9    
10      * src/SF.cpp, src/SF.h:
11        - File::DeleteInstrument(): Fix clang sanatizer warning.
12    
13      * src/DLS.cpp, src/DLS.h:
14        - Use GetSubChunkAt() instead of GetFirstSubChunk() / GetNextSubChunk() in

32    
33    Version 4.3.0 (9 May 2021)
34    
35      * general changes:
36        - Require at least a C++11 compliant compiler.
37        - Require some UUID generating function by underlying system.
38    
39      * src/gig.cpp, src/gig.h:
40        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
41          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
42          allow to define override LFOs' wave form (e.g. saw or square instead of
43          the default wave form which was always sine in the original
44          Gigasampler/GigaStudio software).
45        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
46          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
47          move the start point horizontally of the LFOs' waves (0° ... 360°).
48        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
49          (the original Gigasampler/GigaStudio software only had that flip phase
50          option for LFO1 and LFO2).
51        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
52          Region::UsesAnyGigFormatExtension(),
53          Instrument::UsesAnyGigFormatExtension() and
54          File::UsesAnyGigFormatExtension() (however only as private methods yet,
55          see comments on methods why).
56        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
57          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
58          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
59          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
60          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
61        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
62          (patch by Ivan Maguidhir).
63        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
64          (original patch by Ivan Maguidhir).
65        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
66          dimensions being in different order after deleting a dimension zone.
67        - Script: Generate a persistent UUID for each script.
68        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
69          accordingly added new methods to Instrument class:
70          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
71          GetScriptPatchVariable(), SetScriptPatchVariable(),
72          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
73          as child of our '3LS ' list chunk on Instrument level.
74        - Fixed undefined behaviour when modifying script slots on an instrument
75          that had been cloned and not been saved yet (e.g. unintended modification
76          of original instrument's script slots, and crash on Instrument destruction
77          due to double free of pScriptRefs).
78    
79      * src/Serialization.cpp, src/Serialization.h:
80        - Fixed broken Archive(RawData) constructor which always threw an
81          Exception.
82        - Added built-in support for C++ String objects (a.k.a. std::string
83          from the STL) and bumped Srx format version to 1.1 for that reason.
84        - Fixed assertion fault on some systems if a member variable defined was
85          serialized which was declared as size_t or ssize_t data type.
86        - Added new method Archive::operation() which allows applications to
87          distinguish between serialization vs. deserialization in their
88          serialize() method implementations.
89        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
90          the STL).
91        - Member offsets are now signed and for (newly added support of) member
92          variables on the heap -1 is always used as offset instead.
93        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
94          STL).
95        - DataType: Added optional 2nd custom type name.
96        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
97          STL).
98    
99      * src/helper.h:
100        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
101          function call.
102    
103      * src/tools/gigdump.cpp:
104        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
105          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
106          LFO2FlipPhase and LFO3FlipPhase.
107    
108    Version 4.2.0 (25 Jul 2019)
109    
110      * general changes:
111        - Added MSVC build support (anonymous patch from mailing list).
112        - Introduced CMake build support (yet constrained for building with MSVC)
113          (anonymous patch from mailing list).
114        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
115          destructors. Added new virtual method DeleteChunks() to those classes
116          for this which must be explicitly called instead to remove their RIFF
117          chunks.
118        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
119          of zero; which is unsafe per se.
120        - Added C++11 "override" keyword where appropriate.
121        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
122          of their actions when not passing a progress_t callback structure.
123    
124      * src/gig.cpp, src/gig.h:
125        - Fixed Doxygen API comments for enum types (currently latest Doxygen
126          [v1.8.13] only supports C comments in macro arguments expansion, but
127          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
128          the Doxygen source code, which currently also filter out new line
129          \n chars).
130        - Added new method File::CountSamples().
131        - Added new method File::CountInstruments().
132        - Fixed gig v4 files falsely being handled as v2 format
133          (patch by Ivan Maguidhir).
134        - Added gig v4 version identifier (File::VERSION_4).
135        - GIG FORMAT EXTENSION: Added attribute
136          DimensionRegion::SustainReleaseTrigger which allows to define whether
137          a sustain pedal up event shall cause a release trigger sample to be
138          played (default: don't play release trigger sample by sustain pedal).
139        - GIG FORMAT EXTENSION: Added attribute
140          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
141          regular behaviour of playing release trigger sample on MIDI note-off
142          events.
143        - Introduced support for writing extension files (.gx01, .gx02, ...)
144          (original patch by Ivan Maguidhir).
145        - Many gig classes derive now from DLS::Storage (see DLS changes below).
146        - Added File::GetRiffFile() method.
147    
148      * src/DLS.cpp, src/DLS.h:
149        - File: Fixed implicitly allocated RIFF::File object never been freed.
150        - Added new abstract interface base class DLS::Storage which is derived by
151          the respective classes for implementing (the old) UpdateChunks() and the
152          new DeleteChunks() method.
153        - Added File::GetRiffFile() method.
154    
155      * src/sf2.cpp, src/sf2.h:
156        - Added Sample::GetFile() method.
157        - Added File::GetRiffFile() method.
158    
159      * src/Serialization.cpp, src/Serialization.h:
160        - Hide pure internal declarations from header file to avoid numerous
161          compiler warnings when building and linking against the public API.
162        - Fixed comparision logic bug
163        - Fixed memory leak in DataType::customTypeName().
164    
165      * src/RIFF.cpp, src/RIFF.h:
166        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
167          caused a resource leak
168        - Avoid compiler warning when building for 32 bit windows.
169        - Added new method progress_t::subdivide().
170        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
171        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
172          allows a more fine graded control into which portions the subtasks are
173          divided to.
174    
175      * src/tools/gigdump.cpp:
176        - Added command line option --instrument-names which causes only
177          instrument names and their index numbers to be printed.
178    
179    Version 4.1.0 (25 Nov 2017)
180      * general changes:
181        - removed 2 GB limitation when loading a gig or DLS file
182        - using now native integer size where appropriate
183        - fixed minor issues with man pages (patch by Debian maintainer)
184        - fixed various spelling mistakes (patch by Debian maintainer)
185        - Added new "Serialization" framework (and equally named namespace)
186          which allows to serialize and deserialize native C++ objects
187          in a portable, easy and flexible way.
188        - print compiler warning if no RTTI available
189        - Fixed potential crash in command line tools gig2stereo, korg2gig,
190          korgdump and sf2extract.
191        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
192          (original patch by Paul Brossier, slightly modified).

194          "Source-Version".
195        - Raised Debian compatibility level to Debian 9 "Stretch".
196    
197      * src/gig.cpp, src/gig.h:
198        - fixed bug in Script::SetGroup: the script chunk wasn't moved
199        - fixed compilation error with clang 3.4
200        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
201          as one single monolithic gig file. In case .gig file is >= 2GB expect a
202          large monolithic file, otherwise if .gig file is < 2 GB check for
203          "extension" files (.gx01, .gx02, ...) instead.
204        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
205          if there were dimensions after the velocity dimension: it only created
206          valid velocity tables for cases of dimensions lower than the velocity
207          dimension.
208        - added new method Sample::VerifyWaveData() which allows to check whether
209          a sample had been damaged for some reason
210        - Fix: samples' CRC checksums were damaged on file structure changes.
211        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
212        - Added new method Sample::GetWaveDataCRC32Checksum().
213        - Changed default value of EG2Release (filter release time) to 60s.
214        - Instruments' default pitch bend range is now +-2 semi tones.
215        - Fixed CRC checksums being wrong sometimes.
216        - Fix: method File::AddContentOf() did not clone script groups and scripts
217          of passed original file.
218        - Added support for serializing & deserializing DimensionRegion
219          objects (and crossfade_t and leverage_ctrl_t objects).
220        - Added enum reflection API functions for retrieving enum declaration type
221          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
222        - Exception class now has a variadic constructor which allows to add
223          textual format specifiers like with printf().
224        - On unknown leverage controller exception: show precise unknown leverage
225          controller number found.
226        - Ignore invalid leverage controller types and just show a warning on the
227          console instead of throwing an exception.
228        - Added new struct eg_opt_t and new class member variable
229          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
230          extension to the gig file format, which allows to override the default
231          behavior of the first two EGs' state machines.
232        - Fixed undefined behavior when loading a gig file with invalid
233          velocity curve parameters (fixes CVE-2017-12951).
234        - Fixed undefined behavior when loading a gig file with invalid wave
235          pool index number (fixes CVE-2017-12954).
236    
237      * src/DLS.cpp, src/DLS.h:
238        - Sample: wave pool offsets are now 64 bits (to allow support for files
239          larger than 4 GB).
240        - Exception class now has a variadic constructor which allows to add
241          textual format specifiers like with printf().
242    
243      * src/RIFF.cpp, src/RIFF.h:
244        - added support for RIFF files larger than 4 GB, by default the required
245          internal RIFF file offset size is automatically detected (that is RIFF
246          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
247          automatically use 64 bit offsets), a particular offset size can be forced
248          with a new option added to the RIFF File constructor though
249        - when saving a modified, grown RIFF file, the temporary file size during
250          Save() operation will no longer be larger than the final grown file size
251        - Exception class now has a variadic constructor which allows to add
252          textual format specifiers like with printf().
253    
254      * src/Serialization.cpp, src/Serialization.h:
255        - Archive: Added method isModified().
256        - Archive: Added method setAutoValue().

259        - Archive: Added method setBoolValue().
260        - Archive: Added method setEnumValue().
261        - Archive: Added method valueAsString().
262        - Archive::rawData(): Automatically re-encode new raw data stream if
263          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
264        - Object: Added method memberByUID().
265        - Object: remove() method is now protected.
266        - Archive: Added method removeMember().
267        - Archive: Added methods name() and setName().
268        - Archive: Added methods comment() and setComment().
269        - Archive: Added methods timeStampCreated(), timeStampModified(),
270          dateTimeCreated() and dateTimeModified().
271        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
272        - DataType: Implemented demangling C++ type names (for methods
273          asLongDescr() and customTypeName(bool demangle=false)).
274        - Archive::setAutoValue(): Handle human readable boolean text
275          representations like "yes", "no", "true", "false" as expected.
276        - Exception class now has a variadic constructor which allows to add
277          textual format specifiers like with printf().
278        - DataType fix: Retain backward compatibility to older versions of native
279          C++ classes/structs.
280    
281      * src/Akai.cpp:
282        - Fixed compilation error with recent, more strict compilers.
283

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