Sun Apr 16 23:20:30 2017 UTC (6 years, 11 months ago) by schoenebeck
File size: 28962 byte(s)
* src/gig.cpp: Fixed method File::AddContentOf() which did
  not clone script groups and scripts of passed original file.
* Bumped version (4.0.0.svn14).

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
8 * src/gig.cpp, src/gig.h:
9 - fixed bug in Script::SetGroup: the script chunk wasn't moved
10 - fixed compilation error with clang 3.4
11 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
12 as one single monolithic gig file. In case .gig file is >= 2GB expect a
13 large monolithic file, otherwise if .gig file is < 2 GB check for
14 "extension" files (.gx01, .gx02, ...) instead.
15 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
16 if there were dimensions after the velocity dimension: it only created
17 valid velocity tables for cases of dimensions lower than the velocity
18 dimension.
19 - added new method Sample::VerifyWaveData() which allows to check whether
20 a sample had been damaged for some reason
21 - Fix: samples' CRC checksums were damaged on file structure changes.
22 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
23 - Added new method Sample::GetWaveDataCRC32Checksum().
24 - Changed default value of EG2Release (filter release time) to 60s.
25 - Instruments' default pitch bend range is now +-2 semi tones.
26 - Fixed CRC checksums being wrong sometimes.
27 - Fix: method File::AddContentOf() did not clone script groups and scripts
28 of passed original file.
29
30 * src/DLS.cpp, src/DLS.h:
31 - Sample: wave pool offsets are now 64 bits (to allow support for files
32 larger than 4 GB).
33
34 * src/RIFF.cpp, src/RIFF.h:
35 - added support for RIFF files larger than 4 GB, by default the required
36 internal RIFF file offset size is automatically detected (that is RIFF
37 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
38 automatically use 64 bit offsets), a particular offset size can be forced
39 with a new option added to the RIFF File constructor though
40 - when saving a modified, grown RIFF file, the temporary file size during
41 Save() operation will no longer be larger than the final grown file size
42
43 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
44 - improved output of non-ascii characters in usage messages
45 - fixed printf format strings
46
47 * src/tools/korg2gig.cpp:
48 - fixed c++11 narrowing warnings
49 - fixed fine tuning which was not translated at all
50
51 * src/tools/gigdump.cpp:
52 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
53 dimension regions
54 - additionally print RIFF chunk file offset and RIFF chunk size of sample
55 data
56 - added and implemented new parameter "--verify" which allows to check
57 the raw wave form data integrity of all samples
58 - added and implemented new parameter "--rebuild-checksums" which allows
59 to recalculate the CRC32 checksum of all samples' raw wave data and
60 rebuilding the gig file's global checksum table (i.e. in case the
61 file's checksum table was damaged)
62 - print samples' CRC32 checksums
63
64 * src/tools/gigextract.cpp:
65 - Fix: if sample name contains a path separator (slash or backslash) then
66 replace them by a minus sign to avoid file system issues.
67
68 * src/tools/gig2stereo.cpp:
69 - Also merge mono sample pairs with non matching loop information if
70 argument --incompatible was given.
71
72 * packaging changes:
73 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
74 auto detect whether it (sh/c)ould output its messages in color.
75
76 Version 4.0.0 (14 Jul 2015)
77 * general changes:
78 - minor Makefile fix for parallel make

109
110 * AKAI file format:
111 - Added Linux/POSIX ported version of libakai. Note that libakai is released
112 under LGPL terms while libgig is released under GPL terms. To handle this

343 - fixed constructor for Region, which did not initialize correctly
344 when used from Instrument::AddRegion
345 - when saving, override the gig::Regions sample reference simply by
346 the region's first dimension region's sample (avoids an exception
347 when trying to save a new instrument)
348 - fixed AddDimension() method which did not fill out all mandatory
349 dimension definition fields
350
351 * src/DLS.cpp, src/DLS.h:

535
536 Version 1.0.0 (26 Nov 2004)
537
538 * packaging changes:
539 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
540 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
541 - fixed man pages automake install rule (which didn't work on Mandrake,
542 SuSE and Fedora)
543 - fixed generation of Doxygen API documentation (now also included in
544 RPM and Debian packages)
545
546 * src/gig.cpp, src/gig.h:
547 - fixed / improved accuracy of all three velocity to volume
548 transformation functions a.k.a. 'nonlinear','linear','special'
549 (patch by Andreas Persson)
550 - denormals are filtered from the velocity to volume tables
551 - bugfix for dimension region switching (wrong handling of the release
552 trigger dimension, no bit range check for dimensions of split type
553 'split_type_bit')
554 - fixed panorama value in DimensionRegion (invalid conversion from
555 signed 7 bit to signed 8 bit)
556 - added class attribute 'Layers' to class 'gig::Region'
557 - symbol prototyping of gig::Region (fixes build failure with qsampler)
558
559 * src/gigextract.cpp:
560 - added support for libsndfile (if libaudiofile and libsndfile are
561 available then libsndfile is preferred)
562
563 * src/gigdump.cpp:
564 - added printout for dimension informations (amount, type, bits, zones)
565 - added printout for velocity response curve parameters
566 - added printout for crossfade definitions
567 - added printout for panorama value for each DimensionRegion
568 - replaced printout of DLS Region layer by printout of amount of
569 Gigasampler layers
570
571 Version 0.7.1 (2 Jul 2004)
572
573 * packaging changes:
574 - added libgig.spec and libgig.pc package configurations for generating
575 Redhat packages
576 - header files included on installation.
577 - autotools-generated files removed from CVS repository.
578 - added support for generating Debian packages
579 - version of shared library can be set in configure.in
580
581 Version 0.7.0 (3 May 2004)
582
583 * general changes:
584 - various big endian specific corrections
585 (successfully tested now on PPC)
586 - minor adjustments to avoid compile errors on some systems
587 (using now pow() instead of powl() and --pedantic g++ compiler switch)
588 - libtoolized the library
589 - added man pages for the command line tools
590 (gigextract, gigdump, dlsdump, rifftree)
591
592 * src/gig.cpp, src/gig.h:
593 - fixed bug in decompression algorithm which caused it not to detect
594 the end of a stream
595 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
596 takes the MIDI key velocity value as an argument and returns the
597 appropriate volume factor (0.0 ... 1.0) for the sample to be played
598 back, the velocity curve transformation functions used for this are
599 only an approximation so far
600 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
601 'Sample::LoopSize' which reflected wrong values
602 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
603 measured in sample points instead of byte offset
604 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
605 'Sample::FineTune'
606 - added class attribute 'Sample::LoopSize'
607 - added method GetInstrument(uint index) to class 'File'
608 - added ReadAndLoop() method to class 'Sample' which is an extension to
609 the normal Read() method to honor the sample's looping information
610 while streaming from disk
611 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
612 'eg2_ctrl_t': replaced this huge enumeration by a structure which
613 reflects the MIDI controller number in case of an ordinary control
614 change controller (this saves a huge switch-case block in the
615 application of the library user)
616 - renamed following attributes in class 'DimensionRegion':
617 'AttenuationContol' -> 'AttenuationController',
618 'InvertAttenuationControl' -> 'InvertAttenuationController',
619 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
620 - minor fix in API documentation for method GetVelocityAttenuation() in
621 class 'DimensionRegion'
622
623 * src/RIFF.cpp, src/RIFF.h:
624 - added additional API documentation
625 - minor fix in Chunk::Read() method (only a minor efficiency issue)
626
627 * src/gigdump.cpp:
628 - added printout of samples' looping informations
629
630 Version 0.6.0 (3 Nov 2003)
631
632 * initial release
