Revision 3173 - (show annotations) (download)
Wed May 10 23:07:28 2017 UTC (6 years, 10 months ago) by schoenebeck
File size: 30550 byte(s)
* Print compiler warning if no RTTI available.
* Serialization::DataType class: Implemented demangling C++ type
  names (for methods asLongDescr() and
  customTypeName(bool demangle=false)).
* gig.h: When there is no RTTI, only hide API functions which
  really require RTTI.
* Bumped version (4.0.0.svn21).

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
12 * src/gig.cpp, src/gig.h:
13 - fixed bug in Script::SetGroup: the script chunk wasn't moved
14 - fixed compilation error with clang 3.4
15 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
16 as one single monolithic gig file. In case .gig file is >= 2GB expect a
17 large monolithic file, otherwise if .gig file is < 2 GB check for
18 "extension" files (.gx01, .gx02, ...) instead.
19 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
20 if there were dimensions after the velocity dimension: it only created
21 valid velocity tables for cases of dimensions lower than the velocity
22 dimension.
23 - added new method Sample::VerifyWaveData() which allows to check whether
24 a sample had been damaged for some reason
25 - Fix: samples' CRC checksums were damaged on file structure changes.
26 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
27 - Added new method Sample::GetWaveDataCRC32Checksum().
28 - Changed default value of EG2Release (filter release time) to 60s.
29 - Instruments' default pitch bend range is now +-2 semi tones.
30 - Fixed CRC checksums being wrong sometimes.
31 - Fix: method File::AddContentOf() did not clone script groups and scripts
32 of passed original file.
33 - Added support for serializing & deserializing DimensionRegion
34 objects (and crossfade_t and leverage_ctrl_t objects).
35 - Added enum reflection API functions for retrieving enum declaration type
36 information at runtime (countEnum(), enumKey(), enumKeys(), enumValue()).
37
38 * src/DLS.cpp, src/DLS.h:
39 - Sample: wave pool offsets are now 64 bits (to allow support for files
40 larger than 4 GB).
41
42 * src/RIFF.cpp, src/RIFF.h:
43 - added support for RIFF files larger than 4 GB, by default the required
44 internal RIFF file offset size is automatically detected (that is RIFF
45 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
46 automatically use 64 bit offsets), a particular offset size can be forced
47 with a new option added to the RIFF File constructor though
48 - when saving a modified, grown RIFF file, the temporary file size during
49 Save() operation will no longer be larger than the final grown file size
50
51 * src/Serialization.cpp, src/Serialization.h:
52 - Archive: Added method isModified().
53 - Archive: Added method setAutoValue().
54 - Archive: Added method setIntValue().
55 - Archive: Added method setRealValue().
56 - Archive: Added method setBoolValue().
57 - Archive: Added method setEnumValue().
58 - Archive: Added method valueAsString().
59 - Archive::rawData(): Automatically re-encode new raw data stream if
60 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
61 - Object: Added method memberByUID().
62 - Object: remove() method is now protected.
63 - Archive: Added method removeMember().
64 - Archive: Added methods name() and setName().
65 - Archive: Added methods comment() and setComment().
66 - Archive: Added methods timeStampCreated(), timeStampModified(),
67 dateTimeCreated() and dateTimeModified().
68 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
69 - DataType: Implemented demangling C++ type names (for methods
70 asLongDescr() and customTypeName(bool demangle=false)).
71
72 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
73 - improved output of non-ascii characters in usage messages

75
76 * src/tools/korg2gig.cpp:
77 - fixed c++11 narrowing warnings

81 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
82 dimension regions
83 - additionally print RIFF chunk file offset and RIFF chunk size of sample
84 data
85 - added and implemented new parameter "--verify" which allows to check
86 the raw wave form data integrity of all samples
87 - added and implemented new parameter "--rebuild-checksums" which allows
88 to recalculate the CRC32 checksum of all samples' raw wave data and
89 rebuilding the gig file's global checksum table (i.e. in case the
90 file's checksum table was damaged)
91 - print samples' CRC32 checksums
92
93 * src/tools/gigextract.cpp:
94 - Fix: if sample name contains a path separator (slash or backslash) then
95 replace them by a minus sign to avoid file system issues.
96
97 * src/tools/gig2stereo.cpp:
98 - Also merge mono sample pairs with non matching loop information if
99 argument --incompatible was given.
100
101 * packaging changes:

138
139 * AKAI file format:
140 - Added Linux/POSIX ported version of libakai. Note that libakai is released
141 under LGPL terms while libgig is released under GPL terms. To handle this
142 license difference appropriately the AKAI support part is built as

245 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
246
247 * src/RIFF.cpp, src/RIFF.h:
248 - bugfix: saving to the same file after the file size had been

318 - write support: DLSID is now generated on the file and the
319 instruments
320 - write support: improved the default values for dimension region
321 parameters

360 velocity (gig v3 feature)
361 - added "smart midi" and "round robin keyboard" dimensions
362 - added new method File::DeleteGroupOnly() which only deletes the given
363 group but moves all its members to another group, the other method,

372 - fixed constructor for Region, which did not initialize correctly
373 when used from Instrument::AddRegion
374 - when saving, override the gig::Regions sample reference simply by
375 the region's first dimension region's sample (avoids an exception
376 when trying to save a new instrument)

378 dimension definition fields
379
380 * src/DLS.cpp, src/DLS.h:

509 * src/gig.cpp, src/gig.h:
510 - experimental support for Gigasampler v3 format;
511 64 bit file offsets are truncated to 32 bit, 24 bit samples are
512 truncated to 16 bit, up to 8 dimensions are read, additional
513 articulation informations are ignored at the moment
514 (patch by Andreas Persson)
515 - added some file format compatibility checks
516 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
517 never used, because the necessary check was made before
518 initialization)
519 - fixed crossfade points order (structure for big endian and little
520 endian systems was interchanged)
521 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

523 to their region or dimension region (patch by Andreas Persson)
524 - support for compressed mono samples
525 - experimental support for compressed 24 bit samples
526 - fixed decompression on big-endian CPUs
527 - fixed decompression bug that truncated the last block of samples

561 - support for compressed mono samples and compressed 24 bit samples
562 - added command line switch -v to show gigextract's revision and the
563 used libgig version
564
565 Version 1.0.0 (26 Nov 2004)
566
567 * packaging changes:
568 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
569 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
570 - fixed man pages automake install rule (which didn't work on Mandrake,
571 SuSE and Fedora)
572 - fixed generation of Doxygen API documentation (now also included in
573 RPM and Debian packages)
574
575 * src/gig.cpp, src/gig.h:
576 - fixed / improved accuracy of all three velocity to volume
577 transformation functions a.k.a. 'nonlinear','linear','special'
578 (patch by Andreas Persson)
579 - denormals are filtered from the velocity to volume tables
580 - bugfix for dimension region switching (wrong handling of the release
581 trigger dimension, no bit range check for dimensions of split type
582 'split_type_bit')
583 - fixed panorama value in DimensionRegion (invalid conversion from
584 signed 7 bit to signed 8 bit)
585 - added class attribute 'Layers' to class 'gig::Region'
586 - symbol prototyping of gig::Region (fixes build failure with qsampler)
587
588 * src/gigextract.cpp:
589 - added support for libsndfile (if libaudiofile and libsndfile are
590 available then libsndfile is preferred)
591
592 * src/gigdump.cpp:
593 - added printout for dimension informations (amount, type, bits, zones)
594 - added printout for velocity response curve parameters
595 - added printout for crossfade definitions
596 - added printout for panorama value for each DimensionRegion
597 - replaced printout of DLS Region layer by printout of amount of
598 Gigasampler layers
599
600 Version 0.7.1 (2 Jul 2004)
601
602 * packaging changes:
603 - added libgig.spec and libgig.pc package configurations for generating
604 Redhat packages
605 - header files included on installation.
606 - autotools-generated files removed from CVS repository.
607 - added support for generating Debian packages
608 - version of shared library can be set in configure.in
609
610 Version 0.7.0 (3 May 2004)
611
612 * general changes:
613 - various big endian specific corrections
614 (successfully tested now on PPC)
615 - minor adjustments to avoid compile errors on some systems
616 (using now pow() instead of powl() and --pedantic g++ compiler switch)
617 - libtoolized the library
618 - added man pages for the command line tools
619 (gigextract, gigdump, dlsdump, rifftree)
620
621 * src/gig.cpp, src/gig.h:
622 - fixed bug in decompression algorithm which caused it not to detect
623 the end of a stream
624 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
625 takes the MIDI key velocity value as an argument and returns the
626 appropriate volume factor (0.0 ... 1.0) for the sample to be played
627 back, the velocity curve transformation functions used for this are
628 only an approximation so far
629 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
630 'Sample::LoopSize' which reflected wrong values
631 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
632 measured in sample points instead of byte offset
633 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
634 'Sample::FineTune'
635 - added class attribute 'Sample::LoopSize'
636 - added method GetInstrument(uint index) to class 'File'
637 - added ReadAndLoop() method to class 'Sample' which is an extension to
638 the normal Read() method to honor the sample's looping information
639 while streaming from disk
640 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
641 'eg2_ctrl_t': replaced this huge enumeration by a structure which
642 reflects the MIDI controller number in case of an ordinary control
643 change controller (this saves a huge switch-case block in the
644 application of the library user)
645 - renamed following attributes in class 'DimensionRegion':
646 'AttenuationContol' -> 'AttenuationController',
647 'InvertAttenuationControl' -> 'InvertAttenuationController',
648 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
649 - minor fix in API documentation for method GetVelocityAttenuation() in
650 class 'DimensionRegion'
651
652 * src/RIFF.cpp, src/RIFF.h:
653 - added additional API documentation
654 - minor fix in Chunk::Read() method (only a minor efficiency issue)
655
656 * src/gigdump.cpp:
657 - added printout of samples' looping informations
658
659 Version 0.6.0 (3 Nov 2003)
660
661 * initial release
