Revision 3153 - (show annotations) (download)
Sat May 6 13:43:43 2017 UTC (3 years, 5 months ago) by schoenebeck
File size: 29910 byte(s)
* Serialization.cpp/.h: class Object: Added method
  memberByUID(), and method remove() is now protected,
  class Archive: Added method removeMember().
* Bumped version (4.0.0.svn17).

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
62 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
63 - improved output of non-ascii characters in usage messages
64 - fixed printf format strings
65
66 * src/tools/korg2gig.cpp:
67 - fixed c++11 narrowing warnings
68 - fixed fine tuning which was not translated at all
69
70 * src/tools/gigdump.cpp:
71 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
72 dimension regions
73 - additionally print RIFF chunk file offset and RIFF chunk size of sample
74 data
75 - added and implemented new parameter "--verify" which allows to check
76 the raw wave form data integrity of all samples
77 - added and implemented new parameter "--rebuild-checksums" which allows
78 to recalculate the CRC32 checksum of all samples' raw wave data and
79 rebuilding the gig file's global checksum table (i.e. in case the
80 file's checksum table was damaged)
81 - print samples' CRC32 checksums
82
83 * src/tools/gigextract.cpp:
84 - Fix: if sample name contains a path separator (slash or backslash) then
85 replace them by a minus sign to avoid file system issues.
86
87 * src/tools/gig2stereo.cpp:
88 - Also merge mono sample pairs with non matching loop information if
89 argument --incompatible was given.
90
91 * packaging changes:
92 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
93 auto detect whether it (sh/c)ould output its messages in color.

129 * AKAI file format:
130 - Added Linux/POSIX ported version of libakai. Note that libakai is released
131 under LGPL terms while libgig is released under GPL terms. To handle this

133 separate DLL (.so file).
134 - Fixed Mac OSX support so that the Akai lib files and tools compile without
135 any exotic third party libraries.
136 - Fixed various compilation errors for Windows.

170 new one being dropped after save operation and the gig file being tainted
171 (chunks at wrong location in the RIFF tree).
172 - Added new method Instrument::MoveTo() which allows to rearrange the order
173 of instruments within the same gig file.
174

235 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
236
237 * src/RIFF.cpp, src/RIFF.h:
238 - bugfix: saving to the same file after the file size had been

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

349 - added support for custom splits points for other dimensions than
350 velocity (gig v3 feature)
351 - added "smart midi" and "round robin keyboard" dimensions
352 - added new method File::DeleteGroupOnly() which only deletes the given
353 group but moves all its members to another group, the other method,
354 that is File::DeleteGroup() now removes not just the group, but also
355 all the samples that belong to that group
356 - fixed crash which occured on interfering File::DeleteSample() and
357 File::GetNextSample() calls (due to iterator invalidation)
358 - fixed group names which were not saved

360 with the group
361 - added Instrument::MoveRegion method
362 - fixed constructor for Region, which did not initialize correctly
363 when used from Instrument::AddRegion
364 - when saving, override the gig::Regions sample reference simply by
365 the region's first dimension region's sample (avoids an exception
366 when trying to save a new instrument)

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