File size: 34392 byte(s)
* RIFF.h: Avoid compiler warning when building for 32 bit windows.

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 - GIG FORMAT EXTENSION: Added attribute
15 DimensionRegion::SustainReleaseTrigger which allows to define whether
16 a sustain pedal up event shall cause a release trigger sample to be
17 played (default: don't play release trigger sample by sustain pedal).
18 - GIG FORMAT EXTENSION: Added attribute
19 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
20 regular behaviour of playing release trigger sample on MIDI note-off
21 events.
22
23 * src/DLS.cpp, src/DLS.h:
24 - File: Fixed implicitly allocated RIFF::File object never been freed.
25
26 * src/Serialization.cpp, src/Serialization.h:
27 - Hide pure internal declarations from header file to avoid numerous
28 compiler warnings when building and linking against the public API.
29 - Fixed comparision logic bug
30 - Fixed memory leak in DataType::customTypeName().
31
32 * src/RIFF.cpp, src/RIFF.h:
33 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
34 caused a resource leak
35 - Avoid compiler warning when building for 32 bit windows.
36
37 * src/tools/gigdump.cpp:
38 - Added command line option --instrument-names which causes only
39 instrument names and their index numbers to be printed.
40
41 Version 4.1.0 (25 Nov 2017)
42 * general changes:
43 - removed 2 GB limitation when loading a gig or DLS file
44 - using now native integer size where appropriate
45 - fixed minor issues with man pages (patch by Debian maintainer)
46 - fixed various spelling mistakes (patch by Debian maintainer)
47 - Added new "Serialization" framework (and equally named namespace)
48 which allows to serialize and deserialize native C++ objects
49 in a portable, easy and flexible way.
50 - print compiler warning if no RTTI available
51 - Fixed potential crash in command line tools gig2stereo, korg2gig,
52 korgdump and sf2extract.
53 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
54 (original patch by Paul Brossier, slightly modified).
55 - Debian: Fixed packaging error about invalid substitution variable
56 "Source-Version".
57 - Raised Debian compatibility level to Debian 9 "Stretch".
58
59 * src/gig.cpp, src/gig.h:
60 - fixed bug in Script::SetGroup: the script chunk wasn't moved
61 - fixed compilation error with clang 3.4
62 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
63 as one single monolithic gig file. In case .gig file is >= 2GB expect a
64 large monolithic file, otherwise if .gig file is < 2 GB check for
65 "extension" files (.gx01, .gx02, ...) instead.
66 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
67 if there were dimensions after the velocity dimension: it only created
68 valid velocity tables for cases of dimensions lower than the velocity
69 dimension.
70 - added new method Sample::VerifyWaveData() which allows to check whether
71 a sample had been damaged for some reason
72 - Fix: samples' CRC checksums were damaged on file structure changes.
73 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
74 - Added new method Sample::GetWaveDataCRC32Checksum().
75 - Changed default value of EG2Release (filter release time) to 60s.
76 - Instruments' default pitch bend range is now +-2 semi tones.
77 - Fixed CRC checksums being wrong sometimes.
78 - Fix: method File::AddContentOf() did not clone script groups and scripts
79 of passed original file.
80 - Added support for serializing & deserializing DimensionRegion
81 objects (and crossfade_t and leverage_ctrl_t objects).
82 - Added enum reflection API functions for retrieving enum declaration type
83 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
84 - Exception class now has a variadic constructor which allows to add
85 textual format specifiers like with printf().
86 - On unknown leverage controller exception: show precise unknown leverage
87 controller number found.
88 - Ignore invalid leverage controller types and just show a warning on the
89 console instead of throwing an exception.
90 - Added new struct eg_opt_t and new class member variable
91 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
92 extension to the gig file format, which allows to override the default
93 behavior of the first two EGs' state machines.
94 - Fixed undefined behavior when loading a gig file with invalid
95 velocity curve parameters (fixes CVE-2017-12951).
96 - Fixed undefined behavior when loading a gig file with invalid wave
97 pool index number (fixes CVE-2017-12954).
98
99 * src/DLS.cpp, src/DLS.h:
100 - Sample: wave pool offsets are now 64 bits (to allow support for files
101 larger than 4 GB).
102 - Exception class now has a variadic constructor which allows to add
103 textual format specifiers like with printf().
104
105 * src/RIFF.cpp, src/RIFF.h:
106 - added support for RIFF files larger than 4 GB, by default the required
107 internal RIFF file offset size is automatically detected (that is RIFF
108 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
109 automatically use 64 bit offsets), a particular offset size can be forced
110 with a new option added to the RIFF File constructor though
111 - when saving a modified, grown RIFF file, the temporary file size during
112 Save() operation will no longer be larger than the final grown file size
113 - Exception class now has a variadic constructor which allows to add
114 textual format specifiers like with printf().
115
116 * src/Serialization.cpp, src/Serialization.h:
117 - Archive: Added method isModified().
118 - Archive: Added method setAutoValue().
119 - Archive: Added method setIntValue().
120 - Archive: Added method setRealValue().
121 - Archive: Added method setBoolValue().
122 - Archive: Added method setEnumValue().
123 - Archive: Added method valueAsString().
124 - Archive::rawData(): Automatically re-encode new raw data stream if
125 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
126 - Object: Added method memberByUID().
127 - Object: remove() method is now protected.
128 - Archive: Added method removeMember().
129 - Archive: Added methods name() and setName().
130 - Archive: Added methods comment() and setComment().
131 - Archive: Added methods timeStampCreated(), timeStampModified(),
132 dateTimeCreated() and dateTimeModified().
133 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
134 - DataType: Implemented demangling C++ type names (for methods
135 asLongDescr() and customTypeName(bool demangle=false)).
136 - Archive::setAutoValue(): Handle human readable boolean text
137 representations like "yes", "no", "true", "false" as expected.
138 - Exception class now has a variadic constructor which allows to add
139 textual format specifiers like with printf().
140 - DataType fix: Retain backward compatibility to older versions of native
141 C++ classes/structs.
142

160 the raw wave form data integrity of all samples
161 - added and implemented new parameter "--rebuild-checksums" which allows
162 to recalculate the CRC32 checksum of all samples' raw wave data and
163 rebuilding the gig file's global checksum table (i.e. in case the
164 file's checksum table was damaged)
165 - print samples' CRC32 checksums
166 - Print the new EG behavior options (eg_opt_t).
167
168 * src/tools/gigextract.cpp:
169 - Fix: if sample name contains a path separator (slash or backslash) then
170 replace them by a minus sign to avoid file system issues.
171
172 * src/tools/gig2stereo.cpp:
173 - Also merge mono sample pairs with non matching loop information if
174 argument --incompatible was given.

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

320 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
321
322 * src/RIFF.cpp, src/RIFF.h:
323 - bugfix: saving to the same file after the file size had been

388 definition are now saved
389 - added constants for gig file versions
390 - write support: the 3crc and einf chunks are now created or
391 updated when a file is saved (3crc contains sample checksums,
392 einf contains file statistics)
393 - write support: DLSID is now generated on the file and the
394 instruments
395 - write support: improved the default values for dimension region
396 parameters

399 when dimensions were added or deleted, v3 wave pool offsets were
400 not saved correctly
401 - write support: 24 bit samples can now be written

406 where incorrectly saved due to an operator precedence mistake
407 - DeleteSample now removes all references to the deleted sample
408 - AddDimension now copies all parameters from existing dimension
409 regions and also makes sure that the samplechannel dimension is
410 placed first in the list of dimensions.

434 - added support for custom splits points for other dimensions than
435 velocity (gig v3 feature)
436 - added "smart midi" and "round robin keyboard" dimensions
437 - added new method File::DeleteGroupOnly() which only deletes the given
438 group but moves all its members to another group, the other method,
439 that is File::DeleteGroup() now removes not just the group, but also
440 all the samples that belong to that group
441 - fixed crash which occured on interfering File::DeleteSample() and
442 File::GetNextSample() calls (due to iterator invalidation)
443 - fixed group names which were not saved

445 with the group
446 - added Instrument::MoveRegion method
447 - fixed constructor for Region, which did not initialize correctly
448 when used from Instrument::AddRegion
449 - when saving, override the gig::Regions sample reference simply by
450 the region's first dimension region's sample (avoids an exception
451 when trying to save a new instrument)
452 - fixed AddDimension() method which did not fill out all mandatory
453 dimension definition fields
454
455 * src/DLS.cpp, src/DLS.h:

471
472 * src/gig.cpp, src/gig.h:
473 - added support for more than one set of custom velocity splits
474 inside a region (for example different velocity split levels for

477 instead of the wave chunk
478 - keyswitching dimension is changed from split type "normal" to
479 "bit"

505
506 * general changes:
507 - added write support (that is for creating and modifying RIFF, DLS and
508 gig files)
509 - loading DLS and gig files is now much more permissive, DLS and gig
510 files are now loaded even if mandatory RIFF chunks are missing
511 - fixed some memory management errors, one of them was causing a
512 crash when a multi-file gig was deallocated
513
514 * src/gig.cpp, src/gig.h:
515 - fixed the GetVelocityCutoff function, it wasn't always using the
516 VCFVelocityScale parameter when no cutoff controller was defined
517 - support for the gig v3 feature to have a number of dimension
518 splits not equal to a power of two
519 - added write support (highly experimental)
520
521 * src/DLS.cpp, src/DLS.h:
522 - fixed loading of Articulation Connections (<artl> list chunks were
523 seeked instead of ordinary <artl> data chunks)
524 - added write support (highly experimental)
525
526 * src/RIFF.cpp, src/RIFF.h:
527 - added write support
528 - Chunk::LoadChunkData() can now be called again to resize the buffer
529 after a Chunk::Resize() and before the File::Save() call to allow
530 placing the new data in the chunk's write buffer and perform the
531 resize and write operations in one rush
532
533 * src/gigdump.cpp:
534 - fixed to show the correct amount of dimension regions instead of 32
535 (patch by James Wylder)
536
537 * src/dlsdump.cpp:
538 - show for every region the name of the referenced sample
539 - show file name in quotation marks
540
541 Version 2.0.2 (15 Aug 2005)
542
543 * packaging changes:
544 - require automake (>= 1.5) for 'make -f Makefile.cvs'
545 (mandatory for 'dist-bzip2' automake option)
546
547 * src/gig.cpp, src/gig.h:
548 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
549 the extension files are read automatically when the samples are
550 loaded
551 - fixed the 24 bit decompression, the result should now be exact
552 instead of an approximation
553 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
554 function to DimensionRegion
555
556 * src/DLS.cpp, src/DLS.h:
557 - the upper bits of the pool table indices are read (used as
558 extension file numbers for gig v3)
559
560 * src/RIFF.cpp, src/RIFF.h:
561 - the file name is remembered in the RIFF::File object
562
563 Version 2.0.1 (12 Jun 2005)
564
565 * packaging changes:
566 - include debian/ directory on 'make dist'
567 - create a bzip2 tarball on 'make dist'
568
569 * src/gigextract.cpp:
570 - show also version of libsndfile or build version of libaudiofile when
571 using the -v switch
572 - fixed mutual link dependency to libsndfile / libaudiofile
573
574 * src/gig.cpp, src/gig.h:
575 - added DimensionRegion::GetVelocityRelease function
576
577 Version 2.0.0 (9 May 2005)
578
579 * packaging changes:
580 - fixed conditional linkage of either libsndfile or libaudiofile
581 (if none of the two exist, configure script will abort)
582 - man pages are now auto generated with the correct libgig version
583
584 * src/gig.cpp, src/gig.h:
585 - experimental support for Gigasampler v3 format;
586 64 bit file offsets are truncated to 32 bit, 24 bit samples are
587 truncated to 16 bit, up to 8 dimensions are read, additional
588 articulation informations are ignored at the moment
589 (patch by Andreas Persson)
590 - added some file format compatibility checks
591 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
592 never used, because the necessary check was made before
593 initialization)
594 - fixed crossfade points order (structure for big endian and little
595 endian systems was interchanged)
596 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

615
616 * src/RIFF.cpp, src/RIFF.h:
617 - fixed method List::LoadSubChunks() which did not restore the original
618 position within the body of the given list chunk
619 - added functions libraryName() and libraryVersion()
620

641
642 * packaging changes:
643 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
644 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
645 - fixed man pages automake install rule (which didn't work on Mandrake,
646 SuSE and Fedora)
647 - fixed generation of Doxygen API documentation (now also included in
648 RPM and Debian packages)
649
650 * src/gig.cpp, src/gig.h:
651 - fixed / improved accuracy of all three velocity to volume
652 transformation functions a.k.a. 'nonlinear','linear','special'
653 (patch by Andreas Persson)
654 - denormals are filtered from the velocity to volume tables
655 - bugfix for dimension region switching (wrong handling of the release
656 trigger dimension, no bit range check for dimensions of split type
657 'split_type_bit')
658 - fixed panorama value in DimensionRegion (invalid conversion from
659 signed 7 bit to signed 8 bit)
660 - added class attribute 'Layers' to class 'gig::Region'
661 - symbol prototyping of gig::Region (fixes build failure with qsampler)
662

670 - added printout for crossfade definitions
671 - added printout for panorama value for each DimensionRegion
672 - replaced printout of DLS Region layer by printout of amount of
673 Gigasampler layers
674
675 Version 0.7.1 (2 Jul 2004)
676
677 * packaging changes:
678 - added libgig.spec and libgig.pc package configurations for generating
679 Redhat packages
680 - header files included on installation.
681 - autotools-generated files removed from CVS repository.
682 - added support for generating Debian packages
683 - version of shared library can be set in configure.in
684
685 Version 0.7.0 (3 May 2004)
686
687 * general changes:
688 - various big endian specific corrections
689 (successfully tested now on PPC)
690 - minor adjustments to avoid compile errors on some systems
691 (using now pow() instead of powl() and --pedantic g++ compiler switch)
692 - libtoolized the library
693 - added man pages for the command line tools
694 (gigextract, gigdump, dlsdump, rifftree)
695
696 * src/gig.cpp, src/gig.h:
697 - fixed bug in decompression algorithm which caused it not to detect
698 the end of a stream
699 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
700 takes the MIDI key velocity value as an argument and returns the
701 appropriate volume factor (0.0 ... 1.0) for the sample to be played
702 back, the velocity curve transformation functions used for this are
703 only an approximation so far
704 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
705 'Sample::LoopSize' which reflected wrong values
706 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
707 measured in sample points instead of byte offset
708 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
709 'Sample::FineTune'
710 - added class attribute 'Sample::LoopSize'
711 - added method GetInstrument(uint index) to class 'File'
712 - added ReadAndLoop() method to class 'Sample' which is an extension to
713 the normal Read() method to honor the sample's looping information
714 while streaming from disk
715 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
716 'eg2_ctrl_t': replaced this huge enumeration by a structure which
717 reflects the MIDI controller number in case of an ordinary control
718 change controller (this saves a huge switch-case block in the
719 application of the library user)
720 - renamed following attributes in class 'DimensionRegion':
721 'AttenuationContol' -> 'AttenuationController',
722 'InvertAttenuationControl' -> 'InvertAttenuationController',
723 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
724 - minor fix in API documentation for method GetVelocityAttenuation() in
725 class 'DimensionRegion'
726
727 * src/RIFF.cpp, src/RIFF.h:
728 - added additional API documentation
729 - minor fix in Chunk::Read() method (only a minor efficiency issue)
730
731 * src/gigdump.cpp:
732 - added printout of samples' looping informations
733
734 Version 0.6.0 (3 Nov 2003)
735
736 * initial release
