File size: 33664 byte(s)
* Fixed gig v4 files falsely being handled as v2 format
  (patch by Ivan Maguidhir).
* Added gig v4 version identifier (File::VERSION_4).
* Bumped version (4.1.0.svn6).

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 - Added new method File::CountSamples().
10 - Added new method File::CountInstruments().
11 - Fixed gig v4 files falsely being handled as v2 format
12 (patch by Ivan Maguidhir).
13 - Added gig v4 version identifier (File::VERSION_4).
14
15 * src/Serialization.cpp, src/Serialization.h:
16 - Hide pure internal declarations from header file to avoid numerous
17 compiler warnings when building and linking against the public API.
18
19 * src/RIFF.cpp, src/RIFF.h:
20 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
21 caused a resource leak
22
23 * src/tools/gigdump.cpp:
24 - Added command line option --instrument-names which causes only
25 instrument names and their index numbers to be printed.
26
27 Version 4.1.0 (25 Nov 2017)
28 * general changes:
29 - removed 2 GB limitation when loading a gig or DLS file
30 - using now native integer size where appropriate
31 - fixed minor issues with man pages (patch by Debian maintainer)
32 - fixed various spelling mistakes (patch by Debian maintainer)
33 - Added new "Serialization" framework (and equally named namespace)
34 which allows to serialize and deserialize native C++ objects
35 in a portable, easy and flexible way.
36 - print compiler warning if no RTTI available
37 - Fixed potential crash in command line tools gig2stereo, korg2gig,
38 korgdump and sf2extract.
39 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
40 (original patch by Paul Brossier, slightly modified).
41 - Debian: Fixed packaging error about invalid substitution variable
42 "Source-Version".
43 - Raised Debian compatibility level to Debian 9 "Stretch".
44
45 * src/gig.cpp, src/gig.h:
46 - fixed bug in Script::SetGroup: the script chunk wasn't moved
47 - fixed compilation error with clang 3.4
48 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
49 as one single monolithic gig file. In case .gig file is >= 2GB expect a
50 large monolithic file, otherwise if .gig file is < 2 GB check for
51 "extension" files (.gx01, .gx02, ...) instead.
52 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
53 if there were dimensions after the velocity dimension: it only created
54 valid velocity tables for cases of dimensions lower than the velocity
55 dimension.
56 - added new method Sample::VerifyWaveData() which allows to check whether
57 a sample had been damaged for some reason
58 - Fix: samples' CRC checksums were damaged on file structure changes.
59 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
60 - Added new method Sample::GetWaveDataCRC32Checksum().
61 - Changed default value of EG2Release (filter release time) to 60s.
62 - Instruments' default pitch bend range is now +-2 semi tones.
63 - Fixed CRC checksums being wrong sometimes.
64 - Fix: method File::AddContentOf() did not clone script groups and scripts
65 of passed original file.
66 - Added support for serializing & deserializing DimensionRegion
67 objects (and crossfade_t and leverage_ctrl_t objects).
68 - Added enum reflection API functions for retrieving enum declaration type
69 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
70 - Exception class now has a variadic constructor which allows to add
71 textual format specifiers like with printf().
72 - On unknown leverage controller exception: show precise unknown leverage
73 controller number found.
74 - Ignore invalid leverage controller types and just show a warning on the
75 console instead of throwing an exception.
76 - Added new struct eg_opt_t and new class member variable
77 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
78 extension to the gig file format, which allows to override the default
79 behavior of the first two EGs' state machines.
80 - Fixed undefined behavior when loading a gig file with invalid
81 velocity curve parameters (fixes CVE-2017-12951).
82 - Fixed undefined behavior when loading a gig file with invalid wave
83 pool index number (fixes CVE-2017-12954).
84
85 * src/DLS.cpp, src/DLS.h:
86 - Sample: wave pool offsets are now 64 bits (to allow support for files
87 larger than 4 GB).
88 - Exception class now has a variadic constructor which allows to add
89 textual format specifiers like with printf().
90
91 * src/RIFF.cpp, src/RIFF.h:
92 - added support for RIFF files larger than 4 GB, by default the required
93 internal RIFF file offset size is automatically detected (that is RIFF
94 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
95 automatically use 64 bit offsets), a particular offset size can be forced
96 with a new option added to the RIFF File constructor though
97 - when saving a modified, grown RIFF file, the temporary file size during
98 Save() operation will no longer be larger than the final grown file size
99 - Exception class now has a variadic constructor which allows to add
100 textual format specifiers like with printf().
101
102 * src/Serialization.cpp, src/Serialization.h:
103 - Archive: Added method isModified().
104 - Archive: Added method setAutoValue().
105 - Archive: Added method setIntValue().
106 - Archive: Added method setRealValue().
107 - Archive: Added method setBoolValue().
108 - Archive: Added method setEnumValue().
109 - Archive: Added method valueAsString().
110 - Archive::rawData(): Automatically re-encode new raw data stream if
111 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
112 - Object: Added method memberByUID().
113 - Object: remove() method is now protected.
114 - Archive: Added method removeMember().
115 - Archive: Added methods name() and setName().
116 - Archive: Added methods comment() and setComment().
117 - Archive: Added methods timeStampCreated(), timeStampModified(),
118 dateTimeCreated() and dateTimeModified().
119 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
120 - DataType: Implemented demangling C++ type names (for methods
121 asLongDescr() and customTypeName(bool demangle=false)).
122 - Archive::setAutoValue(): Handle human readable boolean text
123 representations like "yes", "no", "true", "false" as expected.
124 - Exception class now has a variadic constructor which allows to add
125 textual format specifiers like with printf().
126 - DataType fix: Retain backward compatibility to older versions of native
127 C++ classes/structs.
128

148 to recalculate the CRC32 checksum of all samples' raw wave data and
149 rebuilding the gig file's global checksum table (i.e. in case the
150 file's checksum table was damaged)
151 - print samples' CRC32 checksums
152 - Print the new EG behavior options (eg_opt_t).
153
154 * src/tools/gigextract.cpp:
155 - Fix: if sample name contains a path separator (slash or backslash) then
156 replace them by a minus sign to avoid file system issues.
157
158 * src/tools/gig2stereo.cpp:
159 - Also merge mono sample pairs with non matching loop information if
160 argument --incompatible was given.

241 new one being dropped after save operation and the gig file being tainted
242 (chunks at wrong location in the RIFF tree).
243 - Added new method Instrument::MoveTo() which allows to rearrange the order
244 of instruments within the same gig file.
245

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

306 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
307
308 * src/RIFF.cpp, src/RIFF.h:
309 - bugfix: saving to the same file after the file size had been

374 definition are now saved
375 - added constants for gig file versions
376 - write support: the 3crc and einf chunks are now created or
377 updated when a file is saved (3crc contains sample checksums,
378 einf contains file statistics)
379 - write support: DLSID is now generated on the file and the
380 instruments
381 - write support: improved the default values for dimension region
382 parameters
383 - more write support fixes: crossfade parameters were not saved,
384 v3 dimension limits were not correctly initialized and saved
385 when dimensions were added or deleted, v3 wave pool offsets were
386 not saved correctly
387 - write support: 24 bit samples can now be written

391 list in v3 files now always has 128 entries, several parameters
392 where incorrectly saved due to an operator precedence mistake
393 - DeleteSample now removes all references to the deleted sample
394 - AddDimension now copies all parameters from existing dimension
395 regions and also makes sure that the samplechannel dimension is
396 placed first in the list of dimensions.

398 parent Region
399 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

420 - added support for custom splits points for other dimensions than
421 velocity (gig v3 feature)
422 - added "smart midi" and "round robin keyboard" dimensions
423 - added new method File::DeleteGroupOnly() which only deletes the given
424 group but moves all its members to another group, the other method,
425 that is File::DeleteGroup() now removes not just the group, but also
426 all the samples that belong to that group
427 - fixed crash which occured on interfering File::DeleteSample() and
428 File::GetNextSample() calls (due to iterator invalidation)
429 - fixed group names which were not saved

431 with the group
432 - added Instrument::MoveRegion method
433 - fixed constructor for Region, which did not initialize correctly
434 when used from Instrument::AddRegion
435 - when saving, override the gig::Regions sample reference simply by
436 the region's first dimension region's sample (avoids an exception
437 when trying to save a new instrument)
438 - fixed AddDimension() method which did not fill out all mandatory
439 dimension definition fields
440
441 * src/DLS.cpp, src/DLS.h:

463 instead of the wave chunk
464 - keyswitching dimension is changed from split type "normal" to
465 "bit"
466 - real support for 24 bit samples - samples are not truncated to
467 16 bits anymore

492 * general changes:
493 - added write support (that is for creating and modifying RIFF, DLS and
494 gig files)
495 - loading DLS and gig files is now much more permissive, DLS and gig
496 files are now loaded even if mandatory RIFF chunks are missing
497 - fixed some memory management errors, one of them was causing a
498 crash when a multi-file gig was deallocated
499
500 * src/gig.cpp, src/gig.h:
501 - fixed the GetVelocityCutoff function, it wasn't always using the
502 VCFVelocityScale parameter when no cutoff controller was defined
503 - support for the gig v3 feature to have a number of dimension
504 splits not equal to a power of two
505 - added write support (highly experimental)
506
507 * src/DLS.cpp, src/DLS.h:

509 seeked instead of ordinary <artl> data chunks)
510 - added write support (highly experimental)
511
512 * src/RIFF.cpp, src/RIFF.h:
513 - added write support
514 - Chunk::LoadChunkData() can now be called again to resize the buffer
515 after a Chunk::Resize() and before the File::Save() call to allow
516 placing the new data in the chunk's write buffer and perform the
517 resize and write operations in one rush
518
519 * src/gigdump.cpp:
520 - fixed to show the correct amount of dimension regions instead of 32
521 (patch by James Wylder)
522

570 * src/gig.cpp, src/gig.h:
571 - experimental support for Gigasampler v3 format;
572 64 bit file offsets are truncated to 32 bit, 24 bit samples are
573 truncated to 16 bit, up to 8 dimensions are read, additional
574 articulation informations are ignored at the moment
575 (patch by Andreas Persson)
576 - added some file format compatibility checks
577 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
578 never used, because the necessary check was made before

580 - fixed crossfade points order (structure for big endian and little
581 endian systems was interchanged)
582 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

627
628 * packaging changes:
629 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
630 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
631 - fixed man pages automake install rule (which didn't work on Mandrake,
632 SuSE and Fedora)
633 - fixed generation of Doxygen API documentation (now also included in
634 RPM and Debian packages)
635
636 * src/gig.cpp, src/gig.h:
637 - fixed / improved accuracy of all three velocity to volume
638 transformation functions a.k.a. 'nonlinear','linear','special'
639 (patch by Andreas Persson)
640 - denormals are filtered from the velocity to volume tables
641 - bugfix for dimension region switching (wrong handling of the release
642 trigger dimension, no bit range check for dimensions of split type
643 'split_type_bit')
644 - fixed panorama value in DimensionRegion (invalid conversion from
645 signed 7 bit to signed 8 bit)
646 - added class attribute 'Layers' to class 'gig::Region'
647 - symbol prototyping of gig::Region (fixes build failure with qsampler)
648

659 Gigasampler layers
660
661 Version 0.7.1 (2 Jul 2004)
662
663 * packaging changes:
664 - added libgig.spec and libgig.pc package configurations for generating
665 Redhat packages
666 - header files included on installation.
667 - autotools-generated files removed from CVS repository.
668 - added support for generating Debian packages
669 - version of shared library can be set in configure.in
670
671 Version 0.7.0 (3 May 2004)
672
673 * general changes:
674 - various big endian specific corrections
675 (successfully tested now on PPC)
676 - minor adjustments to avoid compile errors on some systems
677 (using now pow() instead of powl() and --pedantic g++ compiler switch)
678 - libtoolized the library
679 - added man pages for the command line tools
680 (gigextract, gigdump, dlsdump, rifftree)
681
682 * src/gig.cpp, src/gig.h:
683 - fixed bug in decompression algorithm which caused it not to detect
684 the end of a stream
685 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
686 takes the MIDI key velocity value as an argument and returns the
687 appropriate volume factor (0.0 ... 1.0) for the sample to be played
688 back, the velocity curve transformation functions used for this are
689 only an approximation so far
690 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
691 'Sample::LoopSize' which reflected wrong values
692 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
693 measured in sample points instead of byte offset
694 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
695 'Sample::FineTune'
696 - added class attribute 'Sample::LoopSize'
697 - added method GetInstrument(uint index) to class 'File'
698 - added ReadAndLoop() method to class 'Sample' which is an extension to
699 the normal Read() method to honor the sample's looping information
700 while streaming from disk
701 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
702 'eg2_ctrl_t': replaced this huge enumeration by a structure which
703 reflects the MIDI controller number in case of an ordinary control
704 change controller (this saves a huge switch-case block in the
705 application of the library user)
706 - renamed following attributes in class 'DimensionRegion':
707 'AttenuationContol' -> 'AttenuationController',
708 'InvertAttenuationControl' -> 'InvertAttenuationController',
709 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
710 - minor fix in API documentation for method GetVelocityAttenuation() in
711 class 'DimensionRegion'
712
713 * src/RIFF.cpp, src/RIFF.h:
714 - added additional API documentation
715 - minor fix in Chunk::Read() method (only a minor efficiency issue)
716
717 * src/gigdump.cpp:
718 - added printout of samples' looping informations
719
720 Version 0.6.0 (3 Nov 2003)
721
722 * initial release
