Fri May 5 18:42:06 2017 UTC (6 years, 10 months ago) by schoenebeck
File size: 29776 byte(s)
* Serialization.cpp/.h: Added new methods isModified(),
  setAutoValue(), setIntValue(), setRealValue(),
  setBoolValue(), setEnumValue(), valueAsString() to
  class Archive.
* Serialization.cpp/.h: Archive::rawData(): Automatically
  re-encode new raw data stream if archive had been
  modified (i.e. by remove(), setAutoValue(), etc.).
* Bumped version (4.0.0.svn16).

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

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

166 - Bugfix: Adding a new region in between two existing regions caused the
167 new one being dropped after save operation and the gig file being tainted
168 (chunks at wrong location in the RIFF tree).
169 - Added new method Instrument::MoveTo() which allows to rearrange the order
170 of instruments within the same gig file.
171

232 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
233
234 * src/RIFF.cpp, src/RIFF.h:
235 - bugfix: saving to the same file after the file size had been

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

317 list in v3 files now always has 128 entries, several parameters
318 where incorrectly saved due to an operator precedence mistake
319 - DeleteSample now removes all references to the deleted sample
320 - AddDimension now copies all parameters from existing dimension
321 regions and also makes sure that the samplechannel dimension is
322 placed first in the list of dimensions.

324 parent Region
325 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

346 - added support for custom splits points for other dimensions than
347 velocity (gig v3 feature)
348 - added "smart midi" and "round robin keyboard" dimensions
349 - added new method File::DeleteGroupOnly() which only deletes the given
350 group but moves all its members to another group, the other method,
351 that is File::DeleteGroup() now removes not just the group, but also
352 all the samples that belong to that group
353 - fixed crash which occured on interfering File::DeleteSample() and
354 File::GetNextSample() calls (due to iterator invalidation)
355 - fixed group names which were not saved
356 - fixed group destructor which did not remove the RIFF chunk associated
357 with the group
358 - added Instrument::MoveRegion method
359 - fixed constructor for Region, which did not initialize correctly
360 when used from Instrument::AddRegion
361 - when saving, override the gig::Regions sample reference simply by
362 the region's first dimension region's sample (avoids an exception
363 when trying to save a new instrument)

365 dimension definition fields
366
367 * src/DLS.cpp, src/DLS.h:

500 articulation informations are ignored at the moment
501 (patch by Andreas Persson)
502 - added some file format compatibility checks
503 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
504 never used, because the necessary check was made before

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