Mon May 8 17:18:07 2017 UTC (2 years, 10 months ago) by schoenebeck
File size: 30136 byte(s)
* class Archive: Added methods name() and setName().
* class Archive: Added methods comment() and setComment().
* class Archive: Added methods timeStampCreated(),
  timeStampModified(), dateTimeCreated() and
  dateTimeModified().
* Bumped version (4.0.0.svn18).

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
11 * src/gig.cpp, src/gig.h:
12 - fixed bug in Script::SetGroup: the script chunk wasn't moved
13 - fixed compilation error with clang 3.4
14 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
15 as one single monolithic gig file. In case .gig file is >= 2GB expect a
16 large monolithic file, otherwise if .gig file is < 2 GB check for
17 "extension" files (.gx01, .gx02, ...) instead.
18 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
19 if there were dimensions after the velocity dimension: it only created
20 valid velocity tables for cases of dimensions lower than the velocity
21 dimension.
22 - added new method Sample::VerifyWaveData() which allows to check whether
23 a sample had been damaged for some reason
24 - Fix: samples' CRC checksums were damaged on file structure changes.
25 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
26 - Added new method Sample::GetWaveDataCRC32Checksum().
27 - Changed default value of EG2Release (filter release time) to 60s.
28 - Instruments' default pitch bend range is now +-2 semi tones.
29 - Fixed CRC checksums being wrong sometimes.
30 - Fix: method File::AddContentOf() did not clone script groups and scripts
31 of passed original file.
32 - Added support for serializing & deserializing DimensionRegion
33 objects (and crossfade_t and leverage_ctrl_t objects).
34
35 * src/DLS.cpp, src/DLS.h:
36 - Sample: wave pool offsets are now 64 bits (to allow support for files
37 larger than 4 GB).
38
39 * src/RIFF.cpp, src/RIFF.h:
40 - added support for RIFF files larger than 4 GB, by default the required
41 internal RIFF file offset size is automatically detected (that is RIFF
42 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
43 automatically use 64 bit offsets), a particular offset size can be forced
44 with a new option added to the RIFF File constructor though
45 - when saving a modified, grown RIFF file, the temporary file size during
46 Save() operation will no longer be larger than the final grown file size
47
48 * src/Serialization.cpp, src/Serialization.h:
49 - Archive: Added method isModified().
50 - Archive: Added method setAutoValue().
51 - Archive: Added method setIntValue().
52 - Archive: Added method setRealValue().
53 - Archive: Added method setBoolValue().
54 - Archive: Added method setEnumValue().
55 - Archive: Added method valueAsString().
56 - Archive::rawData(): Automatically re-encode new raw data stream if
57 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
58 - Object: Added method memberByUID().
59 - Object: remove() method is now protected.
60 - Archive: Added method removeMember().
61 - Archive: Added methods name() and setName().
62 - Archive: Added methods comment() and setComment().
63 - Archive: Added methods timeStampCreated(), timeStampModified(),
64 dateTimeCreated() and dateTimeModified().
65
66 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
67 - improved output of non-ascii characters in usage messages
68 - fixed printf format strings
69
70 * src/tools/korg2gig.cpp:
71 - fixed c++11 narrowing warnings
72 - fixed fine tuning which was not translated at all
73
74 * src/tools/gigdump.cpp:
75 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
76 dimension regions
77 - additionally print RIFF chunk file offset and RIFF chunk size of sample
78 data
79 - added and implemented new parameter "--verify" which allows to check
80 the raw wave form data integrity of all samples
81 - added and implemented new parameter "--rebuild-checksums" which allows
82 to recalculate the CRC32 checksum of all samples' raw wave data and
83 rebuilding the gig file's global checksum table (i.e. in case the
84 file's checksum table was damaged)
85 - print samples' CRC32 checksums
86
87 * src/tools/gigextract.cpp:
88 - Fix: if sample name contains a path separator (slash or backslash) then
89 replace them by a minus sign to avoid file system issues.
90
91 * src/tools/gig2stereo.cpp:
92 - Also merge mono sample pairs with non matching loop information if
93 argument --incompatible was given.
94
95 * packaging changes:
96 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
97 auto detect whether it (sh/c)ould output its messages in color.
98

132
133 * AKAI file format:
134 - Added Linux/POSIX ported version of libakai. Note that libakai is released
135 under LGPL terms while libgig is released under GPL terms. To handle this
136 license difference appropriately the AKAI support part is built as
137 separate DLL (.so file).
138 - Fixed Mac OSX support so that the Akai lib files and tools compile without
139 any exotic third party libraries.
140 - Fixed various compilation errors for Windows.

172 - Added support for custom progress notification while saving to gig file.
173 - Bugfix: Adding a new region in between two existing regions caused the
174 new one being dropped after save operation and the gig file being tainted
175 (chunks at wrong location in the RIFF tree).
176 - Added new method Instrument::MoveTo() which allows to rearrange the order
177 of instruments within the same gig file.

239 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
240
241 * src/RIFF.cpp, src/RIFF.h:
242 - bugfix: saving to the same file after the file size had been

312 - write support: DLSID is now generated on the file and the
313 instruments
314 - write support: improved the default values for dimension region
315 parameters
316 - more write support fixes: crossfade parameters were not saved,
317 v3 dimension limits were not correctly initialized and saved
318 when dimensions were added or deleted, v3 wave pool offsets were
319 not saved correctly
320 - write support: 24 bit samples can now be written

331 parent Region
332 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

354 velocity (gig v3 feature)
355 - added "smart midi" and "round robin keyboard" dimensions
356 - added new method File::DeleteGroupOnly() which only deletes the given
357 group but moves all its members to another group, the other method,
358 that is File::DeleteGroup() now removes not just the group, but also
359 all the samples that belong to that group
360 - fixed crash which occured on interfering File::DeleteSample() and
361 File::GetNextSample() calls (due to iterator invalidation)

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

511 never used, because the necessary check was made before
512 initialization)
513 - fixed crossfade points order (structure for big endian and little
514 endian systems was interchanged)
515 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
516 - fixed crash which occured when patches did not have a sample assigned
517 to their region or dimension region (patch by Andreas Persson)
518 - support for compressed mono samples
519 - experimental support for compressed 24 bit samples
520 - fixed decompression on big-endian CPUs
521 - fixed decompression bug that truncated the last block of samples
522 - external decompression buffers can now be used for streaming samples
523 to avoid race conditions in case of multiple streaming threads
524 - added pre-calculated sample attenuation parameter
525 - added v3 "random" and "round robin" dimensions
526 - implemented progress indicator callback mechanism for loading
527 instruments and samples
528 - added functions libraryName() and libraryVersion()
529
530 * src/DLS.cpp, src/DLS.h:

537 position within the body of the given list chunk
538 - added functions libraryName() and libraryVersion()
539
540 * src/rifftree.cpp:
541 - added command line switch -v to show rifftree's revision and the used
542 libgig version
543
544 * src/dlsdump.cpp:
545 - added command line switch -v to show dlsdump's revision and the used
546 libgig version
547
548 * src/gigdump.cpp:
549 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
550 LoopPlayCount
551 - added command line switch -v to show gigdump's revision and the used
552 libgig version
553
554 * src/gigextract.cpp:
555 - support for compressed mono samples and compressed 24 bit samples
556 - added command line switch -v to show gigextract's revision and the
557 used libgig version
558
559 Version 1.0.0 (26 Nov 2004)
560
561 * packaging changes:
562 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
563 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
564 - fixed man pages automake install rule (which didn't work on Mandrake,
565 SuSE and Fedora)
566 - fixed generation of Doxygen API documentation (now also included in
567 RPM and Debian packages)
568
569 * src/gig.cpp, src/gig.h:
570 - fixed / improved accuracy of all three velocity to volume
571 transformation functions a.k.a. 'nonlinear','linear','special'
572 (patch by Andreas Persson)
573 - denormals are filtered from the velocity to volume tables
574 - bugfix for dimension region switching (wrong handling of the release
575 trigger dimension, no bit range check for dimensions of split type
576 'split_type_bit')
577 - fixed panorama value in DimensionRegion (invalid conversion from
578 signed 7 bit to signed 8 bit)
579 - added class attribute 'Layers' to class 'gig::Region'
580 - symbol prototyping of gig::Region (fixes build failure with qsampler)
581
582 * src/gigextract.cpp:
583 - added support for libsndfile (if libaudiofile and libsndfile are
584 available then libsndfile is preferred)
585
586 * src/gigdump.cpp:
587 - added printout for dimension informations (amount, type, bits, zones)
588 - added printout for velocity response curve parameters
589 - added printout for crossfade definitions
590 - added printout for panorama value for each DimensionRegion
591 - replaced printout of DLS Region layer by printout of amount of
592 Gigasampler layers
593
594 Version 0.7.1 (2 Jul 2004)
595
596 * packaging changes:
597 - added libgig.spec and libgig.pc package configurations for generating
598 Redhat packages
599 - header files included on installation.
600 - autotools-generated files removed from CVS repository.
601 - added support for generating Debian packages
602 - version of shared library can be set in configure.in
603
604 Version 0.7.0 (3 May 2004)
605
606 * general changes:
607 - various big endian specific corrections
608 (successfully tested now on PPC)
609 - minor adjustments to avoid compile errors on some systems
610 (using now pow() instead of powl() and --pedantic g++ compiler switch)
611 - libtoolized the library
612 - added man pages for the command line tools
613 (gigextract, gigdump, dlsdump, rifftree)
614
615 * src/gig.cpp, src/gig.h:
616 - fixed bug in decompression algorithm which caused it not to detect
617 the end of a stream
618 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
619 takes the MIDI key velocity value as an argument and returns the
620 appropriate volume factor (0.0 ... 1.0) for the sample to be played
621 back, the velocity curve transformation functions used for this are
622 only an approximation so far
623 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
624 'Sample::LoopSize' which reflected wrong values
625 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
626 measured in sample points instead of byte offset
627 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
628 'Sample::FineTune'
629 - added class attribute 'Sample::LoopSize'
630 - added method GetInstrument(uint index) to class 'File'
631 - added ReadAndLoop() method to class 'Sample' which is an extension to
632 the normal Read() method to honor the sample's looping information
633 while streaming from disk
634 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
635 'eg2_ctrl_t': replaced this huge enumeration by a structure which
636 reflects the MIDI controller number in case of an ordinary control
637 change controller (this saves a huge switch-case block in the
638 application of the library user)
639 - renamed following attributes in class 'DimensionRegion':
640 'AttenuationContol' -> 'AttenuationController',
641 'InvertAttenuationControl' -> 'InvertAttenuationController',
642 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
643 - minor fix in API documentation for method GetVelocityAttenuation() in
644 class 'DimensionRegion'
645
646 * src/RIFF.cpp, src/RIFF.h:
647 - added additional API documentation
648 - minor fix in Chunk::Read() method (only a minor efficiency issue)
649
650 * src/gigdump.cpp:
651 - added printout of samples' looping informations
652
653 Version 0.6.0 (3 Nov 2003)
654
655 * initial release
