File size: 37818 byte(s)
* Compatibility fix (gig.cpp): GigaStudio 3 expects '3dnm' and '3ddp'
  RIFF chunks (original patch by Ivan Maguidhir).

* Bumped version (4.2.0.svn4).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Require at least a C++11 compliant compiler.
5
6 * src/gig.cpp, src/gig.h:
7 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
8 DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
9 allow to define override LFOs' wave form (e.g. saw or square instead of
10 the default wave form which was always sine in the original
11 Gigasampler/GigaStudio software).
12 - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
13 DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
14 move the start point horizontally of the LFOs' waves (0° ... 360°).
15 - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
16 (the original Gigasampler/GigaStudio software only had that flip phase
17 option for LFO1 and LFO2).
18 - Added method DimensionRegion::UsesAnyGigFormatExtension() (however only as
19 private method yet, see comments on method why).
20 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
21 implementations to enum vcf_type_t: vcf_type_lowpass_1p,
22 vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
23 vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
24 vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
25 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
26 (patch by Ivan Maguidhir).
27 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
28 (original patch by Ivan Maguidhir).
29
30 * src/tools/gigdump.cpp:
31 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
32 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
33 LFO2FlipPhase and LFO3FlipPhase.
34
35 Version 4.2.0 (25 Jul 2019)
36
37 * general changes:
38 - Added MSVC build support (anonymous patch from mailing list).
39 - Introduced CMake build support (yet constrained for building with MSVC)
40 (anonymous patch from mailing list).
41 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
42 destructors. Added new virtual method DeleteChunks() to those classes
43 for this which must be explicitly called instead to remove their RIFF
44 chunks.
45 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
46 of zero; which is unsafe per se.
47 - Added C++11 "override" keyword where appropriate.
48 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
49 of their actions when not passing a progress_t callback structure.
50
51 * src/gig.cpp, src/gig.h:
52 - Fixed Doxygen API comments for enum types (currently latest Doxygen
53 [v1.8.13] only supports C comments in macro arguments expansion, but
54 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
55 the Doxygen source code, which currently also filter out new line
56 \n chars).
57 - Added new method File::CountSamples().
58 - Added new method File::CountInstruments().
59 - Fixed gig v4 files falsely being handled as v2 format
60 (patch by Ivan Maguidhir).
61 - Added gig v4 version identifier (File::VERSION_4).
62 - GIG FORMAT EXTENSION: Added attribute
63 DimensionRegion::SustainReleaseTrigger which allows to define whether
64 a sustain pedal up event shall cause a release trigger sample to be
65 played (default: don't play release trigger sample by sustain pedal).
66 - GIG FORMAT EXTENSION: Added attribute
67 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
68 regular behaviour of playing release trigger sample on MIDI note-off
69 events.
70 - Introduced support for writing extension files (.gx01, .gx02, ...)
71 (original patch by Ivan Maguidhir).
72 - Many gig classes derive now from DLS::Storage (see DLS changes below).
73 - Added File::GetRiffFile() method.
74
75 * src/DLS.cpp, src/DLS.h:
76 - File: Fixed implicitly allocated RIFF::File object never been freed.
77 - Added new abstract interface base class DLS::Storage which is derived by
78 the respective classes for implementing (the old) UpdateChunks() and the
79 new DeleteChunks() method.
80 - Added File::GetRiffFile() method.
81
82 * src/sf2.cpp, src/sf2.h:
83 - Added Sample::GetFile() method.
84 - Added File::GetRiffFile() method.
85
86 * src/Serialization.cpp, src/Serialization.h:
87 - Hide pure internal declarations from header file to avoid numerous
88 compiler warnings when building and linking against the public API.
89 - Fixed comparision logic bug
90 - Fixed memory leak in DataType::customTypeName().
91
92 * src/RIFF.cpp, src/RIFF.h:
93 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
94 caused a resource leak
95 - Avoid compiler warning when building for 32 bit windows.
96 - Added new method progress_t::subdivide().
97 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
98 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
99 allows a more fine graded control into which portions the subtasks are
100 divided to.
101
102 * src/tools/gigdump.cpp:
103 - Added command line option --instrument-names which causes only
104 instrument names and their index numbers to be printed.
105
106 Version 4.1.0 (25 Nov 2017)
107 * general changes:
108 - removed 2 GB limitation when loading a gig or DLS file
109 - using now native integer size where appropriate
110 - fixed minor issues with man pages (patch by Debian maintainer)
111 - fixed various spelling mistakes (patch by Debian maintainer)
112 - Added new "Serialization" framework (and equally named namespace)
113 which allows to serialize and deserialize native C++ objects
114 in a portable, easy and flexible way.
115 - print compiler warning if no RTTI available
116 - Fixed potential crash in command line tools gig2stereo, korg2gig,
117 korgdump and sf2extract.
118 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
119 (original patch by Paul Brossier, slightly modified).
120 - Debian: Fixed packaging error about invalid substitution variable
121 "Source-Version".
122 - Raised Debian compatibility level to Debian 9 "Stretch".
123
124 * src/gig.cpp, src/gig.h:
125 - fixed bug in Script::SetGroup: the script chunk wasn't moved
126 - fixed compilation error with clang 3.4
127 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
128 as one single monolithic gig file. In case .gig file is >= 2GB expect a
129 large monolithic file, otherwise if .gig file is < 2 GB check for
130 "extension" files (.gx01, .gx02, ...) instead.
131 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
132 if there were dimensions after the velocity dimension: it only created
133 valid velocity tables for cases of dimensions lower than the velocity
134 dimension.
135 - added new method Sample::VerifyWaveData() which allows to check whether
136 a sample had been damaged for some reason
137 - Fix: samples' CRC checksums were damaged on file structure changes.
138 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
139 - Added new method Sample::GetWaveDataCRC32Checksum().
140 - Changed default value of EG2Release (filter release time) to 60s.
141 - Instruments' default pitch bend range is now +-2 semi tones.
142 - Fixed CRC checksums being wrong sometimes.
143 - Fix: method File::AddContentOf() did not clone script groups and scripts
144 of passed original file.
145 - Added support for serializing & deserializing DimensionRegion
146 objects (and crossfade_t and leverage_ctrl_t objects).
147 - Added enum reflection API functions for retrieving enum declaration type
148 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
149 - Exception class now has a variadic constructor which allows to add
150 textual format specifiers like with printf().
151 - On unknown leverage controller exception: show precise unknown leverage
152 controller number found.
153 - Ignore invalid leverage controller types and just show a warning on the
154 console instead of throwing an exception.
155 - Added new struct eg_opt_t and new class member variable
156 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
157 extension to the gig file format, which allows to override the default
158 behavior of the first two EGs' state machines.
159 - Fixed undefined behavior when loading a gig file with invalid
160 velocity curve parameters (fixes CVE-2017-12951).
161 - Fixed undefined behavior when loading a gig file with invalid wave
162 pool index number (fixes CVE-2017-12954).
163
164 * src/DLS.cpp, src/DLS.h:
165 - Sample: wave pool offsets are now 64 bits (to allow support for files
166 larger than 4 GB).
167 - Exception class now has a variadic constructor which allows to add
168 textual format specifiers like with printf().
169
170 * src/RIFF.cpp, src/RIFF.h:
171 - added support for RIFF files larger than 4 GB, by default the required
172 internal RIFF file offset size is automatically detected (that is RIFF
173 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
174 automatically use 64 bit offsets), a particular offset size can be forced
175 with a new option added to the RIFF File constructor though
176 - when saving a modified, grown RIFF file, the temporary file size during
177 Save() operation will no longer be larger than the final grown file size
178 - Exception class now has a variadic constructor which allows to add
179 textual format specifiers like with printf().
180
181 * src/Serialization.cpp, src/Serialization.h:
182 - Archive: Added method isModified().
183 - Archive: Added method setAutoValue().
184 - Archive: Added method setIntValue().
185 - Archive: Added method setRealValue().
186 - Archive: Added method setBoolValue().
187 - Archive: Added method setEnumValue().
188 - Archive: Added method valueAsString().
189 - Archive::rawData(): Automatically re-encode new raw data stream if
190 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
191 - Object: Added method memberByUID().
192 - Object: remove() method is now protected.
193 - Archive: Added method removeMember().
194 - Archive: Added methods name() and setName().
195 - Archive: Added methods comment() and setComment().
196 - Archive: Added methods timeStampCreated(), timeStampModified(),
197 dateTimeCreated() and dateTimeModified().
198 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
199 - DataType: Implemented demangling C++ type names (for methods
200 asLongDescr() and customTypeName(bool demangle=false)).
201 - Archive::setAutoValue(): Handle human readable boolean text
202 representations like "yes", "no", "true", "false" as expected.
203 - Exception class now has a variadic constructor which allows to add
204 textual format specifiers like with printf().
205 - DataType fix: Retain backward compatibility to older versions of native
206 C++ classes/structs.

224 - added and implemented new parameter "--verify" which allows to check
225 the raw wave form data integrity of all samples
226 - added and implemented new parameter "--rebuild-checksums" which allows
227 to recalculate the CRC32 checksum of all samples' raw wave data and
228 rebuilding the gig file's global checksum table (i.e. in case the
229 file's checksum table was damaged)
230 - print samples' CRC32 checksums
231 - Print the new EG behavior options (eg_opt_t).
232
233 * src/tools/gigextract.cpp:
234 - Fix: if sample name contains a path separator (slash or backslash) then
235 replace them by a minus sign to avoid file system issues.
236
237 * src/tools/gig2stereo.cpp:
238 - Also merge mono sample pairs with non matching loop information if
239 argument --incompatible was given.

321 (chunks at wrong location in the RIFF tree).
322 - Added new method Instrument::MoveTo() which allows to rearrange the order
323 of instruments within the same gig file.
324

395 length files, now throws a RIFF::Exception instead (fixes bug #121)
396 - bugfix: destructor for base class RIFF::Chunk accessed members
397 of derived class RIFF::File, which is bad, and caused crashes
398 when using Visual C++
399 - bugfix: files that contain zero length RIFF lists were not read
400 correctly (fixes #127) (bug was introduced 2009-03-13)

440 are saved when the file is written, even if they are empty.
441 - added missing parameter initalizations in sample, region and
442 instrument constructors
443 - clear unused fields when saving samples and regions
444 - fixed write support bugs: v3 dimension limits and chunksize
445 weren't saved, leverage controller of type controlchange
446 couldn't be saved, group name list chunk was placed wrong,
447 dimension region chunks also placed wrong

453 definition are now saved
454 - added constants for gig file versions
455 - write support: the 3crc and einf chunks are now created or
456 updated when a file is saved (3crc contains sample checksums,

458 - write support: DLSID is now generated on the file and the
459 instruments
460 - write support: improved the default values for dimension region
461 parameters
462 - more write support fixes: crossfade parameters were not saved,
463 v3 dimension limits were not correctly initialized and saved
464 when dimensions were added or deleted, v3 wave pool offsets were
465 not saved correctly
466 - write support: 24 bit samples can now be written
467 - write support: version 3 is now the default for new files
468 - more write support fixes: the 3ewg chunk is now bigger for v3,
469 dimension regions without mapped samples are now allowed, 3gnl
470 list in v3 files now always has 128 entries, several parameters
471 where incorrectly saved due to an operator precedence mistake
472 - DeleteSample now removes all references to the deleted sample
473 - AddDimension now copies all parameters from existing dimension
474 regions and also makes sure that the samplechannel dimension is
475 placed first in the list of dimensions.
476 - added method GetParent() to class 'DimensionRegion', which returns its
477 parent Region
478 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
479 unused areas
480 - added various setter methods to DimensionRegion class which take care
481 of updating lookup tables / caches.
482
483 * src/RIFF.cpp, src/RIFF.h:

503 group but moves all its members to another group, the other method,
504 that is File::DeleteGroup() now removes not just the group, but also
505 all the samples that belong to that group
506 - fixed crash which occured on interfering File::DeleteSample() and

510 with the group
511 - added Instrument::MoveRegion method
512 - fixed constructor for Region, which did not initialize correctly
513 when used from Instrument::AddRegion
514 - when saving, override the gig::Regions sample reference simply by
515 the region's first dimension region's sample (avoids an exception
516 when trying to save a new instrument)
517 - fixed AddDimension() method which did not fill out all mandatory
518 dimension definition fields
519
520 * src/DLS.cpp, src/DLS.h:
521 - added Instrument::MoveRegion method

523 causing an exception when trying to save a new instrument
524
525 * src/RIFF.cpp, src/RIFF.h:

580 - fixed the GetVelocityCutoff function, it wasn't always using the
581 VCFVelocityScale parameter when no cutoff controller was defined
582 - support for the gig v3 feature to have a number of dimension
583 splits not equal to a power of two
584 - added write support (highly experimental)

592 - added write support
593 - Chunk::LoadChunkData() can now be called again to resize the buffer
594 after a Chunk::Resize() and before the File::Save() call to allow

596 resize and write operations in one rush
597
598 * src/gigdump.cpp:
599 - fixed to show the correct amount of dimension regions instead of 32
600 (patch by James Wylder)

653 articulation informations are ignored at the moment
654 (patch by Andreas Persson)
655 - added some file format compatibility checks
656 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
657 never used, because the necessary check was made before

706
707 * packaging changes:
708 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
709 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix

711 SuSE and Fedora)
712 - fixed generation of Doxygen API documentation (now also included in
713 RPM and Debian packages)
714
715 * src/gig.cpp, src/gig.h:
716 - fixed / improved accuracy of all three velocity to volume
717 transformation functions a.k.a. 'nonlinear','linear','special'
718 (patch by Andreas Persson)
719 - denormals are filtered from the velocity to volume tables
720 - bugfix for dimension region switching (wrong handling of the release
721 trigger dimension, no bit range check for dimensions of split type
722 'split_type_bit')

745 - header files included on installation.
746 - autotools-generated files removed from CVS repository.
747 - added support for generating Debian packages
748 - version of shared library can be set in configure.in
749
750 Version 0.7.0 (3 May 2004)
751
752 * general changes:
753 - various big endian specific corrections
754 (successfully tested now on PPC)
755 - minor adjustments to avoid compile errors on some systems
756 (using now pow() instead of powl() and --pedantic g++ compiler switch)
757 - libtoolized the library
758 - added man pages for the command line tools
759 (gigextract, gigdump, dlsdump, rifftree)
760
761 * src/gig.cpp, src/gig.h:
762 - fixed bug in decompression algorithm which caused it not to detect
763 the end of a stream
764 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
765 takes the MIDI key velocity value as an argument and returns the
766 appropriate volume factor (0.0 ... 1.0) for the sample to be played
767 back, the velocity curve transformation functions used for this are
768 only an approximation so far
769 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
770 'Sample::LoopSize' which reflected wrong values
771 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
772 measured in sample points instead of byte offset
773 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
774 'Sample::FineTune'
775 - added class attribute 'Sample::LoopSize'
776 - added method GetInstrument(uint index) to class 'File'
777 - added ReadAndLoop() method to class 'Sample' which is an extension to
778 the normal Read() method to honor the sample's looping information
779 while streaming from disk
780 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
781 'eg2_ctrl_t': replaced this huge enumeration by a structure which
782 reflects the MIDI controller number in case of an ordinary control
783 change controller (this saves a huge switch-case block in the
784 application of the library user)
785 - renamed following attributes in class 'DimensionRegion':
786 'AttenuationContol' -> 'AttenuationController',
787 'InvertAttenuationControl' -> 'InvertAttenuationController',
788 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
789 - minor fix in API documentation for method GetVelocityAttenuation() in
790 class 'DimensionRegion'
791
792 * src/RIFF.cpp, src/RIFF.h:
793 - added additional API documentation
794 - minor fix in Chunk::Read() method (only a minor efficiency issue)
795
796 * src/gigdump.cpp:
797 - added printout of samples' looping informations
798
799 Version 0.6.0 (3 Nov 2003)
800
801 * initial release
