1 persson 2836 Version SVN trunk
2 schoenebeck 2909 * general changes:
3 schoenebeck 2912 - removed 2 GB limitation when loading a gig or DLS file
4 schoenebeck 2922 - using now native integer size where appropriate
5 schoenebeck 3047 - fixed minor issues with man pages (patch by Debian maintainer)
6 schoenebeck 3048 - fixed various spelling mistakes (patch by Debian maintainer)
7 schoenebeck 3138 - 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 schoenebeck 3173 - print compiler warning if no RTTI available
11 schoenebeck 3175 - Fixed potential crash in command line tools gig2stereo, korg2gig,
12     korgdump and sf2extract.
13 schoenebeck 2909
14 schoenebeck 2912 * src/gig.cpp, src/gig.h:
15 persson 2836 - fixed bug in Script::SetGroup: the script chunk wasn't moved
16     - fixed compilation error with clang 3.4
17 schoenebeck 2912 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
18 schoenebeck 2913 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 schoenebeck 2923 - 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 schoenebeck 2985 - 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 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
29     - Added new method Sample::GetWaveDataCRC32Checksum().
30 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
31 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
32 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.
33 schoenebeck 3117 - Fix: method File::AddContentOf() did not clone script groups and scripts
34     of passed original file.
35 schoenebeck 3138 - Added support for serializing & deserializing DimensionRegion
36     objects (and crossfade_t and leverage_ctrl_t objects).
37 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
38 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
39 schoenebeck 3198 - 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 schoenebeck 2909
44 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
45     - Sample: wave pool offsets are now 64 bits (to allow support for files
46     larger than 4 GB).
47 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
48     textual format specifiers like with printf().
49 schoenebeck 2912
50     * src/RIFF.cpp, src/RIFF.h:
51     - added support for RIFF files larger than 4 GB, by default the required
52     internal RIFF file offset size is automatically detected (that is RIFF
53     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
54     automatically use 64 bit offsets), a particular offset size can be forced
55     with a new option added to the RIFF File constructor though
56     - when saving a modified, grown RIFF file, the temporary file size during
57     Save() operation will no longer be larger than the final grown file size
58 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
59     textual format specifiers like with printf().
60 schoenebeck 2912

78 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
79 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
80     asLongDescr() and customTypeName(bool demangle=false)).
81 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
82     representations like "yes", "no", "true", "false" as expected.
83 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
84     textual format specifiers like with printf().

101     - added and implemented new parameter "--rebuild-checksums" which allows
102     to recalculate the CRC32 checksum of all samples' raw wave data and
103     rebuilding the gig file's global checksum table (i.e. in case the
104     file's checksum table was damaged)

624 schoenebeck 58 Version 0.7.0 (3 May 2004)
625    
626     * general changes:
627     - various big endian specific corrections
628     (successfully tested now on PPC)
629     - minor adjustments to avoid compile errors on some systems
630     (using now pow() instead of powl() and --pedantic g++ compiler switch)
631     - libtoolized the library
632     - added man pages for the command line tools
633     (gigextract, gigdump, dlsdump, rifftree)
634    
635     * src/gig.cpp, src/gig.h:
636     - fixed bug in decompression algorithm which caused it not to detect
637     the end of a stream
638     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
639     takes the MIDI key velocity value as an argument and returns the
640     appropriate volume factor (0.0 ... 1.0) for the sample to be played
641     back, the velocity curve transformation functions used for this are
642     only an approximation so far
643     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
644     'Sample::LoopSize' which reflected wrong values
645     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
646     measured in sample points instead of byte offset
647     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
648     'Sample::FineTune'
649     - added class attribute 'Sample::LoopSize'
650     - added method GetInstrument(uint index) to class 'File'
651     - added ReadAndLoop() method to class 'Sample' which is an extension to
652     the normal Read() method to honor the sample's looping information
653     while streaming from disk
654     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
655     'eg2_ctrl_t': replaced this huge enumeration by a structure which
656     reflects the MIDI controller number in case of an ordinary control
657     change controller (this saves a huge switch-case block in the
658     application of the library user)
659     - renamed following attributes in class 'DimensionRegion':
660     'AttenuationContol' -> 'AttenuationController',
661     'InvertAttenuationControl' -> 'InvertAttenuationController',
662     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
663     - minor fix in API documentation for method GetVelocityAttenuation() in
664     class 'DimensionRegion'
665    
666     * src/RIFF.cpp, src/RIFF.h:
667     - added additional API documentation
668     - minor fix in Chunk::Read() method (only a minor efficiency issue)
669    
670     * src/gigdump.cpp:
671     - added printout of samples' looping informations
672    
673 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
