Sun May 14 17:08:42 2017 UTC (19 months ago) by schoenebeck
File size: 30653 byte(s)
* Just some minor API cosmetics: renamed recently added
  enum reflections API function countEmum() -> enumCount().
* Bumped version (4.0.0.svn22).

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
40 * src/DLS.cpp, src/DLS.h:
41 - Sample: wave pool offsets are now 64 bits (to allow support for files
42 larger than 4 GB).
43
44 * src/RIFF.cpp, src/RIFF.h:
45 - added support for RIFF files larger than 4 GB, by default the required
46 internal RIFF file offset size is automatically detected (that is RIFF
47 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
48 automatically use 64 bit offsets), a particular offset size can be forced
49 with a new option added to the RIFF File constructor though
50 - when saving a modified, grown RIFF file, the temporary file size during
51 Save() operation will no longer be larger than the final grown file size
52
53 * src/Serialization.cpp, src/Serialization.h:
54 - Archive: Added method isModified().
55 - Archive: Added method setAutoValue().
56 - Archive: Added method setIntValue().
57 - Archive: Added method setRealValue().
58 - Archive: Added method setBoolValue().
59 - Archive: Added method setEnumValue().
60 - Archive: Added method valueAsString().
61 - Archive::rawData(): Automatically re-encode new raw data stream if
62 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
63 - Object: Added method memberByUID().
64 - Object: remove() method is now protected.
65 - Archive: Added method removeMember().
66 - Archive: Added methods name() and setName().
67 - Archive: Added methods comment() and setComment().
68 - Archive: Added methods timeStampCreated(), timeStampModified(),
69 dateTimeCreated() and dateTimeModified().
70 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
71 - DataType: Implemented demangling C++ type names (for methods
72 asLongDescr() and customTypeName(bool demangle=false)).
73
74 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
75 - improved output of non-ascii characters in usage messages
76 - fixed printf format strings
77
78 * src/tools/korg2gig.cpp:
79 - fixed c++11 narrowing warnings

82 * src/tools/gigdump.cpp:
83 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
84 dimension regions
85 - additionally print RIFF chunk file offset and RIFF chunk size of sample
86 data
87 - added and implemented new parameter "--verify" which allows to check
88 the raw wave form data integrity of all samples
89 - added and implemented new parameter "--rebuild-checksums" which allows
90 to recalculate the CRC32 checksum of all samples' raw wave data and
91 rebuilding the gig file's global checksum table (i.e. in case the
92 file's checksum table was damaged)
93 - print samples' CRC32 checksums
94
95 * src/tools/gigextract.cpp:
96 - Fix: if sample name contains a path separator (slash or backslash) then
97 replace them by a minus sign to avoid file system issues.
98
99 * src/tools/gig2stereo.cpp:
100 - Also merge mono sample pairs with non matching loop information if
101 argument --incompatible was given.
102

140
141 * AKAI file format:
142 - Added Linux/POSIX ported version of libakai. Note that libakai is released
143 under LGPL terms while libgig is released under GPL terms. To handle this
144 license difference appropriately the AKAI support part is built as
145 separate DLL (.so file).
146 - Fixed Mac OSX support so that the Akai lib files and tools compile without
147 any exotic third party libraries.

247 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
248
249 * src/RIFF.cpp, src/RIFF.h:

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

380 dimension definition fields
381
382 * src/DLS.cpp, src/DLS.h:

512 - experimental support for Gigasampler v3 format;
513 64 bit file offsets are truncated to 32 bit, 24 bit samples are
514 truncated to 16 bit, up to 8 dimensions are read, additional
515 articulation informations are ignored at the moment
516 (patch by Andreas Persson)
517 - added some file format compatibility checks
518 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
519 never used, because the necessary check was made before
520 initialization)
521 - fixed crossfade points order (structure for big endian and little
522 endian systems was interchanged)
523 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
524 - fixed crash which occured when patches did not have a sample assigned
525 to their region or dimension region (patch by Andreas Persson)
526 - support for compressed mono samples
527 - experimental support for compressed 24 bit samples
528 - fixed decompression on big-endian CPUs
529 - fixed decompression bug that truncated the last block of samples
530 - external decompression buffers can now be used for streaming samples
531 to avoid race conditions in case of multiple streaming threads
532 - added pre-calculated sample attenuation parameter
533 - added v3 "random" and "round robin" dimensions
534 - implemented progress indicator callback mechanism for loading
535 instruments and samples

540 to be zero
541 - added functions libraryName() and libraryVersion()
542
543 * src/RIFF.cpp, src/RIFF.h:

545 position within the body of the given list chunk
546 - added functions libraryName() and libraryVersion()
547
548 * src/rifftree.cpp:

550 libgig version
551
552 * src/dlsdump.cpp:
553 - added command line switch -v to show dlsdump's revision and the used
554 libgig version
555
556 * src/gigdump.cpp:

558 LoopPlayCount
559 - added command line switch -v to show gigdump's revision and the used
560 libgig version
561
562 * src/gigextract.cpp:
563 - support for compressed mono samples and compressed 24 bit samples
564 - added command line switch -v to show gigextract's revision and the
565 used libgig version
566
567 Version 1.0.0 (26 Nov 2004)
568
569 * packaging changes:
570 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
571 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
572 - fixed man pages automake install rule (which didn't work on Mandrake,
573 SuSE and Fedora)
574 - fixed generation of Doxygen API documentation (now also included in
575 RPM and Debian packages)
576
577 * src/gig.cpp, src/gig.h:
578 - fixed / improved accuracy of all three velocity to volume
579 transformation functions a.k.a. 'nonlinear','linear','special'
580 (patch by Andreas Persson)
581 - denormals are filtered from the velocity to volume tables
582 - bugfix for dimension region switching (wrong handling of the release
583 trigger dimension, no bit range check for dimensions of split type
584 'split_type_bit')
585 - fixed panorama value in DimensionRegion (invalid conversion from
586 signed 7 bit to signed 8 bit)
587 - added class attribute 'Layers' to class 'gig::Region'
588 - symbol prototyping of gig::Region (fixes build failure with qsampler)
589
590 * src/gigextract.cpp:
591 - added support for libsndfile (if libaudiofile and libsndfile are
592 available then libsndfile is preferred)
593
594 * src/gigdump.cpp:
595 - added printout for dimension informations (amount, type, bits, zones)
596 - added printout for velocity response curve parameters
597 - added printout for crossfade definitions
598 - added printout for panorama value for each DimensionRegion
599 - replaced printout of DLS Region layer by printout of amount of
600 Gigasampler layers
601
602 Version 0.7.1 (2 Jul 2004)
603
604 * packaging changes:
605 - added libgig.spec and libgig.pc package configurations for generating
606 Redhat packages
607 - header files included on installation.
608 - autotools-generated files removed from CVS repository.
609 - added support for generating Debian packages
610 - version of shared library can be set in configure.in
611
612 Version 0.7.0 (3 May 2004)
613
614 * general changes:
615 - various big endian specific corrections
616 (successfully tested now on PPC)
617 - minor adjustments to avoid compile errors on some systems
618 (using now pow() instead of powl() and --pedantic g++ compiler switch)
619 - libtoolized the library
620 - added man pages for the command line tools
621 (gigextract, gigdump, dlsdump, rifftree)
622
623 * src/gig.cpp, src/gig.h:
624 - fixed bug in decompression algorithm which caused it not to detect
625 the end of a stream
626 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
627 takes the MIDI key velocity value as an argument and returns the
628 appropriate volume factor (0.0 ... 1.0) for the sample to be played
629 back, the velocity curve transformation functions used for this are
630 only an approximation so far
631 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
632 'Sample::LoopSize' which reflected wrong values
633 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
634 measured in sample points instead of byte offset
635 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
636 'Sample::FineTune'
637 - added class attribute 'Sample::LoopSize'
638 - added method GetInstrument(uint index) to class 'File'
639 - added ReadAndLoop() method to class 'Sample' which is an extension to
640 the normal Read() method to honor the sample's looping information
641 while streaming from disk
642 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
643 'eg2_ctrl_t': replaced this huge enumeration by a structure which
644 reflects the MIDI controller number in case of an ordinary control
645 change controller (this saves a huge switch-case block in the
646 application of the library user)
647 - renamed following attributes in class 'DimensionRegion':
648 'AttenuationContol' -> 'AttenuationController',
649 'InvertAttenuationControl' -> 'InvertAttenuationController',
650 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
651 - minor fix in API documentation for method GetVelocityAttenuation() in
652 class 'DimensionRegion'
653
654 * src/RIFF.cpp, src/RIFF.h:
655 - added additional API documentation
656 - minor fix in Chunk::Read() method (only a minor efficiency issue)
657
658 * src/gigdump.cpp:
659 - added printout of samples' looping informations
660
661 Version 0.6.0 (3 Nov 2003)
662
663 * initial release
