File size: 33261 byte(s)
* src/RIFF.cpp: Fix: Calling File::SetMode() left an undefined file
  handle on Windows and caused a resource leak.
* Bumped version (4.1.0.svn3).

1 Version SVN trunk (?)
2
3 * src/gig.cpp, src/gig.h:
4 - Fixed Doxygen API comments for enum types (currently latest Doxygen
5 [v1.8.13] only supports C comments in macro arguments expansion, but
6 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
7 the Doxygen source code, which currently also filter out new line
8 \n chars).
9
10 * src/Serialization.cpp, src/Serialization.h:
11 - Hide pure internal declarations from header file to avoid numerous
12 compiler warnings when building and linking against the public API.
13
14 * src/RIFF.cpp, src/RIFF.h:
15 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
16 caused a resource leak
17
18 Version 4.1.0 (25 Nov 2017)
19 * general changes:
20 - removed 2 GB limitation when loading a gig or DLS file
21 - using now native integer size where appropriate
22 - fixed minor issues with man pages (patch by Debian maintainer)
23 - fixed various spelling mistakes (patch by Debian maintainer)
24 - Added new "Serialization" framework (and equally named namespace)
25 which allows to serialize and deserialize native C++ objects
26 in a portable, easy and flexible way.
27 - print compiler warning if no RTTI available
28 - Fixed potential crash in command line tools gig2stereo, korg2gig,
29 korgdump and sf2extract.
30 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
31 (original patch by Paul Brossier, slightly modified).
32 - Debian: Fixed packaging error about invalid substitution variable
33 "Source-Version".
34 - Raised Debian compatibility level to Debian 9 "Stretch".
35
36 * src/gig.cpp, src/gig.h:
37 - fixed bug in Script::SetGroup: the script chunk wasn't moved
38 - fixed compilation error with clang 3.4
39 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
40 as one single monolithic gig file. In case .gig file is >= 2GB expect a
41 large monolithic file, otherwise if .gig file is < 2 GB check for
42 "extension" files (.gx01, .gx02, ...) instead.
43 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
44 if there were dimensions after the velocity dimension: it only created
45 valid velocity tables for cases of dimensions lower than the velocity
46 dimension.
47 - added new method Sample::VerifyWaveData() which allows to check whether
48 a sample had been damaged for some reason
49 - Fix: samples' CRC checksums were damaged on file structure changes.
50 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
51 - Added new method Sample::GetWaveDataCRC32Checksum().
52 - Changed default value of EG2Release (filter release time) to 60s.
53 - Instruments' default pitch bend range is now +-2 semi tones.
54 - Fixed CRC checksums being wrong sometimes.
55 - Fix: method File::AddContentOf() did not clone script groups and scripts
56 of passed original file.
57 - Added support for serializing & deserializing DimensionRegion
58 objects (and crossfade_t and leverage_ctrl_t objects).
59 - Added enum reflection API functions for retrieving enum declaration type
60 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
61 - Exception class now has a variadic constructor which allows to add
62 textual format specifiers like with printf().
63 - On unknown leverage controller exception: show precise unknown leverage
64 controller number found.
65 - Ignore invalid leverage controller types and just show a warning on the
66 console instead of throwing an exception.
67 - Added new struct eg_opt_t and new class member variable
68 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
69 extension to the gig file format, which allows to override the default
70 behavior of the first two EGs' state machines.
71 - Fixed undefined behavior when loading a gig file with invalid
72 velocity curve parameters (fixes CVE-2017-12951).
73 - Fixed undefined behavior when loading a gig file with invalid wave
74 pool index number (fixes CVE-2017-12954).
75
76 * src/DLS.cpp, src/DLS.h:
77 - Sample: wave pool offsets are now 64 bits (to allow support for files
78 larger than 4 GB).
79 - Exception class now has a variadic constructor which allows to add
80 textual format specifiers like with printf().
81
82 * src/RIFF.cpp, src/RIFF.h:
83 - added support for RIFF files larger than 4 GB, by default the required
84 internal RIFF file offset size is automatically detected (that is RIFF
85 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
86 automatically use 64 bit offsets), a particular offset size can be forced
87 with a new option added to the RIFF File constructor though
88 - when saving a modified, grown RIFF file, the temporary file size during
89 Save() operation will no longer be larger than the final grown file size
90 - Exception class now has a variadic constructor which allows to add
91 textual format specifiers like with printf().
92
93 * src/Serialization.cpp, src/Serialization.h:
94 - Archive: Added method isModified().
95 - Archive: Added method setAutoValue().
96 - Archive: Added method setIntValue().
97 - Archive: Added method setRealValue().
98 - Archive: Added method setBoolValue().
99 - Archive: Added method setEnumValue().
100 - Archive: Added method valueAsString().
101 - Archive::rawData(): Automatically re-encode new raw data stream if
102 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
103 - Object: Added method memberByUID().
104 - Object: remove() method is now protected.
105 - Archive: Added method removeMember().
106 - Archive: Added methods name() and setName().
107 - Archive: Added methods comment() and setComment().
108 - Archive: Added methods timeStampCreated(), timeStampModified(),
109 dateTimeCreated() and dateTimeModified().
110 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
111 - DataType: Implemented demangling C++ type names (for methods
112 asLongDescr() and customTypeName(bool demangle=false)).
113 - Archive::setAutoValue(): Handle human readable boolean text
114 representations like "yes", "no", "true", "false" as expected.
115 - Exception class now has a variadic constructor which allows to add
116 textual format specifiers like with printf().
117 - DataType fix: Retain backward compatibility to older versions of native
118 C++ classes/structs.
119
120 * src/Akai.cpp:
121 - Fixed compilation error with recent, more strict compilers.

135 data
136 - added and implemented new parameter "--verify" which allows to check
137 the raw wave form data integrity of all samples
138 - added and implemented new parameter "--rebuild-checksums" which allows
139 to recalculate the CRC32 checksum of all samples' raw wave data and
140 rebuilding the gig file's global checksum table (i.e. in case the
141 file's checksum table was damaged)
142 - print samples' CRC32 checksums
143 - Print the new EG behavior options (eg_opt_t).
144
145 * src/tools/gigextract.cpp:
146 - Fix: if sample name contains a path separator (slash or backslash) then
147 replace them by a minus sign to avoid file system issues.
148
149 * src/tools/gig2stereo.cpp:
150 - Also merge mono sample pairs with non matching loop information if
151 argument --incompatible was given.

267 one allows to move the subchunk from the current list to another list
268 - POSIX: only assume -1 result value as error on open() calls
269 - POSIX: show operating system's error reason if opening a file failed

369 einf contains file statistics)
370 - write support: DLSID is now generated on the file and the
371 instruments
372 - write support: improved the default values for dimension region
373 parameters
374 - more write support fixes: crossfade parameters were not saved,

411 - added support for custom splits points for other dimensions than
412 velocity (gig v3 feature)
413 - added "smart midi" and "round robin keyboard" dimensions
414 - added new method File::DeleteGroupOnly() which only deletes the given
415 group but moves all its members to another group, the other method,
416 that is File::DeleteGroup() now removes not just the group, but also
417 all the samples that belong to that group
418 - fixed crash which occured on interfering File::DeleteSample() and
419 File::GetNextSample() calls (due to iterator invalidation)
420 - fixed group names which were not saved

422 with the group
423 - added Instrument::MoveRegion method
424 - fixed constructor for Region, which did not initialize correctly
425 when used from Instrument::AddRegion
426 - when saving, override the gig::Regions sample reference simply by
427 the region's first dimension region's sample (avoids an exception
428 when trying to save a new instrument)

448
449 * src/gig.cpp, src/gig.h:
450 - added support for more than one set of custom velocity splits
451 inside a region (for example different velocity split levels for
452 pedal up and pedal down)

454 instead of the wave chunk
455 - keyswitching dimension is changed from split type "normal" to
456 "bit"
457 - real support for 24 bit samples - samples are not truncated to
458 16 bits anymore
459 - support for reading of ".art" files. (Merging of .art and .gig
460 files are not implemented yet.)

503 * src/RIFF.cpp, src/RIFF.h:
504 - added write support
505 - Chunk::LoadChunkData() can now be called again to resize the buffer
506 after a Chunk::Resize() and before the File::Save() call to allow
507 placing the new data in the chunk's write buffer and perform the
508 resize and write operations in one rush
509
510 * src/gigdump.cpp:
511 - fixed to show the correct amount of dimension regions instead of 32
512 (patch by James Wylder)

562 - experimental support for Gigasampler v3 format;
563 64 bit file offsets are truncated to 32 bit, 24 bit samples are
564 truncated to 16 bit, up to 8 dimensions are read, additional
565 articulation informations are ignored at the moment
566 (patch by Andreas Persson)
567 - added some file format compatibility checks
568 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
569 never used, because the necessary check was made before

618
619 * packaging changes:
620 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
621 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
622 - fixed man pages automake install rule (which didn't work on Mandrake,
623 SuSE and Fedora)
624 - fixed generation of Doxygen API documentation (now also included in
625 RPM and Debian packages)
626
627 * src/gig.cpp, src/gig.h:
628 - fixed / improved accuracy of all three velocity to volume
629 transformation functions a.k.a. 'nonlinear','linear','special'
630 (patch by Andreas Persson)
631 - denormals are filtered from the velocity to volume tables
632 - bugfix for dimension region switching (wrong handling of the release
633 trigger dimension, no bit range check for dimensions of split type
634 'split_type_bit')
635 - fixed panorama value in DimensionRegion (invalid conversion from
636 signed 7 bit to signed 8 bit)
637 - added class attribute 'Layers' to class 'gig::Region'
638 - symbol prototyping of gig::Region (fixes build failure with qsampler)

650 Gigasampler layers
651
652 Version 0.7.1 (2 Jul 2004)
653
654 * packaging changes:
655 - added libgig.spec and libgig.pc package configurations for generating
656 Redhat packages
657 - header files included on installation.
658 - autotools-generated files removed from CVS repository.
659 - added support for generating Debian packages
660 - version of shared library can be set in configure.in
661
662 Version 0.7.0 (3 May 2004)
663
664 * general changes:
665 - various big endian specific corrections
666 (successfully tested now on PPC)
667 - minor adjustments to avoid compile errors on some systems
668 (using now pow() instead of powl() and --pedantic g++ compiler switch)
669 - libtoolized the library
670 - added man pages for the command line tools
671 (gigextract, gigdump, dlsdump, rifftree)
672
673 * src/gig.cpp, src/gig.h:
674 - fixed bug in decompression algorithm which caused it not to detect
675 the end of a stream
676 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
677 takes the MIDI key velocity value as an argument and returns the
678 appropriate volume factor (0.0 ... 1.0) for the sample to be played
679 back, the velocity curve transformation functions used for this are
680 only an approximation so far
681 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
682 'Sample::LoopSize' which reflected wrong values
683 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
684 measured in sample points instead of byte offset
685 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
686 'Sample::FineTune'
687 - added class attribute 'Sample::LoopSize'
688 - added method GetInstrument(uint index) to class 'File'
689 - added ReadAndLoop() method to class 'Sample' which is an extension to
690 the normal Read() method to honor the sample's looping information
691 while streaming from disk
692 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
693 'eg2_ctrl_t': replaced this huge enumeration by a structure which
694 reflects the MIDI controller number in case of an ordinary control
695 change controller (this saves a huge switch-case block in the
696 application of the library user)
697 - renamed following attributes in class 'DimensionRegion':
698 'AttenuationContol' -> 'AttenuationController',
699 'InvertAttenuationControl' -> 'InvertAttenuationController',
700 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
701 - minor fix in API documentation for method GetVelocityAttenuation() in
702 class 'DimensionRegion'
703
704 * src/RIFF.cpp, src/RIFF.h:
705 - added additional API documentation
706 - minor fix in Chunk::Read() method (only a minor efficiency issue)
707
708 * src/gigdump.cpp:
709 - added printout of samples' looping informations
710
711 Version 0.6.0 (3 Nov 2003)
712
713 * initial release
