File size: 31786 byte(s)
* gig.h/.cpp: Added new struct "eg_opt_t" and new class member variable
  "DimensionRegion::EGOptions" as an extension to the gig file format,
  which allows to override the default behavior of EGs' state machines.
* DLS.h: Got rid of C-style typedefs.
* src/tools/gigdump.cpp: Print the new EG behavior options.
* Bumped version (4.0.0.svn27).

1 Version SVN trunk
2 * general changes:
3 - removed 2 GB limitation when loading a gig or DLS file
4 - using now native integer size where appropriate
5 - fixed minor issues with man pages (patch by Debian maintainer)
6 - fixed various spelling mistakes (patch by Debian maintainer)
7 - Added new "Serialization" framework (and equally named namespace)
8 which allows to serialize and deserialize native C++ objects
9 in a portable, easy and flexible way.
10 - print compiler warning if no RTTI available
11 - Fixed potential crash in command line tools gig2stereo, korg2gig,
12 korgdump and sf2extract.
13
14 * src/gig.cpp, src/gig.h:
15 - fixed bug in Script::SetGroup: the script chunk wasn't moved
16 - fixed compilation error with clang 3.4
17 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
18 as one single monolithic gig file. In case .gig file is >= 2GB expect a
19 large monolithic file, otherwise if .gig file is < 2 GB check for
20 "extension" files (.gx01, .gx02, ...) instead.
21 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
22 if there were dimensions after the velocity dimension: it only created
23 valid velocity tables for cases of dimensions lower than the velocity
24 dimension.
25 - added new method Sample::VerifyWaveData() which allows to check whether
26 a sample had been damaged for some reason
27 - Fix: samples' CRC checksums were damaged on file structure changes.
28 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
29 - Added new method Sample::GetWaveDataCRC32Checksum().
30 - Changed default value of EG2Release (filter release time) to 60s.
31 - Instruments' default pitch bend range is now +-2 semi tones.
32 - Fixed CRC checksums being wrong sometimes.
33 - Fix: method File::AddContentOf() did not clone script groups and scripts
34 of passed original file.
35 - Added support for serializing & deserializing DimensionRegion
36 objects (and crossfade_t and leverage_ctrl_t objects).
37 - Added enum reflection API functions for retrieving enum declaration type
38 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
39 - Exception class now has a variadic constructor which allows to add
40 textual format specifiers like with printf().
41 - On unknown leverage controller exception: show precise unknown leverage
42 controller number found.
43 - Ignore invalid leverage controller types and just show a warning on the
44 console instead of throwing an exception.
45 - Added new struct eg_opt_t and new class member variable
46 DimensionRegion::EGOptions as an extension to the gig file format, which
47 allows to override the default behavior of EGs' state machines.
48
49 * src/DLS.cpp, src/DLS.h:
50 - Sample: wave pool offsets are now 64 bits (to allow support for files
51 larger than 4 GB).
52 - Exception class now has a variadic constructor which allows to add
53 textual format specifiers like with printf().
54
55 * src/RIFF.cpp, src/RIFF.h:
56 - added support for RIFF files larger than 4 GB, by default the required
57 internal RIFF file offset size is automatically detected (that is RIFF
58 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
59 automatically use 64 bit offsets), a particular offset size can be forced
60 with a new option added to the RIFF File constructor though
61 - when saving a modified, grown RIFF file, the temporary file size during
62 Save() operation will no longer be larger than the final grown file size
63 - Exception class now has a variadic constructor which allows to add
64 textual format specifiers like with printf().
65
66 * src/Serialization.cpp, src/Serialization.h:
67 - Archive: Added method isModified().
68 - Archive: Added method setAutoValue().
69 - Archive: Added method setIntValue().
70 - Archive: Added method setRealValue().
71 - Archive: Added method setBoolValue().
72 - Archive: Added method setEnumValue().
73 - Archive: Added method valueAsString().
74 - Archive::rawData(): Automatically re-encode new raw data stream if
75 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
76 - Object: Added method memberByUID().
77 - Object: remove() method is now protected.
78 - Archive: Added method removeMember().
79 - Archive: Added methods name() and setName().
80 - Archive: Added methods comment() and setComment().
81 - Archive: Added methods timeStampCreated(), timeStampModified(),
82 dateTimeCreated() and dateTimeModified().
83 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
84 - DataType: Implemented demangling C++ type names (for methods
85 asLongDescr() and customTypeName(bool demangle=false)).
86 - Archive::setAutoValue(): Handle human readable boolean text
87 representations like "yes", "no", "true", "false" as expected.
88 - Exception class now has a variadic constructor which allows to add
89 textual format specifiers like with printf().

104 - added and implemented new parameter "--verify" which allows to check
105 the raw wave form data integrity of all samples
106 - added and implemented new parameter "--rebuild-checksums" which allows
107 to recalculate the CRC32 checksum of all samples' raw wave data and
108 rebuilding the gig file's global checksum table (i.e. in case the
109 file's checksum table was damaged)
110 - print samples' CRC32 checksums
111 - Print the new EG behavior options (eg_opt_t).
112
113 * src/tools/gigextract.cpp:

115 replace them by a minus sign to avoid file system issues.
116
117 * src/tools/gig2stereo.cpp:
118 - Also merge mono sample pairs with non matching loop information if
119 argument --incompatible was given.
120

350 list in v3 files now always has 128 entries, several parameters
351 where incorrectly saved due to an operator precedence mistake
352 - DeleteSample now removes all references to the deleted sample
353 - AddDimension now copies all parameters from existing dimension
354 regions and also makes sure that the samplechannel dimension is

530 - experimental support for Gigasampler v3 format;
531 64 bit file offsets are truncated to 32 bit, 24 bit samples are
532 truncated to 16 bit, up to 8 dimensions are read, additional
533 articulation informations are ignored at the moment
534 (patch by Andreas Persson)
535 - added some file format compatibility checks
536 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
537 never used, because the necessary check was made before
538 initialization)
539 - fixed crossfade points order (structure for big endian and little
540 endian systems was interchanged)
541 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

543 to their region or dimension region (patch by Andreas Persson)
544 - support for compressed mono samples
545 - experimental support for compressed 24 bit samples
546 - fixed decompression on big-endian CPUs

582 - added command line switch -v to show gigextract's revision and the
583 used libgig version
584
585 Version 1.0.0 (26 Nov 2004)
586
587 * packaging changes:
588 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
589 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
590 - fixed man pages automake install rule (which didn't work on Mandrake,
591 SuSE and Fedora)
592 - fixed generation of Doxygen API documentation (now also included in
593 RPM and Debian packages)
594
595 * src/gig.cpp, src/gig.h:
596 - fixed / improved accuracy of all three velocity to volume
597 transformation functions a.k.a. 'nonlinear','linear','special'
598 (patch by Andreas Persson)
599 - denormals are filtered from the velocity to volume tables
600 - bugfix for dimension region switching (wrong handling of the release
601 trigger dimension, no bit range check for dimensions of split type
602 'split_type_bit')
603 - fixed panorama value in DimensionRegion (invalid conversion from
604 signed 7 bit to signed 8 bit)
605 - added class attribute 'Layers' to class 'gig::Region'
606 - symbol prototyping of gig::Region (fixes build failure with qsampler)
607
608 * src/gigextract.cpp:

610 available then libsndfile is preferred)
611
612 * src/gigdump.cpp:
613 - added printout for dimension informations (amount, type, bits, zones)
614 - added printout for velocity response curve parameters
615 - added printout for crossfade definitions
616 - added printout for panorama value for each DimensionRegion
617 - replaced printout of DLS Region layer by printout of amount of
618 Gigasampler layers
619
620 Version 0.7.1 (2 Jul 2004)
621
622 * packaging changes:
623 - added libgig.spec and libgig.pc package configurations for generating
624 Redhat packages
625 - header files included on installation.
626 - autotools-generated files removed from CVS repository.
627 - added support for generating Debian packages
628 - version of shared library can be set in configure.in
629
630 Version 0.7.0 (3 May 2004)
631
632 * general changes:
633 - various big endian specific corrections
634 (successfully tested now on PPC)
635 - minor adjustments to avoid compile errors on some systems
636 (using now pow() instead of powl() and --pedantic g++ compiler switch)
637 - libtoolized the library
638 - added man pages for the command line tools
639 (gigextract, gigdump, dlsdump, rifftree)
640
641 * src/gig.cpp, src/gig.h:
642 - fixed bug in decompression algorithm which caused it not to detect
643 the end of a stream
644 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
645 takes the MIDI key velocity value as an argument and returns the
646 appropriate volume factor (0.0 ... 1.0) for the sample to be played
647 back, the velocity curve transformation functions used for this are
648 only an approximation so far
649 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
650 'Sample::LoopSize' which reflected wrong values
651 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
652 measured in sample points instead of byte offset
653 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
654 'Sample::FineTune'
655 - added class attribute 'Sample::LoopSize'
656 - added method GetInstrument(uint index) to class 'File'
657 - added ReadAndLoop() method to class 'Sample' which is an extension to
658 the normal Read() method to honor the sample's looping information
659 while streaming from disk
660 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
661 'eg2_ctrl_t': replaced this huge enumeration by a structure which
662 reflects the MIDI controller number in case of an ordinary control
663 change controller (this saves a huge switch-case block in the
664 application of the library user)
665 - renamed following attributes in class 'DimensionRegion':
666 'AttenuationContol' -> 'AttenuationController',
667 'InvertAttenuationControl' -> 'InvertAttenuationController',
668 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
669 - minor fix in API documentation for method GetVelocityAttenuation() in
670 class 'DimensionRegion'
671
672 * src/RIFF.cpp, src/RIFF.h:
673 - added additional API documentation
674 - minor fix in Chunk::Read() method (only a minor efficiency issue)
675
676 * src/gigdump.cpp:
677 - added printout of samples' looping informations
678
679 Version 0.6.0 (3 Nov 2003)
680
681 * initial release
