# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Require at least a C++11 compliant compiler.
5        - Require some UUID generating function by underlying system.
6    
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        - 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        - 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        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
30          (patch by Ivan Maguidhir).
31        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
32          (original patch by Ivan Maguidhir).
33        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
34          dimensions being in different order after deleting a dimension zone.
35        - Script: Generate a persistent UUID for each script.
36        - 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        - 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    
47      * src/Serialization.cpp, src/Serialization.h:
48        - Fixed broken Archive(RawData) constructor which always threw an
49          Exception.
50        - 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        - 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        - Added new method Archive::operation() which allows applications to
55          distinguish between serialization vs. deserialization in their
56          serialize() method implementations.
57        - 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        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
62          STL).
63        - 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    
67      * src/tools/gigdump.cpp:
68        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
69          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
70          LFO2FlipPhase and LFO3FlipPhase.
71    
72    Version 4.2.0 (25 Jul 2019)
73    
74      * general changes:
75        - Added MSVC build support (anonymous patch from mailing list).
76        - Introduced CMake build support (yet constrained for building with MSVC)
77          (anonymous patch from mailing list).
78        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
79          destructors. Added new virtual method DeleteChunks() to those classes
80          for this which must be explicitly called instead to remove their RIFF
81          chunks.
82        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
83          of zero; which is unsafe per se.
84        - Added C++11 "override" keyword where appropriate.
85        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
86          of their actions when not passing a progress_t callback structure.
87    
88      * src/gig.cpp, src/gig.h:
89        - Fixed Doxygen API comments for enum types (currently latest Doxygen
90          [v1.8.13] only supports C comments in macro arguments expansion, but
91          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
92          the Doxygen source code, which currently also filter out new line
93          \n chars).
94        - Added new method File::CountSamples().
95        - Added new method File::CountInstruments().
96        - Fixed gig v4 files falsely being handled as v2 format
97          (patch by Ivan Maguidhir).
98        - Added gig v4 version identifier (File::VERSION_4).
99        - GIG FORMAT EXTENSION: Added attribute
100          DimensionRegion::SustainReleaseTrigger which allows to define whether
101          a sustain pedal up event shall cause a release trigger sample to be
102          played (default: don't play release trigger sample by sustain pedal).
103        - GIG FORMAT EXTENSION: Added attribute
104          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
105          regular behaviour of playing release trigger sample on MIDI note-off
106          events.
107        - Introduced support for writing extension files (.gx01, .gx02, ...)
108          (original patch by Ivan Maguidhir).
109        - Many gig classes derive now from DLS::Storage (see DLS changes below).
110        - Added File::GetRiffFile() method.
111    
112      * src/DLS.cpp, src/DLS.h:
113        - File: Fixed implicitly allocated RIFF::File object never been freed.
114        - Added new abstract interface base class DLS::Storage which is derived by
115          the respective classes for implementing (the old) UpdateChunks() and the
116          new DeleteChunks() method.
117        - Added File::GetRiffFile() method.
118    
119      * src/sf2.cpp, src/sf2.h:
120        - Added Sample::GetFile() method.
121        - Added File::GetRiffFile() method.
122    
123      * src/Serialization.cpp, src/Serialization.h:
124        - Hide pure internal declarations from header file to avoid numerous
125          compiler warnings when building and linking against the public API.
126        - Fixed comparision logic bug
127        - Fixed memory leak in DataType::customTypeName().
128    
129      * src/RIFF.cpp, src/RIFF.h:
130        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
131          caused a resource leak
132        - Avoid compiler warning when building for 32 bit windows.
133        - Added new method progress_t::subdivide().
134        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
135        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
136          allows a more fine graded control into which portions the subtasks are
137          divided to.
138    
139      * src/tools/gigdump.cpp:
140        - Added command line option --instrument-names which causes only
141          instrument names and their index numbers to be printed.
142    
143    Version 4.1.0 (25 Nov 2017)
144      * general changes:
145        - removed 2 GB limitation when loading a gig or DLS file
146        - using now native integer size where appropriate
147        - fixed minor issues with man pages (patch by Debian maintainer)
148        - fixed various spelling mistakes (patch by Debian maintainer)
149        - Added new "Serialization" framework (and equally named namespace)
150          which allows to serialize and deserialize native C++ objects
151          in a portable, easy and flexible way.
152        - print compiler warning if no RTTI available
153        - Fixed potential crash in command line tools gig2stereo, korg2gig,
154          korgdump and sf2extract.
155        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
156          (original patch by Paul Brossier, slightly modified).
157        - Debian: Fixed packaging error about invalid substitution variable
158          "Source-Version".
159        - Raised Debian compatibility level to Debian 9 "Stretch".
160    
161      * src/gig.cpp, src/gig.h:
162        - fixed bug in Script::SetGroup: the script chunk wasn't moved
163        - fixed compilation error with clang 3.4
164        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
165          as one single monolithic gig file. In case .gig file is >= 2GB expect a
166          large monolithic file, otherwise if .gig file is < 2 GB check for
167          "extension" files (.gx01, .gx02, ...) instead.
168        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
169          if there were dimensions after the velocity dimension: it only created
170          valid velocity tables for cases of dimensions lower than the velocity
171          dimension.
172        - added new method Sample::VerifyWaveData() which allows to check whether
173          a sample had been damaged for some reason
174        - Fix: samples' CRC checksums were damaged on file structure changes.
175        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
176        - Added new method Sample::GetWaveDataCRC32Checksum().
177        - Changed default value of EG2Release (filter release time) to 60s.
178        - Instruments' default pitch bend range is now +-2 semi tones.
179        - Fixed CRC checksums being wrong sometimes.
180        - Fix: method File::AddContentOf() did not clone script groups and scripts
181          of passed original file.
182        - Added support for serializing & deserializing DimensionRegion
183          objects (and crossfade_t and leverage_ctrl_t objects).
184        - Added enum reflection API functions for retrieving enum declaration type
185          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
186        - Exception class now has a variadic constructor which allows to add
187          textual format specifiers like with printf().
188        - On unknown leverage controller exception: show precise unknown leverage
189          controller number found.
190        - Ignore invalid leverage controller types and just show a warning on the
191          console instead of throwing an exception.
192        - Added new struct eg_opt_t and new class member variable
193          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
194          extension to the gig file format, which allows to override the default
195          behavior of the first two EGs' state machines.
196        - Fixed undefined behavior when loading a gig file with invalid
197          velocity curve parameters (fixes CVE-2017-12951).
198        - Fixed undefined behavior when loading a gig file with invalid wave
199          pool index number (fixes CVE-2017-12954).
200    
201      * src/DLS.cpp, src/DLS.h:
202        - Sample: wave pool offsets are now 64 bits (to allow support for files
203          larger than 4 GB).
204        - Exception class now has a variadic constructor which allows to add
205          textual format specifiers like with printf().
206    
207      * src/RIFF.cpp, src/RIFF.h:
208        - added support for RIFF files larger than 4 GB, by default the required
209          internal RIFF file offset size is automatically detected (that is RIFF
210          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
211          automatically use 64 bit offsets), a particular offset size can be forced
212          with a new option added to the RIFF File constructor though
213        - when saving a modified, grown RIFF file, the temporary file size during
214          Save() operation will no longer be larger than the final grown file size
215        - Exception class now has a variadic constructor which allows to add
216          textual format specifiers like with printf().
217    
218      * src/Serialization.cpp, src/Serialization.h:
219        - Archive: Added method isModified().
220        - Archive: Added method setAutoValue().
221        - Archive: Added method setIntValue().
222        - Archive: Added method setRealValue().
223        - Archive: Added method setBoolValue().
224        - Archive: Added method setEnumValue().
225        - Archive: Added method valueAsString().
226        - Archive::rawData(): Automatically re-encode new raw data stream if
227          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
228        - Object: Added method memberByUID().
229        - Object: remove() method is now protected.
230        - Archive: Added method removeMember().
231        - Archive: Added methods name() and setName().
232        - Archive: Added methods comment() and setComment().
233        - Archive: Added methods timeStampCreated(), timeStampModified(),
234          dateTimeCreated() and dateTimeModified().
235        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
236        - DataType: Implemented demangling C++ type names (for methods
237          asLongDescr() and customTypeName(bool demangle=false)).
238        - Archive::setAutoValue(): Handle human readable boolean text
239          representations like "yes", "no", "true", "false" as expected.
240        - Exception class now has a variadic constructor which allows to add
241          textual format specifiers like with printf().
242        - DataType fix: Retain backward compatibility to older versions of native
243          C++ classes/structs.
244    
245      * src/Akai.cpp:
246        - Fixed compilation error with recent, more strict compilers.
247    
248      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
249        - improved output of non-ascii characters in usage messages
250        - fixed printf format strings
251    
252      * src/tools/korg2gig.cpp:
253        - fixed c++11 narrowing warnings
254        - fixed fine tuning which was not translated at all
255    
256      * src/tools/gigdump.cpp:
257        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
258          dimension regions
259        - additionally print RIFF chunk file offset and RIFF chunk size of sample
260          data
261        - added and implemented new parameter "--verify" which allows to check
262          the raw wave form data integrity of all samples
263        - added and implemented new parameter "--rebuild-checksums" which allows
264          to recalculate the CRC32 checksum of all samples' raw wave data and
265          rebuilding the gig file's global checksum table (i.e. in case the
266          file's checksum table was damaged)
267        - print samples' CRC32 checksums
268        - Print the new EG behavior options (eg_opt_t).
269    
270      * src/tools/gigextract.cpp:
271        - Fix: if sample name contains a path separator (slash or backslash) then
272          replace them by a minus sign to avoid file system issues.
273    
274      * src/tools/gig2stereo.cpp:
275        - Also merge mono sample pairs with non matching loop information if
276          argument --incompatible was given.
277    
278      * packaging changes:
279        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
280          auto detect whether it (sh/c)ould output its messages in color.
281    
282    Version 4.0.0 (14 Jul 2015)

309        - fixed GetEG1Sustain which didn't return correct value
310        - bugfix: GetPan always returned -1, 0 or 1
311    
312      * KORG file format:
313        - initial support for sample based instruments in KORG's file format
314          (.KMP and .KSF files)
315    
316      * AKAI file format:
317        - Added Linux/POSIX ported version of libakai. Note that libakai is released
318          under LGPL terms while libgig is released under GPL terms. To handle this
319          license difference appropriately the AKAI support part is built as
320          separate DLL (.so file).

334        - added read and write support for Legato and Alternator midi
335          rules
336        - bugfix: sample groups were sometimes created multiple times or with
337          wrong textual group name
338        - added new method File::AddContentOf() for merging .gig files
339        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
340          controller types (only works with LinuxSampler & gigedit, will not
341          work with Gigasampler/GigaStudio)
342        - added new method File::GetGroup(String name) for getting group by name
343        - added new method Region::GetDimensionDefinition(dimension_t type)
344        - bugfix: don't alter region pointer in DimensionRegion::CopyAssign()

346        - added new method Region::DeleteDimensionZone(dimension_t, int)
347        - added new method Region::SplitDimensionZone(dimension_t, int)
348        - Fixed crash caused by Region::GetDimensionRegionByValue() that happened
349          with certain velocity split sounds under certain conditions (added bound
350          constraints to prevent that)

357          new one being dropped after save operation and the gig file being tainted
358          (chunks at wrong location in the RIFF tree).
359        - Added new method Instrument::MoveTo() which allows to rearrange the order
360          of instruments within the same gig file.
361    
362      * src/DLS.cpp, src/DLS.h:
363        - added new method File::GetFileName()
