Fri Jan 10 13:32:34 2020 UTC (4 years, 2 months ago) by schoenebeck
File size: 38073 byte(s)
* gig.cpp: Added methods Region::UsesAnyGigFormatExtension(),
  Instrument::UsesAnyGigFormatExtension() and
  File::UsesAnyGigFormatExtension() (as private methods for
  now, see comments on methods for reason why).

* gig.cpp: Only write pure-GSt-compatibility RIFF chunks
  introduced by SVN r3657 if the file is not using any of
  our gig format extensions anyway.

* Bumped version (4.2.0.svn6).

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

229 - added and implemented new parameter "--verify" which allows to check
230 the raw wave form data integrity of all samples
231 - added and implemented new parameter "--rebuild-checksums" which allows
232 to recalculate the CRC32 checksum of all samples' raw wave data and
233 rebuilding the gig file's global checksum table (i.e. in case the
234 file's checksum table was damaged)
235 - print samples' CRC32 checksums
236 - Print the new EG behavior options (eg_opt_t).
237
238 * src/tools/gigextract.cpp:
239 - Fix: if sample name contains a path separator (slash or backslash) then
240 replace them by a minus sign to avoid file system issues.
241
242 * src/tools/gig2stereo.cpp:
243 - Also merge mono sample pairs with non matching loop information if
244 argument --incompatible was given.
245

283
284 * AKAI file format:
285 - Added Linux/POSIX ported version of libakai. Note that libakai is released
286 under LGPL terms while libgig is released under GPL terms. To handle this

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

446 - added missing parameter initalizations in sample, region and
447 instrument constructors
448 - clear unused fields when saving samples and regions
449 - fixed write support bugs: v3 dimension limits and chunksize

458 definition are now saved
459 - added constants for gig file versions
460 - write support: the 3crc and einf chunks are now created or
461 updated when a file is saved (3crc contains sample checksums,
462 einf contains file statistics)
463 - write support: DLSID is now generated on the file and the
464 instruments
465 - write support: improved the default values for dimension region
466 parameters
467 - more write support fixes: crossfade parameters were not saved,
468 v3 dimension limits were not correctly initialized and saved
469 when dimensions were added or deleted, v3 wave pool offsets were
470 not saved correctly
471 - write support: 24 bit samples can now be written
472 - write support: version 3 is now the default for new files

474 dimension regions without mapped samples are now allowed, 3gnl
475 list in v3 files now always has 128 entries, several parameters
476 where incorrectly saved due to an operator precedence mistake
477 - DeleteSample now removes all references to the deleted sample
478 - AddDimension now copies all parameters from existing dimension
479 regions and also makes sure that the samplechannel dimension is
480 placed first in the list of dimensions.
481 - added method GetParent() to class 'DimensionRegion', which returns its
482 parent Region
483 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
484 unused areas
485 - added various setter methods to DimensionRegion class which take care
486 of updating lookup tables / caches.
487

509 that is File::DeleteGroup() now removes not just the group, but also
510 all the samples that belong to that group
511 - fixed crash which occured on interfering File::DeleteSample() and

515 with the group
516 - added Instrument::MoveRegion method
517 - fixed constructor for Region, which did not initialize correctly
518 when used from Instrument::AddRegion
519 - when saving, override the gig::Regions sample reference simply by
520 the region's first dimension region's sample (avoids an exception
521 when trying to save a new instrument)

523 dimension definition fields
524
525 * src/DLS.cpp, src/DLS.h:

658 articulation informations are ignored at the moment
659 (patch by Andreas Persson)
660 - added some file format compatibility checks
661 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
662 never used, because the necessary check was made before

711
712 * packaging changes:
713 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
714 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
715 - fixed man pages automake install rule (which didn't work on Mandrake,
716 SuSE and Fedora)
717 - fixed generation of Doxygen API documentation (now also included in
718 RPM and Debian packages)
719
720 * src/gig.cpp, src/gig.h:
721 - fixed / improved accuracy of all three velocity to volume
722 transformation functions a.k.a. 'nonlinear','linear','special'
723 (patch by Andreas Persson)
724 - denormals are filtered from the velocity to volume tables
725 - bugfix for dimension region switching (wrong handling of the release
726 trigger dimension, no bit range check for dimensions of split type
727 'split_type_bit')
728 - fixed panorama value in DimensionRegion (invalid conversion from
729 signed 7 bit to signed 8 bit)
730 - added class attribute 'Layers' to class 'gig::Region'
731 - symbol prototyping of gig::Region (fixes build failure with qsampler)
732

748 - added libgig.spec and libgig.pc package configurations for generating
749 Redhat packages
750 - header files included on installation.
751 - autotools-generated files removed from CVS repository.
752 - added support for generating Debian packages
753 - version of shared library can be set in configure.in
754
755 Version 0.7.0 (3 May 2004)
756
757 * general changes:
758 - various big endian specific corrections
759 (successfully tested now on PPC)
760 - minor adjustments to avoid compile errors on some systems
761 (using now pow() instead of powl() and --pedantic g++ compiler switch)
762 - libtoolized the library
763 - added man pages for the command line tools
764 (gigextract, gigdump, dlsdump, rifftree)
765
766 * src/gig.cpp, src/gig.h:
767 - fixed bug in decompression algorithm which caused it not to detect
768 the end of a stream
769 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
770 takes the MIDI key velocity value as an argument and returns the
771 appropriate volume factor (0.0 ... 1.0) for the sample to be played
772 back, the velocity curve transformation functions used for this are
773 only an approximation so far
774 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
775 'Sample::LoopSize' which reflected wrong values
776 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
777 measured in sample points instead of byte offset
778 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
779 'Sample::FineTune'
780 - added class attribute 'Sample::LoopSize'
781 - added method GetInstrument(uint index) to class 'File'
782 - added ReadAndLoop() method to class 'Sample' which is an extension to
783 the normal Read() method to honor the sample's looping information
784 while streaming from disk
785 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
786 'eg2_ctrl_t': replaced this huge enumeration by a structure which
787 reflects the MIDI controller number in case of an ordinary control
788 change controller (this saves a huge switch-case block in the
789 application of the library user)
790 - renamed following attributes in class 'DimensionRegion':
791 'AttenuationContol' -> 'AttenuationController',
792 'InvertAttenuationControl' -> 'InvertAttenuationController',
793 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
794 - minor fix in API documentation for method GetVelocityAttenuation() in
795 class 'DimensionRegion'
796
797 * src/RIFF.cpp, src/RIFF.h:
798 - added additional API documentation
799 - minor fix in Chunk::Read() method (only a minor efficiency issue)
800
801 * src/gigdump.cpp:
802 - added printout of samples' looping informations
803
804 Version 0.6.0 (3 Nov 2003)
805
806 * initial release
