which always threw an
85          Exception.
86        - Added built-in support for C++ String objects (a.k.a. std::string
87          from the STL) and bumped Srx format version to 1.1 for that reason.
88        - Fixed assertion fault on some systems if a member variable defined was
89          serialized which was declared as size_t or ssize_t data type.
90        - Added new method Archive::operation() which allows applications to
91          distinguish between serialization vs. deserialization in their
92          serialize() method implementations.
93        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
94          the STL).
95        - Member offsets are now signed and for (newly added support of) member
96          variables on the heap -1 is always used as offset instead.
97        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
98          STL).
99        - DataType: Added optional 2nd custom type name.
100        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
101          STL).
102    
103      * src/helper.h:
104        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
105          function call.
106    
107      * src/tools/gigdump.cpp:
108        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
109          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
110          LFO2FlipPhase and LFO3FlipPhase.
111    
112    Version 4.2.0 (25 Jul 2019)
113    
114      * general changes:
115        - Added MSVC build support (anonymous patch from mailing list).
116        - Introduced CMake build support (yet constrained for building with MSVC)
117          (anonymous patch from mailing list).
118        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
119          destructors. Added new virtual method DeleteChunks() to those classes
120          for this which must be explicitly called instead to remove their RIFF
121          chunks.
122        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
123          of zero; which is unsafe per se.
124        - Added C++11 "override" keyword where appropriate.
125        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
126          of their actions when not passing a progress_t callback structure.
127    
128      * src/gig.cpp, src/gig.h:
129        - Fixed Doxygen API comments for enum types (currently latest Doxygen
130          [v1.8.13] only supports C comments in macro arguments expansion, but
131          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
132          the Doxygen source code, which currently also filter out new line
133          \n chars).
134        - Added new method File::CountSamples().
135        - Added new method File::CountInstruments().
136        - Fixed gig v4 files falsely being handled as v2 format
137          (patch by Ivan Maguidhir).
138        - Added gig v4 version identifier (File::VERSION_4).
139        - GIG FORMAT EXTENSION: Added attribute
140          DimensionRegion::SustainReleaseTrigger which allows to define whether
141          a sustain pedal up event shall cause a release trigger sample to be
142          played (default: don't play release trigger sample by sustain pedal).
143        - GIG FORMAT EXTENSION: Added attribute
144          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
145          regular behaviour of playing release trigger sample on MIDI note-off
146          events.
147        - Introduced support for writing extension files (.gx01, .gx02, ...)
148          (original patch by Ivan Maguidhir).
149        - Many gig classes derive now from DLS::Storage (see DLS changes below).
150        - Added File::GetRiffFile() method.
151    
152      * src/DLS.cpp, src/DLS.h:
153        - File: Fixed implicitly allocated RIFF::File object never been freed.
154        - Added new abstract interface base class DLS::Storage which is derived by
155          the respective classes for implementing (the old) UpdateChunks() and the
156          new DeleteChunks() method.
157        - Added File::GetRiffFile() method.
158    
159      * src/sf2.cpp, src/sf2.h:
160        - Added Sample::GetFile() method.
161        - Added File::GetRiffFile() method.
162    
163      * src/Serialization.cpp, src/Serialization.h:
164        - Hide pure internal declarations from header file to avoid numerous
165          compiler warnings when building and linking against the public API.
166        - Fixed comparision logic bug
167        - Fixed memory leak in DataType::customTypeName().
168    
169      * src/RIFF.cpp, src/RIFF.h:
170        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
171          caused a resource leak
172        - Avoid compiler warning when building for 32 bit windows.
173        - Added new method progress_t::subdivide().
174        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
175        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
176          allows a more fine graded control into which portions the subtasks are
177          divided to.
178    
179      * src/tools/gigdump.cpp:
180        - Added command line option --instrument-names which causes only
181          instrument names and their index numbers to be printed.
182    
183    Version 4.1.0 (25 Nov 2017)
184      * general changes:
185        - removed 2 GB limitation when loading a gig or DLS file
186        - using now native integer size where appropriate
187        - fixed minor issues with man pages (patch by Debian maintainer)
188        - fixed various spelling mistakes (patch by Debian maintainer)
189        - Added new "Serialization" framework (and equally named namespace)
190          which allows to serialize and deserialize native C++ objects
191          in a portable, easy and flexible way.
192        - print compiler warning if no RTTI available
193        - Fixed potential crash in command line tools gig2stereo, korg2gig,
194          korgdump and sf2extract.
195        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
196          (original patch by Paul Brossier, slightly modified).
197        - Debian: Fixed packaging error about invalid substitution variable
198          "Source-Version".
199        - Raised Debian compatibility level to Debian 9 "Stretch".
200    
201      * src/gig.cpp, src/gig.h:
202        - fixed bug in Script::SetGroup: the script chunk wasn't moved
203        - fixed compilation error with clang 3.4
204        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
205          as one single monolithic gig file. In case .gig file is >= 2GB expect a
206          large monolithic file, otherwise if .gig file is < 2 GB check for
207          "extension" files (.gx01, .gx02, ...) instead.
208        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
209          if there were dimensions after the velocity dimension: it only created
210          valid velocity tables for cases of dimensions lower than the velocity
211          dimension.
212        - added new method Sample::VerifyWaveData() which allows to check whether
213          a sample had been damaged for some reason
214        - Fix: samples' CRC checksums were damaged on file structure changes.
215        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
216        - Added new method Sample::GetWaveDataCRC32Checksum().
217        - Changed default value of EG2Release (filter release time) to 60s.
218        - Instruments' default pitch bend range is now +-2 semi tones.
219        - Fixed CRC checksums being wrong sometimes.
220        - Fix: method File::AddContentOf() did not clone script groups and scripts
221          of passed original file.
222        - Added support for serializing & deserializing DimensionRegion
223          objects (and crossfade_t and leverage_ctrl_t objects).
224        - Added enum reflection API functions for retrieving enum declaration type
225          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
226        - Exception class now has a variadic constructor which allows to add
227          textual format specifiers like with printf().
228        - On unknown leverage controller exception: show precise unknown leverage
229          controller number found.
230        - Ignore invalid leverage controller types and just show a warning on the
231          console instead of throwing an exception.
232        - Added new struct eg_opt_t and new class member variable
233          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
234          extension to the gig file format, which allows to override the default
235          behavior of the first two EGs' state machines.
236        - Fixed undefined behavior when loading a gig file with invalid
237          velocity curve parameters (fixes CVE-2017-12951).
238        - Fixed undefined behavior when loading a gig file with invalid wave
239          pool index number (fixes CVE-2017-12954).
240    
241      * src/DLS.cpp, src/DLS.h:
242        - Sample: wave pool offsets are now 64 bits (to allow support for files
243          larger than 4 GB).
244        - Exception class now has a variadic constructor which allows to add
245          textual format specifiers like with printf().
246    
247      * src/RIFF.cpp, src/RIFF.h:
248        - added support for RIFF files larger than 4 GB, by default the required
249          internal RIFF file offset size is automatically detected (that is RIFF
250          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
251          automatically use 64 bit offsets), a particular offset size can be forced
252          with a new option added to the RIFF File constructor though
253        - when saving a modified, grown RIFF file, the temporary file size during
254          Save() operation will no longer be larger than the final grown file size
255        - Exception class now has a variadic constructor which allows to add
256          textual format specifiers like with printf().
257    
258      * src/Serialization.cpp, src/Serialization.h:
259        - Archive: Added method isModified().
260        - Archive: Added method setAutoValue().
261        - Archive: Added method setIntValue().
262        - Archive: Added method setRealValue().
263        - Archive: Added method setBoolValue().
264        - Archive: Added method setEnumValue().
265        - Archive: Added method valueAsString().
266        - Archive::rawData(): Automatically re-encode new raw data stream if
267          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
268        - Object: Added method memberByUID().
269        - Object: remove() method is now protected.
270        - Archive: Added method removeMember().
271        - Archive: Added methods name() and setName().
272        - Archive: Added methods comment() and setComment().
273        - Archive: Added methods timeStampCreated(), timeStampModified(),
274          dateTimeCreated() and dateTimeModified().
275        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
276        - DataType: Implemented demangling C++ type names (for methods
277          asLongDescr() and customTypeName(bool demangle=false)).
278        - Archive::setAutoValue(): Handle human readable boolean text
279          representations like "yes", "no", "true", "false" as expected.
280        - Exception class now has a variadic constructor which allows to add
281          textual format specifiers like with printf().
282        - DataType fix: Retain backward compatibility to older versions of native
283          C++ classes/structs.
284    
285      * src/Akai.cpp:
286        - Fixed compilation error with recent, more strict compilers.
287    
288      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

291    
292      * src/tools/korg2gig.cpp:
293        - fixed c++11 narrowing warnings
294        - fixed fine tuning which was not translated at all
295    
296      * src/tools/gigdump.cpp:
297        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
298          dimension regions
299        - additionally print RIFF chunk file offset and RIFF chunk size of sample
300          data
301        - added and implemented new parameter "--verify" which allows to check
302          the raw wave form data integrity of all samples
303        - added and implemented new parameter "--rebuild-checksums" which allows
304          to recalculate the CRC32 checksum of all samples' raw wave data and
305          rebuilding the gig file's global checksum table (i.e. in case the
306          file's checksum table was damaged)
307        - print samples' CRC32 checksums
308        - Print the new EG behavior options (eg_opt_t).
309    
310      * src/tools/gigextract.cpp:
311        - Fix: if sample name contains a path separator (slash or backslash) then
312          replace them by a minus sign to avoid file system issues.
313    
314      * src/tools/gig2stereo.cpp:
315        - Also merge mono sample pairs with non matching loop information if
316          argument --incompatible was given.
317    
318      * packaging changes:
319        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
320          auto detect whether it (sh/c)ould output its messages in color.
